Summary of the contracting process

Wiltshire Council is procuring construction work for a new Strategic Central Depot at Bowerhill, Melksham. The single depot will rationalise and modernise the Council’s operational estate by bringing together Highways, Waste, Streetscene and Fleet services. The development includes operational yards, vehicle stabling, HGV and LGV maintenance workshops, offices and welfare facilities, a Household Waste Recycling Centre, fuelling and washdown facilities, and material storage areas. The site must accommodate vehicles up to 32 tonnes, public-facing areas and future fleet electrification. Design and construction must work around continuing highways, waste and recycling operations, with segregated movements and phased delivery. The scheme targets BREEAM Excellent and includes low-carbon energy measures such as air-source heat pumps and photovoltaics. Work will be delivered in Bowerhill, Melksham.

The procurement has reached tender: Wiltshire Council invited suppliers to participate through a selective competitive flexible procedure. It is a single-lot Design and Build appointment, seeking one contractor. Suppliers must submit requests to participate by 12:00 on 24 September 2026; enquiries close at 12:00 on 7 September 2026. The Council will assess pass/fail and scored participation questions, shortlist between one and four candidates, then invite shortlisted suppliers to tender. The award decision is due by 17 March 2027. The contract is scheduled to run from 12 April 2027 to 31 December 2028. Its estimated value is £20 million excluding VAT, or £24 million including VAT. Evaluation is 60% financial and 40% quality. Electronic submissions in English are allowed via the Supplying the South West portal, where registration is required. The contract uses NEC Option C PSC and ECC terms.

This opportunity suits a principal contractor able to take single-point responsibility for the design and construction of a complex operational depot. Relevant capability includes civil engineering, commercial and industrial building construction, operational yards, heavy-vehicle stabling and maintenance facilities, waste-recycling infrastructure, fuelling and washdown systems, offices and welfare accommodation. Suppliers should be able to plan and deliver safely on a live site while maintaining 24/7 highways response and daily public access to recycling facilities. Strong phasing, logistics, traffic segregation and stakeholder-management experience will be important. The work also favours contractors with expertise in ground, drainage, ecology and biodiversity net gain, radiological risk investigation, resilient infrastructure and low-carbon design. Experience delivering BREEAM Excellent schemes and facilities prepared for fleet electrification will be relevant, alongside the capacity to manage a substantial NEC design-and-build contract.

Planning Information

Wiltshire Council is progressing the development of a new Strategic Central Depot at Bowerhill, Melksham, forming part of a wider programme to rationalise and modernise the Council’s operational estate. The depot will consolidate multiple existing facilities and services, including Highways, Waste, Streetscene and Fleet operations, into a single multi-functional site The development is intending to be delivered on a live operational site, with existing Highways and Household Waste Recycling Centre functions to remain active throughout the design and construction phases. These operations include 24/7 highways response capability and daily public access to the HWRC, requiring careful planning, segregation and continuity of service at all times. The scheme is comprised of a complex mix of facilities, including operational yards, extensive vehicle stabling, maintenance workshops (supporting HGV and LGV fleets), office and welfare accommodation, HWRC infrastructure, fuelling and washdown facilities, and significant material storage areas. The site must support a wide range of vehicle types (up to 32t) and high operational areas, including public interface areas and future adaptability for fleet electrification. Several key constraints will influence design and delivery, including: • Live operational environment and phasing requirements • Site covenants restricting development in parts of the former golf course • Ground, ecological and drainage considerations, including biodiversity net gain • Identified radiological risk requiring further investigation and specialist input prior to intrusive works • Complex access arrangements and the need to segregate public, contractor and operational movements The development is targeting BREEAM ‘Excellent’ and aligns with Wiltshire Council’s net zero ambitions, requiring a fabric-first approach, low-carbon energy strategies (including air source heat pumps and photovoltaics), and infrastructure that supports future operational flexibility and resilience. Procurement options under consideration include both single-contractor and dual-contractor approaches (separating civils and building works), under standard forms of contract such as NEC, ICC and JCT. Wiltshire Council intends to hold a Soft Market Testing (SMT) engagement exercise webinar at 13:30 on the 23rd April 2026 on Microsoft Teams. This exercise is intended to inform the Council’s approach and does not constitute a call for competition. A formal procurement process will follow in due course. Any suppliers interested in attending should express an interest via email to CentralDepotProject@wiltshire.gov.uk and they will receive further information regarding the event details. Should you be interested in attending the event please express your interest by emailing names, roles, and contact details to the above-mentioned e-mail address by no later than 12:00 22nd April 2026 . Yours Faithfully Wiltshire Council
