PQQ for Air Reservoir overhaul
Buyer: ScotRail Trains Limited →
What is being bought
ScotRail Trains Limited (hereinafter referenced as ScotRail) are looking to tender for the provision of an Air Reservoir (various) overhaul service in accordance with rail safety critical and rail standards, and using Scotrail-provided materials. Noting the Out of Service (OSD) for HSTs, the business has revised the procurement strategy and the tender will now be separated into Lots to account for the differing contract end date required for the HSTs. - Lot 1 – for Class 153, 156 & 158 trains; and - Lot 2 – for HST Class 43 Power Car & Mark III Coach As part of the ITN process Suppliers will be able to bid for one or more Lots. An air reservoir is defined as a vessel (other than a pipe coil or ancillary fitting and part of the compressor) for containing compressed air. The group definition is based on the Reservoirs function, material and vehicle classification. ScotRail Trains Limited reserve the right to add or remove the numbers of overhauls per class of train, as the business requires.
Categories
Comparable-procurement analytics
Benchmarked against retained Find a Tender procedures with CPV division 50. The category anchor is Repair, maintenance and associated services related to railways and other equipment (50220000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.
| Comparison set | Procedures | Reported bids per procedure | Named award suppliers | Price evidence |
|---|---|---|---|---|
| Market: CPV division 50 | 6,102 | 4 median · 21 average (2,258 of 6,102 with a bid count) | 3.5 average (2,533 of 6,102 with named award suppliers) | Not published |
| Same buyer | 10 | 1 median · 1 average (1 of 10 with a bid count) | 1.3 average (3 of 10 with named award suppliers) | Not published |
| Similar published value (0.5×–2×) | 460 | 3 median · 4.8 average (11 of 460 with a bid count) | 1.4 average (11 of 460 with named award suppliers) | Not published |
“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.
Price-outcome signal
Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
