Challenges

Located in close proximity to the river the plot is subject to frequent flooding during heavy rains. The client wanted to ensure power reliability even in case of extreme flooding events. There were 6 basements. As the footprints of basements were fewer, the challenge was to manage basement ventilation cutouts. Also, the local authorities insisted on having natural ventilation cutouts in addition to mechanical ventilation cutouts. Authorities were concerned about purging out smoke naturally in case of fire.

Solution

Access to Substation and DG room is designed to be above the maximum flood level. All the cable entries and ventilation ducts etc. into the substation and DG room are designed above this level. Detailed coordination was done with Architect. Basement wall punch-outs were proposed at places where we could manage open space requirements at the ground level. Detailed calculations were submitted to local authorities complying with their requirement. On every floor the facade was divided into two parts, top part opens automatically in case of fire and would allow the smoke accumulated in the office area to purge out naturally.
