PLANNING DETAILS

Extremely reduced times for the new construction of two buildings with 10 floors above ground and 3 below.

STRUCTURAL SOLUTIONS

Composite steel-concrete beam placing speed together with the standardisation of operations to realise, floor by floor, each of the two towers permitted site management costs to be minimised, and the very quick completion of the building. Composite steel-concrete beam with concrete footing were used for the 3 underground decks coupled with pre-compressed hollow core slabs for a total of 26,000 mq, and composite steel-concrete truss for 10 above ground decks coupled with prestressed slabs for 45,800 mq of deck.
