The Moits team encountered numerous challenges whilst undertaking the Bays Station Box excavation. As part of Moits’ excavation package, we utilised telescopic attachments, long-reach excavators and D475 dozers to address the restrictions associated with confined station box operations.

The project’s 24-hour shift cycle, including continuous handovers between day and night crews, was managed without mishap, resulting in seamless operational continuity. Working through night shifts in a reduced-visibility environment introduced additional complexities, which were mitigated through advanced planning, enhanced fatigue management strategies, and rigorous supervision.

Dust suppression was a crucial environmental control measure, with the deployment of sprinkler systems and dust cannons to maintain air quality in line with regulatory standards. Close coordination with AFJV was pivotal, particularly when working alongside other subcontractors to allow for the installation of rock anchors and shotcrete.

Dewatering presented a particularly complex obstacle, requiring detailed assessments and the consideration of multiple methods, including spears and well systems. Given the atypical site conditions, a collaborative approach with AFJV was critical to refining a dewatering methodology that effectively mitigated groundwater ingress.

Despite these challenges, the project was executed with zero Lost Time Injuries (LTI), Medical Treatment Injuries (MTI), First Aid Incidents (FAI), environmental harm, or other incidents. This technical partnership enabled Moits to complete the project successfully, overcoming substantial environmental and operational constraints and delivering a safe and efficient outcome.
