Motorway operator Connect Plus (M25) has picked Jackson Civil Engineering, Octavius Infrastructure and Milestone Infrastructure to deliver the COFA3 call-off framework that will run for six years.

Works includes highways construction and improvements across Hertfordshire, the South East and East of England.

The works will be built into contracted packages typically valued between £500,000 and £3m.

The three firms previously held the COFA 2 deal alongside a fourth contractor R&W Civil Engineering, which collapsed last month and was bought in administration by Octavius, formerly the Osborne Group infrastructure arm.
