Monument record ORF 170 - Boiler House circa 1956

2007: Field survey of the Atomic Weapons Research Establishment by Historic England (S1).
Structure G3: The Boiler House was originally an L-shaped building with a double brick skin of fison Burwell whites. Former door ways are distinguishable by steel strip thresholds. Access to east-west range was by means of a single door in the northwest corner of the building, this range split into 2 rooms. In southwest corner are 6 pipes for cable routes, the pipes seem to be contemporary with the casting of the floor. Adjacent to the north wall is an infilled hole, it appears to be for cable routes but is evidently a secondary feature, directly next to this hole are 2 metal fixings set into the floor presumably for plant. In the southeast corner are 6 metal fixings for plant, probably for two different machines . In the central room are the foundations of three brick piers each one brick in width, the bricks are stamped ‘Fletton Limited’ and may represent a tank support. The southern bay is roughly divided into two by a brick partition wall, the bay to the east was entered through a double door on its south side. The western bay was entered from the south through a double door, marked by a metal strip. Internally is a rectangular blue engineering brick plinth and to its east small scar on the floor marks the position of another machine base. The eastern bay was originally entered through double doors in its north east corner, internally is a concrete machine plinth and to its west a partition wall, in the central bay are three further small machine beds these are in part built from LBC bricks.
