Better known for its steel detailing capabilities Tekla Structures is actually material agnostic. It's a powerful software tool for 3D modelling and outputting information for fabrication. For example, in Tekla Structures you don't need to do your own assemblies, it's fully automated with cutting instructions and drawings for fabrication far superior to those of the competition. We asked someone with no experience of Tekla Structures to sit down with Craig Johnson, Account Executive at Trimble, and ask the most basic questions regarding the software. If you want to understand what Tekla Structures is all about, this interview is set to answer all your questions! What is Tekla Structures? Tekla Structures is 3D BIM software for modelling structures. With Tekla Structures you can create, combine, manage and distribute accurate multi-material models full of construction information. You can use Tekla Structures for design, detailing and information management from conceptual planning to fabrication and construction on-site. Who is it for? Tekla Structures is used by structural engineers, designers, detailers, fabricators, contractors and project managers. "There's a lot of different markets that Tekla Structures is used in currently and it's expanding all the time but essentially, it's for those of you who want to do your modelling, your detailing and then your drawing production and all of the manufacturing information that comes with that." What does it do? Tekla Structures is a powerful structural BIM software, it enables you to create, combine, manage and share information-rich accurate 3D models. "Tekla Structures can be used by anyone really, anyone involved in the project who's going to get value from the 3D detailed model. So it could be someone who just wants to view the model, it could be someone who just wants to do an estimate model. I guess the main breadth is detailers, they would use Tekla Structures for producing a model, and from there they'd create detailed components, such as connections, rebar, things like that. Getting that information down into 2D is the next stage, that would be your general arrangement drawings, fabrication drawings; all that information is automatically generated from the model. Another step would be generating any manufacturing information; that could be NC files, rebar bending schedules and files. Once you've got that 3D model there's so much more you can do with it. Rather than keeping it siloed within your company, you can share it out to the architects, engineers, anyone who's involved in the project can get the benefit of that fully detailed model." Why would I use Tekla Structures? "From my personal experience, moving from that 2D environment, from 2D drawings to a 3D modelling environment, it's transformational for anyone who's using it. You use Tekla Structures to design as you would fabricate, or design as you would build. As you are building the model you get an understanding of it, you can rotate around and get a real feel for what you build. As you work you collaborate with everyone, everyone can view the model and make comments. That collaboration within the 3D model, it's invaluable! Everyone is on the same page as the model is being created. Once you're ready you can automatically generate drawings, the stuff that you spend hours and hours doing in the 2D environment can be done in minutes. The manufacturing information; NC files for CNC, you can't get that from a 2D environment, here it's all just generated automatically. That's the biggest benefit that I see personally in using Tekla Structures and for anyone who's looking to get involved with the trial." Estimation and bidding In Tekla Structures you can generate accurate quantity take-offs and quotations based on the 3D model, including all materials, time and costs. "We see Tekla Structures used extensively in the estimation and bidding stage. You can take 2D information from architects or 3D information from the likes of Revit as an architectural package, convert that into IFC and then you've got your bill of materials ready to go. That can be done in a matter of minutes. All the information is within the model, you can obtain the linear weights of your material, and get an idea of the lengths that you'd need to cut, so you can really do your forward planning at an early stage and get everyone on board early. If you share that out through Trimble Connect, then you can get people commenting on the 3D model at that early stage as well." Project planning and execution Tekla Structures enables you to coordinate all disciplines, resolve conflicts and plan the project before construction begins. You can generate plans, reports and drawings directly from the 3D model, and utilise object data and location information to plan erection sequences, crane locations and resources. It is also possible to add scheduling and sequence information to the model. "So we see Tekla Structures used in the project planning execution stage quite extensively. Using the 3D model you can actually plan for things like lifting. If you've got a really heavy object or really awkward object that needs to be lifted, let's say in a city centre, then you're going to need a really solid lifting plan because you're going to have road closures, things like that. You're going to have to understand where your craneage is. Tekla Structures enables you to put all that within the model and plan for lifting. In offsite construction we see the use of sequences, you can put your sequencing within Tekla Structures and do your planning from there. You can also plan for your production and plan for erection on site. Everything's in there as tools within the software that you can use." Design, detailing and fabrication "Tekla Structures is a great tool for design and detailing, we interface with a lot of different analysis software, the main one being Tekla Structural Designer which of course is part of the Tekla portfolio. Once you've got a model with your steel sections designed, you can then start doing your detailing, so you would add your connection details, any kind of simple connections, moment connections, they can all be done within the software. You can also create custom components if you want to start automating the connections and designing your own connections within the system as well. The detailing stage is where Tekla Structures really comes into its own, because you can start generating the fabrication drawings in minutes. They're all done automatically. The drawings use templates which you can customise to your own company standards. We supply default versions you can use which are really good as well. You would use Tekla Structures for design and detailing for any kind of project that you're involved with whether that's steel, concrete, timber, light metal framing, offsite volumetric. The main benefit is the level of detail that you can get, whether that's connections, rebar, embeds, anything like that, you can get it all in the one model and you can see how they all interface with each other as well. You can perform clash-checking, and produce an advanced bill of materials on things such as bolts, plates, embeds, rebar; all that can be pulled from the model at an early stage and then sent in to manufacture. The output you can get from Tekla Structures is pretty extensive. You can do CNC output; so that could be saw drill lines, CNC machines for plates. If you're doing precast or rebar, you can get all of your bar bending information from the model as well. You can even go as far as actually putting layout points in the model and exporting them out to real-life coordinates on site." What features does Tekla Structures have? Tekla Structures is a flexible software for all types of projects. It enables you to speed up your work with an extensive library of standard connections for different types of projects. You can create a detailed, constructible 3D model of any size structure, from small secondary steelwork to skyscrapers. "The main feature of Tekla Structures is the ability to model any kind of material. So whether that's steel, concrete, timber, light metal framing, you can do it all within the one system. It's really good if you need to do an integrated model or hybrid type of model, you've got all the materials available in the software." Up-to-date drawings From Tekla Structures, you can generate general arrangement drawings, single-part drawings, assembly drawings, cast unit drawings, and multidrawings. Tekla Structures drawings are always up to date. "When it comes to the 2D drawings having that 2D information and being able to generate it quickly is really important. The drawings are all automatic, they all link back to the model. Any updates in the model and the drawings automatically update in the background." API and collaboration Components are tools that you can use to connect parts in the model. Tekla Structures contains a wide range of predefined system components by default. However, you can define customised connections, parts, seams, and details for your project. These are called custom components. Using the Tekla Open API, you can develop your own applications and additional features for Tekla Structures, these are referred to as extensions. Alternatively, you can download extensions created by others from Tekla Warehouse. "There is a catalogue of standard components within the software that can be used in all of your day-to-day detailing. You also have the flexibility through custom components and API to start generating your own company specific components. And we can't forget the fully detailed model and our ability to collaborate with it. Sending the model out to all stakeholders so they can get involved with its development at an early stage and comment on it as things progress. When you create a Tekla Structures project you also create a Trimble Connect project in the background. In Tekla Structures you'll find a tab named Trimble Connect, once you've got your model, no matter what stage of detail it's at, you can upload it to Trimble Connect. Anyone who's involved in that project can then come in and view that iteration of the model, and whenever you're ready to update it, you just upload the model again and then the latest iteration will become available for people to see. It's a really slick interface." Any size structure "Another key benefit of Tekla Structures is the ability to model any size structure. We see it used for really small secondary steelwork, stairs, handrails, things like that, right up to skyscraper level buildings. So it's versatile enough that it can be used on any sized project no matter what." Why does Tekla Tedds integrate with Tekla Structures? "One of our main focuses in the last couple of years has been to enable our customers to use more of our software in conjunction with each other." Tekla Tedds Integrator allows you to link Tekla Tedds calculation documents to your Tekla Structures model. You can link existing documents or create new documents, which you or other Tekla Structures users can then easily modify or review during your BIM workflow. The integration reduces the amount of manual work that the detailer or engineer has to undertake in Tekla Structures thus improving productivity. "We've created the integrator tool between Tekla Tedds and Tekla Structures to enable Tekla Structures users to send information and any components that they have within their Tekla Structures model into Tekla Tedds to perform the design. You can then send that information back into Tekla Structures and embed the calculation in the file for use further down the line in the project." To find out more, see: Tekla Tedds Integrator user guide Why does Tekla Structural Designer integrate with Tekla Structures? Tekla Structural Designer is a model-based 3D tool for analysis and design of both concrete and steel members in multi-material structures. The integration between Tekla Structural Designer and Tekla Structures allows you to link the theoretical analysis and design model to the constructible model. "Tekla Structures integrates with Tekla Structural Designer, you can start a model in Tekla Structural Designer, get your design correct and then once you're ready to push that through, it's a direct transfer to Tekla Structures. From there you can do your detailed design, that'll be adding things like your rebar, steel connections, precast design, anything you want to do to take that model further into that detail and manufacturing stage." You are able to seamlessly transfer 3D models and design intent data to Tekla Structures, the information transferred is the physical information associated with the structure such as geometry, section sizes and grade as well as attributed data. The import process is very fast and accurate, generating a Tekla Structures model with all elements and profiles that are contained within the Tekla Structural Designer model. Once in Tekla Structures an accurate detailed structural model can be produced, along with drawings and material lists. The initial model can be started in either Tekla Structures or Tekla Structural Designer, depending on the project needs. You can import and export many times, and make use of the effective change management functionality. How easy is it to learn Tekla Structures? "When it comes to learning material, you've got a few options available. On Trimble Learn, our online training platform, you'll find the First Steps tutorial for Tekla Structures. In fact, when you open the software, you should see a notification prompting you to view the tutorial. The other thing you've got that's built into the software is the Instructor pane. If you hover over an object on the ribbon the Instructor pane will assist you by giving you a step-by-step guide on what to do with that function. Another thing to look out for is along the bottom ribbon of the software, you get guidance there as well, it tells you where to click and what the sequence needs to be. So keep an eye out for that!" The eLearning for Tekla Structures is free. You can register for it with your Trimble ID, it'll help get you started straight away with the trial. If you do want to progress further with the licence and with training, then you have options available for what we call the intermediate training. This is a training course that we host either in-person or online and details can be sent out if you need more information on that further down the line." What is Tekla Model Sharing? With Tekla Model Sharing a team can work efficiently within one model regardless of location and time zones. Team members can work both simultaneously and at different times. Each user has a local version of the model on their computer. The model data is shared and synchronised over the Internet, and stored to a cloud-based Tekla Model Sharing service. It is possible for team members to work offline as an Internet connection is only needed when sharing the model changes. "Tekla Model Sharing is a cloud platform that we provide where you can host your models. With Tekla Model Sharing you can actually work with other Tekla users on the same project whether that's in-house or externally. You have the option to do that." What is Trimble Connect Business Premium? "Trimble Connect Business Premium is a collaboration tool, it enables you to send data files between each of the stakeholders. You can access and view different models, whether that be Tekla Structural Designer, Tekla Structures or Revit files, and you are able to actually look at that data and interrogate the models. You can send information to site should you need to, to other users of Trimble Connect, who can access it through their phones, tablets and laptops. It enables you to share data as effectively as possible between multiple stakeholders." Jamie Howarth Watch the video blog Article From: Trimble.com

With advances in design and 3D CAD software, prototypes can now easily come alive on a computer screen. Modern workflows have ushered in a new class of richly functional applications that have redefined what can be designed in a given length of time. 3D modeling has resolved many shortcomings associated with outdated processes and has increased functionality across design teams. Let’s explore a few ways in which 3D modeling and 3D CAD software have vastly improved the design process. 1. Costs savings Traditional 2D modeling makes it difficult to get a true feel for a design’s form factor during the prototyping stage of design. This forces product designers to manufacture prototype after prototype to reflect every noteworthy design change. Thus resulting in heavy resource costs, which magnify at scale when developing multiple products simultaneously. Ultimately, companies would likely prefer to save these raw materials for actual production. 3D modeling breathes life into the prototyping process. Designers can manipulate their models and inspect them from every angle in a digital environment before producing a physical prototype. Teams are no longer restricted to “flat” design, making it much easier to evaluate tweaks without expending resources. 2. Quick flaw recognition Spotting design weaknesses becomes much easier when people can apply other layers (and tests) to designs in real time. Take stress mapping, for example, where colored topography highlights areas of concern. This is key for products exposed to different stressors like heat, pressure, and torsion. Today’s designs incorporate a variety of different geometries—complex shapes are the new norm. Unfettered inspection of models allows product designers to inspect every nook and cranny of a design, ensuring each imperfection is identifiable and correct for the next iteration. 3. Ease of use and efficiency Digital design makes it easy to quickly apply a host of changes to each iteration, which usually involves only a click, selection, or toggle. The improved visualization offered through 3D modeling allows the user to preview these changes from all perspectives, making it easy to verify physical and functional changes and sharpen aesthetics. While traditional 2D designs are cumbersome and take longer to make, 3D modeling allows the production of newer versions in under 15 minutes (especially with tools like configurations in Autiodesk Fusion). The exceptional user-friendliness of CAD tools like Fusion reduces the software learning curve, keeping teams agile and reducing training time. 4. Unparalleled detail and accuracy 3D models let teams construct any shape imaginable while retaining production capability and help visions come together with relative ease. 3D modeling provides a level of design depth that rough sketches or 2D designs cannot, such as improved control over details. On the collaboration side, meticulous details make it easier to convey the specifics behind a given design. Design teams are no longer in silos. With tools like Fusion, they can easily communicate with other teams and stakeholders in real time. 3D models also let teams inject more detail, thus helping everyone stay on the same page from idea to production. Why Autodesk Fusion? 3D tools are inherently modern, and remote work is the hallmark of the modern age. Intuitive, user-friendly solutions like Fusion allow team members to communicate from afar — via real-time collaboration tools like commenting, annotations, and more. Being out of the office doesn’t mean team members have to be out of the loop. Cloud software lets you pump out design after design without being constantly at your desk. Autodesk Fusion is for professional product designers and hobbyists alike. In addition to standard 3D modeling tools, Fusion offers an extensive list of additional features. These include parametric design, electronics design, generative design, 3D printing capabilities, and more. It also offers a variety of plugins and extensions to make your 3D modeling workflow even more seamless.   Article From: www.aitodesk.com

Adaptive reuse is changing how we build—cutting emissions, saving resources, and breathing new life into old spaces. Explore the benefits, trends, and real-world examples. Adaptive reuse repurposes old buildings for modern needs, reducing demolition waste and preserving historic structures. The built environment contributes to 42% of global carbon emissions, making adaptive reuse an essential strategy for sustainable development. Emerging trends include converting underutilized office spaces into residential or mixed-use developments and meeting urban demands while promoting sustainability. Adaptive reuse supports economic growth, community revitalization, and environmental preservation by transforming existing structures into vibrant, multifunctional spaces. Adaptive reuse is breathing new life into old buildings and transforming the architecture, engineering, construction, and operations (AECO) industry in the process. Rather than demolishing structures, adaptive reuse repurposes them for modern needs, preserving history while reducing waste and minimizing environmental impact. With the built environment responsible for about 42% of global carbon emissions, adaptive reuse is gaining traction as a critical strategy for sustainable development. Trends like converting underutilized office spaces into housing or mixed-use developments are on the rise; RentCafe’s Adaptive Reuse report shows that office building conversions make up 38% of the 147,000 residential adaptive reuse projects in the United States, showcasing the potential of this approach to meet evolving urban needs while supporting economic and ecological goals. What is adaptive reuse? Adaptive reuse repurposes existing buildings for new uses, cutting waste and carbon while preserving history. It’s a sustainable alternative to demolition, supported by tools like BIM and reality capture for efficient planning and design. This approach lowers embodied carbon, reduces costs, and helps meet urgent climate and housing goals. Types of adaptive reuse in architecture Historic preservation aims to preserve a building's original form and materials. Adaptive reuse can take many forms. In architecture, adaptive reuse refers to repurposing an existing structure for new use, such as turning vacant buildings into schools, public parks, offices, or apartments. Historic preservation Both adaptive reuse and historic preservation can save historic buildings, but the approaches are different. Adaptive reuse aims to repurpose an old building or site for new uses; this process is often viewed as a compromise between preservation and demolition. Historic preservation, in contrast, sustains a building’s existing form, integrity, and materials. Exterior additions and alterations don’t fall within the scope of this treatment, but minimally invasive mechanical, electrical, and plumbing (MEP) upgrades and work required to meet new building codes are generally appropriate, according to standards published by the National Park Service, which administers the National Register of Historic Places. One of the biggest benefits of adaptive reuse over historic preservation is having the flexibility to use new, efficient architectural materials while still paying homage to the structure’s history. This approach improves a building’s performance while lowering its carbon footprint. Renovation Adaptive reuse, by design, implies renovation. While renovation is generally limited to repairing and refinishing a building but preserving the building’s original purpose, adaptive reuse implies a transformation of use. Integration Integration involves constructing around an original structure, preserving that structure while encompassing it inside a new building. One striking example of integration is Denmark’s Jægersborg Water Tower, which was converted by Dorte Mandrup into student housing. Facadism Facadism is the urban design tactic of preserving a building’s facade while demolishing the bulk of the rest of the building to replace it with a modern structure. The process is known as a facadectomy; it preserves the streetscape view but is expensive because the facade, which is usually built from fragile historical materials, needs to be supported and protected during construction. Historic-preservation advocates tend to view facadism as a poor substitute for preserving an entire building, but supporters consider it a better alternative than erasing a city’s historic footprint. Infrastructure While most adaptive reuse focuses on buildings, some of the most innovative adaptive reuse projects transform outdated or unused infrastructure into community features. A famous example of adaptive reuse in infrastructure is New York City’s High Line. Once an elevated railway known as the West Side Elevated Line, this lofty park winds through nearly 1.5 miles of lower Manhattan and features more than 500 species of plants and trees, resting spaces and viewing balconies, an open-air food market, and ramp accessibility. Benefits of adaptive reuse Adaptive reuse projects offer opportunities to integrate energy-saving technologies such as solar panels. Adaptive reuse offers powerful benefits across sustainability, financial growth, cultural preservation, and community revitalization. Here’s how it’s transforming the built environment. Cultural preservation Adaptive reuse helps protect cultural heritage by preserving historic buildings and maintaining the architectural character of cities. This fosters a sense of continuity and identity for communities and also promotes tourism, attracting visitors interested in heritage and history. Unique spaces A commitment to adaptive reuse often leads to distinctive character-rich spaces that stand out from more uniform new construction. Flexibility follows aesthetics as many buildings are repurposed for multiple uses and easily adapted to future needs. Community engagement Revitalizing an old building often draws interest and involvement from the surrounding community. This can foster a sense of ownership among residents and enhance community pride, creating stronger social ties. Energy efficiency potential Older buildings may not be as energy-efficient; adaptive reuse projects offer opportunities to integrate modern energy-saving technologies like insulation, solar panels, and smart systems, enhancing the building’s performance and reducing long-term operational costs. 5 examples of adaptive reuse Lake|Flato transformed a garage roof into a courtyard structure at its 311 Third St. headquarters. Image courtesy of Robert G Gomez. Lake|Flato’s adaptive reuse headquarters: A showcase of sustainability Lake|Flato transformed a 100-year-old car dealership in San Antonio into its new, sustainable headquarters. Instead of building anew, the architecture firm embraced adaptive reuse, turning the historic structure into a future-ready, hybrid workplace. The project, called “Living the Dream,” preserved key elements such as the original brick facade and concrete beams, while introducing modern touches, including a year-round courtyard created from a former garage. This outdoor space fosters connection with nature and serves as an extension of the office, providing space for work and social events. Using digital tools such as laser scanning and 3D modeling with Autodesk Revit, the firm optimized material reuse, daylighting, and energy performance. These strategies helped the project align with Lake|Flato’s sustainability goals, with certifications for Zero Carbon and WELL on the horizon. The adaptive reuse of the building minimized embodied carbon and also enhanced employee well-being, demonstrating how old spaces can be revitalized to serve modern needs sustainably. Building 12, a former World War II ship-hull factory, was chosen to anchor the 28-acre Pier 70 in San Francisco as an example of building adaptive reuse. Building 12: A landmark adaptive reuse at San Francisco’s Pier 70 Building 12, a World War II-era ship-hull factory, anchors the 28-acre Pier 70 redevelopment in San Francisco. As part of the project’s first phase, the historic building underwent a transformative adaptive reuse to preserve its industrial past while preparing for future challenges such as rising sea levels. Developers chose to preserve the building’s iconic steel columns and corrugated siding, reducing embodied carbon emissions. However, lifting the entire structure by 10 feet was necessary to address sea-level rise projections, a monumental task that limited some of the carbon savings. Despite these challenges, the project exemplifies adaptive reuse, blending history with innovation. Once completed in the mid-2020s, Building 12 will feature maker studios, retail spaces, and offices, becoming a vibrant hub of creativity and commerce. Perkins&Will, the architects behind the project, used advanced tools like Autodesk Revit to ensure precision in the restoration process, emphasizing the importance of reusing existing structures to minimize carbon impact. Building 12 is set to be a symbol of urban renewal, showcasing how old buildings can be revitalized into modern, sustainable, mixed-use spaces while honoring their industrial heritage. The Standard London: A 1970s Brutalist building revived as a boutique hotel In the heart of London’s King’s Cross neighborhood, Orms architects transformed a 1970s Brutalist office building into a chic 266-room boutique hotel, The Standard London. This adaptive reuse project preserved the building’s postwar architectural heritage while introducing bold design elements, including three new stories for a restaurant, bar, and rooftop terrace. Using Autodesk Revit and 3D modeling, the project team collaborated with MEP and structural consultants to retain as much of the original structure as possible. These digital tools helped integrate modern systems for heating, cooling, and lighting, optimizing the building’s sustainability while reducing embodied carbon emissions. The Standard London demonstrates how adaptive reuse can transform outdated structures into modern, sustainable spaces, preserving history and minimizing environmental impact. The project sets a high bar for future retrofits, embracing reuse as a key strategy in sustainable urban development. The architects at Broadway Malyan and engineers at A400 used Autodesk AutoCAD and Revit to plan the new World of Wine site. World of Wine: Revitalizing 200-year-old port wine warehouses into a vibrant cultural hub The World of Wine (WOW) in Porto, Portugal, is a stunning example of adaptive reuse, transforming centuries-old port wine warehouses into a dynamic arts and entertainment complex. Led by architecture firm Broadway Malyan, the project repurposed hundreds of 200-year-old structures into a tourist hotspot featuring seven museums, 14 restaurants, a wine school, galleries, and shops—all while preserving the site’s historical significance. Located in Vila Nova de Gaia, the warehouses were originally built to store port wine but fell into disrepair after wine storage laws changed. The 37,000-square-meter (398,000-square-foot) site, completed in 2020, blends contemporary design with the original granite brickwork and wooden beams. In areas where structures were beyond repair, facades were preserved to honor the buildings’ heritage. Using Autodesk AutoCAD and Revit, the project team coordinated complex renovations, reinforced foundations, and integrated modern amenities like air conditioning and parking while preserving the historical integrity of the site. The meticulous planning ensured the project stayed nearly on schedule, despite challenges posed by the COVID-19 pandemic. Now a thriving cultural hub, WOW has won numerous awards and solidified Porto’s status as a top tourist destination, merging history with modern attractions.

This innovative development connects a restored 19th-century school building to a new medical facility, creating a mixed-use hub that combines history with modern design. The project preserved 80% of the original building, blending it with a new, sustainable structure while adding community spaces including kitchens, a gym, and a nursery school. Designed for sustainability, the new building maximizes natural light, features a green roof for cooling, and includes energy-efficient systems. The firm’s use of BIM technology was crucial for the project’s success, marking a pivotal moment in its digital transformation. Autodesk Revit enabled cross-continental collaboration, with project teams in Chile and Spain working seamlessly through shared digital models. This advanced coordination helped meet the project’s complex requirements, from restoring the historic building to achieving ambitious sustainability goals. The Matta Sur Complex now serves as a model for blending tradition and innovation, providing Santiago’s community with a sustainable, functional, and culturally significant space. New technologies in adaptive reuse architecture 3D scanning captures precise building data—particularly useful in older structures with incomplete plans. In adaptive reuse projects, advanced technologies and sustainable practices enhance efficiency, cost-effectiveness, and environmental responsibility. Key tools like building information modeling (BIM), 3D scanning and printing, the Internet of Things (IoT), smart systems, and sustainable materials are transforming this process. BIM BIM creates detailed digital models that allow teams to assess buildings accurately, minimizing surprises during adaptation. It also facilitates real-time collaboration and virtual simulations, helping ensure aesthetic and structural goals are met. 3D scanning and printing 3D scanning and printingrevolutionize documentation and restoration. Scanning captures precise building data, especially in older structures with incomplete plans, while 3D printing enables the creation of custom architectural elements, ideal for replicating historical features. IoT and smart systems IoT and smart systems improve energy efficiency and building performance by automatically adjusting systems such as HVAC and lighting based on occupancy. IoT devices provide real-time data, enabling predictive maintenance, while smart controls add modern conveniences to older buildings. Sustainable materials Sustainable materials are central to adaptive reuse, reducing environmental impact by reusing original materials such as wood and brick. Eco-friendly upgrades, such as low-VOC paints and green insulation, enhance health and sustainability, while energy-efficient retrofits like solar panels and green roofs improve long-term performance. Together, these technologies and materials blend old and new, making adaptive reuse a powerful approach to evolving the built environment. Sustainability in adaptive reuse Adaptive reuse presents opportunities to reuse materials like salvaged wood during renovation. Adaptive reuse is one of the most impactful ways to build sustainably—preserving materials, reducing carbon emissions, and extending the life cycle of the built environment. Environmental impact of adaptive reuse Adaptive reuse has a significant environmental advantage, reducing construction waste and lowering the carbon footprint compared to new builds. By repurposing existing materials, it limits the need for new resource extraction and energy-intensive processes. Upgrading older buildings with energy-efficient systems also cuts operational energy use, reducing greenhouse gas emissions and conserving natural resources. LEED certification and adaptive reuse Adaptive reuse is particularly well-suited for achieving LEED certification, integrating several key sustainability strategies. By preserving existing structures, it reduces environmental impact through the reuse of the building shell, minimizing the need for new materials. Using sustainable materials, such as recycled and reclaimed resources, further aligns with LEED credits. Modernizing buildings with energy-efficient HVAC, lighting, and insulation systems optimizes energy use, while low-VOC materials and improved ventilation systems enhance indoor air quality. Retrofitting with water-efficient systems also helps conserve resources. Adaptive reuse and the circular economy Adaptive reuse aligns seamlessly with circular economy principles, which aim to minimize waste and keep resources in circulation. By extending the life of buildings, adaptive reuse preserves valuable materials and reduces the need for new construction. It also helps close material loops by reusing and recycling materials like salvaged wood or brick during renovation. This approach enhances resource efficiency by limiting the extraction of new materials while incorporating energy-saving upgrades to improve operational performance. It also reduces landfill waste by preventing demolition and keeping materials in use longer. Best practices for successful adaptive reuse projects Community engagement boosts local support by involving residents early in a project. Key considerations for adaptive reuse projects include: Project planning Successful adaptive reuse projects require careful planning, collaboration, and community engagement. Planning involves evaluating the building’s structure, zoning laws, and historical significance while budgeting for surprises like structural damage. Setting sustainability goals such as energy upgrades or LEED certification early on guides the project’s direction. Collaboration Collaboration is vital for adaptive reuse projects, which require architects, engineers, and sustainability experts to work together efficiently. Digital tools such as BIM and Autodesk Docsstreamline coordination and keep everyone aligned, reducing costly delays. Community engagement Community engagement ensures local support by involving residents early, highlighting benefits like new housing or public spaces and addressing concerns transparently. Partnering with local organizations strengthens ties and helps navigate challenges. These strategies ensure smoother and more successful adaptive reuse projects. Future outlook on adaptive reuse architecture Urban planners are developing mixed-use developments that house residential, commercial, and recreational spaces. Urban planning is evolving to meet sustainability goals, adapt to changing space needs, and optimize existing infrastructure. Here are the key trends shaping the future: 1. Office-to-residential conversions With the rise of remote work, many cities are repurposing vacant office buildings into residential spaces. This addresses housing shortages while revitalizing urban areas. Cities like New York and London are updating policies to support these conversions. 2. Mixed-use developments Urban planners are prioritizing mixed-use developments that blend residential, commercial, and recreational spaces. This trend promotes walkability, reduces commute times, and creates vibrant, community-centered neighborhoods. 3. Government policies and incentives Governments are supporting adaptive reuse with tax credits, grants, and zoning changes. Cities are adjusting building codes to allow conversions and incentivizing energy-efficient retrofits. Programs such as the US Historic Tax Credit and Europe’s Green Deal encourage sustainable development. 4.

It is sometimes assumed that Building Information Modeling (BIM) is only useful in the vertical construction space. But the ‘building’ in BIM is misleading. Civil engineering and construction firms are increasingly adopting BIM processes and tools to improve efficiency, eliminate waste, and improve the outcomes of all kinds of infrastructure projects.  Keep reading to learn how civil construction professionals are now using BIM to deliver projects digitally. 7 ways civil engineers and contractors can now use BIM 1. Reduce data prep time Easily sharing design information with field teams and fleets has been a game-changer for Duna Aszfalt Zrt, one of Hungary’s biggest local civil contractors. “Because we have a 3D picture from 83 site designs of everything in the project, we can produce the machine control data in a very efficient way. I assume we spare about 75% of the time compared to earlier when it comes to producing machine control data,” reports Beatrix Szabo, BIM Manager. Because infrastructure projects are usually lengthier than building projects, and often require data from many different sources, civil BIM design software supports easier extraction of data than the traditional project delivery method of using piles of drawings or having to create a digital model from those drawings by hand.  2. Track and clarify project progress Using BIM sets a project up for a controlled, direct data flow between office and field, and design and construction. For example, survey engineers at PORR use WorksManager (Trimble’s design management and model versioning tool) to provide machine operators any updates to the model in real-time. As the machines move around the site, they create data of the surfaces they produce — which can be used in Quadri (Trimble’s civil BIM collaboration software). This provides PORR with the ability to know exactly what has been done, where it has been done, and by whom every day. It is easy for their BIM coordinator to produce volume calculations and get a good picture of how any changes will affect the project. 3. Organize and align project data One of the most important elements of working in BIM processes is using a common shared model. This serves as the single source of truth for all stakeholders on a project: Agencies, engineers, contractors, surveyors, machines, owners and other technologists all work off of one model. This helps teams eliminate data duplication across systems, catch issues before they stop production, enforce modeling and work standards, and simplifies planning. “When we are building a road foundation, where drainage is coming, we can combine design models with ground survey data in the same view, and quickly find out whether quarrying will be required or not,” says Heikki Lehkonen, BIM specialist at Skanska Infra. “I believe the shared database is an essential way to improve overall productivity and efficiency,” he concludes.  4. Get more accurate quantity takeoffs — faster Making quantity takeoffs digital through the use of BIM technology eliminates the need to scale information off drawings and photographs, or from a site that has not been prepped or clearly marked by surveyors.  The traditional quantity take off process involves manually selecting individual elements from 2D drawings, using software to automatically determine the dimensions for take-off, and then inputting the quantities into the quantity take off list. For estimators working in infrastructure, that often involves scaling information off drawings and photographs, or trying to collect information from a site that has not been prepped or clearly marked by surveyors. But BIM tools like Trimble Business Center eliminate the need for such manual work. They use advanced data and calculations to keep quantity estimating and processing highly accurate and to create integrated models that provide GNSS data. With rising construction costs, it is crucial for engineering and construction firms to make the most accurate cost estimates possible. Which all starts with precise, digital quantity takeoffs.  5. Save time during design revisions Ingi Gudmundsson, BIM engineer for Spotland, was looking to improve modeling capabilities on a complex development project that included the establishment of a wetland signalized junction, roundabouts, bridges, path connections, connections to a climate and environment center as well as recycling and treatment plans, conversion of an existing bike path, developing sewerage and drainage, and the planting and digging of ponds and streams. Gudmundsson explains that previously intersection modeling was a major challenge. “Where you have a cross-section on the main road, and then you have a different cross-section on the secondary road, it’s often problematic to make the models meet and fit with each other.” The surveyor and designer did their best to roughly line up the models but it was often left to the operator to freestyle intersections.  Now, Gudmundsson is able to use functionality within Trimble Business Center (a takeoff and site modeling tool) that allows him to select various properties for each road leg of an intersection and apply those directly to the model. Each connection can be adjusted manually or loaded from a template. He can also change the lane width and slope, as well as shoulder width and shoulder slopes. Once one road leg is set, Gudmundsson can copy the properties and place them into each other leg. He can also change the incoming and outgoing radii and quickly add turn lanes, curb heights, and walking paths. Gudmundsson estimates he saves at least 4 hours for every design revision on a medium-sized project site with five to 10 machines.  6. Coordinate utilities on complex projects The ability to track and share accurate onsite information across the team means less work for everyone involved. With reduced manual data management and eliminated redundancies, project coordination can run smoothly.  Recently, Norconsult used BIM to improve efficiencies on a large collaboration project. Norconsult was responsible for the entire infrastructure in the area — not only streets, roads, water and sewer, landscape and stormwater handling, but also the coordination of the garbage vacuum system, district heating, fibers and lighting. Even the technical coordination for all existing utility lines that lie in the ground was part of their mission. “We design the roads and water and sewer with Novapoint [Trimble’s civil BIM design software], and then coordinate and present all the discipline data in Quadri [Trimble’s civil BIM collaboration solution]. In addition, we do a lot of utility coordination between different utility networks and existing infrastructure, where we get good use of the collision control capability in Quadri, says Alexander Svensson, BIM project manager for Norconsult. 7. Fix problems in the office instead of in the field Changes on an infrastructure project are inevitable. But avoidable errors and mistakes that impact deadlines and budget can feel especially painful. Many civil firms use BIM technologies to minimize ‘working blind’ and uncover challenges before construction even begins. As Martin Karlsson, road engineer for Norconsultant, explains about using Civil 3D and Quadri for modeling and collaboration, “We now see exactly what we are doing and get a far better possibility to design what we are aiming for. We get continuous quality control of the design. We see immediately if our design collides with something else, if a manhole is placed wrong, or if a lighting post is strangely positioned. In addition, you can retrieve all possible data from the model, completely free.” Noroconsultant even brings BIM models into client meetings for easier coordination. They have been able to minimize mistakes and design conflicts, as well as reduce construction costs by doing this.  “You are always confident that you are working with up-to-date data. This minimizes the risk of using incorrect data and ensures that everything becomes as accurate as possible,” summarizes Alexander Svensson, road engineer at Norconsult. Even though the United States lags in BIM adoption compared to other countries, many industry associations, federal agencies, and state DOTs are adopting digital delivery processes. The American Association of State Highway and Transportation Officials (AASHTO), along with 17 state DOTs, are working to standardize BIM for bridges and structures, with the Industry Foundation Classes (IFC) scheduled for release in 2021. As more agencies see the value of BIM models, digital as-builts and other digital building techniques, and infrastructure projects become more complex and regulated, savvy civil engineers and contractors are getting in front of these shifts by proactively working to improve collaboration and constructability using BIM.   Article from: www.tekla.com

The Aimeé Césaire Airport extension project aims to increase its capacity to 2.5 million passengers, while meeting current safety and traffic flow standards. It includes the extension of the passenger terminal, the creation of a regional terminal, and the enlargement of the baggage control systems building. Designed by ADP in the 1990s, the building required both technical and symbolic transformation. General Project Overview The airport extension is based on an architectural approach that respects the existing structure while also aiming for better contextual integration. The initial building, designed to allow for future evolution, now sees its expansion potential fully activated. However, beyond mere continuity, the designers undertake a fresh reflection by fully integrating the geographical, cultural, and historical reality of Martinique, which was absent from the original project. The architectural approach deeply reconfigures the functional organization of the site. The linear paths of the original design are abandoned in favor of a loop organization that optimizes passenger and baggage circuits, increases the areas for security checks, check-in counters, and sorting systems. This new configuration provides a smoother and more coherent reading of the spaces, while giving back the central large hall a true spatial and symbolic identity. The intervention also introduces a strong gesture: a monumental red sphere, evoking Mount Pelée, dear to Aimé Césaire, becomes an iconic visual symbol, visible from both the ground and the sky. It embodies the imagination of the place and connects the project to the poetic and territorial memory of the island. Technical Challenges and Modeling The extension project faces numerous technical constraints due to the articulation between new structures and the existing building, as well as the extreme seismic context in which it is situated. Two major areas have been treated with particular attention: the East extension, which is a new building but immediately adjacent to the existing terminal, and the elevation of part of the original building, planned since the initial design in the 1990s but not realized until now. For these two interventions, detailed structural models have been developed. The geometry of the framework was generated from wireframe files from the architectural models, accurately converted into elements usable by engineering tools. Each structural sub-assembly was analyzed using an iterative dynamic approach, progressively refining the support stiffnesses according to the structural responses obtained. This method proved indispensable for achieving satisfactory convergence, especially in a context where the site is classified in seismic zone 5, in importance category IV, and rests on a class D soil. Furthermore, the very nature of the facility requires large and unobstructed interior spaces, which significantly constrained the position of stabilization elements. Their integration thus had to meet a dual requirement of mechanical performance and functional usability. Due to the large size of the structure and the high number of modeled structural elements, computation times became a critical factor. Managing this complexity required fine-tuning of numerical simulations, as well as structuring the models through families of elements to optimize computer processing. In the existing building, some areas are braced using cables functioning in pure tension. Their verification in the context of the new extensions required the implementation of nonlinear calculations to ensure their behavior under modified seismic conditions. Finally, the overall verification of the existing structure's strength after construction works demanded several models that incorporated regulatory developments since the original construction. These models allowed for encompassing a wide range of conditions: variation of response spectra, adjustment of material behavior coefficients for steel and concrete, recalculation of deep foundations. This comprehensive approach resulted in a rigorous and regulation-compliant evaluation of the project. Calculation Tools The RFEM software was used for modeling and calculation of the entire project. It enabled precise handling of the building's geometric complexity, interactions between new and existing structures, as well as the constraints related to the site's high seismicity, classified in zone 5. Several additional modules were used in a targeted manner. The RF-DYNAM Pro module was used for modal analyses and seismic calculations according to Eurocode 8, with a fine definition of response spectra tailored to the local characteristics. The design of the steel structures was carried out using RF-STEEL EC3, while reinforced concrete elements, such as walls, slabs, and others, were verified with RF-CONCRETE. The organization of the model by zones, the use of families of structural elements, and mesh optimization allowed us to control calculation times without compromising precision or regulatory compliance of the results. Conclusion The Aimé Césaire Airport extension project embodies an engineering and architectural challenge at the crossroads of functional, technical, and cultural issues. This large-scale project, conducted in a constrained environment, demonstrates the possibility of reconciling operational continuity, constructive innovation, and territorial integration, to make the airport a sustainable, efficient, and symbolically strong facility.

Say goodbye to time-consuming locomotion work and hello to more creative freedom with MotionMaker, now available in Maya. It’s a new Autodesk AI powered tool that lets you guide your character’s motion with just a few keyframes or a simple motion path and iterate until it feels just right. We spoke with Evan Atherton, senior principal research scientist at Autodesk and one of MotionMaker’s creators, to explore the tool’s origins and capabilities, time savings for animators, and how Autodesk is thinking about AI in animation.  https://youtu.be/2eUUVcMD1hg Q: Evan, great to talk with you. To start, what’s your background and how did you get into animation?  Evan: That’s a real softball! My name is Evan Atherton and I’m a Senior Principal Research Scientist on the Autodesk Research team, and a mechanical engineer by training. I did my undergrad and master’s at UC Berkeley, and during that time took a course called “Animation for Mechanical Engineers.” It taught us how to use Autodesk tools to animate complex mechanical systems to better communicate our ideas. That class really sparked my interest in animation and eventually filmmaking and visual effects too. At Autodesk, the longest stretch of my time in research was on the robotics team, where we worked on making industrial robots more accessible for design workflows. I got especially interested in how creatives could use them. I even built a Maya plugin to animate robot arms, which pulled me deeper into Maya, rigging, and animation. That’s when my love for this stuff really solidified. Q: Today, we introduced MotionMaker in Maya. Give us the elevator pitch. What is MotionMaker?  Evan: MotionMaker is a new animation system that lets artists direct characters more like they would in a mocap studio, but virtually, inside Maya. You can give high-level instructions, like telling a character to walk, jump, or sit, and guide them through the scene by setting key targets or paths. It’s part of the animation editor toolset in Maya, with a dedicated MotionMaker Editor. That’s where you manage characters, drive them with MotionMaker, and access all the related features. The goal is to make character animation feel more intuitive like giving stage directions to a digital actor. It gives animators time back, not to crank out more shots, but to explore, experiment, and really craft the perfect performance. Q: Take us under the hood. What AI models are powering the tool? Evan: At the core is a machine learning model we describe as an autoregressive motion generator. It’s built from multiple neural networks. The magic is really in how it fits into the larger workflow. We take motion data from Maya, pass it through the model, and it predicts the next pose, frame by frame, to create smooth, natural movement. A lot of the robustness comes not just from the model itself, but from how we handle that motion data going in and how we translate the results back onto the character in Maya. Set a few keyframes or a motion path, hit generate, and get motion to work off. Q: What kind of training data was used? Evan: We used motion capture data that we specifically collected for this tool. There are three core datasets: one from two dogs, combined into a single “wolf-style” model, and two from human performers, representing a basic male and a basic female motion style. The idea is to build each model around a specific actor’s performance, almost like capturing their unique motion personality. MotionMaker includes those three base styles, but that’s just the beginning. The system is designed to support additional styles as we go. Q: Who is MotionMaker designed for?   Evan: MotionMaker is designed for anyone in the animation pipeline, whether you’re working on layout, pre-vis, tech-vis, or even hero animation. My hope is that no matter where you are in the process, you can find a way to integrate it into your workflow. Q: I hear this started as an Autodesk Research project. What problem were you trying to solve?  Evan: At the time, there was a lot of exciting research, especially at SIGGRAPH, around motion control for character animation. I’d been following it closely and wanted to prove that this work could already be useful in real animation workflows. The goal was to take that foundational science and bring it into Maya in a way that fit naturally with the tools animators already use. I wanted to show how it could help artists move faster, especially with things like long locomotion sequences. Q: Have you had the chance to talk with other animators about it? What are they saying?  Evan: Yeah, we’ve talked to quite a few animators. One consistent piece of feedback is that they can see exactly where MotionMaker fits into their pipeline. For certain types of shots, it gets them 80% of the way there and then they can layer in their own touches to hit the final performance they want. That’s been really encouraging. The biggest question we get is, “Can I use my own data?” Animators know what they want, and they want tools that give them that control. So, we’ve spent a lot of time listening, not just to feature requests, but to the questions they ask. For example, a common concern was foot sliding. That led us to build a foot slide reduction tool. In early prototypes, we had only one path mode, which was “stay close to the path but look natural.” But animators wanted more precision, even if it meant sacrificing a bit of natural motion. So, we added multiple path modes to give them that control. It’s been a collaborative process. Q: What kind of time savings are we talking about?  Evan: One example I always come back to is a 10-second shot of a dog running, turning, and jumping. I asked our PM, who was an animation supervisor for years, how long that would’ve taken traditionally. His answer? “We probably wouldn’t have even bid on it. But if we did, maybe two weeks.” With MotionMaker, laying out that shot took about a minute. But to me, it’s not just about time savings, it’s about freedom to iterate. You can quickly try different jump timings, tweak a turn, or adjust the pacing of a scene. You could do 10 versions in an afternoon and see what feels right. It gives animators time back, not to crank out more shots, but to explore, experiment, and really craft the perfect performance. And the transitions, between gaits, turns, jumps, those come naturally from the model, no stitching mocap clips together. That’s a huge win. What we hope is that this tool can handle some of the stuff animators either don’t want to do or find time-consuming, so they can focus on what excites them creatively Lay out a shot that would take weeks in minutes. Q: How customizable is the output?  Evan: There are two layers to customization. First, the generation itself is pretty art directable. You can tweak the path mode, adjust the character’s facing direction, set when actions like jumps happen. All to guide the motion the way you want. Once the motion is generated, it’s baked to keys on the joints. From there, it behaves like mocap data. You can add animation layers, bake to a control rig, and use all your usual Maya tools to refine it. So, it’s fully integrated with standard animation workflows. Q: So MotionMaker isn’t just one-button magic. It comes with a full set of features. Can you walk us through some more key tools?  Evan: Yeah, honestly, the MotionMaker Editor itself is one of the biggest leaps forward from the original research prototype. That early version worked, but it wasn’t very user-friendly. You had to dig into the Attribute Editor and the Outliner to set keys, control timing, all of that. Now, it’s all visual and much more intuitive, more like a nonlinear editor. You can drop in actions like jumps, move or mute them, and adjust timing in a clean, visual interface. Then there are features like path modes, where you can quickly toggle between different behaviors and see what works best for your shot. One of my favorites is the auto speed ramp. In mocap, you’re limited by how fast a person or dog can physically move. But sometimes, for a shot or stylized moment, you need more. The speed ramp lets you push past those limits without it breaking. And even when it does start to break, that exaggerated motion can be great for superhero-style effects. MotionMaker comes with its own Editor because you’re not just generating motion, you’re directing it.  Q: If you could say one thing to fellow creatives about AI’s role in their work, what would it be?  Evan: This is a tough one, because the easy answer is just “AI is a tool.” But artists have been hearing that a lot, like, yeah, artists already know AI can be a tool. For me personally, it’s about making sure the creative people are involved in making these tools possible, like the artists who provide the data and the actors we work with. They all know what this is for and how it’s being used. It’s a trust thing. When we went out to capture motion data ourselves, it was important that everyone involved understood what the tool was for, that it was a machine learning model to help animators. On the user side, artists often ask where the data comes from, which is totally valid. So being transparent about how we captured the data and what the tool knows is key. I don’t see AI as a push-button, “here’s your hero animation” kind of thing. What we hope is that this tool can handle some of the stuff animators either don’t want to do or find time-consuming, so they can focus on what excites them creatively: crafting performances, adding intention, all that human stuff. Q: So, what’s next? Is this a finished tool or the start of something bigger?  Evan: By no means is it finished. For us, this is just the beginning. We’re really excited to see how artists use it, get their feedback, and let that guide where we go next. Like, what parts are they loving? What would make it even more useful for them? A big thing on our radar is letting them use their own data and curate their own stuff. That’s a priority. It’s an evolving process, and we can’t wait to see where it goes. Tamaskans in motion capture suits were hired in the development of MotionMaker. Q: Got a ‘did-you-know’ gem about MotionMaker that readers can flex in their next animation convo?  Evan: Oh, for sure! One of the coolest things we did was with dogs and honestly, it was one of the best days of my life. Did you know the breed we captured is called Tamaskans? They’re kind of rare, somewhere between a husky and a wolf. A lot of people mistake them for huskies, but they’re different. What’s really cool is these dogs are super well-trained. They do a ton of film and TV work, both in motion capture and on set. But their main gig is as therapy and service dogs, so they kind of moonlight as motion capture actors. Honestly, I couldn’t imagine better actors for our first model. Q: For those who want to dive deeper, where can they learn more?  Evan: I’ll be hosting a digital talk on MotionMaker on June 25 and June 26. Join the day and time that works best for you! In the meantime, you can check out our documentation to get started or reach out to me on LinkedIn. I really want to hear feedback. If you try it and feel like it doesn’t quite do what you expected, or it’s not fitting your workflow, I’m curious to know why and what would make it more useful for you.   Article From: www.autodesk.com

Currently, there are four main digital manufacturing trends that impact production workflows, workforce engagement, and operational flexibility. Below, we explore these trends and the Autodesk solutions supporting them. Trend 1: Intelligent automation is taking over routine operations The next phase of automation is deeply integrated with artificial intelligence, turning production environments into adaptive, decision-making systems. Instead of static programming, today’s factories are embedding machine learning models into their operation. This allows robotic systems to continuously improve based on live sensor data. Such AI-enabled automation unlocks dynamic scheduling, flexible production cells, and even predictive intervention before failures occur. To support this shift, Autodesk Fusion Operations provides real-time production tracking and manufacturing execution system (MES) capabilities, enabling manufacturers to unify planning and production. Fusion Operations collects live data from machines, workstations, and operators and turns it into actionable insights. By providing a detailed digital thread of production data, Fusion Operations gives factory leaders the clarity to optimize workflows and maintain throughput as automation becomes more complex. Trend 2: Digital twins for predictive and agile manufacturing Digital twin technology has matured into a non-negotiable capability for manufacturers seeking agility. By creating virtual models of physical systems, companies are simulating production outcomes, testing design changes, and forecasting maintenance needs before implementing changes on the shop floor. To add, the fusion of digital twins with IoT sensors means these models update in near-real time, reflecting live operational conditions. This is a game-changer for both high-volume and high-variability environments that demand flexibility and reliability. Autodesk Inventor helps operators create these accurate, simulation-ready digital models. Its advanced parametric design and mechanical simulation tools allow engineers to replicate geometry, motion, stress response, and dynamic behavior of assemblies. Inventor becomes part of the digital twin ecosystem when connected with downstream data tools or MES systems. This connection allows teams to virtually commission machines, test design iterations, and validate system-level interactions before physical deployment. For factories managing complex assemblies or bespoke production setups, Inventor accelerates the transition from static planning to digitally managed production. Trend 3: Sustainability and energy efficiency in digital manufacturing Manufacturers are facing growing pressure from governments and consumers to reduce environmental impact. Initiatives like low-emission operations, circular material use, and sustainable energy sources are becoming true business drivers. Factories are widely adopting strategies such as lightweighting, additive manufacturing, and material substitution to lower energy usage and carbon output. More importantly, sustainability is not only considered in operations, but in the design phase as well. Autodesk Fusion plays a pivotal role in enabling sustainability in design by integrating comprehensive tools that allow designers to assess and mitigate the environmental impact of their creations. Through the Manufacturing Sustainability Insights (MSI) feature, Fusion provides real-time calculations of the carbon footprint associated with manufacturing processes, from cradle to gate. This includes evaluating the effects of material choices, manufacturing methods, and geographical considerations. Fusion also has an extensive materials library so that designers can opt for eco-friendly options that reduce emissions and waste. By facilitating informed decisions on energy and material usage, Fusion helps designers create products that are not only innovative but also environmentally responsible, contributing to a more sustainable future in manufacturing. Trend 4: Workforce digitization and training With the rise of advanced technologies, skills development has grown from operating machinery to data interpretation, system monitoring, and cross-functional collaboration. Manufacturers need to invest in training platforms and digital documentation to onboard workers faster and empower them with intuitive, visual tools. As such, technologies like augmented reality, remote support systems, and standardized digital workflows are merging legacy knowledge and next-generation systems. Autodesk Vault supports the digital manufacturing transition. It manages and centralizes all product and process documentation in a secure, searchable environment. As factories become more reliant on digital workflows, employees are always working with the latest approved files and revisions. For onboarding and continuous training, Vault can be seen as a centralized system. Here internal knowledge and formal documentation coexist, allowing manufacturers to scale knowledge without losing quality or compliance. Supporting digital manufacturing with smarter tools Digital manufacturing is already embedded in the way factories operate, evolve, and compete. With the right digital tools, manufacturers can transition from reactive to proactive operations and achieve a more integrated, holistic approach.

As part of the modernization of the mountain transport infrastructure, the old "Jandry" cable car was replaced by a 3S cable car of the latest generation. The complex project required the construction of three new railway stations that combine technical performance with harmonious integration into the Alpine landscape. For this exceptional project, which was delivered at the end of 2024, the company carried out the structural analysis and design of the combined structures made of timber, metal, and concrete. Project Presentation The operation consisted of the construction of three new railway stations, located at 1,600 m (5,249 ft), 2,600 m (8,530 ft), and 3,200 m (10,499 ft) above sea level. The study and dimensioning of these structures were entrusted to GUSTAVE, who took charge of the structural design and analysis using RFEM. Each station has its own specific architectural and structural features, adapted to its environment and to the extreme conditions of the site. The valley station, located at a height of 1,600 m (1,967 ft), is designed with truss timber frames supported on concrete walls. The envelope is closed with cross-laminated timber panels of up to 20 m (66 ft) in height. At an altitude of 2,600 m (8,172 ft), the middle station consists of glulam beams supported by concrete walls with a CLT envelope to close the volume. Finally, the top station at an altitude of 3,200 m (10,499 ft) keeps the structural principle of the initial station, but with steel frames adapted to the extreme conditions of this altitude. In all three cases, the CLT panels are used as a support for a tiled cladding made of aluminum plates. This technical choice ensures both an outstanding aesthetic quality and reinforced protection against the effects of weather. Technical Data This project had to take into account many constraints, including extreme weather conditions with high snow and wind loads at high altitude. The logistics of the construction represented a major challenge, requiring complex transport and lifting of the structural elements in the mountainous area. Strict compliance with the planning was also a major challenge in order to ensure that the cable railway would be in operation on time. Finally, the architectural requirements imposed the harmonious integration of the structures into the Alpine landscape, while guaranteeing optimal sustainability against the effects of the weather. Structural Analysis Software The RFEM 5 program was an essential tool for the modeling and structural analysis. It enabled precise calculation of the forces and deformations under climatic and live loads, as well as an advanced analysis of timber, steel, and concrete elements in the application modules. The structural analysis of connections and of interaction between materials could be performed meticulously. On the other hand, the dynamic analysis was very important; it was managed using the RFEM modules for seismic analysis. Multiple analyses were performed to optimize the cross-sections to ensure maximum strength while limiting deformation and complying with the building standards. The replacement of the "Jandry" cable car was successful, both from a technical and an architectural point of view. This new combination structure is the most successful mountain railway in the mountain world. Overcoming the extraordinary technical and technological challenges of its design and construction was only made possible thanks to the full involvement of passionate men and women who rely on the most powerful tools, including RFEM. This project exemplifies the expertise and innovation utilized to meet the challenges of construction in an extreme environment.     Article from: www.dlubal.com

Ease of collaboration, detailed shop drawings, and parametric modeling entice more steel fabricators to choose detailers using Tekla Structures. As part of the construction process, it’s up to the steel detailer to provide steel fabricators with detailed and accurate fabrication information, often in the form of shop and layout drawings. Fabricators need these details to reduce flaws and increase construction accuracy. Still, when a project relies solely on physical shop drawings, there are typically multiple inefficiencies and setbacks throughout the workflow. Recently, more steel fabricators have started to realize the models they receive that have been created in Tekla Structures contain data with more precision and consistency, requiring less rework on their end. Rather than being forced to depend on physical drawings for information, a 3D model-based projection with fabrication drawings reduces the issues fabricators often experience regarding scheduling or redrawing. All project parties can inspect the model from any angle and monitor it on-site. Using the model throughout a fabrication workflow improves project management and ensures a seamless flow of information between all departments. Additionally, 3D modeling software allows the development of a detailed and information-rich model, offering better visualization and insight throughout the project. Shop and layout drawings are also fully integrated into the model, so any changes to the model are automatically applied to the drawings as well. This ensures drawings and other outputs always match the model, so everyone involved can communicate model changes and coordinate effectively with the 3D model as their single source of truth. "We require our detailers to supply drawings created in Tekla Structures because of accuracy and consistency. In addition, our production systems rely on the reports and data we receive with our drawing packages." - Ben Finnoe, President, Finnoe Design Currently, Tekla Structures leads the industry in 3D BIM modeling because users can quickly automate the shop drawing process, reducing human error and improving accuracy. Tekla Structures can generate six types of custom drawings for the user: single part drawings, per part, assembly drawings, general arrangement drawings, multi drawings and cast unit drawings. In addition, they can also easily produce fabrication drawings, erection drawings, reports, bill of materials and schedules from the model. Because of its flexibility, Tekla Structures can create a detailed 3D model for any steel structure and coordinate the design, fabrication, and site operations for an enhanced, more automated workflow. The information-rich models provide a powerful source of intelligent and well-organized information for steel fabricators, including data for CNC processing, material handling, and even robotic welding. "We are using 3D laser scanning technology at our job sites, and the ease of bringing point clouds into Tekla Structures and being able to model on top of actual field conditions is very important for us to fabricate our steel based on ever-changing field conditions."-Dave Litwin, Technology Manager, Bapko Metal 6 ways steel detailers are using Tekla Structures: To provide fabricators with real-time access to a parametric, digital model To generate detailed fabrication drawings with 3D visualizations from the model To interface with technologies like CNC, MIS, PLM, ERP, detailing software and nesting solutions To generate CNC data directly for the fabricator To avoid detailing errors in fabrication, minimizing the need for rework To Take advantage of intelligent interfaces that optimize the fabrication process "Having the Trimble Connect model that is easily exported from Tekla Structures and connected to PowerFab is crucial for planning and reviewing erectability issues in our Project Management, Production and Erection departments."- Dave Litwin, Technology Manager, Bapko Metal Tekla Structures is known in the construction industry as a powerful and flexible software because working with Tekla software has consistently been the most accurate, integrated way to manage detailing, fabrication, and erection. That’s why we’re seeing more and more steel fabricators choosing to work with detailers who use Tekla Structures for their projects.

IDEA StatiCa uses a material model for welds which allows for plasticity with a maximum plastic strain limit of 5%. Understandably, many questions arise regarding the use of this plasticity in welds in IDEA. Questions like: Is a plastic distribution in welds allowed and in accordance with the standard? Does the way in which welds are modeled in IDEA not lead lead to a resistance that is too high? How does IDEA deal with the requirements of Cl. 4.9 of EN 1993-1-8 which state that ductility of the welds should not be relied upon? How does IDEA deal with the requirement that welds should be sufficiently strong not to rupture before general yielding in the adjacent parent material? In this article we provide answers to these questions. Actual behavior of a weld It will be helpful to first consider the real behaviour of a weld. The real stress distribution or strain distribution in a fillet weld under various load combinations is however difficult to determine precisely. Moreover, the material properties in the parent material near the weld and in the weld itself cannot be said to be homogeneous. To gain insight in the failure behaviour of welds therefore, a large number of experimental tests have been carried out worldwide. Consider for example the following lap joint which is loaded in longitudinal direction. Similarly to bolted connections that are loaded in longitudinal direction, the stress distribution will not be uniform. Nevertheless, qualitatively one can indicate how the stress distribution would be. The highest stresses occur at the ends Figure 1 - Non-uniform distribution of shear stresses in a lap joint   When increasing the load further it appears that the weld does exhibit deformation capacity, and that local yielding can occur (Figure 2). Figure 2 - Non-uniform stress distribution of shear stresses with local yielding in a lap joint Eurocode method Different weld configurations and load combinations may lead to different stress distributions. A semi-empirical approach was chosen as a basis for the design calculation rules from the Eurocode. Instead of checking the failure mechanism at a micro scale, the welds as a whole are checked on a macroscale. A simplified failure model was assumed, based on plasticity. By calculating back to the experimental test results a failure criterion (weld formula) was determined. EN 1993-1-8 Cl. 4.5.3 describes two methods for the determination of the design resistance of fillet welds, the Directional method and the Simplified method. The Simplified method is a simplified method of the Directional method. In the Directional method, the forces that are transmitted by a unit length of weld are resolved into components parallel and transverse to the longitudinal axis of the weld and normal and transverse to the plane of its throat. The design value of the resistance of the weld shall be sufficient if the following equations are both satisfied: Where: σ⊥ the normal stress perpendicular to the throat τ⊥ the shear stress perpendicular to the axis of the weld τ || the shear stress parallel to the axis of the weld fu the nominal ultimate tensile strength of the weaker part joined βw the correlation factor depending on the tensile strength of parent material γM2 partial safety factor for bolts and welds = 1.25 In the weld calculation of statically loaded structures it is then allowed to assume a uniform stress distribution over the thickness and along the length of the weld. Here it is also implicitly assumed however that plastic strains can occur to make redistribution of stresses possible. The needed deformation capacity increases as the weld length increases. The ultimate strain is still considered limited however, thus in certain situations one will have to take into account an effective width beff, for example in a joint where a transverse plate (or beam flange) is welded to a supporting unstiffened flange of an I-profile (Figure 3). Figure 3 - Effective width of an unstiffened T-joint CBFEM method By contrast, in the CBFEM (Component Based Finite Element Model) approach that is used in IDEA StatiCa, a weld consists of multiple smaller elements next to each other. The weld thickness, position and orientation of the weld is taken into account. Stresses and strains in each element may vary from each other. Therefore, in the model a non-uniform stress distribution develops automatically which is more realistic than the idealised uniform stress distribution according to the codes (Figure 4). Figure 4 -Stresses in plates and welds in a welded beam to column connection IDEA The aim of the applied material model in IDEA is however still not to capture reality perfectly. Residual stresses or weld shrinkage are neglected. The material model with its plastic limit strain value is chosen such that the total resistance of the weld in an IDEA model matches well with the resistance according to the codes. To achieve this, IDEA StatiCa has carried out many validations. In the CBFEM book (written by prof. Frantisek Wald et al. of Czech Technical University in Prague) and in subsequent research, a large number of comparisons have been made between different types of welds calculated in IDEA and calculated according to the codes or welds loaded in experiments (see Figure 5). On our website many validation documents can be found on this topic - support center verifications Figure 5 - Shear stress - deformation diagrams from experiments by Kleiner (2018) compared to CBFEM This shows that the strain limit that is used leads to a safe total resistance of the weld which also matches well with the resistance calculated according to the relevant codes. This is the reason why a plastic redistribution in welds in the IDEA model is considered acceptable. Without plasticity in the welds, one could never come close to the resistance calculated by hand according to the codes. Additional requirements from EN 1993-1-8 art. 4.9 EN 1993-1-8 in Cl. 4.9(4)-(6) further states additional requirements for welds in joints. The idea behind these rules is that a joint should be prevented to fail without sufficient warning. Even if one can show that plastic strains can occur in welds, and that the weld is in principle sufficiently strong to resist the occurring forces which are determined in a general (static) calculation, it might still be the case that the occurring forces are larger than expected and could lead to failure of the joint as a whole without sufficient warning. This is because the total elongations in a weld may still be small in an absolute sense. Sufficient warning effect may then be obtained by designing the joint in such a way that the connected plate can yield before the weld ruptures. This can be achieved by applying a minimum weld thickness to plate thickness ratio. Therefore, IDEA StatiCa includes detailing checks to verify whether a weld in the model has a sufficient weld thickness for a given plate thickness. The specific rule that IDEA has implemented for this is based on Cl. 6.9(4) of the concept version of the upcoming new Eurocode (FprEN 1993-1-8:2023(E)) which states that to satisfy sufficient ductility, the weld must be designed in such a way that its resistance is at least equal to: 1.1 fy/fu times the design resistance of the weakest connected plate but need not be more than the design resistance of the weakest connected plate Assuming the following standard T-joint example (Figure 6): Figure 6 - T-joint with normal force acting on the connected plate equal to the yield force of the plate   where the magnitude of Fs,d is chosen such that Fs,d = fy,plate ∙ t ∙ l, This leads to the derivation of the following formula used for the detailing check in IDEA for double-sided fillet welds: Where: a weld thickness t thickness of the connected plate fy,plate yield strength of the connected plate fu,plate tensile strength of the connected plate fu,weld tensile strength of the weld βw correlation factor depending on the tensile strength of the parent material γM2 partial safety factor for bolts and welds = 1.25 γM0 partial safety factor for plate resistance = 1.0 For the following standard steel grades this leads to the following minimum weld thickness – plate thickness ratios (Table 1). Table 1 - Minimum weld thickness for ductility Steel grade 1.1 ∙ fy,plate/fu,plate Minimum weld thickness S235 0.72 a ≥ 0.33 ∙ t S275 0.70 a ≥ 0.34 ∙ t S355 0.80 a ≥ 0.46 ∙ t For single-sided fillet welds the derived value must be multiplied by 2. The user of IDEA will receive a warning when the applied weld thickness does not satisfy the minimum value (Figure 7). The user shall also receive an error message when welds are applied with throat thickness smaller than 3.0 mm which is not allowed according to EN 1993-1-8 Cl. 4.5.2(2). Figure 7 - Warning when applying too small weld thickness in IDEA Nevertheless, there might be situations where one can argue that it is not necessary to satisfy the minimum weld thickness requirement for ductility purposes. For example, welds of a column base plate connection which mainly transmit compression forces. Or if one could show that some other part in the global structure exists that would fail with sufficient warning anyway. The program should always be considered as a tool, it is up to the engineer to use his or her engineering judgement to make an informed decision about the final design.   Article from: www.ideastatica.com

In the heart of Vietnam's Phu Quoc Island, the Sea Shell Aquarium stands out as a structural engineering marvel, showcasing a unique turtle-shaped design and housing a diverse array of marine life, including 1,000 jellyfish, 200 penguins, and numerous rare fish species. Spanning 15,000 square meters across three floors, this complex structure integrates challenging design elements with advanced engineering techniques. About the project Designed by Arup, it was a challenging task to realize this unique form and complex geometry of the aquarium within a tight deadline. The scope of work covered structural, geotechnical, MEP, and fire engineering. As many iterations and analyses were required, this project would not have been possible without innovative structural software. This included Rhino with Grasshopper, GSA, and IDEA StatiCa. With the BIM links facilitating the workflow, the flow of information was seamless and saved a lot of time and effort. Engineering challenges The conventional approach to creating a free-form outer surface is using beam and column construction supported by secondary non-structural frames. However, the size and positioning of the tanks made this approach challenging. Instead, a more complex long-span arrangement was used for the roof structure, which allowed for simultaneous construction of the outer façade and internal systems of the structure. The initial structural scheme involved a roof with a series of radial warren trusses and two rings of circumferential transfer truss systems. The whole roof rested on top of the concrete columns, providing a defined and efficient load path. After many iterations and adjustments (e.g., roof design, column layout, number of columns, boundary of roof, height of trusses, type of joint, bracing layout, etc.), the structure was finalized. Solutions and results Before IDEA StatiCa, the team would have had to have designed the connection using Excel. IDEA StatiCa Connection enabled the team to model all bolted and welded connections quickly and safely. Advanced analyses including buckling, stiffness analysis, design resistance, and seismic were completed with minimal effort. Thanks to IDEA StatiCa’s BIM link to GSA, the model modeled in GSA was exported to IDEA StatiCa, including internal forces, member sections and geometry data. This allowed the team to minimize errors and repetitive work to save time for other crucial tasks. About Arup ARUP is a multinational professional services firm headquartered in London that provides engineering, design, planning, project management and consulting services for all aspects of the built environment. With nearly 20,000 employees, it is among the largest and most prestigious of engineering consultancies in the UK.   Article from: www.ideastatica.com
