The Plymouth deal will be Bam’s fifth win this year under the new academies framework.
All Saints Academy Plymouth was one of 71 Academies awarded a capital funding grant in December 2010.
Existing 1960’s and 70’s buildings will be demolished to make way for new buildings while the school’s 1980’s east wing building will be refurbished under the £11.5m deal.
It is estimated that 80% of the contract value will be spent in the local economy, so it will directly contribute to the city’s growth.
Bam Construction has committed to create apprenticeship opportunities, giving young people opportunities to train whilst in employment.
The Academy will hold a public consultation of the planned proposals on the 27 March between 5:30 and 7 pm in the Brunel Centre and the planning application will be made shortly after this.
Graham Kingdon, area manager for Bam Construction, said: “We are very pleased to have been awarded preferred bidder on this contract, particularly after also winning the preferred bidder on Plymouth UTC and the Marine Academy Plymouth.
“Winning these contracts has been a key target for us as we want to invest in Plymouth as many of our staff and supply chain partners live and work in the area.
“We see Plymouth as an up and coming city and an important place to be doing business. This is why we have targeted these contracts and have worked extremely hard to offer the city extremely good value for money.”
