Competitive flexible procedure description

A single tender is being issued for both GA fleets. Each fleet will be presented as a 'Lot'. A single supplier will be allowed to bid for one or both 'Lots' and provide the cost benefits associated with economies of scale:

• Lot 1 = 'North Fleet' (Class 745 and Class 755);

• Lot 2 = 'South Fleet' (Class 720).

A response against the entire maintenance scope for each Lot will be required by the tender, with each bidder determining whether each item of scope will be delivered internally or via subcontract. For non-OEM bidders, it is a requirement that they will negotiate a TSSSA-style agreement with the associated OEM in order to submit a complete response.

The stages are intended to be:

• Conditions of participation;

• Tender stage (consisting of clarification and evaluation and negotiation substages);

• Award stage;

• Mobilisation stage.

The conditions of participation and pass criteria are detailed within the Procurement Specific Questionnaire available via the Delta eSourcing platform. The technical conditions of participation are:

• You must demonstrate suitable relevant experience for this procurement and provide contract examples.

• You must demonstrate suitable relevant experience of sub-contractor management, including management or delivery of a TSSSA.

• You must be willing to enter into a Train Services Agreement (TSA) with GA and can and will negotiate the terms of a Technical Support and Spares Supply Agreement (TSSSA) with the OEM relating to the appropriate Lot.

• You must be RISQS accredited to the RICCL codes E.E.2: Electrical Multiple Units / Maintain (MAN) and E.E.3: Diesel-Electric Multiple Units / Maintain (MAN)

Justification for not publishing a preliminary market engagement notice

Greater Anglia (Transport UK East Anglia Limited) undertook a preliminary market engagement exercise with maintenance service providers in April 2025. The purpose of the exercise was to establish the appetite and capability of the rolling stock maintenance market to participate in a tender for maintenance of the GA fleets when the current maintenance agreements expire.

A Preliminary Market Engagement Notice was not issued as Greater Anglia (Transport UK East Anglia Limited) as a private utility was not required to, and timescales and arrangements for transfer to GA Trains Limited were not defined.

Further details are provided in the PSQ document.
