The key change in the enlarged MSF4 framework line-up sees John Sisk take Morgan Sindall’s place among the big four contractors.
Galliford Try, Balfour Beatty and Eurovia have each renewed for the 8-year term.
Eight firms are understood to have originally been shortlisted to bid for the framework.
The pipeline of works has doubled in size to an estimated £1bn following the merger of three regional efficiencies groups, the Midlands Highway Alliance, the Midlands Service Improvement Group and the West Midlands Highway Alliance.
MPA+ now counts 35 local highway authorities from across the Midlands and beyond as members.
Owen Jenkins, chair of the Medium Scheme Framework Board, Oxfordshire County Council said “We are all aware that this is a turbulent and challenging time for local highway authorities and the construction sector.
“We are therefore very pleased to be announcing MSF4 and this embeds the need for the whole sector to work together to meet the challenges of the future.”
Bill Hocking, Chief Executive of Galliford Try, added: “The MHA+ framework is a key part of the strategy for our Highways business going forward.
“We look forward to working with the MHA+ and its client authorities to making a lasting impact on infrastructure around the country.”
