- 2254 cubic meter M60 grade concrete
- 4283 MT of aggregates
Concrete is being supplied through two in-situ batching plants of the capacity 120 m3 capacity each. Concrete pouring was temperature controlled to keep pouring temperature below 25 Degree Celsius, through in-situ ice and chiller plants.
Sufficient waterproofing measures have been ensured before casting the slab.
