The new building framework was originally expected to be worth around £6bn but has mushroomed to a forecast capital spend of £8bn over the next four years.
It will replace the existing £4bn main contractors framework, launched in 2013 to deliver larger school projects that expires in November.
This came in for a lot of criticism for being too main contractor heavy and later suffered for having a limited choice of pre-tendered firm as the recovery saw big builders turn down opportunities to bid for smaller school schemes.
Under the latest EFA plans there will be a total of 22 lots covering a wider collection of regions as well mid and low value projects.
The country will be divided into two regions – the north and south – for larger projects, in much the same way as before. This element of the programme will account for around £4bn of work.
Successful firms will help to deliver free schools, academies, university technical colleges, sixth form colleges, further education colleges and other educational facilities.
