Heathrow T2A

Completed Projects

Heathrow T2A was a high-profile project in challenging surroundings, with construction taking place within a live airport environment. Demonstrating success and best practice was vital on a project widely perceived as representative of the nation. T2A was the first airport terminal in the world to achieve a BREEAM Excellent rating, serving as an iconic gateway to Britain and helping to meet Heathrow’s aspirations for the 21st century.

Design & Build - NEC3 Option C

The T2A site lay at the heart of the world’s busiest international airport at the time, posing complex logistical challenges. Not only did we complete the entire T2A project with no disruption to airport operations, nor to the 334 million passengers who passed through Heathrow during the works, we set a new safety record for the UK: we completed over 5.5 million consecutive hours without a RIDDOR accident.

This highly complex and restricted site was in the proximity of four other terminals and the southern runway. In close collaboration with the airport and security services, the landside/airside boundary was moved 15 times to allow for phased construction to progress on a site not constrained by working in an airside environment. Additionally, London Underground’s Piccadilly line runs under the site, crossing diagonally at a depth of around 8m. We used sophisticated monitoring systems to ensure that settlement remained within the required tolerance levels.

The new T2A is a result of years of planning, design and delivery to ensure operational readiness from Day One. The terminal opened on time, with the project finished safely, to the highest quality and on budget.


  • T2A became the UK’s safest construction project – with 5.5 million consecutive RIDDOR-free hours
  • 1st airport terminal in the world rated BREEAM Excellent - a fitting gateway to 21st century Britain
  • 35,000 new construction jobs were created, of which 80% employed were local workforce, 45% above the proposed target
  • 99% of materials from the old terminal building were recycled
  • Over 50,000 deliveries to site were co-ordinated by our logistics team during the works
  • T2A achieved 40% reduction in CO2 emissions compared to the minimum requirement for a new building

”The excellent work here reflects best practice in infrastructure delivery, progressing on time and to budget, working collaboratively with its suppliers. This is a great example of successful project management and delivery in the UK.” 

Lord Deighton, former Commercial Secretary to the Treasury speaking of the T2A project

  • Passenger capacity increased by 20 million per year
  • 3,000 structural steelwork and M&E modules manufactured offsite
  • 300 people working within our design development team
  • 4,000 operatives at peak, 75 subcontractors and 200+ suppliers
