Tekla was established in 1966, and today has customers in 100 countries, offices in 15 countries, and a global partner network. Since 2011, Tekla has been a part of the Trimble Buildings Group. Trimble Buildings Group’s solutions tightly link office-based process and information with the field crew. Trimble Design-Build-Operate platform responds to the needs of owners and the AECO industry by increasing productivity and reducing rework. Tekla provides a BIM (Building Information Modelling) software environment that contractors, structural engineers and detailers and fabricators of all materials can share.
Tekla software creates, combines and distributes highly detailed, constructable 3D models. Information-rich models lead the way for production control and more collaborative and integrated project management and delivery.
Tekla BIMProviding a suitable solution by using the right technology across the disciplines of building design and construction while considering the requirements of accurate construction and preliminary clash detection, Interarch decided to adopt Tekla BIM. Traditionally known as a company that caters to the PEB segment, Interarch today has gone beyond PEB.
Interarch decided to have a fully integrated approach towards design and execution when choosing technology. Going by its Parent companies value to deliver on time and restrict errors, it decided to go for a model based approach which could provide all the information at the beginning of the project. After comprehensive research, Interarch chose Tekla for the purpose.
Accuracy and timelinessC Interarch chose its BIM solution to deliver the accuracy and on-time delivery for the most complicated designs. It chose Tekla over many other products after an exhaustive evaluation period. It also found that feasible to customise the software according to the requirements.
“With the help of this solution we are able to design the most complex structures with ease and we are able to deliver within the timelines,” says Sanjay Modi, CEO, Interarch. “Tekla software is easy to adapt, and it is very useful to build a complex structure according to any requirement.”
Detailed documentation and fabricationC Interarch uses Tekla for many different types of projects ranging from architectural creations to process plants. In each project, the major challenge is to tackle complexity with ease. It creates 3D models from reference files, and also creates built-up sections and custom components while modelling to serve the complex nature of their projects. It delivers the projects with highly detailed documentation and fabrication drawings.
In many projects, the company works on multiple software packages and does clash detection and coordination review using the Tekla BIMsight application.
“Tekla is life line for steel detailing for Infrastructure projects which are extremely complicated. Currently we are using Tekla Structures and Tekla BIMsight for all our projects, to mitigate risks involved in delivery,” says Mr Modi. 
Tekla BIMsight Tekla BIMsight is a free professional tool for construction project collaboration. Anyone can combine models, check for clashes and share information using the same easy-to-use 3D environment. With Tekla BIMsight project participants can identify and solve issues already in the design phase.
Collaboration and involvementC Interarch chose Tekla BIMsight over many tools for doing the coordination review of several building information models and checking the models. Clash detection between files from multiple domains is conducted using Tekla BIMsight, and the reports are used by project managers on various stages. From creating a quick visualisation to creating mark-ups to clash detection and management, the team uses BIMsight effectively.
Iconic BIM projects in IndiaFor Interarch, it was more about the process when it decided to go ahead with a BIM-based process. Its projects display high-end detailing despite many constraints, and it believes success has been possible due to adopting the right technology. Tekla BIM has helped it overcome many hurdles in its most iconic projects.
Project: Cricket Stadium, Trivandrum This project was awarded to Interarch Infrastructure by IL&FS for detailing, manufacturing and execution. The stadium structure is made of pipe sections which needs 3D complex detailing. With Tekla structures it could avoid mistakes during manufacturing and execution at site.
Project: C.P.IndiaThis is a multilevel process plant located in Pune with a 6-storey structure supporting various equipment at the height of 45.1 metres with a 32-metre long transfer structure. The specialty of this project was to customise the structure supporting the equipment according to the client’s equipment details which appeared on every floor in an irregular manner. Using 3D BIM helped by superimposing the customer’s requirements in the model and then identifying the exact locations of all the openings and the equipment. Another significant challenge in this project was to make the transfer bridge of 32 metres with 20 megatonnes of weight resting on the RCC structure at other end. With the help of the client’s drawings, Interarch identified the exact locations of the existing structures and created connection details that suit the requirements, all implemented in Tekla structures software.
