This contract focuses on the services industry category, specifically targeting research and experimental development services related to buildings of historical or architectural interest. The procurement stage has now moved to the award phase following an open competition procedure below the threshold.

The survey operations will deploy from Lowestoft and conclude in Falmouth, with provisions for weather-related area adjustments, ensuring 24-hour operations aboard the RV Cefas Endeavour. This contract presents a significant opportunity for businesses specialising in marine geophysics and archaeological surveying, notably for SMEs such as Wessex Archaeology. The focus on high-quality services, with an emphasis on expert marine surveying and research, suits businesses that are keen to expand their expertise in government-sponsored marine archaeological projects. The open procurement method ensures a competitive environment for eligible bidders, providing avenues for expanding operations in niche historical research sectors through involvement in a collaborative, high-profile public project like this. Businesses looking to enhance their portfolios in governmental and historical research contexts will find this tender highly beneficial for growth and professional visibility. ## Notice The UK CSM Demonstration Survey is a major seabed survey that will take place in April-May 2026. It is a novel collaboration between public sector organisations to integrate respective survey activities under the umbrella of the UK Centre for Seabed Mapping (UK CSM). This tender is to commission suitably experienced marine archaeological geophysicists/surveyors to participate in the CSM Demonstration Survey on behalf of Historic England. The survey will be carried out aboard RV Cefas Endeavour. Survey operations will be carried out 24 hours; HE-commissioned geophysicists/surveyors will operate a single 12-hour shift. Accommodation and subsistence will be provided aboard. Options are being maintained for different survey areas to allow for weather. The survey vessel will mobilise at Lowestoft and demobilise at Falmouth. Crew change will occur at Lowestoft or Falmouth. Other than the crew change, the vessel is not expected to return to port during each leg of the survey. Historic England's requirement is for one geophysicist/surveyor to participate in each leg of the survey. Tenderers can bid for either one or for both survey legs. Historic England's preference is to commission one contractor to cover both legs but reserves the right to commission one contractor for each leg. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/025023-2026 | | Notice type | UK7 - Contract Details Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Below threshold - open competition | | Tender suitability | Not specified | | Awardee scale | SME | | All stages | Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 19 Mar 2026 | | Submission deadline | 6 Mar 2026 | | Future notice date | Not specified | | Award date | 17 Mar 2026 | | Contract period | 20 Mar 2026 - 31 Jul 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £29,000 | | Lots value | £29,000 | | Awards value | Not specified | | Contracts value | £27,946 | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Active | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | HISTORIC ENGLAND | | Locality | SWINDON | | Post town | Swindon | | Postcode | SN2 2EH | | Country | England | | ITL 1 | TLK South West (England) | | ITL 2 | TLK7 Gloucestershire and Wiltshire | | ITL 3 | TLK71 Swindon | | Local authority | Swindon | | Electoral ward | Mannington and Western | | Westminster constituency | Swindon South | | Delivery location | Not specified | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | WESSEX ARCHAEOLOGY | ## CPV Codes ### Divisions - 45 - Construction work - 73 - Research and development services and related consultancy services ### Codes - 45212350 - Buildings of particular historical or architectural interest - 73100000 - Research and experimental development services ## Release History - 19 Mar 2026 at 10:41 - Award - UK7 - Contract Details Notice - https://www.find-tender.service.gov.uk/Notice/025023-2026 - 13 Feb 2026 at 15:51 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/013566-2026 - 13 Feb 2026 at 14:11 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/013465-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/025023-2026 19th March 2026 - Contract details notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/013566-2026 13th February 2026 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/013465-2026 13th February 2026 - Tender notice on Find a Tender ## Notice URLs - http://www.historicengland.org.uk - http://www.wessexarch.co.uk - https://in-tendhost.co.uk/historicengland/aspx/Home - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
