## Summary

The public procurement process for the "Infrastructure Delivery Partnership (IDP)" was led by Sellafield Ltd, located in Whitehaven, GB. This contract focuses on delivering conventional infrastructure projects and tasks across several industry categories including construction, civil engineering, and consultancy services. Originally set with four Lots, only three Lots were awarded: Electrical Distribution Delivery Partner, Utilities Delivery Partner, and Civils Delivery Partner, with the Strategic Partner Lot being cancelled. The procurement was conducted using a selective method with a competitive procedure above threshold that included negotiation stages. The tender process commenced with a planned contract period starting from 10th October 2025 and ending on 10th October 2040. The contract, valued at approximately GBP 2.945 billion, was awarded on 10th October 2025, following the competitive negotiation process.

This infrastructure delivery contract presents significant opportunities for business growth, particularly for large companies engaged in engineering, construction, and consultancy services. With a substantial budget, businesses that specialise in quantity surveying, building installation, and project management consultancy services stand to benefit significantly. The extensive geographical reach including the UK, Europe, and other territories provides a wide market landscape. However, given the scale of the operation and the expertise required, this tender is less suited for small and medium enterprises (SMEs) and voluntary, community and social enterprises (VCSEs). The collaboration with experienced contractors like Morgan Sindall Construction & Infrastructure Ltd, Costain Limited, and HOCHTIEF UK further underscores the potential for major industry players to leverage this opportunity to expand their project portfolios and enhance their presence in the infrastructure sector.

## Notice

The Infrastructure Delivery Partnership will deliver conventional infrastructure projects and tasks. There are 3 Lots: Electrical Distribution Delivery Partner, Utilities Delivery Partner and Civils Delivery Partner. Delivery Partners will take the single viable option and complete detailed design and all procurement, installation, construction, commissioning and handover activities that form part of delivery. Note: When the procurement commenced there were originally 4 Lots, however, during the course of the procurement Lot 1 Strategic Partner was cancelled. This was in accordance with Sellafield Ltd.'s right to cancel a lot and not to award a contract as provided for at Section 11.9 of the Selection Questionnaire Instructions and also Section 6.6 of the Invitation to Submit Final Tender Instructions.
