UK-based construction group Miller Construction has secured a £156m contract from the Education Funding Agency (EFA) to deliver the second batch of schools under the government's PF2 private finance model.
The construction value of the projects is worth more than £100m and Miller will also be responsible for maintenance and lifecycle services for 25 years, which is worth £55m.
The second batch of schools is part of the Priority School Building Programme of EFA.
The project is scheduled to be finished by August 2016 and includes the construction of six secondary schools and six primary schools in the North East of England.
The six secondary schools in the batch include The Duchess's Community High School in Northumberland, Longbenton Community College in North Tyneside and Seaham School of Technology in County Durham.
The six primary schools include Hylton Castle Primary School in Sunderland, Mandale Mill Primary School in Stockton on Tees and Roman Road Primary School in Gateshead.
The programme will provide new facilities for more than 8,350 pupils across the region and 188 nursery places.
Miller Construction CEO Chris Webster said that in-line with the company's strategy of providing integrated solutions across the full property lifecycle, they will fund, design, build and care for the schools.
"This latest appointment builds on our track record of delivering and maintaining high-quality and best value learning environments that support improved educational achievement," Webster said.
"We now look forward to working closely with the schools to finalise the designs so we can start to deliver these class-leading facilities that will benefit staff, pupils and communities for many years to come."
