The new-style delivery integrator framework will see the firm work together with Heathrow to maintain and upgrade Terminals 1, 2 and 4.

The airport estate has been split into four of these contracts, which will cover mainly assets replacement, in a strategic shift away from major civil engineering projects.

Mace, Morgan Sindall and Ferrovial have picked up the other deals as part of a total investment package of £1.5bn.

These new frameworks, which appoint a single contractor to deliver a programme of projects, are hoped to capture year-on-year savings on the airport’s capital investment programme.

Balfour Beatty will act as programme manager and contractor at various stages throughout the lifecycle of the framework, delivering individual projects worth between £500,000 and £70m.

Projects will range from structural improvements to multiple asset replacements such as escalators and passenger conveyors, passenger and goods lifts, air conditioning systems, retail areas, CCTV, access and security systems.

At the end of 2016 there is an option to extend the framework for a further two years, which will be worth up to an additional £70m.

Balfour Beatty will bring its substantial range of in-house expertise to deliver the framework including design, engineering, construction, mechanical and electrical capabilities, and BIM which will allow full 4D design specification for Heathrow.

Steve Marshall, Balfour Beatty Executive Chairman, said: “I am delighted Balfour Beatty has been appointed to Heathrow’s new style of framework contracts. 

“We have worked in partnership with Heathrow for 15 years and we will continue to bring our leading capabilities in areas such as Building Information Modelling and safety to our work at Terminals 1, 2 and 4; and play our part in helping Heathrow maintain its position as a leading travel hub.”
