Contract to design, build, operate and maintain the South Kilburn District Heat Network - (RESID-2324-005)

The Council is seeking a contractor to design, build, operate and maintain the ‘South Kilburn District Heat Network’ (SKDHN) to serve the South Kilburn regeneration area. SKDHN will be fully owned by the Authority. The Authority will own the heat generating plant and distributing network to the heat exchangers. The Initial Works will be followed by the Additional Works as set out in Appendix 2 of the ITPD (Specification) and defined in Clause 1 (Definitions and Interpretation) of the South Kilburn DHN Agreement.
The term of contract includes fifteen years operation period with the ability for the Authority to extend for an additional period up to 10 years.

London Borough of Brent (the Authority) is seeking a contractor to design, build, maintain and operate the ‘South Kilburn District Heat Network’ (SKDHN) to serve the South Kilburn regeneration area. The SKDHN will sell heat to public sector third parties, subject to Public Contracts Regulations 2015 or other procurement legislation as may be in force. SKDHN will be fully owned by the Authority.
Heat will be supplied from an energy centre located in Unity Place, situated on the corner of Cambridge Road and Carlton Vale. The energy centre shall supply heat via a combination of air source heat pumps (ASHPs) on the building roof, with peak and reserve boilers, distribution pumps and thermal storage in the building basement. These ASHPs will provide low carbon and affordable heat to reduce reliance on fossil fuels and will supply heat to ~800 dwellings, a school and multiple commercial buildings.
Additional ASHPs are required as the network expands and are to be located on the roof of the planned Hereford and Exeter building. The network includes a number of planned developments as well as existing buildings.
The Authority is seeking to appoint a suitably qualified and experienced contractor to design, build, operate and maintain the SKDHN via a Design, Build, Operation and Maintenance Contract. The energy centre will be in an existing building that was constructed in circa 2021 as part of a new housing development. The Works shall include the design and fit out of the existing lower basement energy centre and design and installation of rooftop ASHP plant solution, the design and build of the heat network and the heat connections within the connecting buildings, and the operation and maintenance of the completed heat network including metering of customers’ demands.
The Contractor is being employed as a competent civils, mechanical, electrical, controls, maintenance, and metering contractor for the Works (it should be noted that heat billing will be conducted in house by the Authority using the metered data collected by the Contractor). The Contractor is required to execute the works to provide a safe, cost-effective, high-quality installation compliant with all prevailing good industry practice, regulations and statutory requirements and in accordance with all tender drawings and specifications. The design, installation and operation of the heat network shall be fully compliant with CP 1 (2020) The Heat Network Code of Practice for the UK and have a carbon intensity of less than 100gr/kWh, which are mandatory requirements, among others, for the grant funding awarded by the Green Heat Network Fund (GHNF) for the project.
The detailed design and specification in relation to the "Initial Works" (Phase 1) is set out in Appendix 2 of the ITPD (Specification). All associated drawings and documents are included within the Procurement Pack.
A summary of works for the Phase 1 SKDHN comprise:
• RIBA 4 design and installation of the heat network energy centre fit out. This energy centre is located within the existing basement plant room in Unity Place.
• RIBA 4 design and installation of externally mounted ASHP plant on the roof of Unity Place, and the roof of Hereford and Exeter
• RIBA 4 design and installation of thermal substations within the connecting buildings, and the design and installation of a buried heat network.
• The operation, maintenance, heat metering services and to provide data to the Authority for monitoring KPIs of network performance and for billing customers.
There is limited information currently available from developers for the buildings to be connected beyond Phase 1. These are Phases 2-4 of the project and detailed further within document S2002-"SEL-ZZ-XX-SP-Z-0001 Main Contractor Scope of Work". The Contract will include a procedure for agreeing the detail in relation to any works required following the Initial Works (Additional Works). Any references to "phases" contained in the documents provided to Bidders is for convenience only and does not represent the structure of the Project; these references should be interpreted in line with the above i.e. Initial Works and Additional Works, as set out in the Contract.
