HCL Technologies Global SEZ IT Campus (OMR Sholinganallur)
Supplied over 6,800 metric tonnes of primary steel for HCL's state-of-the-art Special Economic Zone (SEZ) campus on Chennai's Old Mahabalipuram Road (OMR) IT corridor.
Engineering & Strategic Scope
The HCL Technologies Global SEZ Campus at Sholinganallur is a major technological hub on Chennai's OMR corridor, accommodating over 15,000 software professionals across multiple green commercial towers, central cafeterias, and an automated multi-level car park.
Architectural Expression & Spatial Dynamics
The campus prioritizes sustainable green building design with LEED Platinum certification. The office floors feature expansive 15-meter column-free spans that allow dynamic workstation reconfigurations, supported by composite steel-concrete floor systems with integrated raised access flooring.
Structural Rigor & Critical Environmental Criteria
High Groundwater Table: Situated near the Buckingham Canal, the 3-level basement raft faced severe hydrostatic uplift pressures, requiring dense Fe 550D rebar mats with water-tight mechanical couplers.
Vibration Dampening for Sensitive Labs: Server farms and hardware testing facilities demanded rigid structural beams with high resonant frequencies to eliminate floor vibration.
Thermal Solar Integration: Structural steel canopies over rooftop decks were engineered to support large photovoltaic solar arrays under cyclonic coastal winds.
