The Delegated Decisions by Cabinet Member for Place, Environment and Climate Action meeting is scheduled to discuss the award of a significant construction contract for the HIF1 Didcot to Culham River Crossing scheme. This project is a key part of the wider Didcot Garden Town Housing Infrastructure Fund (HIF1) programme.

HIF1 Culham River Crossing Construction Contract

A primary item for discussion is the potential award of the Stage Two NEC4 Engineering and Construction Contract for the HIF1 Didcot to Culham River Crossing scheme to John Graham Construction Limited. This contract is part of the Crown Commercial Service Construction Works and Associated Services Framework. The report indicates that this decision is subject to the agreement of the target cost and programme for the works, finalising contract terms, and confirmation of sufficient funding.

The report outlines that the Didcot to Culham River Crossing is a crucial element of the HIF1 package, aiming to improve connectivity between Didcot and Culham, alleviate traffic congestion, and support the development of over 12,655 new homes and substantial employment growth across the Science Vale. The scheme involves constructing a new road, including a bridge over the River Thames and another over a private rail siding, with integrated walking and cycling facilities.

The report highlights that the project is funded through the Housing Infrastructure Fund (HIF) grant, supplemented by council capital allocations, Local Enterprise Partnerships (LEPs), and Section 106 contributions. The estimated construction cost is approximately £151 million, with the target cost yet to be finalised. The report stresses the importance of awarding this contract to maintain programme momentum and ensure the expenditure of the Homes England grant within the agreed timeframe of March 2028, warning that delays could jeopardise funding.

The report also details proposed agreements with FCC Environment UK Limited and Hanson Quarry Products Europe Limited. These include a Works and Access Agreement relating to land at Sutton Courtenay, and a two-party Overbridge Agreement and a Restoration Agreement concerning land at Bridge Farm Quarry. These agreements are necessary for the construction and subsequent restoration of the area.

The report also mentions that the contractor will be required to provide social value, which may include creating local employment opportunities, minimising the carbon impact of construction, and supporting local communities. The current programme indicates that main construction is anticipated to run from May 2026 to October 2028, with the Homes England funding period ending in March 2028.

The meeting is also scheduled to address questions from County Councillors and allow for petitions and public address, providing opportunities for public engagement on the items being considered.
