It is the first phase of plans for a new £50m stadium complex for the club.
Morrison will take control of the site at Kingsford as soon as the earthworks are finished and then project manage the construction through to completion in summer 2019.
Work will include the construction of the training pavilion, groundsman’s accommodation, three professional training pitches, two 3G pitches and one grass pitch.
Morrison is in the process of appointing all the subcontractors – the majority of whom are local firms.
WM Donald has been appointed to carry out the civil engineering, Hunter Construction will deliver the 3G pitches while specialist company, Greentech, will create the professional training pitches and Hutcheon Services will design and install all mechanical, plumbing and electrical services.
McIntosh Plant Hire were awarded the contract for the earthworks and ground remediation earlier this year.
Project director, Raymond Edgar, added: “Today’s contract award is another major milestone in this project.
“We committed to appointing local firms where possible so that our overall £50m investment secures and creates jobs and boosts the local economy.
“I’m pleased to say that we have been successful in delivering this promise for this first phase of the project.”
