The contract duration will be up to twenty years, with an estimated value of £10 billion each. The tender period ends on 17th July 2024, and the contract period is from 1st April 2026 to 31st March 2029. This tender presents significant business growth opportunities for companies in the engineering and construction sectors. Suitable businesses would need to engage in competitive dialogue as the procurement method. Small and medium-sized enterprises (SMEs) are particularly welcome to participate, aligning with the UKIFS's aim to develop extensive industrial capabilities for a world-leading fusion delivery industry. ## Notice UKAEA (on behalf of UKIFS - a special purpose vehicle to be established during the procurement process as the delivery body for STEP) is conducting this Procurement for an Engineering Partner (EP) and a Construction Partner (CP), who, together with a Fusion Partner (determined to be UKAEA), will bring together and develop extensive industrial capabilities to design and build a UK prototype fusion energy plant capable of delivering net-energy to the grid, and build a world-leading fusion delivery industry. The Procurement is divided into two lots: * Lot 1: Engineering Partner (EP) * Lot 2: Construction Partner (CP) Both contract terms will be an initial three (3) year period, followed by three (3) optional extension periods of four (4), six (6) and seven (7) years (these durations are subject to change as the Programme develops). UKIFS will have the right to exercise an extension option on six (6) months' notice. The maximum contract duration for both contracts will be twenty (20) years with an estimated value of PS10,000,000,000 each across this period. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/00718f9a-4b70-4e18-a83c-6cd06d04ca05 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Selective | | Procurement method details | Competitive dialog | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 22 May 2024 | | Submission deadline | 17 Jul 2024 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 31 Mar 2026 - 31 Mar 2029 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £1 | | 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 | UNITED KINGDOM ATOMIC ENERGY AUTHORITY | | Locality | ABINGDON | | Post town | Oxford | | Postcode | OX14 3DB | | Country | England | | ITL 1 | TLJ South East (England) | | ITL 2 | TLJ1 Berkshire, Buckinghamshire and Oxfordshire | | ITL 3 | TLJ14 Oxfordshire CC | | Local authority | South Oxfordshire | | Electoral ward | Sandford & the Wittenhams | | Westminster constituency | Didcot and Wantage | | Delivery location | Not specified | ## CPV Codes ### Divisions - 45 - Construction work - 66 - Financial and insurance services - 71 - Architectural, construction, engineering and inspection services ### Codes - 45200000 - Works for complete or part construction and civil engineering work - 45220000 - Engineering works and construction works - 66519000 - Engineering, auxiliary, average, loss, actuarial and salvage insurance services - 71000000 - Architectural, construction, engineering and inspection services - 71240000 - Architectural, engineering and planning services - 71250000 - Architectural, engineering and surveying services - 71300000 - Engineering services - 71310000 - Consultative engineering and construction services - 71311000 - Civil engineering consultancy services - 71312000 - Structural engineering consultancy services - 71313000 - Environmental engineering consultancy services - 71318000 - Advisory and consultative engineering services - 71320000 - Engineering design services - 71321000 - Engineering design services for mechanical and electrical installations for buildings - 71322000 - Engineering design services for the construction of civil engineering works - 71323000 - Engineering-design services for industrial process and production - 71323200 - Plant engineering design services - 71330000 - Miscellaneous engineering services - 71333000 - Mechanical engineering services - 71334000 - Mechanical and electrical engineering services - 71336000 - Engineering support services - 71337000 - Corrosion engineering services - 71340000 - Integrated engineering services - 71350000 - Engineering-related scientific and technical services - 71540000 - Construction management services ## Release History - 22 May 2024 at 14:38 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/00718f9a-4b70-4e18-a83c-6cd06d04ca05 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/00718f9a-4b70-4e18-a83c-6cd06d04ca05 22nd May 2024 - Opportunity notice on Contracts Finder - https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=81210&B=UKAEA Additional data - https://uk.eu-supply.com/ctm/Company/CompanyInformation/Index/72814 User / Company ## Notice URLs - http://www.gov.uk/government/organisations/uk-atomic-energy-authority ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
