We have recently completed this installation, it was for the new Westfield Shopping Centre in Stratford, London. It forms part of the development around the Olympics site. It is split into two seperate contracts: car park and above ground.
We installed car park ventilation systems in two car parks, a link road and three service yards. The installation consists of over 115 jet thrust fans and over twenty extract and supply fans.
Due to the size and weightof the supply and extract fans, it was necessary to lift them into place using a helicopter.
The above ground works consists of protecting the lobby areas and stairwells of over 14 cores. Some are AOV (Automatic Opening Vents) systems and some are mechanical extract systems with a pressure monitoring system.
