The first phase of Lend Lease’s major development in Stratford. The project consists of two residential blocks of 17 and 30 storeys. RC frame construction starting with large foundation pads above piles.

A central core on each tower achieved using jumpform systems typically three floors ahead of slabs. This system produced a good finish on the walls requiring only minimal re-work to allow for direct painting within stair cores. Floor slabs typically 550 – 600 m2 each incorporating precast balconies at the perimeter.

The balconies included a cast in thermal break and connection bars. This allowed the balconies to be installed prior to the concrete pour for the slabs. Average six-day cycle achieved for floor slabs. Two sets of screens were used on each tower; the first used to encapsulate the concrete works at the top as the structure progressed; the second used for cladding works on completed structure below.
