This open procurement process is at the tender stage, with submissions due by 10 December 2020. The contract is set to commence on 1 March 2021 and will run until 30 June 2022. The work involves the manufacture, assembly, testing, inspection, and transport of shielding lids and location frames intended for the European Spallation Source (ESS) in Lund, Sweden. Interested suppliers should note that delivery addresses include various locations such as the United Kingdom, Europe, and British Overseas Territories.

This tender presents significant opportunities for businesses, especially those with expertise in heavy manufacturing, structural engineering, and assembly of complex steel and concrete installations. Companies that can demonstrate capabilities in producing robust, large-scale construction components and meeting stringent quality standards will be particularly well-suited to compete. Small and medium-sized enterprises (SMEs) are encouraged to participate, as this contract may offer substantial avenues for growth and collaboration within the scientific infrastructure sector.

## Notice

This UK Atomic Energy Authority has a requirement for the manufacturing, assembly, testing, inspection and transport for shielding lids and their corresponding location frames under a 'build to print' contract, to be used in the European Spallation Source (ESS) in Lund, Sweden. Each Pit Lid is constructed from high density reinforced concrete, encased in an 8mm welded stainless steel shell. The Pit Lids each have some variation in shape and size, with weights in the region of 15-25t. The exterior plates form a labyrinth design, that attenuates radiation. There are also 5 location frames to be constructed, from stainless steel angle bar, which also include location features. These frames are to be installed within the pit surround to form a base upon which a set of Pit Lids are placed. The contract dates detailed within this notice are estimated and may be subject to change.
