The three-storey building will include a radiotherapy centre and is the third scheme to be awarded to Norwest Holst by the Pennine Acute Hospitals NHS Trust.
It is also one of two new jobs to be added to the contractor’s order book for the new year.
Norwest Holst today said it had been awarded a £9 million contract by Milton Keynes Council under their education and leisure framework.
The 61-week contract includes a three-storey extension to the existing Hazeley School and the construction of a new two-storey building.
It is expected both jobs will start on site in mid-January.
