Classes 165 and 168 Tripcock Valve Overhaul Services
Authority: CHILTERN RAIL LIMITED (Public body)
What is being bought
Published requirement descriptionThis procuurement is for the provisdion of overhaul services for Classes 165 and 168 Trip cock valves. The trip cock valves are to be overhualed to a Chiltern Railways specification to improve the reliability of the valves and in turn the fleets to which they are installed.
The specification consists of a core scope with a list of mandatory change components and also componenets that are changed on condition following inspection.
The trip cock valves have not been overhauld recently so some valves could be excessively worn. Where this is the case, additional services could be required over and above the core specification to return the valves to a serviceable condition.
Whilst the overhaul services are ad-hoc in nature, it is expected that output volume will be circa 40 valves per annum.
- The authority expects to re-tender this requirement around 27 Oct 2030, 23:59 GMT.
- How the procedure runs: The process consists of Three stage procedure. Stage 1 - Invitation to Participate (ITP), which includes a procurement specific questionnaire which all bidders are required to complete. Bidders who were successfully shortlisted in Stage 1 were invited to participate in Stage 2. Stage 2 - Invitation to Submit Final Tenders (ISFT). Stage 3 - Preferred Bidder Stage. The highest scoring Bidder in stage 2 will be invited to engage in further discussions as part of a Preferred Bidder stage. This stage will be used to finalise the draft contract terms and conditions,
