Assurance Support for Lower Thames Crossing Cost Estimate by Turner & Townsend

About

Highways England awarded a contract to Turner & Townsend for technical services to support detailed reviews and assurance of the emerging Lower Thames Crossing cost estimate.

The estimate represents an Invitation to Tender Design, enabling Highways England to produce operational budgets before releasing information to the supply chain.

The contract involved a detailed independent assurance review of the Lower Thames Crossing Project works packages, including Tunnels & Approaches, Highways North/South, Enabling Works, and Enabling Works & Risk, VE, along with associated quantitative risk assessment from current day to completion and handover to operations.

The review tested that the Direct and Indirect Works, including detailed Bills of Quantities, reflected the full scope of works across development, planning, procurement, delivery, test and commissioning, and handover stages, and aligned with the project's key assumptions and exclusions.

The contract value was AUD 152,986.4.
