The London Olympic Village

The Olympic Delivery Authority is overseeing the works with property group Lend Lease, together with its construction arm, Bovis Lend Lease appointed as the development and construction manager. No7 comprises 7 Blocks, A - G inclusive, all having 12 floors, with post tensioning starting at level 1,2 or 3 depending on the Block and then on all floors up to level 12. The total area of post tensioned slabs is 28,000m2 approx.

The consulting engineers, Robert Bird Group, have designed these slabs as post tensioned in order to provide the thinnest and most efficient design; most are 225mm thick. The systems used in their design are mostly bonded tendons of 3 or 5no 12.9mm strands.

Mitchellson awarded the subcontract to Conforce to supply and install the P.T. system into No7 in July 2009. Conforce were able to demonstrate considerable experience in this type of large scale residential work and a sound track record with other concrete frame contractors in London. We were particularly pleased to be successful as there was intense competition from other UK post tensioning contractors for this work.
