1.5 The annual payment that the Trust was contracted to pay once the hospital was fully operational remained unchanged during the construction phase of the project. Through the PFI contract the Trust had transferred the construction risk to THC Dartford who in turn transferred the construction risk to the construction subcontractor, Carillion, by a fixed price design and construction contract. For building the hospital and providing hospital equipment, Carillion received £95 million from THC Dartford. Carillion informed us that the mechanical and engineering element of the construction work was carried out at a loss resulting in Carillion only breaking even on its construction contract with THC Dartford. But the construction phase was still completed on time and the extra construction costs were not passed on to the Trust which is evidence of risk transfer under the PFI working.
