UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Slough Borough Council is developing the Granville Flood Alleviation Scheme, also known as Project Sponge. The planned procurement is for civil engineering and construction works to reduce flood risk, covering site preparation, structural works, river regulation and flood control, riverbank protection, flood-defence maintenance, drainage and surface-water works, and dredging and pumping. The work is classified mainly as construction works and is intended for delivery in the Granville scheme area in Slough. The council’s preliminary market engagement aims to identify more organisations and a wider range of suppliers that may be interested in tendering for the project. This is relevant to civil engineering contractors, flood-defence specialists, drainage and water-management companies, river engineering firms, and businesses able to deliver associated construction and maintenance works.

This procurement is at the planning stage: Slough Borough Council has stated an intention to procure but has not invited tenders. The council expects to publish the next notice on 19 October 2026. It has scheduled preliminary market engagement, with the engagement milestone due on 18 September 2026. The planned contract period is expected to run from 2 November 2026 to 26 February 2027. The procurement is arranged as one lot, currently in planning, and the council has indicated that the requirement is suitable for small and medium-sized enterprises. The engagement is intended to inform the council about the potential supplier market and increase the number and types of organisations that could be interested when the project reaches the tendering stage.

The work should suit contractors with practical experience in flood alleviation, flood-defence construction or maintenance, drainage infrastructure, river regulation, riverbank protection, dredging, pumping and related civil engineering. Firms able to combine siteworks, structural construction and water-management expertise may be well placed to respond to the eventual requirement. The single-lot structure presents a route for an integrated contractor, while the stated SME suitability indicates that smaller specialist businesses may also be relevant, either independently or through collaboration with other firms. Businesses with recent experience delivering construction works in or around watercourses, managing flood-risk assets, protecting riverbanks or installing drainage and surface-water infrastructure should use the engagement phase to explain their capabilities and how they could contribute to the scheme.
