Principal Contractors

Our extensive skills in the water and wastewater arena, along with experience, expert knowledge and the ability to deliver make UKDN Waterflow the premier water and wastewater infrastructure company for many principal contractors.

During decades of working alongside joint ventures, principal contractors and consultants, our track record includes the SDAC contract for Thames Water (TW), with Optimise — the joint venture (J Murphy and Sons, Barhale Construction, Clancy Docwra Ltd and MWH) delivering the five-year AMP5 contract for Thames Water.

Integrated Supply Chain

In this principal contractor relationship, we created an integrated supply chain with Flowline and Xylem to facilitate the delivery of TW’s required outcomes. The benefits of collaborative working and outcomes were achieved over a 14-month contract period. This included reduced cost per metre, improved customer outcomes (repeat blockage reduction and flooding other case reduction), increased asset knowledge and fast-tracked asset information creation.

The volume of resource required demanded a wider supply chain; however the objectives could not be achieved with a traditional supply chain approach, so we stressed that the status quo would not be tolerated and that partners would be chosen based on their approach to collaboration and willingness to commit to delivering the project outcomes. In return, training in the use of new systems and protocols was universally delivered, and over the duration of the contract, work volumes were varied between partners to reflect performance and support their wider business objectives where appropriate.

Benefits and risks

The financial benefits, and the risks, that are written into the contract underwrite this. In this case, the incentive for performance was volume of work and continuity, with poor performance objectively identified by project wide KPIs and applied to all delivery teams, irrespective of their parent organisation. Social aspects such as community engagement and customer satisfaction were included in the KPI suite as well as tradition time, cost and quality KPIs.

This contract and approach was commercially beneficial for all parties with reduced out-turn costs and improved customer outcomes for TW, and an unprecedented level of work continuity and the associated operating efficiencies achieved by the partner companies.

We are now the UK’s largest and most trusted infrastructure and drainage contractor with the resources and expertise to help you achieve your project outcomes.
