GRAHAM has been appointed to deliver stage two of the Didcot and surrounding area major infrastructure (HIF1) scheme.

Leading on the design of the Clifton Hampden Bypass and Didcot to Culham River Crossing, the scheme aims to address traffic congestion, improve journey times, and enhance connectivity between Didcot and surrounding areas, whilst supporting the creation of new jobs and economic growth in the Science Vale region.

Detailed design is currently underway, with construction expected to start in early 2026.

The procurement of GRAHAM for the Design and Construct projects has been facilitated through Crown Commercial Service's Construction Works and Associated Services framework.

Andrew Henry, GRAHAM Contracts Director said:

“GRAHAM has been working closely with Oxfordshire County Council and key stakeholders since April 2023 through Early Contractor Involvement (ECI).

This collaborative approach has enabled us to develop the detailed design for these significant infrastructure projects while actively engaging with third-party stakeholders such as Thames Water and Openreach to coordinate necessary utility diversions”.

“As we deliver this transformative project, we will focus on working closely with the local community to create a lasting impact that benefits everyone”.

Councillor Judy Roberts, Oxfordshire County Council’s Cabinet Member for Infrastructure and Development Strategy, said:

“GRAHAM has worked on similar projects around the country and have a high commitment to social value and giving back to the local area. Their bid was successful as they understood the scheme and its complexities and how the four elements need to tie together.

“This transformative infrastructure development will offer more sustainable travel options in and around Didcot and support the creation of new jobs and economic growth in the Science Vale region.”

Dawn Matthias, Deputy Director, Construction at Crown Commercial Service said:

"The Crown Commercial Service Construction category team worked closely with Oxfordshire County Council to support a compliant route to market in line with the aims of the Construction Playbook; and we are delighted to see these projects progress to this stage. These initiatives not only promise to enhance local infrastructure but also deliver significant social value and tangible benefits to residents in the community."
