The seven recommendations from the April 2019 contract award project assurance review are being addressed by Transport for London (TfL) officers. Due to the ongoing procurement process, some of the details cannot be shared at this stage, as they relate to ongoing commercial matters. The recommendations and the responses were notified to the TfL Programmes & Investment Committee as part of the approval process for the selection of a preferred bidder and award of the contract for the Silvertown Tunnel scheme.

The recommendations relate to: 


  1. The potential for procurement challenge
  2. The risks associated with a third party landowner
  3. The provision of appropriate TfL resources to provide proportionate oversight of the contract
  4. Further reviews of the proposed risk transfer mechanisms under the contract
  5. Further development of risk mitigation and management strategies
  6. Independent Investment Programme Advisory Group (IIPAG) reinforcement of recommendation 3 above
  7. IIPAG reinforcement of recommendation 2 above.
