Its new framework will be split into five English regions and cover mainly refurbishment and remodelling work.
The plan is to use the firms to deliver typical contracts of £3m-£5m, but could include projects from £200,000 to £10m.
The Agency plans to hold a suppliers day in Sheffield on 18 October to set out its plans for the new programme of work.
Procurement chiefs will stir up controversy among smaller regional contractors because the present plan is to exclude firms with turnover of less than £25m. This calls into question the Government’s commitment to supporting smaller contractors and suppliers.
The new upgrade framework is to be rolled out across the full spectrum of education facilities from free schools, university technical colleges, studio schools, Academies Capital Maintenance Funded schemes, basic needs and other work programmes.
Bids will be invited on 25 November with successful contractors unveiled early in the New Year on a programme that will run up to July 2018.
