Construction work for water and sewage pipelines

Tender description

Variation to the detailed arrangement for Thames Water’s Infrastructure Alliance. Thames Water considers that the variations do not affect the nature or scope of the original Alliance agreement and contracts. Variation to an existing Alliance Agreement dated 29.1.2015, relating to the Infrastructure Alliance and the variation to the 2 related Alliance Contracts entered into on that same date with each of the Alliance Members. The original agreement and contracts were entered into under a contract notice reference 2014/S 122-218174. The Alliance has been running for 3 years of AMP6 and the variation follows a review of how the Alliance operates in line with the key Alliance principle to seek continuous improvement in the way it operates. The following variations to close out year 3, and for years 4 and 5 of AMP6, are being implemented: 1. clarification on how the Head of Networks works for the Alliance Board; 2. using a schedule of rates for payment in Developer Services to better fit with Thames Water’s published new charging arrangements for Developer Services; but these rates are still based on actual cost and the same management fees include in the original contact and the rates are reviewed each year against actual cost and management fee. New service levels have been set to meet developers' expectations on service delivery; 3. revision of budget levels for clean water networks following a review of the Costed Needs from the business plan; changes to the Costed Needs being envisaged in the original Alliance Agreement; 4. revision of programme-level pain / gain mechanism linked to Thames Water’s performance across Outcome Delivery Incentives (ODIs) and Service Incentive Mechanism (SIM) to more closely reflect those individual measures the Alliance Members can directly influence; and to incentivise timely performance of leakage jobs service levels have been included; 5. updating of the contracts for changes in law including CDM Regulations, GDPR, Modern Slavery Act and Part 3 of Criminal Finances Act.
