Synchrotron Roof Replacement
Diamond Light Source is the UK’s national synchrotron science facility, located at the Harwell Science and Innovation Campus in Oxfordshire. The synchrotron building is the circular building which accommodates the storage ring and beamlines. The existing roof is an aluminium standing seam roof system, which is starting to deteriorate due to thermal movement. The total roof area is approximately 32 000 m2 and comprises of 96 bays. Each bay includes both parallel and welded tapered sheets, which provides the facet to give the building its circular shape.
Diamond plans to replace the existing aluminium standing seam roof to the synchrotron building with a new single ply membrane together with solar photovoltaic cells.
Diamond light source is looking to appoint a suitable principal contractor (PC) to undertake the works under the NEC3 design and build form of contract. The contractor can either be a roofing contractor who is able to undertake the principal contractor duties (as defined under the construction (Design and Management) regulations 2015) or a general/main contractor who will undertake the PC role and subcontract the roof works to a specialist roofing contractor (either in-house or externally).
