From these responses we will be selecting a shortlist of Contractors to issue an Invitation to Tender.
The project will install 2 district heat networks at Kingston Maurward College, Dorchester, which will use ground source heat pumps to replace the existing oil and LPG boilers as the source of heating and hot water.
The College has obtained a Government Public Sector Decarbonisation Scheme grant which requires that the project must be completed by 31st March 2022.

Interested parties are requested to respond to contracts@reenergisegroup.com by Friday 9th July 2021, indicating whether you will be submitting a full PQQ response.

Project Overview
The project is split into 2 districts and a ground array as follows:
1. Main District:
High temperature GSHPs with a total capacity of approximately 400kW will be required. These are to be located in a new prefabricated plant room, which will be sited on a slope and require a raised foundation slab. A new heat main (approx. length 500m) will connect the system to 13 existing heating systems (via heat exchangers) serving 19 buildings. The new district heating system will also provide heat to a Visitors Centre, which is currently heated with electric heaters.
As well as the plant room foundation, builders work will be required to clear structures and create an access road to the plant room.
Electrical power to the new plant room will be provided under a separate contract.
All existing oil / LPG plant will need to be removed from the plant rooms.

2. Glasshouses District:
High temperature GSHPs with an approximate capacity of 224kW are to be located in an existing plant room. A new heat main (approx. length 100m) will connect the system to provide heat to 5 glasshouses already supplied from the plant room, plus the nearby Gardener's Cottage, currently heated by a wood burner.
Builders work may be required to create plinths for the new plant; plus a foundation slab for the thermal store, which will be located outside the plant room.
Existing oil plant will need to be removed from the plant room serving the glasshouses.

3. Ground Array:
Both districts will be supplied from a single large ground array of approximately 120,000m2, to be installed in nearby fields within the College grounds. The flow and return pipes will require a road crossing.Timetable
