A substantial earthworks project for Heathrow’s T2B

As part of a major capital investment programme, a satellite building, T2B, has been built alongside the new main Terminal 2 at Heathrow Airport.  It will serve half of the 20 million passengers who will pass through each year.

McGee was employed as a subcontractor to Balfour Beatty to provide Civil Engineering services in carrying out the vast earthworks for the new building over a period of 104 weeks.

In a high profile project offering multiple challenges, we called on in-house expertise and considerable experience to deliver a comprehensive and high quality service.

The scope of works was vast and required a massive basement excavation, requiring approximately 600,000m³ of earth to be removed.

In-keeping with the building’s philosophy for innovative construction, and built to the latest environmental standards, 30,000m³ of the arising concrete produced was crushed and recycled on site for later use in the construction of haul roads. 100,000m³ of the arising gravel was also stockpiled on site for final backfilling around the completed structure.  All this helped the project to be the first UK airport structure to be recognised by the Building Research Establishment Environmental Assessment Method (BREEAM). 

T2B is the largest airside construction project ever carried out at Heathrow and we are exceptionally proud to have been involved.
