## Summary

Nuclear Restoration Services Limited, located in Warrington, is carrying out a direct award for civil consultancy support related to the Shaft and Silo Advanced Transition Works at its facility. The procurement involves the provision of Civil, Structural, and Architectural consultancy services to support various construction phases, including the Shaft Headworks and the Advanced Transition Works. The procurement process is in its award stage, with key details finalised on 25th March 2026. The contract spans from 24th March 2026 to 24th August 2028. This project falls under the public authority category within sub-central government, with the procurement method being direct award due to technical complexities and safety risks associated with design integration.

This tender presents significant opportunities for entities with expertise in civil and structural engineering consultancy, particularly those experienced in handling complex technical queries during construction phases. Businesses adept at providing reinforced concrete detailing, construction phase design interpretation, and technical documentation updates will find this contract suitable. The involvement of Sanderson Watts Associates Limited as the awarded supplier underscores the value of continuity in consultancy services, thus enhancing the attractiveness for businesses looking to sustain growth in advanced technical consultancy, especially in nuclear restoration projects. Organisations with capabilities to integrate designs collaboratively with other technical disciplines and navigate the nuances of temporary works and risk management would stand to benefit significantly from their contribution to this project.

## Notice

Provision of Civil, Structural and Architectural (CS&A) consultancy services in support of the Advanced Transition Works (ATW) at the Shaft and Silo facility. The scope includes technical support to ATW Construction Phase 2, the Shaft Headworks and ATW Construction Phase 3. The scope includes technical support for reinforced concrete detailing, construction phase design interpretation, resolution of site queries, temporary works design, and integration of learning from previous phases. The Consultant will also provide updated design documentation, attend project meetings, and support the planning and implementation of future construction phases including Shaft Headworks and ATW Phase 3.

### Procurement Information

The consultant developed the detailed design and build to print drawings for the advanced transition works. During the construction phase the consultant is required to be available to respond to technical queries that may arise on their design. To potentially appoint another consultant at this stage may inadvertently introduce design safety risks as they would not be aware of the original design intent or have been involved in the complex design integration with mechanical and electrical designers. There would also be a disproportionate mobilisation period and knowledge transfer from the incumbent to the potentially new contractor that would outweigh any perceived commercial benefits.
