This tender for maintenance services presents an opportunity for businesses in the repair and maintenance industry to compete for a contract with Tideway. Interested parties must demonstrate their ability to provide planned, preventative, and reactive maintenance services for specified assets related to the Thames Tideway Tunnel project.

The contract includes options for extension up to a maximum term of 10 years, offering long-term growth potential for successful applicants.

## Notice

The Thames Tideway Tunnel is a major infrastructure project, urgently needed to protect the tidal River Thames from increasing pollution. London's sewerage system is no longer fit for purpose and spills tens of millions of tonnes of untreated sewage mixed with rainwater (combined sewage) into the tidal reaches of the River Thames every year. Bazalgette Tunnel Limited (BTL), is the licensed provider set up to finance, build, maintain and operate the Thames Tideway Tunnel. From Licence Award BTL trades and is known to the public as 'Tideway'. Following completion of the works on the Thames Tideway Tunnel project Tideway 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 therefore 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 For the avoidance of doubt 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, therefore the Contract will include provisions for extensions and novation beyond the initial term up to a maximum 10 year term. Interested parties must register on Tideway's e-sourcing portal and will be able to download the Pre-Qualification Pack ('PQP') including the form of response to be completed and returned to submit a compliant response. The registration process is set out in section VI.3) of this Contract Notice. The PQP contains further detail regarding Tideway, the scope of services and further detail on the Contract and the timeline and phases of the procurement. Whilst it is intended that the procurement will be run in accordance with the timeline and process described in the PQP, this contract notice and the Procurement Documents, Tideway reserves the right to amend or cancel any or all of the procurement at any time and/or amend the timescales.
