UK1 - Pipeline Notice
Summary of the contracting process

WM Trains Limited intends to procure works to deliver a Controlled Emission Toilet (CET) facility at Northampton depot. The scope falls within railway depot construction, railway construction and water-treatment work. The initial requirement is to support the depot’s CET project through the pre-construction stage, including the development of the detailed design and cost plan. The work is associated with Northampton and is being procured as a single package. It is relevant to contractors and specialist engineering businesses involved in railway depots, railway infrastructure, CET systems, water-treatment installations, construction planning and related design coordination. The buyer is WM Trains Limited, a public undertaking responsible for progressing this depot project.

This procurement is at the planning stage: WM Trains Limited has announced an intention to procure but has not yet invited tenders. The expected procedure is a competitive flexible procedure. The buyer expects the next notice to be published on 3 September 2026. The initial contract is planned to run from 4 January 2027 to 30 September 2027. It will begin with a Pre-Construction Agreement for GRIP Stage 5. After successful completion, the authority will assess the detailed design and cost plan and may negotiate a separate works contract covering GRIP Stages 6 to 8. Completion of the Pre-Construction Agreement does not guarantee that the later construction contract will be awarded. The single planned lot is identified as suitable for SMEs.

The work is likely to suit SMEs and established contractors with experience delivering railway depot construction, controlled emission toilet installations or water-treatment works. Suppliers able to manage pre-construction services, coordinate detailed design, develop reliable cost plans and support railway infrastructure projects should prepare for the market engagement and future tender stage. Relevant delivery capability will include understanding depot environments, integrating specialist systems into railway facilities and moving a project from GRIP Stage 5 towards later construction stages. Businesses with complementary design, engineering, construction and project-management teams may be well placed, particularly where they can demonstrate experience of complex rail or depot work. The later construction phase would be considered separately, so suppliers should distinguish their pre-construction capability from their ability to deliver the full works.
