Stansted Transformation Programme

The Stansted Transformation Programme is the airport’s most significant investment since the terminal opened in 1991, expanding capacity and upgrading facilities to accommodate more than 40 million passengers a year. Delivery of this £1.1bn investment programme is taking place across a live operational airport, both airside and landside, while more than 30 million passengers continue to use the terminal each year. The programme comprises multiple interdependent projects, packages and contractors running concurrently, making sequencing, access and coordination critical to maintaining day-to-day operations while progressing a major five-year programme of change.

G&T is providing Cost Management and PMO services across the programme, including estimating, procurement, commercial management, programme management office support scheduling, change management, risk and project controls. Our embedded team supports Manchester Airports Group from early design through delivery, preparing estimates and benchmarks at each design stage, reviewing contractor pricing, managing change and reporting forecast outturn cost each month. This integrated approach is helping maintain consistent cost and programme information across multiple workstreams, giving the client a reliable basis for investment decisions as individual projects move through design and construction.

The programme is progressing from enabling works into main delivery with G&T optimising visibility and commercial control across cost, programme and individual project interfaces. Early phases are complete or underway, including the domestic arrivals building, enlarged security hall, Satellite Two refurbishment and baggage system upgrades. A construction partner has also been appointed for the skylink walkways, which will enable delivery of the 16,500m² terminal extension. G&T’s combined service solution is helping maintain coordinated decision-making as the transformation advances towards a major increase in airport capacity.
