Bolton Council has selected BAM to be its preferred partner for the building work on Kearsley Academy.
BAM beat off competition from Balfour Beatty to win the work. The school will benefit from a complete rebuild, with work scheduled to begin in December, and expected to be completed by March 2013.
BAM's plans for Kearsley will be on show at the academy on Thursday, September 8, between 4pm and 7.30pm. The academy, formerly known as George Tomlinson School, will accommodate 950 pupils, from 11- to 18-years-old.
Cllr Nick Peel, Bolton Council's executive member for children's services, said: "The plans put forward were really impressive, and will create an excellent learning environment for the academy's students. I am looking forward to seeing the plans become reality."
Roger Alston, of Kearsley Academy's sponsors, Northern Education, and chairman of the governing body, said: "It was a very difficult choice between the two companies, as both were excellent and had worked really hard, but BAM's plans just had the edge, it's a truly outstanding building.
"I'm really looking forward to working with them and seeing the plans come to fruition."
