Lot 2: Sewer rehabilitation inc. CCTV and cleaning above c.£3m and/or complex

Companies may 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.

Thames Water reserves the right to refine the award criteria.

Published description of the framework

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 Construction Short form Contract (ECSC) for Lot 1 and, NEC4 Engineering and Construction 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.

What this means for your bid
  • Price carries 40 of 100 points: a 10% discount moves about 4 points. The method statement decides this lot, not the discount.
  • “Sewer Rehabilitation inc. CCTV and Cleaning” is a framework: the contest is a place on its panel, not a single contract: call-offs may be direct or by further competition.

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
