Building & Construction Summer 2013 Newsletter
In this issue of Tekla News we meet the Tekla BIMja and follow his journey around the world. Are you a Tekla BIMja? Get ready for the ultimate meeting of the BIMjas. Elevate - The Tekla North America's User Meeting has just been announced and will take place on April 30th - May 2nd, 2014 in San Antonio, Texas. Stay tuned for much more information to come.
Also in this issue, we take a quick look at two interesting and totally different construction projects: Vienna Central Railway Station in Austria, and Panorama shopping center in Estonia. The one thing they have in common is the need for information flow – between model and measuring device, or two software solutions. It is obvious that open approach to BIM and collaboration is crucial for the flow.

BIMja: [bim-jah] A Tekla software user who has become highly efficient, precise, and cutting edge in modeling and detailing of structures and building projects.
Tekla and Intergraph® have developed an enhanced structural data exchange link between SmartPlant® 3D and SmartMarine® 3D and Tekla Structures to provide better support for users’ workflows and reduce modeling time. It replaces the previous CIS/2 import/export functionality.
Thanks to the OPEN BIM approach, this Building Information Model exchange allows better data transfer. Users can now pass additional objects with extended properties and visualize improved change management functionality.
Supportive to Tekla’s multi-material functionality, the new exchange works with structural steel and concrete objects together and supports the transfer of traffic items like stairs, handrails and ladders.
For a more in-depth information on the link, we recommend the webinar Better BIM exchange between Intergraph Smart 3D and Tekla Structures

American Institute of Steel Construction (AISC) has adopted the IFC file format at the core of its interoperability strategy. Demand for automation in steel fabrication has increased, which creates new challenges for the information quality and flow. In the past, the CNC automation was relying on DSTV format to fabricate individual steel parts. As the focus has moved to increasing the productivity in the laborious assembly phase, DSTV standard can struggle to fulfill the demands.
The latest NASCC, the steel conference, in April examined the nuances of IFC files, dispelling some myths and perceptions along the way, and the progress toward actual IFC exchanges in the structural steel industry.
According to AISC, IFC (Industry Foundation Classes) is an open, neutral and standardized specification for Building Information Models which offers a promise unmatched by previous standards: a single standard to use across various trades and professions in the industry. Until now the IFC based workflows have been more common in design, but IFC would bring the whole steel fabrication industry into the BIM workflow.
The idea of expanding IFC use into steel fabrication to ease automation originated from Tekla. To drive the automation and new technologies in to use, Tekla, HGG and FICEP decided to put all the knowledge gained from the individual development works done to define and create a new standard for the steel fabrication industry to meet the current and future demands. HGG, specializing in 3D profiling, decided to work together with Tekla to create a direct information flow from the Tekla models to the HGG machines for 3D pipe beveling/profiling. This new flow includes more structured and richer information. FICEP utilized Tekla Open API™ to develop an application and a file format taken directly from the Tekla models. This allowed them develop processes like scribing.
As AISC revised their strategy regarding the information standards it became an obvious choice to work together on the same goal. AISC and Georgia Tech made it possible to have a neutral party (Georgia Tech) to do the official definition of the standard (Model View Definition, MVD) based on the vendors’ requirements.
The first trains have arrived to the new Vienna Central Railway Station in the Austrian capital – under a roof build with Trimble Total Station and Tekla software. The partially transparent, architecturally stunning roof gives arriving passengers the first glimpse of Vienna.
Making the roof was quite a challenge: It includes 254,000 screws, 54,100 frames and 271,100 metal sheets but no horizontally arranged components.
The Austrian steel specialist Unger Steel Group used both Tekla Structures software and Trimble Total Station for the creation of complex, hard to assemble structure in a very advanced way to model, produce and assemble the 14 unique diamond trusses.
Modeling for production and logistics
Unger is an experienced Tekla user and utilizes the software not only for design and detailing but also for automated production in workshop. For the Vienna Central Station, the Unger team modeled and detailed the main structure and substructures like cable channels, extracted data and drawings for production and assembly, and simulated welding sequences of the complex components.
For running the assembly smoothly, the team created transport lists and surveys directly from the model because timing and having the right material at the right place were crucial. They also used the model to control production and assembly sequence.
Measuring and modeling for assembly
For assembling the 14 complex trusses, Unger used Trimble Total Station with Tekla Structures. The team had to assemble the roof components while these hung from a crane at height of 15 meters, and they needed exact position information for lifting and fitting. To avoid any inaccuracies, the team continuously measured the structure, downloaded the measurements into the Tekla model and after this planned and manufactured the connection parts.
Combining the potential of Tekla Structures and Trimble Total Station not only allowed Unger complete the job successfully. They also saved on expenses, as with Trimble Total Station, the company staff could measure the structures instead of paying to external surveyors. And as they transferred the measurements of the built structure directly to Tekla, they saved time and labor with not having to enter the measuring data manually.
Tekla BIMsight 2nd Anniversary contest:
This success story was entered to the Tekla BIMsight 2nd Anniversary contest for Tekla BIMsight users. Panorama City is one of the two winning projects because of the extent of Tekla BIMsight usage and the extent of the entry.
Panorama City, a shopping and entertainment center in Estonia with a total area of 93 350m2 (1 004 810 sq ft) is scheduled for opening in spring 2015, hosting 200 shops and sporting and other facilities. It would not be completed without Architectural Design Office Pluss, which currently works on architectural design and coordinates the work of the design consultants working on HVAC, electrical and structural design.
From the beginning, the project team has used several BIM tools including Autodesk Revit, Tekla Structures, CADS Planner and MagiCAD to name a few. The client, construction contractor and most of the designers have access to the centralized model.
Pluss wants to identify the conflicts before they reach the construction site, and also pioneer with using the models in the longest project phase – maintenance. Tekla BIMsight has a central role in the design and construction coordination part of the project. The Project Manager, Tanel Friedenthal from Pluss explains:
- "We decided to use Tekla BIMsight as the central platform to manage the design process for three reasons: First, fast navigation when working with large models; second, cloud-based project folder support; third, very short learning curve, which is especially important for non-professional project parties. At the moment, near the end of the design development phase, we have imported close to 800MB of subcontractor IFCs and 3D DWGs to create the centralized building information model in Tekla BIMsight."
Pluss chose the file-sharing service Dropbox to exchange large scale IFC files in real time which proved to be a leap forward in project collaboration.
How to deal with all those bytes?
When the number of bytes counts, Panorama is a very large project having 800MB and a wealth models. Due to the large amount of data, Pluss had to invest in liquid-cooled 12-core PCs to maintain the architectural Revit models.
When it comes to Tekla BIMsight, performance is not an issue: , the client and the general contractor view the centralized Tekla BIMsight model on their office laptops. .
“For my 2009 laptop it takes approximately 3 minutes to open up and load 44 referenced models close to 800Mb in total. At the same time, the desktop workstation performs the same startup procedure in 1min 50s,” Tanel Friedenthal tells.

Four years ago, the engineering company Polysius Vietnam received a request from parent company ThyssenKrupp Polysius in Germany to produce 3D models for some structures. They needed new tools to fulfill the order. After evaluation, Polysius Vietnam chose Tekla Structures for its advantages, such as ability to combine both concrete and steel structures in one model and its compatibility with PDMS, a 3D software solution for plant engineering.
After starting to use Tekla software, Polysius Vietnam Ltd. has moved on to designing cement plants for the world instead of just Vietnam.
- "At first, our intention was not to use Tekla to actually design a cement plant,” says Mr. Roland Chudalla, the Deputy General Manager of Polysius Vietnam. “However, as we got used to it, we found it a more efficient way of designing. It also opened new possibilities for us, enabling us to design and build complete, complicated buildings or structures for cement factories.”
Tabuk cement company order
For Tabuk Cement Company’s cement grinding plant in Saudi Arabia Polysius Vietnam designed six plant buildings. As half of the main building was underground, the team included the excavation pitto the Tekla model to achieve the excavation quantity. They also modeled the rebar, generated accurate bills of quantity from the model and sent the bills of quantities to the contractor on site to use for ordering concrete. The team could foresee and avoid difficulties in rebar installation, spot clashes between rebar and rebar and cast-in items, and the software proved useful for controlling budget overruns from project modifications.
Even though the complicated plant was the first project Polysius designed from scratch with Tekla, they succeeded in completing the work in just five months. Without Tekla, they would have needed 7-8 months.
-“Tekla reduces the time and manpower required to do the quantity take-off and allows us to come up with bids quickly, accurately and competitively,” states Mr. Nguyen Dinh Quan, Head of the Engineering Department at Polysius Vietnam.
