What is being bought
Published requirement descriptionDescription
The proposed framework agreement is intended to secure LUL 73TS Piccadilly Line, 92TS Central Line and 96TS Jubilee Line fleets' supply of components for maintenance and repair of various pneumatic train borne systems. The proposal is to identify potential suppliers by issue of a Preliminary Market Engagement document containing a Market Survey Questionnaire (MSQ) and appendix that lists the components with part numbers and descriptions.
Scope
The scope includes the supply of specific components needed to ensure adherence to TfL for repair and overhaul of on train components of the 73TS, 92TS and 96TS fleets.

The appendix includes the following types of components:
- Hoses and nylon tubing - used to connect various functioning parts
- Filters - for removal of moisture, particles and debris that may cause equipment malfunction
- Valves and regulators - to release, stop or control air pressure
- Various seals/O rings - to ensure integrity of pneumatic connections
- Pipework fittings - for connections between pneumatic pipes and between pipework and pneumatic components
Objective
- Identify suppliers with capability to supply the components as specified in the appendix
- Assess capacity to deliver to depot volume and delivery requirements
- Evaluate supplier assurance capability and adherence TfL requirements
- Evaluate supplier ability to maintain supplies for 5+ years

How Transport for London buys Railway and tramway locomotives and rolling stock and associated parts (CPV 3460), and who usually turns up
Transport for London’s published record next to the market for the same work. Frameworks and DPS are left out: they draw different bid counts. Whole-market view: Railway and tramway locomotives and rolling stock and associated parts (CPV 3460) →
How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
i
How often small and medium firms win.
Share of awards where the winner’s size is known.
The counts under this question show how many awards have a known supplier size.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
i
How often local firms win similar work.
Winners with a registered address in the delivery region, out of awards with a known address.
Local means the winner is registered in the region where that award was delivered. The market figure counts awards delivered in Greater London (authority’s region).
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners were registered outside the region where that award was delivered.
i
How long buyers here take to decide after bids close.
Middle value in days from the bid deadline to the award date, on competitions that published both.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards have an award date within 152 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
Both shares are minimums: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?
i
How many bids past lots received.
Each colour is a bid-count range. Only competed lots with a published count are included.

How did awards compare with estimates?

Where winning prices landed against estimates.

Past prices are a guide, not a bid price.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
