Situated at Culham Science Centre in Abingdon, UK, the procurement falls under the 'services' category, specifically targeting feasibility studies, advisory services, and engineering designs related to HVAC systems. This planned procurement, published under the regulations of the Procurement Act 2023, invites interested suppliers to register on the UKFE Delta portal by 15th September 2026, with the project execution running from 24th September to 14th December 2026, and an optional extension available. The procurement method employed is an open competition under the below-threshold category. This procurement presents a substantial opportunity for businesses involved in feasibility studies, HVAC systems, and engineering design services. Companies specialising in these areas, particularly those focused on mechanical and electrical installations for buildings and ventilation consultancy services, are well-suited to compete. With a contract valued at £70,000 (gross amount £84,000), this tender provides an avenue for growth, especially for small and medium-sized enterprises (SMEs) as it highlights a suitability preference for them. Engaging in such a project not only offers financial benefits but also allows businesses to establish a relationship with a prominent government entity aiming at cutting-edge energy solutions. ## Notice The purpose of this Task Order will be to produce a concept-level Heating, Ventilation and Air Conditioning (HVAC) study to support the ongoing development of the Spherical Tokamak for Energy Production (STEP) prototype fusion facility, together with its associated maintenance, handling, and supporting infrastructure. The study shall provide the technical basis for the development of the facility HVAC architecture and ventilation strategy and shall inform the wider Tokamak Building design. The outputs of the study shall support the development of the building layout, contamination control strategy, nuclear ventilation philosophy, and the preparation of a Rough Order of Magnitude (ROM) cost estimate for the HVAC plant and associated systems.
