What is being bought

Published requirement description

Transport for London (TfL), on behalf of its subsidiary London Underground Limited (LUL), is undertaking early market engagement to support the development of a comprehensive and flexible Rail Vehicle Electronics Framework Agreement.

TfL will subsequently issue a Market Sounding Questionnaire (MSQ) document which details the scope of work required.

TfL seeks to engage with the supply market to understand capability, capacity, and viable delivery approaches for the Rail Vehicle Electronics Framework Agreement. The scope includes all electronics assemblies on rail vehicles that operate on the TfL Network, including but not limited to the following:

  • Printed circuits and boards (ICS code 31.180)
  • Electronic component assemblies (ICS code 31.190)
  • Integrated circuits and microelectronics (ICS code 31.200)
  • Software (ICS code 35.080)

Note "ICS" means the International Classification for Standards.

The framework will enable TfL to engage pre-approved suppliers for a range of Goods and Services including but not limited to:

Goods:

  • Development and provision of prototype electronic assemblies to replace obsolete systems, ensuring compatibility with existing infrastructure. All replacement components must undergo functional validation and certification of compliance to relevant Railway standards, including but not limited to:
  • EMC (Electromagnetic Compatibility)

o Electronics environmental standards

  • Shock & vibration testing (where significant design changes occur)
  • IPC quality standards - supplier must demonstrate training and adherence to IPC standards in their working procedures
  • Supply of display units and Human Machine Interface (HMI) components.

Services:

  • Surveying
  • Investigation
  • Design and provision of rail vehicles modifications required to support the integration and operation of replacement electronic assemblies, undertaken in close collaboration with TfL engineering teams to ensure compatibility and avoid duplication of work.
  • Reverse engineering of legacy rail vehicles electronic systems.
  • Obsolescence reporting and lifecycle analysis.
  • Condition Assessment
  • Repairs and refurbishments of electronic assemblies.
  • Overhauling & Testing including collaborative overhaul package undertaken in partnership with London Underground's Railway Engineering Works (REW) Electronics Workshop. Such package may include:
  • Reverse engineering of components to be overhauled.
  • Production of schematics to support overhaul activities
  • Identification of components requiring replacement and obsolescence solutions
  • Development of mechanisms to overcome onboard software barriers
  • Design and build of suitable test rigs to confirm correct functional operation after overhaul.
  • Creation of overhaul documentation to enable in-house capability building
  • Non-routine sourcing of obsolete components, including grey market sourcing with ap-propriate assurance mechanisms such as counterfeit inspection, independent bench testing and validation.
  • Approaches to component substitution, functional equivalency analysis, and obsolescence avoidance strategies, including grey market sourcing with appropriate assurance mechanisms such as counterfeit inspection, independent bench testing and validation of components.
  • Documentation preparation
  • Document review
  • Verification and validation, including type testing of the rail vehicle modification in accordance with the conformity assessment plan.
  • Technical support
  • Any other engineering services
  • Document management of the Contractual Documentation until delivery to the Company.
  • Preservation, including storage and transport, of the Goods, Contractual Documentation and supporting items until delivery to the company.
  • Services required by the Quality and Safety Plan

How the contest usually goes

Question for the bid
This buyerTransport for London · division 50
What to do with it
How often do SMEs win?
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.

Last 36 months.

Buyer: 3 of 11 known-size awards · market: CPV 5010 · UK-wide, n=39
27%67%

Small firms have won here. Neither number says whether you qualify; it describes who has been winning.

How often do local suppliers win?
i

How often local firms win similar work.

Winners with a registered address in the delivery region, out of awards with a known address.

Here, local means registered in Greater London.

A local branch does not count if the registered address is elsewhere.

Last 36 months.

Buyer: 5 of 20 known-location awards · market: CPV 5010 · Greater London, n=5
25%60%

Most of this buyer’s recorded winners are registered outside Greater London.

How long to a decision?
i

How long buyers here take to decide after bids close.

Middle value in days from the deadline to the first award notice, on competitions that published both dates.

Only decided tenders count, so slow ones still waiting are not in.

Last 36 months.

Buyer: 5 decided notices · market: CPV 5010 · UK-wide, n=15
73 days54 days

Half of these awards were announced within 73 days of the bid deadline.

How often single-bid or direct?
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.

Last 36 months.

Buyer: at least 17 of 22 procurements with awards had no recorded rival · market: CPV 5010 · UK-wide, n=62
77%60%

How many bids this lot may attract.

The forecast uses similar past competitions. The bar shows either that forecast or past bid counts; the line below says which.

Each lot shows its own forecast based on its own category; forecasts for different lots of the same notice are not comparative. The bar shows 159 past lots.

Where the award price may land.

The forecast uses similar awards and the buyer’s estimate. The band covers the middle half of likely prices.

No comparable awards for this lot yet.

A statistical guide from past awards, not a price to bid.

—Estimate not published
The buyer published no estimate for this lot, so there is nothing to forecast against. A price prediction here would be a number about a number we do not have.

i

Who has done similar work for this buyer.

Past contracts are matched by buyer, title and type of work.

A past supplier may not bid again.

No earlier contract of this buyer matches this lot on the published record.

Who could compete for this lot?

Firms with relevant past wins. On a framework, we show firms on that agreement.

None is confirmed as a bidder.

Candidate suppliers for this notice have not been worked out yet, so this is not a verdict that nobody fits.

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.
