Award Notice
Summary of the contracting process

The Environment Agency procured civil engineering consultancy services for the Thames 25-26 Modelling Package, covering hydraulic and integrated catchment modelling across three project areas. The work includes updating the existing Thames and Windrush hydraulic model, updating the Chil Brook hydraulic model, and building a new Colwell Brook hydraulic model. It also includes a new hydraulic model for Didcot, East Hagbourne and South Moreton, and an update to the existing Cole and Dorcan Brook integrated catchment model. Outputs for the Cole and Dorcan Brook work must separately represent fluvial and surface water flooding. Delivery is associated with the Reading area and the South East of England.

The procurement is complete and was awarded to WSP UK Ltd on 4 August 2026. The award value is £260,599.50, within an estimated overall range of £260,599.50 to £400,000. The contract runs from 1 July 2026 to 30 November 2028. The submission deadline was 6 January 2026 at 12 noon. This was a selective call-off from a framework agreement, rather than an open competition. The requirement was categorised as services and evaluated through the framework’s process. The Environment Agency is the buyer. The award is active, and the contract period is shared across the three modelling projects.

This award indicates demand for specialist flood-risk and catchment modelling capability within the Environment Agency, covering both river flooding and surface water flooding. A credible competitor would need to update and develop hydraulic or integrated catchment models, produce reliable one-dimensional and two-dimensional outputs, and work across multiple linked watercourses and communities. Relevant experience would include model construction, model updating, flood mechanism assessment and the clear separation of fluvial and surface water results. Suppliers able to manage several technical workstreams under a framework call-off, coordinate outputs for different locations, and provide civil engineering consultancy at this scale would be well placed for comparable requirements from this buyer. The procurement was identified as suitable for SMEs.
