Replacement of the Offices Chiller Plant and Associated Works at Bristol & Bath Science Park – Emersons Green.

The Council intends to appoint a suitably qualified Mechanical and Electrical Contractor to act as Principal Contractor for the design, supply, installation, testing, and commissioning of replacement office chiller plant with associated mechanical, electrical and building works at The Bristol & Bath Science Park, Emersons Green. The works are programmed for delivery during 2027, with all works to be completed and the installation fully operational by 25 June 2027. The Council commissioned an engineering consultant to undertake an assessment of the existing office chiller plant to verify that its installed capacity remains appropriate for the building's cooling demand.

The assessment concluded that the existing chillers are adequately sized, and consequently the replacement chillers will be designed and selected to provide an equivalent cooling duty and performance. The appointed Contractor shall be required to demonstrate a proven track record in delivering projects of a similar nature, scale, value, and programme, together with the organisational capacity and financial resilience necessary to fulfil the Contract. The Council will not accept proposals whereby the entirety of the works is subcontracted.

The Principal Contractor must maintain direct control over the delivery of the principal work packages and remain fully responsible for the effective management, coordination, and performance of all specialist subcontractors engaged in the execution of the works. The Contractor shall provide evidence that it maintains industry-recognised third-party accreditation appropriate to the proposed works. As a minimum, the Contractor shall: Hold current REFCOM company registration (or equivalent certification for refrigerant management).

Employ operatives and supervisors holding relevant F-Gas qualifications in compliance with current legislation.
