UK4 - Tender Notice
Summary of the contracting process

The Pirbright Institute is procuring a single-supplier works contract for a new fumigation lobby and dedicated air-handling unit (AHU) serving the ISO11 SAPO 4 animal facility. The scope covers detailed design, participation in a HAZOP study, design updates, factory construction and Factory Acceptance Testing, delivery, installation and site acceptance testing. The supplier must support operational qualification both before and after the equipment is returned inside the facility, manage its subcontractors and provide operation and maintenance documentation covering the work from design through completion. The equipment and associated works will be delivered and carried out at the Institute’s Pirbright Laboratory in Woking. The requirement combines specialist ventilation, air-conditioning installation, construction, design supervision, ventilation consultancy and fumigation-related work.

The procurement reached tender: the buyer invited offers through a below-threshold open competition. Electronic submission was allowed via the Institute’s procurement portal. The deadline for enquiries was 25 August 2026 at 4:00 pm, and the tender submission deadline was 15 September 2026 at noon. The contract period runs from 30 October 2026 to 30 September 2027. It is a single lot and the published estimated value is £151,666 excluding VAT, or £182,000 including VAT. The lot record gives the same numeric value with AED as its currency, while the overall tender value is in GBP. The award basis is set out in the Invitation to Tender pack. The procurement is for works and is below the applicable threshold.

This opportunity suits a principal contractor or specialist engineering business able to design, manufacture, install and qualify controlled-environment ventilation equipment for a high-containment animal facility. Bidders need capability in dedicated AHU systems, fumigation-lobby design and installation, construction coordination, factory and site acceptance testing, and operational qualification. Experience contributing to HAZOP studies and implementing their recommendations is relevant, as is the ability to produce complete operation and maintenance documentation. The successful supplier must take responsibility for managing all subcontractors involved in the works and coordinate installation within an area refurbished by others under a separate CDM construction arrangement. Suppliers should therefore have sufficient design, manufacturing, project-management and site-delivery capacity to manage the full sequence from factory build through final testing and handover.
