Lodha Platino
High rise residential tower
Detailed analysis and redesign of the structural system planned for a new 105m residential tower has enabled Whitby Wood Pritamdasani to deliver a buildable solution that meets India’s new more-stringent building code for high rise concrete structures.

Lodha Platino is a 33-level tower set in a larger residential complex developed by our client, Lodha Group. The site is east of Sanjay Gandhi National Park In Mumbai, not far from the Ulhas River. Basements are not required for the building, and as the ground has a high bearing capacity, a foundation system consisting of individual and combined footings will be used. Parking is accommodated at ground level.

Among the changes made in the new earthquake code is an increase of 20% in the Importance Factor in relation to the ability of tall concrete buildings to resist seismic effects. This means that new structural systems need to be designed for higher earthquake forces. The original structural solution for Lodha Platino had relied on the strength of its core. We re-engineered the concrete frame, increasing the amount of reinforcement in critical elements, and re-working the reinforcement in boundary elements on higher floors to ensure overall use doesn’t go up drastically. There is no increase in the sections sizes, so cost increases are minimised, and a complete re-design has been avoided.

The footprint of the tower measures 58m x 25.3m, with a floor-to-floor height of 2.9m. The structural system includes 150 and 175mm deep slabs, with shear walls connected to each other by the network of slabs, acting as in-plane rigid diaphragms for each floor. The shear walls control deflections and resist lateral forces on the tower.
