Exceptional engineering
State-of-the-art construction above Transport for London tunnels
The car park is strategically located on the Heathrow Airport site, close to Terminal 4, making stakeholder coordination essential to the project’s success. The site is located above both the Piccadilly Line and the Heathrow Express Tunnel (HAL), requiring a unique construction solution. Huber Parking used shallow pad foundations, supported by finite element modelling techniques, which assured stakeholders of the suitability of the design. The tunnels below were fitted with monitoring equipment to track any movement during construction. Three staircases are fitted with fire-resistant steel doors with vision panels that are colour-coded to match the colour scheme of the protective waterproof coating on the parking decks while a lift completes the comfort features of this MSCP. Curtain wall windows in the main staircase provide natural daylight and perforated powder coated steel cladding strips meet ventilation requirements.
