Heathrow Staff West Car Park, Hounslow, UK

Synopsis:
Substructure, superstructure and surface water drainage design
Contractor:
Trafalgar House
End Client:
British Airport Authority

A fast-track approach to achieve 1220 car parking spaces on four levels, adjoining an existing three level car park.

Temporary Ramps had to be erected to serve the existing car park before the original circulation ramps could be demolished and construction of the new car park commenced. Retaining walls for the lower, partially sunken level were eschewed in favour of reinforced earth banks which utilised the spoil from both mass and local excavations.

The superstructure comprises 15m long precast prestressed floor units on insitu beams and columns which were designed to be self-stable during construction.
