This project classified under site-investigation services targets the assessment of potential contamination at MWDA's operational waste management facilities in the North West region of the United Kingdom. The tender followed an open procedure which closed on 16 February 2026, with the contract commencing on 22 April 2026 and continuing until 18 September 2026. The contract, valued at £28,745, has been awarded to Hexa for £6,965. The procurement presents robust opportunities for businesses with expertise in ground investigation and pollution services, particularly those specialising in land condition assessments. This project is well-suited for companies capable of conducting comprehensive site assessments and offering both desk-based studies and intrusive investigative work when needed. The open procurement method enhances competitiveness, benefiting small and medium enterprises (SMEs). Engaging in projects like this can bolster portfolios in the environmental services sector and foster long-term growth by aligning with established authorities such as the MWDA. ## 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/b55c58dd-68da-4bce-b1c4-0858d5fec6f1 | | Notice type | Award Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Award | ## Dates | Field | Value | | --- | --- | | Publication date | 22 Apr 2026 | | Submission deadline | 16 Feb 2026 | | Future notice date | Not specified | | Award date | 21 Apr 2026 | | Contract period | 21 Apr 2026 - 18 Sep 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £28,745 | | Lots value | Not specified | | Awards value | £6,965 | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Not specified | | Awards status | Active | | 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) | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | HEXA | ## 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 - 22 Apr 2026 at 16:45 - Award - Award Notice - https://www.contractsfinder.service.gov.uk/Notice/b55c58dd-68da-4bce-b1c4-0858d5fec6f1 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/b55c58dd-68da-4bce-b1c4-0858d5fec6f1 22nd April 2026 - Awarded contract notice on Contracts Finder - https://www.mytenders.co.uk/search/show/search_view.aspx?ID=APR171244 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.
