18 London Underground was constrained by the lack of coherent information provided by Metronet on individual projects. Both ex-Metronet employees and Tube Lines told us that London Underground's inflexible interpretation of the PPP contract's requirements did not give sufficient consideration to cost or delivery of the work. They also told us that late requests by London Underground led to late revision of station access plans and late changes to arrangements over suppliers, materials and design.
19 London Underground has, however, provided us with examples where it made pragmatic commercial decisions to aid Metronet in the completion of its works. These include changes to reduce the scope London Underground considered necessary to speed up the delivery of Metronet's work. Northfields Station Enhanced Refurbishment - Tube Lines
