This project, titled "Downs to the Sea and Improving Pulborough and Amberley Projects," falls under the classification of environmental rehabilitation works, reflecting its focus on enhancing water management and resilience against climate change. The tender process is currently at the amendment stage, with the deadline for submissions set for 20th April 2026, while the contract period will commence on 1st July 2026 and conclude on 31st October 2026. Located within the South Downs National Park, this project presents a compelling opportunity for firms specialising in environmental works and improvements in hydrological compartments. Businesses well-suited to pursue this tender will include small and medium-sized enterprises (SMEs) with expertise in environmental improvement and construction, particularly those experienced in tasks such as culverting, bunding, and managing wetland features. With an estimated contract value of £80,000, this limited procurement method via competitive quotation opens avenues for growth by allowing eligible companies to showcase their skills in enhancing ecological resilience and water management strategies. Prospective bidders are encouraged to engage with the detailed tender documents provided, including design specifications and pricing schedules, to adequately prepare their submissions. ## Notice RSPB Pulborough Brooks is a large nature reserve found in West Sussex. It sits within the South Downs National Park and is part of the Arun Valley. Recent works on the reserve have meant we have good control of water levels, but there are still improvements to be made. New rills/foot drains will provide better feeding opportunities. Culverting round the willow bed will create a greater area to store water to help sustain the wetland into drier summer months. Bunding will ensure access around the site for management and grazing and will ensure hydrological compartments are clearly defined. This work will help make the site more resilient to the wetter winters and drier summers we are seeing as a result of climate change. Wet features and scrapes will help hold water during drier times and replacing broken culverts will create better water flow and control. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/780e0a42-2a22-4340-8789-c2537f731131 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Limited | | Procurement method details | Competitive quotation (below threshold) | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 19 Mar 2026 | | Submission deadline | 20 Apr 2026 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 30 Jun 2026 - 31 Oct 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £80,000 | | 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 | ROYAL SOCIETY FOR THE PROTECTION OF BIRDS | | Locality | SANDY | | Post town | Stevenage | | Postcode | SG19 2DL | | Country | England | | ITL 1 | TLH East (England) | | ITL 2 | TLH2 Bedfordshire and Hertfordshire | | ITL 3 | TLH25 Central Bedfordshire | | Local authority | Central Bedfordshire | | Electoral ward | Sandy | | Westminster constituency | North Bedfordshire | | Delivery location | Not specified | ## CPV Codes ### Divisions - 45 - Construction work - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 45262640 - Environmental improvement works - 90722000 - Environmental rehabilitation ## Release History - 19 Mar 2026 at 09:32 - TenderAmendment - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/780e0a42-2a22-4340-8789-c2537f731131 - 19 Mar 2026 at 09:05 - TenderAmendment - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/780e0a42-2a22-4340-8789-c2537f731131 - 17 Mar 2026 at 10:33 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/780e0a42-2a22-4340-8789-c2537f731131 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/780e0a42-2a22-4340-8789-c2537f731131 19th March 2026 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/d60d56ee-0654-415c-83b8-af31aa5c0a84 Invitation to Tender - https://www.contractsfinder.service.gov.uk/Notice/Attachment/c6eb82d4-8ccb-45f7-959e-4219f50f751d Pricing Schedule - https://www.contractsfinder.service.gov.uk/Notice/Attachment/f0de915d-d947-471f-8374-ca17b4a7fdf2 Groundworks schedule including specificaitons and clay quantities. - https://www.contractsfinder.service.gov.uk/Notice/Attachment/bd949b03-27d9-4a98-9dd6-82c69e423c1e Design Specifications including cross sectional diagrams. - https://www.contractsfinder.service.gov.uk/Notice/Attachment/3e5b9a7b-6c23-4f0b-91c3-9b0c564f895d Pre-construction information - https://www.contractsfinder.service.gov.uk/Notice/Attachment/26848681-382e-4f17-910f-87264a1937c2 Question Responses ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
