The requirement is for a design-and-build solution, covering the design and physical replacement of hinges on prison cell windows. The work will be delivered at HMP Perth in Perth, Scotland. Scottish Prison Service is both the buying organisation and the central purchasing body. The main classification is window installation work (CPV 45421110), with related classifications covering building joinery, doors, windows and associated installation services. This is a specialist prison-estate works requirement rather than a general supply contract, and is suited to contractors able to plan and deliver window-hardware replacement within an operational custodial site. The procurement reached the tender stage: the Scottish Prison Service invited offers through a single-lot open procedure, with electronic submission. Tender responses were to be evaluated in accordance with the Invitation to Tender, supported by economic and technical selection criteria. The tender submission deadline set by the buyer was 23 September 2026 at 14:00. Bid opening and the start of the award period were scheduled for 23 September 2026 at 14:30. The contract period is 21 October 2026 to 31 March 2027. Bids must remain valid until 16 December 2026. English is the submission language. Electronic payment and electronic ordering will be used, and electronic invoicing is allowed. Variants are not permitted, and the contract has no stated renewal or extension option. This opportunity suits building-works contractors, window and door specialists, joinery firms and contractors experienced in designing and installing replacement hinges or related window hardware. The design-and-build format favours a supplier able to take responsibility for the solution as well as the installation, including coordinating design, materials, site activities and completion. Experience working safely and reliably in a prison or similarly controlled public-sector environment would be relevant, given that the work concerns cell windows at HMP Perth. Competitors should be prepared to demonstrate both economic standing and technical suitability, and to manage a focused programme of works within the stated contract period. The requirement is a single phase of a wider hinge-replacement programme, so delivery discipline and practical site capacity will be important. ## Notice SPS requires a contractor for a design and build solution for the replacement of cell window hinges at HMP Perth.
