Both NERC and BGS form a part of the UK Research and Innovation (UKRI). The tender is for the procurement of a supplier to provide the design and build support to BGS (the Client) in delivery of the geothermal infrastructure for the Glasgow Observatory. The Contractor's main responsibilities will include but are not limited to: detailed design and construction of the works; testing and commissioning the works. The supplier shall be appointed under an NEC4 ECC. The deadline for submission of tenders was 04 June 2021 (14:00 BST). Additional information: UKRI wishes to establish a contract for design and and build of geothermal infrastructure for the UK Geoenergy Glasgow Observatory. The Contractor will develop the 'Detailed Design Specification' through collaboration with the Client, to deliver an engineering design for the bespoke research infrastructure that meets the science requirements within the specified budget. Assuming the design is accepted, the Contractor will build the design such that the facility is 'research-ready'.The geothermal infrastructure will comprise (but may not be limited to) the following: 1.Extend four of the mine-water borehole wellheads above ground level and construct a low brick wellhead chamber or similar and associated pipework. 2.To complete the hydraulic and thermal design of a pumping main and reinjection main, associated manual valve work and other infrastructure. To excavate and install this pipe infrastructure in trenches. 3.To install a cable duct within the main pipework trench to be routed to a control panel at a heat centre at Site 1. 4.To select and install an electrical submersible pump, associated cabling and rising main in boreholes GGA05 and GGA07. Consideration should be given to the termination and support of these items through the upper wellhead flanged plate. A suitable valve arrangement and wellhead sensors are also to be incorporated into the design. 5.To design and install a reinjection main in boreholes GGA01 and GGA08, with a corresponding pressure-tight wellhead upper-flanged plate. A suitable valve arrangement and wellhead sensors are also to be incorporated into the design. 6.To install two access tubes in all four boreholes, one of which shall be installed with a sensor to determine and log downhole water head, temperature and electrical conductivity. 7.The well equipment and pipework shall be selected to deliver a variable flow rate up to a maximum of 12 L/s and down to a minimum of 3 L/s, while maintaining a positive gauge pressure of at least 1 bar throughout the entire pumping-heat exchange-reinjection main system. 8.The wellhead flange plates should be designed to accommodate both a reinjection main and a pump rising main in the future. 9.To select and install a "heat centre" within the Site 1 compound. 10.To select and install a reversible water-air chiller / heat pump adjacent to the heat centre, with a nominal maximum output of 200 kW in both heating and cooling mode. 11.To design and install a heat exchanger circuit in the heat centre. The circuit should have a combined heat exchange capacity of 200 kW, provisionally envisaged to be three equally-sized shell and tube or plate heat exchangers. 12.To design and install an insulated heat transfer fluid circuit connecting the heat exchangers to the heat pump / chiller unit, with temperature and pressure sensors, circulation pump, glycol pressure regulation and top-up equipment, any necessary thermal buffering, and a sampling tap for sampling the glycol. 13.To install monitoring equipment within the heat centre on the mine water circuit to include an electromagnetic flowmeter, chemical dosing pump, temperature, pressure and electrical conductivity sensors, and a sampling tap. 14.To equip the heat centre with a control panel / management system for receiving and logging signals from the various installed sensors, and also sending control signals to the submersible pumps and the heat pump/chiller. 15.To prepare full design, installation, operation and maintenance documentation for the infrastructure installed in this Contract. 16.To prepare a maintenance schedule for the facility. 17.Commission, test and demonstrate the facility. 18.To providing training on operating the system Read full description ## CPV classification Construction project management services Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/06351561-8e1e-4598-91fd-34c1e1015e5a) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
