The requirement is a full turnkey solution, covering the accommodation and all services needed to deliver it. This is a construction and offsite-manufacturing requirement, classified under CPV 45223810 for prefabricated construction components. The facility is part of the Scottish Prison Service estate, and the buying organisation is also acting as a central purchasing body. The planned works are specifically for modular accommodation within the prison site, so relevant suppliers should be able to coordinate design, manufacture, construction, installation and associated delivery services as one integrated project rather than providing isolated construction products or services. The procurement is at the planning and discovery stage: the Scottish Prison Service has stated its intention to procure, but this record is not an invitation to tender. The expected route to market is the Government Commercial Agency Offsite Construction Solutions RM6184 Framework, Lot 4.1 Justice (3D Turnkey Solutions), with the requirement covered by the Government Procurement Agreement. An expression of interest has been issued to all named contractors on that framework. The buyer expects the next notice to be published on 2 November 2026; this is an indicative date, not a response deadline. The planned procurement is presented as a single requirement for the modular accommodation project, with selection and evaluation to take place through the chosen framework route. This will suit contractors able to deliver secure, justice-sector modular accommodation through a coordinated turnkey model. Strong candidates are likely to combine architectural and engineering design, offsite or volumetric manufacture, construction, transport, installation, commissioning and project management, with the capacity to manage these workstreams as an integrated delivery programme. Experience of prison, custodial, secure public-sector or similarly controlled environments would be directly relevant, as would the ability to work within an operational prison site and meet demanding requirements for safety, security, durability and compliance. At this stage, preparation is most relevant for contractors already named on Framework Lot 4.1: Justice (3D Turnkey Solutions), as the buyer has indicated that this framework will be its preferred market route. ## Notice SPS is in the discovery phase ahead of expected procurement to appoint a contractor to provide a full turnkey solution including all services required to deliver modular (prison cell) accommodation at HMP Castle Huntly. SPS has opted to utilise the Government Commercial Agency (GCA) (formally known as Crown Commercial Services CCS) Offsite Construction Solutions (RM6184) Framework Agreement Lot 4.1: Justice (3D Turnkey Solutions) as the preferred route to market. ### Lot Information Lot 1 SPS has now issued an Expression of Interest (EOI) via the Public Contracts Scotland Tender (PCS-T) Portal.
