Tekla News for Building & Construction, Summer 2015
Fluid, organic shapes made of steel in the middle of a 600-year old city district? An airport with models prepared with a lifetime expectancy of 50 years so the information can be used for renovations in the 2060s? Wearing a device to see a holographic image mixed with the existing structure of a building? Unlikely? No, it is the summer issue of Tekla News.

Dongdaemun Design Plaza (DDP) is the latest architectural icon of Seoul, the capital of South Korea. Designed by the renowned architect Zaha Hadid, the multipurpose cultural centre is located in the 600-year-old Dongdaemun district. With its futuristic fluid lines, the 86,574 sq m DDP is the world’s largest free-form building. DDP is pillar-free internally while the roof is supported using mega-truss technology.
The general contractor Samsung C&T faced a host of challenges because of the tight deadlines and budget – and the geometry. During the construction process, they saw that the building could not be realised using 2D technology. The company decided to deploy BIM to complete this project, and DDP became the first building where Samsung C&T used BIM for every aspect, ranging from civil groundwork, structures and MEP to interior finishing.
However, working on the 2D drawings and the 3D models separately during design caused some inconsistencies in the data. Samsung C&T turned to Tekla to resolve the discrepancy and achieved a virtually error-free state in just three months. And once they got started with BIM, the team going: They extracted information for production planning and Bills of Materials, placed the cranes and created erection drawings with Tekla.
Tekla has been renewing its online services, and as a result we have opened the new Tekla Discussion Forum, Warehouse, User Assistance and Downloads. These services now contain the information, downloadable files and other content of the old Extranet, which will close at the end of June.
One reminder: to utilise Tekla’s online services, you need a Tekla account. If you do not have Tekla account yet, please register.
Tedds 2015, the latest version of the engineering software for automating repetitive civil and structural calculations, streamlines calculations and increases productivity. Using Tedds, structural engineers can now utilise a fully automated library of civil and structural calculations to British Standard and Eurocode as well as Australian, Canadian and US codes.
The new features of Tedds 2015 allow, intuitive designs of steel beams to Eurocode, simultaneous reviews of multiple loading configurations, and an easier way to combine multiple calculations in a single report. The transparency of the calculations strengthens confidence in design results and helps engineers create professional and consistent project documents, including notes and sketches. Added after Trimble’s acquisition of CSC, Tedds is an integral part of the Tekla portfolio of software for the architectural, engineering and construction industry.
In precast fabrication, inefficiency in project coordination and monitoring progress can lead to excessive waste and costly surprises in different stages of the process. As the progress of the project can be visualised with a Tekla model, every project member easily to understand the situation and helps them plan their work.
Previously, defining statuses in UDA tab pages of Tekla Structures and creating visualization settings has been laborious and prone to errors. To make using this valuable element in model-based workflow more user-friendly, we have now introduced a new application called StatusTool.
StatusTool is easy to use and understand and makes defining and visualising the status of model objects much more efficient. StatusTool helps people who work in design, production and on site better monitor and coordinate the progress.
Both manufacturing and welding are processes that benefit from accurate design information, such as that in the Tekla models. The welding and production automation producer PEMA now provides software solutions that link the design data with the production equipment on the shop floor.
Utilising existing digital data avoids human errors that can otherwise happen when the data is manually entered in to the production-controlling software. It also lets the manufacturer control the production schedules and easily create reports.
With the Tekla-PEMA integration, manufacturing even one-of-a-kind project components with the highest automation level is possible, saving time and improving quality, especially for offshore and civil construction fabricators and designers.
Trimble and Microsoft have started collaboration to bring Microsoft HoloLens, the wearable holographic technology, to construction. Microsoft HoloLens provides a mixed-reality experience for a range of commercial and consumer applications. Trimble and Microsoft are working to develop a new generation of solutions to improve quality, transparency and collaboration across the Design-Build-Operate lifecycle of buildings.
For the AEC market, the HoloLens device can extend interaction with 3D models beyond the confines of a 2D computer screen, which means creating new ways for teams to visualise, share ideas and manage change. Trimble's initial research focuses on the integration of HoloLens with SketchUp and Trimble Connect, the collaboration environment for design, engineering and construction projects.
A renovation project with over 100 contractors can be a little challenging. Gardermoen Terminal 2 is such a project taking place at a functioning international airport in Oslo, Norway. In this case, the priorities of the main structural engineer Aas-Jakobsen include passenger safety and airport security as well as regular day to day operations.
To Aas-Jakobsen, information-rich building information models have been a question of survival on the project. Avinor, the airport company and end client, demanded modelling from the contractors. The BIM team has over 100 reference models, including HVAC, electricity and baggage handling.
Using Tekla models Aas-Jakobsen can visualise reinforcement, extract documentation and create schedules. Additionally, the model information has been utilised for rebar production by connecting to an external application using Tekla Open API.
Because the airport will need regular renovations, these models will be used in the future to provide accurate information about the existing structures. Building information will be an asset for the airport company Avinor long after Aas-Jakobsen has moved on to new projects.
The very first customer training groups of Tekla Structural Designer's hands-on workshop in Singapore and Malaysia seem to have been fun events and have been very popular too!
