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 £300m . 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.
