Anglian’s @one Alliance: delivery model and digital workflows for water project teams
Reviewed by Tom Sullivan
First reported on New Civil Engineer
30 Second Briefing
Anglian Water’s @one Alliance is profiled for its integrated delivery model on large water and wastewater schemes, where designers, contractors and the client work as a single organisation under long-term framework agreements. The discussion focuses on programme-wide standardisation of treatment plant components, use of digital twins and 4D BIM for sequencing, and early contractor involvement to reduce rework on complex pipeline and pumping station upgrades. Engineers listening can benchmark alliancing approaches, risk allocation and digital workflows against their own capital delivery programmes.
Technical Brief
- Lessons on alliancing are increasingly referenced by other UK regulated utilities when reshaping AMP delivery models.
Our Take
Within the 117 Infrastructure stories in our database, Anglian’s @one Alliance stands out as one of the few long-running alliancing models repeatedly cited by UK practitioners as a benchmark for integrated client–contractor delivery.
Among the 286 tag-matched ‘Projects’ and ‘Sustainability’ pieces, most water-sector items focus on regulatory pressure or asset failure, so a delivery-focused case like Anglian’s @one Alliance offers rare practical insight into how governance and commercial structures can actually embed sustainability outcomes.
For utilities looking to replicate Anglian’s @one Alliance approach, our coverage suggests that alliancing models tend to gain most traction where capital programmes are multi-year and geographically dispersed, allowing partners to standardise design and delivery methods across many small to medium schemes rather than a single flagship project.
