Contractor wanted for Super Sewer testing phase

London’s new super sewer client Tideway is set to start the hunt for a contractor to maintain thousands of infrastructure assets through the project’s performance and reliability testing phase.

With the main tunnel and its connection tunnels fully excavated and more than 85% of the construction work complete, the Tideway team is preparing to enter a phase of ‘system acceptance’ – essentially, ensuring the super sewer and its associated infrastructure functions as designed.

And as part of this, Tideway is seeking to partner with a contractor to undertake in the order of 3,000 planned maintenance activities per year across 21 London sites, on MEICA and civils assets located at the surface and just below.

The contractor will also be responsible for any reactive maintenance activities.

Andy Forestiero, Tideway’s Systems Performance & Maintenance Manager, said: “We’re entering a new phase of works on Tideway as we continue toward our ultimate goal of cleaning up the River Thames for generations to come.

“And with this change of emphasis comes new opportunities. We’re fortunate to have worked with some world-class contractors on this job and I look forward to engaging with the market again to fulfil this unique opportunity.”

Assets that fall within the scope of this maintenance contract include ventilation equipment, pumps, penstocks, electrical equipment, instrumentation, civils structures, and more.

The super sewer’s main tunnel, its connection tunnels and shafts are not included in the scope of this contract.

Tideway is set to issue a pre-qualification questionnaire with more information available at procurement@tideway.london
