Case Study: John Holland and Seymour Whyte unify project planning with Aphex

How John Holland and Seymour Whyte keep hundreds of engineers on the same page

The John Holland Seymour Whyte Joint Venture faced a major challenge coordinating the complex Sydney Gateway infrastructure project, which involved navigating extreme constraints and interfaces with busy roads, a rail line, and a regulated airport precinct. Their existing processes, reliant on manually formatted spreadsheets for lookahead planning, were pushed beyond their limits and risked significant delays. They turned to the vendor Aphex to implement a single platform for managing their lookahead plans and driving a "one team - one plan" approach.

By implementing Aphex, the project replaced their fragmented spreadsheets with a single, connected digital plan aligned with their master program. This provided a unified platform for over 150 engineers to collaboratively break down work, standardize planning routines, and hold real-time coordination meetings. The results included consistent, automated weekly progress reporting, a leaner planning team, and a better understanding of delay drivers, empowering the entire team to spend more time on delivery rather than administrative tasks.
