Bazalgette Tunnel Ltd – which trades as Tideway – has launched a market engagement exercise for the outsourcing of its information systems to consolidate various services to a single holistic managed service provider.

Tideway as a company currently comprises circa 250 end users and includes functions and related systems, applications, and general operating model appropriate to support a large infrastructure project.
Following completion of works on the Thames Tideway Tunnel (TTT) project, Tideway will be transitioning from a construction project into a long term “steady state” utility company responsible for the long term ownership, financing and maintenance of the TTT so that it is available for use in conjunction with Thames Water's sewer network.
At steady state end user numbers will reduce to 30-40 with core functions covering Finance (treasury), Regulation, limited physical (tunnel) maintenance and corporate services.
Tideway is now exploring service delivery options for outsourcing Information Systems to consolidate various services to a single holistic managed service provider, with services commencing around June 2025. The target of achieving steady state service, application and user landscape is around December 2026.
The service provider will also assist Tideway in ongoing consolidation of providers and services, managing the reduction of end users during the transition period, and close-out of construction-phase applications and associated data archiving. Key service requirements will include, but not limited to :
- Service Operations
- Service Management
- Networks
- Security
- Information Management
- Project Management (professional services)
The company has issued a Periodic Indicative Notice inviting interested suppliers to respond initially to a market engagement questionnaire so that Tideway can better understand the industry, its capabilities, capacity and appetite for a potential service package.
Suppliers who want to express interest in this opportunity and to receive the market engagement documentation should register through emailing procurement@tideway.london with relevant organisation and individual contact details.
Suppliers who register will then be provided with a market engagement briefing paper which will provide further details of the package in question and a market engagement questionnaire for review and completion for issue back to Tideway.
Tideway said the information provided will assist with its internal procurement planning prior to the issue of a Pre-Qualification Questionnaire which is currently planned for later this year.
Estimated date of publication of a formal contract notice is currently 16 September 2024.
