The project involved the construction of large RC Frame with a 16 and 22 Storey high towers.
It was located over existing piles from a demolished building that had to be mapped to negate the “pin-cushion” effect.
The structure had 1800mm wide concrete Fins that extended out of the building up to 22 floors on all elevations.
The Roof had a RC Skyframe –a double-height canopy that extended around the perimeter with slender columns and slab.
Complex removal of existing foundations
Bulk dig excavation.
Post-Tensioned Slab Construction.
Use of Solid Walls for the Fins.
Sequencing of works with Structural Steel Frame Installation.
There was deep drainage, sub-terranean refuse space and a new sub-station located very close to the building and crane bases.
Early contractor involvement-6 months before commencement, GCL was involved in the design development and value engineering-This resulted in approximately £750k being saved on materials and reduction of risk prior to commencement.
Use of PT design to make the structure lighter and reduce the loading on the piles.
Engagement and use of specialist precast Twin-Wall and integrated precast stairs.
Use of solid wall technology to replace the problematic Fins.
Introduction of a lightweight precast solution for the Skyframe thereby reducing H&S Risk for working at height.
