Heathrow’s new Terminal T2B sets benchmark for sustainability

Balfour Beatty Heathrow World infra news

Terminal T2B, the largest “airside” construction project ever carried out at Heathrow, has been awarded the first ever BREEAM certificate for a UK airport building. Construction contractor, Balfour Beatty has successfully integrated a range of sustainable initiatives for the new Heathrow Terminal 2B satellite terminal helping the building achieve a BREEAM rating of “Very Good” for sustainable construction, design and innovation.

Measuring half a kilometre in length, the £590 million project has included the construction of the largest diaphragm wall in Europe as well as the use of over 165,000 cu m of reinforced concrete and 5,000 tonnes of structural steel. Replacing the old 1950s Terminal 2, T2B will provide 16 new aircraft stands, approximately 1,275 sq m of retail space, three passenger lounges with a floor area of 3,600 sq m, and extensive basement space for future baggage handling systems and a track transit system linking to a future Terminal 2C.

Balfour Beatty’s implementation of Building Information Modelling (BIM) has significantly improved project efficiencies and has assisted in allowing the construction to continue with little or no impact on air-side activities.  Working in close collaboration with client Heathrow Airport Limited (HAL) and in collaboration with the project supply chain, the adoption of BIM from the ‘ground up’ has significantly increased project efficiencies and offered minimal disruption to wider airport operations. 4D modelling has been used for effective planning and off-site manufacturing has been utilised, with 549 offsite modules provided.
