What is being bought
Published requirement descriptionContract details for notice for the Core Valley Lines (CVL) Transformation: Complex track works with associated level boarding works
- How the procedure runs: Request to Participate Stage - Deadline 15/10/25 - all bidders that meet minimum pass/fail requirements will be invited to tender. Qualified bidders will be invited to Tender Stage late October 2025 with deadline of mid/late December for return of Tenders
- No preliminary market engagement: Due to the complexity and scale of the works, the following capabilities are essential: Planning, ordering and management of Railway Engineering Trains and On-Track Machines Provision and site management of Strategic Plant Provision and site management of On-Track Plant, including POS compliance These requirements significantly narrow the pool of capable suppliers. The market for such works is typically concentrated within Network Rail’s regional track alliances, limiting broader competition

What this means for your bid
- Price carries 60 of 100 points: a 10% discount moves about 6 points. This one is won on the number: sharpen the price before polishing the prose.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
