This research project aims to test high-pressure washing procedures on UK concrete surfaces contaminated with specific radionuclides. The procurement is classified under research and development services, with a tender period ending on 23rd September 2022. The project location is in London, United Kingdom, and the contract period is from 10th October 2022 to 31st March 2023. This tender opportunity is suitable for businesses in the services industry, particularly those experienced in research and development services. Small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprise (VCSE) organisations are encouraged to participate. Given the focus on decontamination of concrete surfaces post-radiological incidents, businesses with expertise in radiological decontamination and waste management could find this tender well-suited for their capabilities. The project offers potential for business growth through collaboration with Defra in developing effective decontamination procedures for urban surfaces in the UK. ## Notice The Department for Environment, Food and Rural Affairs (Defra) is commissioning small-scale research to investigate the viability of high-pressure washing for decontaminating UK concrete building materials following a major radiation incident. Defra is the designated Lead Government Department in England for coordinating the recovery from Chemical, Biological, Radiological and Nuclear (CBRN) incidents in England. To that end, Defra facilitates UK access to decontamination capabilities for buildings, environment, and infrastructure following a CBRN incident. When not recovering from a CBRN event, Defra develops recovery policy and operational capability by working closely with cross government colleagues, academia, and industry. The aim of this project is to test the suitability of high-pressure washing procedures to decontaminate UK concrete surfaces contaminated with 85Sr, 137Cs, and 152Eu. This project consists of 2 stages. The objectives of stage 1 of this project are: - Source suitable concrete samples from the UK built environment and then contaminate with 85Sr, 137Cs, and 152Eu under laboratory conditions (Objective 1). - Measure radionuclide depth profiles after aging the contaminated samples for a maximum of 2 months. This aging period is considered representative of decontamination operations after a significant radiation incident (Objective 2). The objectives of stage 2 of this project are: - Determine the effect of three different water pressures (between 2,000 and 7,000 psi) on the radionuclide removal rates from contaminated concrete samples (Objective 3). - Examine the potential for high pressure washing to induce aesthetic and/or physical damage to the decontaminated materials by visual inspection and appropriate microscopy technique(s) (Objective 4). It is important to note that the duration of stage 1 of the project is 5.5 months. A 6-month extension to the project is available for stage 2, subject to satisfactory completion of stage 1. It is acceptable for Tenderers to submit a tender for stage 1 of the project only. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/0d27ccbb-2d4b-42b8-b7b2-1e56b0a50d2f | | 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 | 30 Aug 2022 | | Submission deadline | 23 Sep 2022 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 9 Oct 2022 - 31 Mar 2023 | | 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 | DEFRA NETWORK ETENDERING PORTAL | | 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 | TLI London | ## CPV Codes ### Divisions - 73 - Research and development services and related consultancy services ### Codes - 73000000 - Research and development services and related consultancy services ## Release History - 30 Aug 2022 at 11:28 - TenderAmendment - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/0d27ccbb-2d4b-42b8-b7b2-1e56b0a50d2f - 17 Aug 2022 at 09:47 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/0d27ccbb-2d4b-42b8-b7b2-1e56b0a50d2f ## Documents - https://www.contractsfinder.service.gov.uk/Notice/0d27ccbb-2d4b-42b8-b7b2-1e56b0a50d2f 30th August 2022 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/e8afd6fe-2118-4923-b68f-4a1dbb68e291 n/a - https://defra.bravosolution.co.uk Link to eSourcing Portal - https://www.contractsfinder.service.gov.uk/Notice/Attachment/3939c035-d4f4-4476-bebf-37267e3d8491 n/a ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
