We were asked by a nuclear facilities management company at Sizewell to supply them with a changing room facility to be partly fabricated in our depot and the assembled on-site. The changing room was built using 4 x 40ft containers cut to 30ft placed in a 2×2 configuration to create a large changing room, storage, and office space.
Once delivered to Sizewell the containers were assembled on-site and are now used to allow personnel to move between different areas of the reactor building safely as well as providing better storage and office space than the previous facility.
The specification was a follows:
