## Summary

The procurement process, initiated by Nuclear Waste Services, focuses on the long-term performance monitoring of a gas vent. The project falls under the 'Environmental monitoring other than for construction' category and is located across various regions including the United Kingdom, European territories, and others. Described as a selective procurement via a call-off from a framework agreement, the process has advanced to the award stage, with Quintessa Limited being the awarded supplier. The contract period spans from 9th May 2025 to 30th June 2025, with the procurement valued at £24,664.68. The tender period concluded on 25th April 2025.

This tender presents significant opportunities for businesses specialising in environmental services, particularly those with capabilities in managing long-term monitoring projects. Small and medium-sized enterprises (SMEs) would find this project particularly suitable given the selective procurement method favouring such organisations. Engaging in this contract can aid businesses in showcasing their expertise in environmental monitoring and potentially foster relationships with key governmental departments, which could lead to future opportunities in public sector projects.

## Notice

The objective of this project is to extend the current EPA to consider explicitly the evolution of the gas vent, as currently planned within the final cap, over the 5000-year timescale of interest using a consistent, but proportionate approach.
