Defence Estates has used a prime contracting system since 2001

This divides the UK into five regions, each run by a single contractor with the job of organising between 拢400m and 拢750m of work over a seven-year period. Alongside this is a 拢700m project to build the Defence Technical College in St Athan in the Vale of Glamorgan and the multibillion-pound SLAM programme for the renovation of forces housing, much of which is procured using the PFI. The Next Generation Estates Contracts frameworks will be used for everything up to 拢20m. Above that, alternatives will be considered and anything worth more than 拢50m will go out to competitive tender.
