Finnesa Capital needed a large industrial facility at Indore (MP) built fast and without a forest of internal columns interrupting the floor. The brief: 235,320 sq. ft. of pre-engineered building with a 106 M clear width and a long cantilever mezzanine, delivered ahead of the production schedule. Here is how ETS engineered and executed it.
The Challenge
The facility had to deliver completely column-free floor space across a 106 M width — split into 34, 32, and 30 M spans — so that material flow and machinery layout were never dictated by structural supports. A 10.0 x 168.5 M mezzanine added a further constraint: it needed a 2.0 M cantilever beam carried without column support.
On top of the geometry, the programme was tight. The client wanted to begin production cycles as early as possible, which ruled out slow, weather-dependent on-site welding and conventional RCC timelines.
The ETS Approach
ETS designed the structure as a rigid frame with tapered columns and rafters in STAAD.Pro Connect Edition, optimising steel to the precise load path of each span. Every plate, bolt hole, and connection was pre-punched and cut on CNC machines directly from the STAAD outputs, so components arrived 100% bolted — taking site welding off the critical path.
Fabrication ran in parallel with site clearance: primary and secondary members, purlins, and girts were fabricated, painted, and coded while the ground was being prepared. Components then arrived in a pre-determined erection sequence, letting a small crew with a crane tilt up and secure frames immediately. HVAC ducting was suspended from the Z-purlins and services routed through pre-punched holes in the rafter webs, keeping the floor clear.
The Results
By shifting 100% of fabrication to factory settings, the project saved massive design cycles. Sequential erection optimized resource footprint on ground. The complex cantilever mezzanine works safely up to its max design threshold, proving structural engineering viability without physical layout changes over future spans.
