Robertson has won a £9.5m contract to upgrade two sites at Northumberland College.
The college announced the redevelopment plans after a successful £3m bid to the Skills Funding Agency that was matched by £6.5m in its own funds.
Work will begin in January at the Ashington and Kirkley Hall campuses of the college, which is the northern county’s largest training provider.
The upgraded facilities at the Ashington campus will include new or refurbished workshops for construction, engineering, motor vehicles, brickwork, plastering, carpentry and decorating.
Robertson will also refurbish the ground floor of the main campus building to incorporate a new hair and beauty salon and a restaurant.
At Kirkley Hall, they will deliver new arboriculture and tractor workshops, and a new education block with eight classrooms and a learning resource centre.
Northumberland College principal Stuart Cutforth said: “We have been working closely with consultants and the appointment of Robertson means work on our campus improvements will start soon.”
Robertson’s regional magaing director, Andy McLeod said: “Works have been very carefully planned to ensure Northumberland College continue to deliver education and training to students whilst the campus upgrade is ongoing, we are also looking forward to working with the college and providing learning opportunities for students during the construction period before the works are completed in September 2014.”
