## Summary

Network Rail Infrastructure Ltd is set to award a national framework agreement for the provision of tamper and regulator services, focusing on railway-track maintenance. This procurement process belongs to the services industry category and covers locations throughout the UK. The procurement method is selective, with a competitive procedure involving negotiation. The process began on 7 May 2024, with bids due by 7 June 2024 and an invitation date set for 17 June 2024. The contract period is from 1 April 2025 to 31 March 2033, and there is an option to extend the term by two one-year extensions, subject to Network Rail's approval. The framework agreement aims to support approximately 15,000 operational shifts per year for track renewal and maintenance projects managed by Supply Chain Services (SCS).

This tender provides significant opportunities for businesses specialising in railway engineering and maintenance. Companies with robust fleets of on-track machines and plans to keep their equipment up to date and reliable are well-suited for this procurement event. The agreement ensures consistent demand throughout its term, fostering long-term business growth for selected suppliers. Network Rail's interest in understanding fleet update strategies indicates a preference for innovation and reliability, making this tender particularly attractive to businesses capable of delivering high-performance and cost-effective solutions. Large suppliers like Balfour Beatty Rail Limited and Colas Rail Limited, which have previously been involved, demonstrate the competitive nature and scale of the opportunity.

## Notice

This Procurement Event covers the provision of a national framework agreement to deliver Tamper and Regulator services to support track renewal and maintenance projects

### Lot Information

Lot 1

The purpose of this Procurement Event is to award a framework agreement to provide Tamper and Regulator services over a eight-year term from 01 Apr 2025. The proposed service enables Network Rail Regions and the Routes to support track renewal and track maintenance projects (thereby supporting freight-users and passengers) via a central framework agreement, managed by Supply Chain Services (SCS). Under the proposed arrangements, approximately 15,000 operational shifts will be delivered per year, and it is anticipated that demand will remain at a similar level for the duration of the framework agreement. Under the proposed service model, Supply Chain Services receives an annual maintenance and renewals plan from its regional customers. The on-track-machines (OTMs) offered under the framework agreement are then allocated to support those annual renewals and maintenance plans, having due regard to the capability of the OTMs, and the competitiveness of the shift-rates offered. The following variations during the term of the framework agreement shall be permissible (but with no commitment at the time of framework award): - The ability to extend the term of the agreement by a maximum of two one-year extensions (subject to the granting of prior approval by Network Rail's governance panel); - The ability to adjust shift rates to cater for the introduction of replacement OTMs - i.e. those destined to replace OTMs decommissioned for reasons of age and/ or poor reliability during the term of the framework agreement. For avoidance of doubt, this permitted variation does not cover the purchase of the OTMs themselves. - The ability to adjust shift rates to support the roll-out of European Train Control System (ETCS) functionality to OTMs - i.e. to reflect changes to the operational/ maintenance regimes. For avoidance of doubt, this permitted variation does not cover the fit-out of supplier-owned OTMs with ETCS equipment.

Renewal: Around two years prior to the planned expiry of the framework agreements (paying due regard to the take-up of any option to extend), a new Procurement Event will be mobilised to renew the framework agreements
