The site will also include a public museum and a new base for the Royal Electrical and Mechanical Engineers.
Work has begun on a £121m Defence College of Technical Training at the former RAF Lyneham airbase.
It will provide training facilities for the three armed services at the base in Wiltshire which closed in 2012.
The start of work will be marked by a visit from Defence Minister Dr Andrew Murrison, who will take part in a turf turning ceremony later.
The work is the first stage of a £230m transformation of the airbase due to be completed by autumn 2015.
The development includes workshops, classrooms and labs, sports and welfare facilities and accommodation
Once completed, the new college will bring together technical training for the RAF, Army and the Navy.
There will be new accommodation blocks and teaching facilities, along with a large outdoor training area and a new base for the Royal Electrical and Mechanical Engineers.
Lyneham's history of repatriation will also be honoured with a publicly accessible public garden of remembrance.
At its peak the project is expected to employ 900 people with much of the work upgrading and refurbishing existing buildings.
The multi-million pound contract was awarded to Hercules - a joint venture between Kier Group and Balfour Beatty plc - in December.
