## Summary

The public procurement process initiates with a planning stage spearheaded by Great British Energy - Nuclear, a sub-central government public authority based in London. The procurement, titled "prj_6641 - GBE-N Engineering Partner," focuses on architectural, construction, engineering, and inspection services. Planned within the framework of UK legal basis 2023/54, this tender primarily addresses the engineering design for a Small Modular Reactor (SMR) project, extending from concept design through to the operational phase, as indicated by RIBA Stage 7. Key dates include the anticipated future notice date on 7th September 2026, with the contract period expected to commence on 27th November 2027 and conclude on 27th January 2042. The projected contract value is between £200 million and £400 million.

This tender provides a pivotal opportunity for businesses in the engineering and design sectors, particularly those specialising in large-scale civil projects and nuclear engineering. It offers a substantial, long-term engagement opportunity that could significantly contribute to business growth. Companies with a strong track record in managing complex engineering designs and those capable of integrating innovative solutions into established frameworks are well-suited to compete for this contract. Establishing a partnership with Great British Energy - Nuclear could open avenues for strategic alliances and enhance a firm’s portfolio in the nuclear energy domain.

## Notice

This work package encompasses the engineering capability to progress the concept design produced by the Foundation Engineer (FENG) at the end of RIBA Stage 2 and to continue the development of the design for site works through RIBA Stages 3 (Spatial Planning) and 4 (Technical Design) throughout the entire lifecycle of the Small Modular Reactor (SMR) project through to and inclusive of RIBA Stage 7 (Use). The Engineering Partner will also be required to undertake works associated with any additional RIBA Stages (from RIBA Stage 0 through to RIBA Stage 7) for any emerging scope that arises over the lifecycle of the SMR Project and will be required to support with the ongoing management of design change/control. The Engineering Partner contract is estimated to be valued between PS200m - PS400m *The positions and timelines presented are based on current information and assumptions.
