Section six. Complementary information

six.3) Additional information

All financial values stated in this notice are calculated using current prices plus assumed inflation based on RPI forecast rates to 2034. All values are estimates only and the final outturn values will depend on the precise works and services required to be delivered, the means of delivery, the way in which programme and project risks materialise, the actual rates of inflation up to completion of the programme, and other factors.

The precise details of each identified project, including specific location, route, form of electricity network infrastructure, construction methodology, and any associated mitigation or enhancement schemes are indicative and remain to be confirmed. The final project details are subject to all necessary consents being obtained (such as any required DCO, Electricity Act 1989 consent or planning permission), the requirements of those consents, and the terms of any necessary land rights to be secured to enable project delivery. SPT gives no commitment as to the basis on which any necessary consents or land rights will be applied for, or obtained.

This Framework Agreement, along with other framework agreements that SPT may procure through separate procurement processes, will contribute to SPT's delivery of its strategic projects under the Holistic Network Design (HND) model (which are funded by the Accelerated Strategic Transmission Investment, Large Onshore Transmission Investment and Medium Sized Investment Project frameworks) as well as any baseline projects forming part of SPT's RIIO-T2 and RIIO-T/3 price control settlements and any customer connection projects that SPT considers appropriate to be delivered under this model. For the avoidance of doubt, SPT may have separate arrangements for the delivery of similar works to the works which SPT intends to procure under the Framework Agreement but such arrangements may be based on a different delivery model.

It is currently anticipated that SPT's HND programme will be delivered by the partners through these Framework Agreements and the call-off contracts awarded under them, and the full scope of that is included in the scope advertised by this notice.

However, and without limiting that, the works and services awarded to the partners through this Framework Agreement, and the other framework agreements, may extend beyond work required for the HND programme to involve additional works and services, through the award of further contracts in reliance on the procedure in Regulation 48(4)(e) of the Utilities Contracts (Scotland) Regulations 2016 concerning direct awards for new works, services or both, consisting of the repetition of similar works or services. Any contracts for new works or services consisting of the repetition of similar works or services will (as relevant in the circumstances) conform to the requirements of SPT's HND programme and / or for a particular project for which contracts are called-off under these Framework Agreements

six.4.3) Review procedure

Precise information on deadline(s) for review procedures

Any proceedings relating to a breach of a duty owed by SPT to an economic operator under the Utilities Contracts (Scotland) Regulations 2016 in relation to this procurement must be started within 30 days beginning with the date when the economic operator first knew or ought to have known that grounds for starting the proceedings had arisen unless the court considers that there is a good reason for extending the period within which proceedings may be brought, in which case the court may extend that period up to a maximum of 3 months from that date.
