Welding Framework Southern Region

Network Rail Infrastructure Limited · Central government

In brief

Network Rail Infrastructure Limited has announced plans to buy construction and building maintenance work. This is an early notice: there is nothing to bid on yet, but it tells you a tender may follow.

It is a framework worth up to £72,000,000 excluding VAT: the most the buyer expects to spend across all suppliers, not one contract.

The contract runs for 3 years, up to 5 years with extensions, starting 1 February 2028.

The buyer says it is suitable for small and medium-sized businesses.

Built from the notice's own fields. Always check the official notice before you bid.

Competition

Typical: a median of 4 bids per contract for this buyer (from 44 awards in the last 12 months).

Dynamic purchasing system

Suppliers join a list the buyer can call on. You can usually apply at any time while it is open, and work is awarded later through smaller competitions between members.

What the notice says

Welding services within Network Rail refer to the provision of specialist rail welding and associated works required to maintain the safety, integrity and performance of the railway infrastructure. These services support the repair, maintenance and joining of rail assets, helping to ensure the continued safe and reliable operation of the network. The framework’s scope will cover aluminothermic rail welding, thermic and arc welding, welding repair works, rail grinding, weld inspection, rail burning and associated works, providing additional specialist capability and capacity where Network Rail is unable to meet operational requirements through internal resources.

How to bid

  1. Read the full notice on Find a Tender, including any tender documents it links to.
  2. Register your organisation on the Central Digital Platform (through Find a Tender) if you have not already. Suppliers need to be registered to take part in procurements under the Procurement Act 2023.
  3. Follow the submission instructions in the notice; it does not name an e-tendering portal.
