## Summary

The Oil and Pipelines Agency intends to procure a design-and-build contract for underground storage caverns. The work combines construction and engineering activity with drilling services, covering the development and delivery of underground storage infrastructure rather than the supply of standalone equipment. It is classified primarily as works, with services also included, and falls within the defence and security regime. The procurement is associated with the agency’s Plumley Strategy 2 project. Suppliers should expect the requirement to involve integrated design responsibility, construction delivery and specialist subsurface or drilling capability. Businesses operating in underground construction, cavern development, geotechnical engineering, drilling or related infrastructure delivery may find the scope relevant when the procurement reaches the market.

This process is at the planning stage: the Oil and Pipelines Agency has stated an intention to procure, but has not issued an invitation to tender. The buyer expects to use an open procedure under the Procurement Act 2023, for a single planned lot. The estimated contract value is £6,000,000 excluding VAT, or £7,200,000 including VAT. The anticipated contract period is 1 April 2027 to 31 March 2031. The buyer expects the next notice to be published on 30 October 2026. The procurement is above the relevant threshold and is subject to the defence and security regime. The stated requirement is for a design-and-build contract covering underground storage caverns, with engineering works, construction works and drilling services.

This requirement is likely to suit contractors able to take responsibility for both design and construction of complex underground infrastructure. Relevant businesses may include civil engineering and construction firms, specialist underground works contractors, cavern developers, drilling companies, geotechnical engineering practices and organisations able to combine these capabilities through a delivery partnership or supply chain. Experience in subsurface construction, drilling operations, engineering design and the delivery of major infrastructure will be commercially relevant. Because the procurement falls within the defence and security regime, suppliers should prepare to demonstrate that they can operate in a security-sensitive public sector environment and meet the associated contractual, organisational and technical requirements. Early preparation should focus on capability, capacity and suitable delivery partners.
