Miller Construction has been appointed preferred contractor for £48m of work across 13 schools in the South-east.
Work covers refurbishments on three schools in Hampshire, Reading and Surrey worth £13m, and pre-construction services for 10 schools in Surrey worth £35.5m.
Miller Construction has been appointed by a group of four councils, comprising Hampshire County Council, Reading Borough Council, Surrey County Council and West Sussex County Council.
The councils are working together to procure construction services for about 30 schools in the South-east with a combined value of up to £100m.
Refurbishment and new-build projects aim to address the rising pupil numbers in classrooms at both primary and secondary school level.
Miller Construction chief executive Chris Webster said: “This appointment reiterates our continued commitment to our strategy focusing on long-term partnerships and framework agreements.
“We have a proven track record in the education market and we are confident the schools we deliver as part of this framework will leave behind a positive legacy for the pupils who will use them.
“Through close collaboration with Reading Borough, Surrey County and Hampshire County Councils, we aim to deliver facilities that will meet the changing face of education and provide inspiring learning environments,” he added.
The Improvement and Efficiency South East local authority framework has been selected to deliver the work.
IESE is a local authority four-year framework led by Hampshire County Council. It is used by over 30 local authorities in the South-east and London for public sector projects.
Work is expected to be completed by September 2015.
