The procurement is in the services category and the tender deadline is on 24th October 2023. The contract period is from 20th November 2023 to 31st March 2024. This tender is an open procedure below threshold and is suitable for small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprise (VCSE) organisations. This procurement opportunity by the Environment Agency aims to provide groundwater modeling services for the Lichfield Permo-Triassic Sandstone aquifer. Businesses in the research and development consultancy sector, particularly those with expertise in groundwater modeling, simulation, and Modflow 6 software, are well-suited to compete for this tender. The extended simulation period, model refinements, and predictive scenarios offer growth prospects for businesses looking to contribute to environmental protection and water resource management. ## Notice The procurement documents are available for unrestricted and full direct access, free of charge, at https://defra-family.force.com/s/Welcome Any questions, requests to participate or tender submissions must be submitted electronically via this portal. The Lichfield Permo-Triassic Sandstone aquifer is a regionally significant groundwater resource providing public water supply to areas of south and central Staffordshire. The aquifer is also an important source of baseflow to several tributaries of the River Trent. The Lichfield groundwater model was developed for the Environment Agency during the period 2005-2008. The main purpose of this model was to increase the ability of the Agency to make abstraction licensing decisions on a sound scientific basis and, in doing so, protect and/or enhance sensitive surface water features on the outcrop of the Lichfield Permo-Triassic Sandstone aquifer. In 2012 the simulation period was extended up to March 2011. Subsequently, the model was recalibrated and the ability to simulate distributed runoff and total stream flows were added with the help of 4R code in 2013. The main tasks of the current project will be to further extent simulation period up to the end of March 2023, complete various model refinements and improve model calibration and credibility. Moreover, the model will be migrated to Modflow 6. Finally, a set of standard and predictive scenarios will be completed using the refined and updated historical baseline. The updated model will be also used to delineate Source Protection Zones (SPZs) for a number of public water supply sources. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/17b8a541-3256-44dd-bb6b-d9ce7d07962e | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure (below threshold) | | Tender suitability | SME, VCSE | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 28 Sep 2023 | | Submission deadline | 24 Oct 2023 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 20 Nov 2023 - 31 Mar 2024 | | 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 | ENVIRONMENT AGENCY | | Locality | LONDON | | Post town | South West London | | Postcode | SW1P 3JR | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 73 - Research and development services and related consultancy services ### Codes - 73200000 - Research and development consultancy services ## Release History - 28 Sep 2023 at 13:50 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/17b8a541-3256-44dd-bb6b-d9ce7d07962e ## Documents - https://www.contractsfinder.service.gov.uk/Notice/17b8a541-3256-44dd-bb6b-d9ce7d07962e 28th September 2023 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/c9f27276-de9a-48ba-a7d7-d573383d3a63 C20943_DgC_Bidder_Pack_Proc_Spec_Below_Threshold_final ## Notice URLs - https://defra-family.force.com/s/Welcome ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
