Track Bed Investigation Framework re-tender

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. If you would like to take part in this Procurement Event then please send an email referencing this Contract Notice to philip.hunt@networkrail.co.uk no later than 12:00 on Friday 26th July 2024. The Pre-Qualification Questionnaire, which will contain all of the Procurement Documents, is being finalised and will be issued as soon as possible in the week commencing 22/07/2024 to any candidate that requests participation prior to the deadline as above, and you can start working on this upon receipt. A summary of key timeline events is as follows: Deadline to respond to this Contract Notice - 12:00 26/07/2024 Deadline to respond to the Pre Qualification Questionnaire (PQQ) - 06/09/2024 Invitation to Tender (ITT) issue date - 28/11/2024 Deadline to respond to ITT - 23/01/2025 Contract Award Decision - 12/06/2025 Contract Commencement - 17/07/2025 Lot 1: Track Bed Investigation Framework re-tender - England & Wales The specification for the Track Bed Investigation Framework covers the following track bed investigation and associated works, and site & factual reporting which are to be provided for track sites in England & Wales: Standard Track Bed Investigation: • Determining the condition of the existing track bed and sub-grade • Assessing the condition of the existing lineside drainage. • Dynamic Cone Penetration (DCP) to determine the soil structural properties. • Trial trenches to determine drainage paths and lateral variation of track bed materials. • Categorising of Spent Ballast for disposal • Measuring structural constraints (clearances) to support the construction phase and compliance with COM Regulations 2015 (Design Risk Register) to determine construction risks and mitigations. Deep Track Bed Investigation • Deeper window sampling and Standard Penetration Test (SPT) using heavy probing techniques for investigating Track Bed Stabilisation sites. Additional Works and Other Investigation Techniques • Stiffness Measurement surveys using Falling Weight Deflectometer (FWD), and Light Weight Deflectometer (LWD). • Drainage level surveys/topographical surveys to support the design track of drainage systems. • Concrete coring of slab track or other associated foundations • Material testing • Rail and sleeper deflection monitoring using cameras, Geophones or similar. Lot 2: Track Bed Investigation Framework - Scotland's Railway The specification for the current Track Bed Investigation Framework covers the following track bed investigation and associated works, and site & factual reporting which are provided in Scotland: Standard Track Bed Investigation: • Determining the condition of the existing track bed and sub-grade • Assessing the condition of the existing lineside drainage. • Dynamic Cone Penetration (DCP) to determine the soil structural properties. • Trial trenches to determine drainage paths and lateral variation of track bed materials. • Categorising of Spent Ballast for disposal • Measuring structural constraints (clearances) to support the construction phase and compliance with COM Regulations 2015 (Design Risk Register) to determine construction risks and mitigations.
