This tender, titled "Contract for the Preliminary Contamination Risk Assessments," falls under the industry category of site-investigation services, with additional classifications including ground and pollution investigation work. It is an open procedure targeting SMEs, and is situated in the North West of the United Kingdom. The tender was published on 14 November 2025, with a tender period ending on 16 February 2026, and the contract period scheduled from 30 March 2026 to 18 September 2026. This tender presents an excellent opportunity for businesses specialising in land condition assessments, particularly those with expertise in ground investigation and contamination analysis. Companies operating within the environmental services sector and having experience with chemical and oil pollution investigations will find this opportunity highly suitable. The open procurement method favours small and medium enterprises, offering a platform for these businesses to expand their portfolio within public sector projects. Participating in such initiatives not only increases business visibility but also contributes to environmental safety and compliance, leveraging technical expertise to meet contractual obligations efficiently. ## Notice Merseyside Waste Disposal Authority (MWDA) is inviting tenders from suitably qualified, experienced and registered Specialist in Land Condition (SiLC) ground investigation contractors to undertake Preliminary Contamination Risk Assessments at several of the Authority's operational waste management facilities. MWDA's long-term waste management contract, the Waste Management and Recycling Contract (WMRC), expires in 2034 and there are a number of contractual obligations required to be undertaken prior to the expiry of the Contract. This includes a determination if any ground contamination has occurred during the life of the contract. The sites that form MWDA's operational estate were leased to the WMRC Contractor upon its commencement in 2009. The Authority wishes to employ a suitably qualified and experienced contractor to determine and assess the potential for, or presence of, contamination associated with the operations carried out during the contractual term of the WMRC. The Authority wishes to undertake this work in two distinct phases. First, a desk-based study to determine if the sites are at risk of additional contamination as a result of the operations undertaken throughout the duration of the WMRC. A second intrusive phase, which will be tendered separately, will be undertaken where necessary and based on the findings of the desk study for each of the sites. This will entail the investigation, collection and analytical testing of samples as deemed necessary during the Preliminary Contamination Risk Assessment. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/2b9281ef-a6ed-48a0-b5e4-4a775548ff56 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure (below threshold) | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 14 Nov 2025 | | Submission deadline | 16 Feb 2026 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 29 Mar 2026 - 18 Sep 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | MERSEYSIDE WASTE DISPOSAL AUTHORITY | | Locality | LIVERPOOL | | Post town | Liverpool | | Postcode | L3 1BP | | Country | England | | ITL 1 | TLD North West (England) | | ITL 2 | TLD7 Merseyside | | ITL 3 | TLD72 Liverpool | | Local authority | Liverpool | | Electoral ward | Waterfront South | | Westminster constituency | Liverpool Riverside | | Delivery location | TLD North West (England) | ## CPV Codes ### Divisions - 45 - Construction work - 71 - Architectural, construction, engineering and inspection services - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 45111250 - Ground investigation work - 71351500 - Ground investigation services - 71510000 - Site-investigation services - 90715000 - Pollution investigation services - 90715100 - Chemicals and oil pollution investigation services ## Release History - 14 Nov 2025 at 17:45 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/2b9281ef-a6ed-48a0-b5e4-4a775548ff56 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/2b9281ef-a6ed-48a0-b5e4-4a775548ff56 14th November 2025 - Opportunity notice on Contracts Finder - https://www.mytenders.co.uk/search/show/search_view.aspx?ID=NOV170564 NOTE: To register your interest in this notice and obtain any additional information please visit the myTenders Web Site at the link provided. ## Notice URLs - http://https://www.merseysidewda.gov.uk/ ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
