Heathrow Terminal 5 construction

Heathrow Airport, London, UK · 1987-2008 (conception to completion), 2002-2008 (construction) · £4.3 billion (2008 prices)

The judgement call

Account-gated at launch

The T5 Agreement, a cost-reimbursable contract, protected supplier profits and encouraged collaboration, leading to on-time and within-budget delivery despite its complexity. - Extensive use of off-site trials and testing was crucial due to on-site restrictions and the project's scale. - The project faced significant public inquiry, highlighting the importance of early stakeholder engagement and environmental impact assessments. - Initial operational issues post-opening, particularly with the baggage system, underscored the need for thorough testing and integration of all systems before launch.

Key engineering challenges

Managing the immense scale of excavation and construction within an operational airport environment. - Designing and constructing large span structures for the terminal buildings while integrating complex baggage handling and transportation systems. - Overcoming significant subsurface challenges due to existing rail tunnels and infrastructure. - Implementing an innovative procurement and contracting strategy (T5 Agreement) to foster collaboration and manage risks.
