The firms are among 11 contractors to have won the fourth generation Southern Construction Framework, which promises a £5.25bn work pipeline.
They replace Bouygues UK and Balfour Beatty who have dropped out of the refreshed panel. Nine firms, including Galliford Try, Kier and Willmott Dixon retain places on the framework, which is due to come into force at the end of April and run for four years.
The current generation framework has delivered over £2.5bn of public projects, adding more than £110m of value for 75 public sector clients across the South West, South East, and London.
The framework is a joint initiative between Hampshire County Council and Devon County Council and has on average reduced costs by 1% in pre-construction, claim SCF chiefs.
Steve Clow, assistant director property and facilities, Hampshire County Council said: “We are delighted to announce the appointment of 11 contractors to the next generation of SCF. Our unique integrated team approach has helped to deliver significant benefits for Public Sector clients across the South of England.”
