Case Study: Costain improves coordination across 25 projects with Aphex

Costain manages 25 projects and up to £2 billion of work with Aphex

Costain, a major UK infrastructure company, faced significant coordination challenges while managing 25 concurrent water treatment projects for Thames Water. The pre-construction phases—including design, procurement, and early contractor involvement—were siloed from construction planning, leading to missed start dates and resource conflicts. To gain control over this complex, multi-billion pound framework, Costain partnered with Aphex to implement its construction planning and coordination platform.

Using Aphex, Costain extended its proven weekly construction planning discipline into the pre-construction phase, creating a single source of truth for all deliverables. The solution provided framework-wide visibility through integrated dashboards, enabling systematic performance tracking and transparent weekly progress sharing with the client. As a result, Costain improved cross-phase coordination, built stronger client relationships through transparency, and established a new standard for program reliability, leading them to mandate Aphex for all future pre-construction programs.
