Description
This Contract Notice relates to F01: Prior information notice (prior information only) Notice reference: 2024/S 000-003733 Published 5 February 2024, 3:46pm. Network Rail currently has a national Framework Agreement for the provision of Track Bed Investigations which will be re-tendered to satisfy business needs. The framework scope will include standard and deep track bed investigations, concrete coring and various drainage surveys, which are used for the design and specification of the trackbed for track renewals. The framework will be specific to the Engineering Services Design Delivery function in Network Rail. The workbank comes from client teams in the Network Rail regions who will call-off from the framework when track bed investigations are required. Due to the work-related nature of these activities, the framework terms & conditions will be based on the NR29 Framework Contract for Network Rail Amended NEC4 Engineering and Construction Short Contract. The framework will run for an initial period of five years, and Network Rail will have the option to extend for two further one-year periods, providing the flexibility for a five, six or seven year framework duration. The tender will be split into two lots as follows; lot 1 will be for track bed investigations in England & Wales, and lot 2 will be for those in Scotland. Based on historic usage we estimate that lot 1 will account for approximately 90% of demand and lot 2 the remaining 10%. No more than one supplier will be awarded a framework for each lot, however one supplier could win both lots, or two suppliers could win a lot each. Network Rail will undertake a pre-qualification stage which will down select to a shortlist of Candidates that shall be invited to tender.
