Collins Arch, 447 Collins Street

A $1.25 billion, full-city-block transformation presented unprecedented safety management complexity with simultaneous basement excavation, high-rise construction, heritage interface, and CBD public protection requirements.

The scale of the project—combining premium office, luxury residential, and ground-floor retail—meant managing multiple high-risk activities concurrently across confined CBD site boundaries with significant public interface exposure.

Coordinating safety across basement excavation, tower construction, and façade works simultaneously in a confined CBD site required sophisticated staging and separation of high-risk activities. The project's architectural complexity, including innovative façade systems, demanded specialized technical safety reviews beyond standard audit protocols.

Elliott Safety established a comprehensive monthly HSE audit program supplemented by specialized high-risk work reviews and façade rectification oversight as the project evolved.

Our incident investigation capability and monthly reporting gave Multiplex and stakeholders continuous visibility of safety performance across this five-year landmark development.
