The water company is looking to put a framework agreement in place for a range of sewer rehabilitation, CCTV and cleaning works and services on gravity and rising mains across the entire Thames Water region, including:

Scope includes associated activities such as minor civil, inspection reports, waste disposal and street works.

The framework has been split into 2 Lots of work to reflect the variations in scale and complexity of rehabilitation services for different waste water assets and operational situations. Full scope of the services to be provided and any options that may be considered throughout the term of the agreement, is set out in the Standard Scope within the Invitation to Negotiate (ITN) document.

Interested suppliers are invited to apply for the following Lots:

Low value and/or non-complex CCTV, cleaning and / or sewer rehabilitation works on gravity and rising mains included but not limited to structural lining, pipe replacement, patch repairs, leak tight lining, pipe bursting and associated manhole sealing.

High value and/or complex programmes or projects planned CCTV, cleaning and / or sewer rehabilitation works on gravity and rising mains including but not limited to structural lining, pipe replacement, patch repairs, leak tight lining, pipe bursting.

Scope of works under both Lots includes associated activities such as civil works, manhole sealing, inspection reports, waste disposal and street works etc. Works will also involve elements of working on / in proximity of a railway (assessable to only those with required accreditations and required insurance levels).

The water company is looking to appoint up to six suppliers per Lot, with a maximum of 12 suppliers in total for the framework.

Companies can apply for one or more Lots - preference may be given in evaluation to those companies who demonstrate that they are capable of supplying a greater part of the overall requirement.
