## Summary

The procurement process concerns the Defra Network eTendering Portal, which has awarded a contract for the "Surface Water Impact Modelling (STA)" project. This project, classified under research services, aims to model the impacts of extreme surface water flood events on populations, properties, and infrastructure. The contract was awarded on 1st March 2018, with a total value of £23,480. The contract is set to run until 31st August 2018. Interested parties were invited to participate in a limited procurement method, negotiated without a call for competition, with the tender period having concluded on 28th February 2018. The geographical delivery for this project includes the United Kingdom as well as British Overseas Territories and Europe.

This tender presents opportunities for businesses specialising in research and modelling services, particularly those equipped to handle environmental and risk assessment projects. Small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) are encouraged to consider similar upcoming tenders. Firms with expertise in hydrological modelling and flood impact studies would be particularly well-positioned to compete, expanding their client base through government contracts and potentially enhancing their service offerings in related fields.

## Notice

The aim of the project is to estimate the impacts on population, property and infrastructure of a realistic worst case scenario surface water flood event, using existing and up-to-date modelling and data. This would involve applying a 20-30% uplift to the rainfall inputs used in the London-centric South West scenario to produce a new, more extreme surface water scenario. The previously-developed hydraulic models would be re-run using these uplifted rainfall inputs and the outputs mapped/supplied as previously. Additional information: Please note that Defra procurement uses an E-tendering system for Procurement activities. This is currently provided by Bravo Solutions.
