Tekla News, Autumn 2017
Digitalization of the construction industry is here – that is, everywhere. The processes becoming increasingly digital around the world. In this issue of Tekla News, we meet construction projects and companies from New Zealand, Laos, Germany, Vietnam and Finland, all wanting to take advantage of the current development.
In addition to processes, also digital tools are developing: Meet the new versions of Tekla solutions!

The new versions of Tekla Structures, Structural Designer and Tedds are now available for download, all introducing beneficial improvements and fixes.
Tekla Structures 2017i
The new version includes improvements and fixes for example in drawings, collaboration and modeling complex geometries or reinforcement.
As a practical example of what the new version has to offer is modeling structures like spiral shaped stairs, which can become quick and easy with the new Spiral Beam. Working with steel bent plates is now easier, while Precast Concrete Floor and Wall Layout and the flexible, intelligent Tekla method for modeling and modifying reinforcement have been improved. Creating more complete drawings becomes faster, and DWG export functionality is more efficient.
In addition, there are new tools on top of Trimble’s collaboration platform, Trimble Connect, for model and cloud-based supply chain management between Tekla Structures and Trimble Connect.
Tekla Structural Designer 2017i
The new version of the analysis and design tool for structural engineers allows more productive modeling, includes more design codes and offers improved BIM integration. This is reflected, for example, in improvements that allow spending less time doing manual calculation work outside the software workflow, and data that passes to Tekla Structures and Revit more smoothly.
Tekla Tedds 2017
The new improvements in the software for automating repetitive structural calculations boost your productivity. For example, Batch design for any Tekla Tedds calculation is now possible, and what is more, there is a wealth of new and improved calculations.
When retailer The Warehouse wanted to expand its already-massive distribution center in Rolleston, New Zealand, Holmes Consulting employed an innovative solution – and won Tekla Global BIM Awards industrial project category for their work.
The facility needed to remain fully productive throughout construction, and adding to the challenge, the existing building had shifted during an earthquake.
“First, we needed to make sure the building was structurally sound and still positioned as indicated in our 2D models,” says Business Manager Jeff Matthews at Holmes Consulting. “We contracted surveyors to scan the end frame of the building using 3D laser scanners.”
Holmes used laser scanning data to generate point cloud models, and then created a 3D model in Tekla Structures so the old and new structures could integrate smoothly. The point cloud models generated showed definite movement - not a lot, but enough to create unpleasant surprises during construction and cause costly delays. “We integrated this critical information into the documentation right from the start,” Matthews says. “It meant we didn’t need to modify key connections on site during construction.”
The Holmes team produced all documentation for the project, including general arrangement (GA) drawings, from the Tekla model, and create a materials schedule. “Our Tekla model gave us certainty of materials costs and time on site,” says Matthews.
“Using point cloud analysis saved us an enormous amount of time. We didn’t have to convert our original 2D model to 3D,” concludes Matthews. After completion of the project, The Warehouse plans to utilize the accurate model of the building for its maintenance.
At Trimble, we seek to truly understand the construction industry. This September our annual precast study took about thirty precast construction professionals from Asia and the Central America to a road trip, introducing fabrication facilities and construction sites around Southern Finland, not forgetting the digital tools.
Interest in precast construction is growing. For Mr. An Nguyen Van, Vice General Director of the Vietnamese Hoa Binh, precast concrete is not at the moment very commonly used in construction, but because precast construction is faster and efficient, it will grow in importance as a construction material. His company seeks expertize in precast construction and aims to becoming a frontrunner.
Nam Ngiep 1 is a 290-megawatt hydropower project in Laos, comprising of two dams and power stations, of which the first is 167 m high and 530 m long. It is designed to harness the energy potential of the lower part of the Ngiep River, a tributary of the Mekong River that flows through Laos and Thailand along the borders.
The main power station, constructed by Song Da 5 JSC, is the key component of the project. It is a reinforced concrete building housing two turbines.
Driven by tight schedules, the team decided not to use 2D drawings. They adopted a BIM process instead, using Trimble’s software such as Tekla Structures and SketchUp. SketchUp proved valuable in the initial outline and conceptual design phases. Tekla Structures was the team’s choice for tasks where a higher Level of Development (LOD) was required, for example modeling accurately the complex concrete and rebar structures, and to ensure constructibility and error-free information.
The detailed model helped detecting clashes and potential problems, and fixing the errors on time for the process models. Using the constructible model, reinforcement quantities could be easily and accurately extracted to an Excel file for the general contractor.
Tekla Structures' collaborative features allow multiple users to work simultaneously on the same model, which significantly improved coordination between the team members. Engineers could create, update and access all of the essential information in the models, including accurate information about materials, quantities and construction progress.
“By using Tekla, we can provide 3D models with a high LOD and accuracy, and avoid errors or defects from occurring later during the construction phase,” says Bui Chi Giang, Technical Manager of Song Da 5 JSC.
Donges SteelTec is one of Germany's leading steel construction companies. They are currently working on the launch base and tower for the European Space Agency’s launch vehicle Ariane 6, whose first flight is planned for 2020.
The company chose Tekla Structures as its primary and strategic tool for model-based planning and execution in steel construction when they were looking for a tool for demanding projects. Ariane launch base 6 is already the second demanding project where Donges SteelTec takes advantage of open BIM and Tekla Structures.
Collaboration and smooth exchange of information
"It was important for us to choose a tool that is the standard in steel construction and allows for good collaboration and a smooth exchange of information with project partners," explains Thorsten Nicolay, Technical Director at Donges SteelTec.
Tekla Structures interfaces with other industry solutions for planning and fabrication. It follows an open BIM approach, facilitating the free exchange of models and building data. Donges SteelTec plans to expand the use of Tekla software, and using it in BIM workflows plays a major role.
"We know Trimble is very active in this area, and we want to identify new ways to make the best use of the software," Thorsten Nicolay says.
