Notice Title

Owner's Engineer

Notice Description

The OE will provide essential independent assurance to the Intelligent Customer and Intelligent Client for the Small Modular Reactor project. This will support the deployment of first-of-a-kind nuclear technology in the UK and facilitate GBE-N's goal of reaching a Final Investment Decision. In particular, the OE will act as a 'client friend' to the Intelligent Customer and Intelligent Client and provide competent resource to undertake specification, oversight, audit, review and advice for decisions relating to design, scope, budget, risk, delivery and contract compliance. It will also play the role of subject matter expert to deliver independent technical and delivery Line of Defence 2 assurance on major design and build contracts. The maximum total contract value is PS300m . However, it is not possible to predict an exact outturn value at this stage due to the length of the contract and inherent uncertainties in scope, which drive variability in the volume of work instructed. In addition, progression through design stages and associated milestones or gates will determine the timing and extent of services required, potentially influencing the overall contract value over time. As envisaged in the tender notice, the duration of the OE contract will depend on matters agreed with the SMR Technology Partner. The current assumption remains that the OE contract will have a 14-year term, but a completion date will be set during the term of the contract in accordance with its terms and to reflect the term of the SMR Technology Partner contract. In accordance with section 51 of the Procurement Act 2023, GBE-N will observe a standstill period. Whilst the mandatory standstill period concludes on the 18th February, to ensure 8 full Working Days the standstill period will conclude at 14:30 19th February.

Planning Information

GBN has already conducted an early market engagement exercise with suppliers to test GBN's proposed approach against market experience from other large infrastructure projects and use industry knowledge to assist GBN in refining its proposed approach. GBN engaged with suppliers by providing an information pack which outlined GBN's proposed delivery model and gave further context on the role of the OE within this model. The pack stated that from the commencement of the contract, any prospective OE would need to commit to providing the technical and programme capabilities stated in the requirements. Within the information pack provided to suppliers, GBN included a questionnaire for suppliers to complete in order to help GBN refine its proposed approach to the delivery of the OE requirement. Suppliers returned their completed questionnaires electronically to GBN.  The questionnaire covered the role of the OE, GBN's contracting strategy, the number of OEs, alliancing, pricing, incentivisation, contract management, costing, liability and the potential to create joint ventures, consortia and special purpose vehicles, market capacity and conflicts of interest.

        "description": "The OE will provide essential independent assurance to the Intelligent Customer and Intelligent Client for the Small Modular Reactor project. This will support the deployment of first-of-a-kind nuclear technology in the UK and facilitate GBE-N's goal of reaching a Final Investment Decision. In particular, the OE will act as a 'client friend' to the Intelligent Customer and Intelligent Client and provide competent resource to undertake specification, oversight, audit, review and advice for decisions relating to design, scope, budget, risk, delivery and contract compliance. It will also play the role of subject matter expert to deliver independent technical and delivery Line of Defence 2 assurance on major design and build contracts. The maximum total contract value is PS300m . However, it is not possible to predict an exact outturn value at this stage due to the length of the contract and inherent uncertainties in scope, which drive variability in the volume of work instructed. In addition, progression through design stages and associated milestones or gates will determine the timing and extent of services required, potentially influencing the overall contract value over time. As envisaged in the tender notice, the duration of the OE contract will depend on matters agreed with the SMR Technology Partner. The current assumption remains that the OE contract will have a 14-year term, but a completion date will be set during the term of the contract in accordance with its terms and to reflect the term of the SMR Technology Partner contract. In accordance with section 51 of the Procurement Act 2023, GBE-N will observe a standstill period. Whilst the mandatory standstill period concludes on the 18th February, to ensure 8 full Working Days the standstill period will conclude at 14:30 19th February.",

There will be two stages in the OE procurement. In the first stage, tenderers will need to respond to the Procurement Specific Questionnaire (PSQ), which will include conditions of participation. The PSQ will cover topics including, but not limited to, conflicts of interest, economic and financial standing and the tenderer's ability to provide the technical and programme capabilities listed later in this notice. The capabilities set out in the technical ability conditions of participation section below can be delivered in various ways, including (but not limited to) by a tenderer and its supply chain, a joint venture, a special purpose vehicle or a consortium. Please note that while GBN considers this list of capabilities to be comprehensive, it reserves the right to change them (and any other information provided in this notice) by the time of launching the OE procurement. If the response submitted by a tenderer as part of the first stage of the procurement satisfies all the relevant conditions, the tenderer will be invited to submit a tender as part of the second stage of the procurement. GBN will then assess the tenderer's proposals against questions covering Technical, Commercial and Social Value criteria. Please note that GBN reserves the right to refine its award criteria during the procurement process. All documentation can be found on Jaggaer. All communications regarding the procurement will be held via Jaggaer. All responses will be submitted via Jaggaer. https://beisgroup.ukp.app.jaggaer.com/"
