Bazalgette Tunnel Ltd (trading as Tideway) has gone out to tender with a contract for maintenance services for the Thames Tideway Tunnel worth an estimated £11.5 million.
Following completion of the works on the Thames Tideway Tunnel project, the licensed provider set up to finance, build, maintain and operate the Tunnel will be responsible for maintaining the majority of project assets during the project's System Acceptance Period which is currently targeted to run from summer 2025.
Tideway is seeking a provider to deliver planned, preventative and reactive maintenance services across the specified surface and near-surface assets at 21 sites in accordance with Tideway’s maintenance plans for the System Acceptance Period and possibly beyond subject to novation.
The assets to be maintained under the Contract are generally categorised as:
- Near-surface civils elements
- MEICA elements
- Building services elements
- Infrastructure elements
- Safety restraints
- Maintenance access hardware
Deep civils (e.g. main tunnel, connection tunnels, and shafts) are out of scope of the contract.
Following the completion of System Acceptance the assets (with the exception of deep civils) are transferred to Thames Water who take on maintenance responsibilities - the contract will include provisions for extensions and novation beyond the initial term up to a maximum 10 year term. The estimated total value of £11.5 million has been based on the initial term of 27 months - the value is indicative and depends on business needs over the term. The initial term will have options to extend to a total possible aggregate term of 10 years should all possible extension and novation options be exercised.
The services under the contract to be delivered in London in relation to the Thames Tideway Tunnel Project will generally be required across the 21 identified sites.
