IWM/2526/FM/3462: Ground Source Heat Pump in Hangar 4 at IWM Duxford
The submission route named on the official notice.
This sits in the lower-middle of the Construction band — a mid-scale opportunity. Based on 64,002 valued Construction tenders in our corpus.
Imperial War Museums (IWM) is seeking a qualified contractor to deliver the next phase of its low-carbon heating strategy at IWM Duxford.
This project involves the installation of a ground source heat pump (GSHP) system in Hangar 4, replacing the existing oil-fired boiler serving office areas on both the north and south sides of the hangar.
Phases 1 and 2 of IWM’s GSHP implementation have successfully covered Hangars 2, 3, 5, and Buildings 200 and 74.
Heat energy is sourced from underground water via bored holes on-site, transferred through plate heat exchangers in Building 68, and distributed via an ambient loop.
Phase 3 (the current tender) will connect to the existing ambient loop infrastructure already in place from previous phases.
The scope includes detailed design development (based on a novated preliminary design), procurement, installation, and commissioning of all associated plant and equipment.
A back-up electric boiler capable of meeting 100% of the heat load will also be integrated.
All equipment will be housed within the designated plantroom.
Access Code : 4E67D4UP37 This initiative supports IWM’s broader commitment to sustainability, energy efficiency, and climate action, aiming to reduce operational costs and set a benchmark for environmentally responsible practices in heritage and public sector buildings.
