The urban plan envisages the widening of the sea front area with sea-works, creating the space for a 32,000m2 car park, a tower building (the Sail) of approximately 18,000m2 and a underpass connection through the site. The car park is built with a direct waterproofing system of the concrete, made up of raft foundations, precast pillars and light-weight waterproof concrete floor plate. The Sail building is braced by reinforced concrete cores on composite steel-concrete columns and on-site floor slabs. The underpass tunnel uses “top-down” technology in its construction.
