## Summary

Science Museum Group is procuring works to design and install dehumidification systems for two stores—L&A and Radiation Stores—within a hangar at the Science + Innovation Park in Wroughton. The requirement is intended to control humidity and protect stored collections and materials. It includes heating, ventilation and air-conditioning equipment, ventilation and air-conditioning installation, and associated waterproofing work. This is a single works package managed by Science Museum Group, with delivery at the Wroughton park. Suppliers should therefore be able to provide an integrated dehumidification solution rather than standalone equipment, covering design, installation and the associated building and environmental-control works.

The procurement has reached tender: Science Museum Group invited offers through a below-threshold open competition, with electronic submission allowed. It has one lot. The enquiry deadline was 29 September 2026 at 5:00pm, and the tender submission deadline was 7 October 2026 at 4:00pm. The contract period is 15 October 2026 to 31 March 2027. The overall estimated value is £500,000 excluding VAT and £600,000 including VAT. The single lot is recorded as having the same amounts in AED. The award criteria are set out in the tender documents, so suppliers will need to review those documents for the detailed evaluation basis and requirements.

This opportunity suits contractors specialising in commercial dehumidification, HVAC, ventilation and environmental-control installations, particularly those able to take responsibility for both system design and on-site delivery. Relevant capability includes designing systems for enclosed storage environments, installing and commissioning ventilation or air-conditioning equipment, and coordinating associated waterproofing works. The requirement may also suit building-services contractors with the capacity to manage a complete package across technical design, construction activity and integration within an existing hangar. Firms with experience protecting museum, archive, laboratory or other sensitive stored materials may be well placed, as the works concern two specialist stores within a science and innovation facility. The tender documents will determine the precise technical and evaluation requirements.
