Summary of the contracting process

The Defence Science and Technology Laboratory (Dstl) bought minor mechanical and electrical (M&E) and civil construction works across its estate. The requirement covers construction work delivered under an NEC4 Term Service Contract, indicating a continuing programme of building, engineering, repair and associated estate works rather than a single standalone project. The named delivery location is Dstl’s estate at Porton Down, Salisbury. This is a works opportunity for contractors able to combine building and civil engineering capability with mechanical and electrical services, and to manage varied minor works for a central government science and technology organisation. The procurement is centred on construction delivery and estate maintenance activity, rather than the supply of goods or consultancy services.

The procurement is complete and the contract was awarded directly without competition under a below-threshold procedure. It had one completed lot. The award was made on 20 August 2026 to CONCEPT BUILDING SERVICES (SOUTHERN) LTD. The awarded value is £3,000,000 excluding VAT and £3,600,000 including VAT. The contract was signed on 3 September 2026 and runs from 3 September 2026 to 2 September 2029. Two optional 12-month extension periods are provided, giving a maximum possible end date of 2 September 2031. The contract is active and the award is active. The stated procurement method was direct award without competition; no competitive evaluation basis is recorded.

This procurement demonstrates established demand from Dstl for a broad minor-works contractor able to support an operational public-sector estate. A credible future competitor would need practical M&E and civil construction capability, with sufficient capacity to handle a varied programme of tasks rather than one defined build. Experience of working under NEC4 Term Service Contract arrangements would be important, including managing instructions, programme changes, pricing, records, quality and client reporting within a term-service model. Contractors should also be able to coordinate multiple trades and maintain reliable delivery at a secure science and technology site in Salisbury. The selected supplier’s profile indicates that Dstl placed the requirement with a large construction business, so comparable organisational capacity and estate-works experience would strengthen a future proposition.
