New College Doncaster will be built in Auckley on the playing fields adjacent to Hayfield Lane and will open to students in September 2017.
BAM was appointed as preferred bidder using the Education Funding Agency framework.
Planned works include a 100,000 sq ft sixth form college with individual learning zones based around a multi-functional hub including informal learning, social spaces and extensive sports facilities.
Tony Fitzgerald, BAM’s pre-construction manager, said: “New College Doncaster has a fast-track construction programme starting in August 2016 and completing in phases ready for the new academic term in September 2017.
“We’ve been paying great attention to detail to ensure our design solution meets the college’s brief and can be delivered on time.”
