Bringing to life Pre-engineered Indoor Stadium designed in Tekla Structures
Zamil Steel India was tasked with designing, fabricating, supplying, and erecting the Lucknow Indoor Stadium in India, a stadium with unique geometries. Tekla Structures enable the Zamil Steel team to do error-free detailing of the unique structure.
Established in 1977, Zamil Steel specializes in designing, fabricating, and supplying Pre-Engineered Steel Buildings (PEB). Over the past 44 years, it has grown from a local, single-division company into a leader in the growing field of steel fabrication in Asia, Africa, and Europe. The company has supplied over 90,000 buildings to more than 90 countries worldwide, from Panama and Mexico in the West to the Philippines, China, Japan, Australia, and South Korea in the East. In India, the company is headquartered in Kharadi, Pune.
Pre-engineered Indoor Stadium in Lucknow
Zamil Steel India was entrusted with the task of designing, fabricating, supplying, and erecting the pre-engineered steel building for the 5200 square meter Lucknow Indoor Stadium, Lucknow, India.
“We execute all of our projects only on Tekla for a number of reasons - it extensively supports jobs with revisions, 2D drawings and 3D models created in Tekla are accurate and meets our clients’ needs perfectly, it allows us to build even the most complex of structures with relative ease. Moreover, Tekla supports a number of formats including SNDF and IFC. Efficient designs and constructibility are easily achievable with Tekla, which helps us meet our clients’ high expectations, ultimately increasing our productivity and profitability.” says

Constructing the complex, arched stadium structure
The significantly complex structure of the stadium had very unique geometries to cater to as well. A truss system was used to provide framing action for this structure, where each truss was designed as a combination of several segments. The design for this structure involved a high level of coordination with the fabrication team, erection team and the transportation team.
Some of the major challenges faced during the design stage of the project were:
- The designers had to closely coordinate with the fabricators to reaffirm whether the structural members used in the design were suitable for bending or not, and accordingly, the design had to be modified/updated.
- Considering the challenges that were expected during the erection process, the design team had to choose the most appropriate connection system carefully.
- The roofing system also had to be considered while considering the structural arrangement.
- Transportation of trusses in curved segments was in itself a big challenge. Each segment length was decided to accommodate the maximum number of segments on each trailer.
- The most important part was to design a steady structure with optimum steel consumption.
Tekla Structures - the most accurate software for all steel structures
“Considering the structure's shape, executing it in 2D AutoCAD was very challenging. Tekla Structures allowed us to do error-free detailing of the unique curved structure with absolute ease.”
Mr. Rao, Zamil Steel India
Besides, NC files generated in Tekla facilitated the project executing team to fabricate the curve members accurately, saving man hours on-site and during fabrication. Tekla also greatly enhanced the overall construction quality via tools such as 3D views and live schedules.“ Mr. Rao added
Along with Tekla Structures, Tekla Model Sharing enabled the project executing team to work collaboratively, irrespective of location, during the tough times induced by the pandemic.
Last but not least, raw material estimation made at the beginning of the project helped the production team to arrange the material “just on time” when the job was released for fabrication.
