Framework operation description

Thames Water Utilities Limited is establishing this Framework as a two lot, multi-supplier framework agreement for the delivery of Sewer rehabilitation, and associated CCTV and Cleaning works.

The Framework will be procured using a competitive flexible procedure.

General operation of the Framework - as per tender documents

No supplier is guaranteed any minimum volume or value of work under the Framework.

Call-off contracts will be awarded either:

• through further competition between all appointed Framework suppliers within a Lot; or

• via award directly to a supplier on a proportional allocation basis

For each call-off, Thames Water Utilities Limited will issue a call-off tender pack setting out:

• the initial scope of works,

• project-specific requirements and constraints,

• pricing approach and assumptions, and

• evaluation criteria.

Tenderers will be required to submit both a technical and commercial proposal. Contracts will be awarded to the tenderer submitting the most advantageous tender in accordance with the criteria set out in the call-off documentation.

Call-off contracts will be let using the NEC4 Engineering and 91º»ÏÈÉú Short form Contract (ECSC) for Lot 1 and, NEC4 Engineering and 91º»ÏÈÉú Contract (ECC) Option B (priced contract with a bill of materials) or Option D (Target Costs contract with a bill of materials).

Pricing mechanism

At the framework award stage (ITN), tenderers will be required to submit a Framework Schedule of Rates, setting out their proposed:

• labour rates,

• plant and equipment rates,

• daywork rates, and

• fees

These rates will form the baseline pricing structure for all future call-off contracts under the Framework.

At call-off stage the rates agreed within the framework contract will form the maximum rates permissible for call off contracts under the framework.

Call off contract pricing will be established via a request for proposal process under the framework.

Award method when using the framework
