The Client
Broad is a national construction company recognised for delivering complex, large-scale commercial developments across Australia. With a history spanning decades, Broad has earned a reputation for its ability to manage demanding timelines while upholding rigorous quality standards.
Envar’s partnership with Broad began in 2011 during the Western Power Building Refurbishment Project. Over nearly a decade of collaboration, the relationship has been defined by trust, technical excellence, and a shared commitment to delivering high-performance building systems. This latest project continued that tradition, with Broad appointing Envar to deliver the complete mechanical services solution for a new greenfield development.
What we achieved with our customer
The $6m project centred on the design and installation of a central energy plant and backbone services to the entire building, ensuring a fully integrated mechanical services solution. Envar’s scope included the installation of chillers, boilers, pumps, associated pipework, full building ventilation, and integration with the Building Management System (BMS).
To meet the demanding program, Envar introduced on-site prefabrication using the Victaulic roll groove pipe system. This approach reduced installation time, improved accuracy, and enhanced safety by minimising on-site welding and hot works. The prefabricated sections were assembled and tested in controlled conditions before being transported to site for final installation.
Close coordination with Broad’s project team ensured that plant deliveries, lifting operations, and installation sequences were seamlessly aligned with other trades. This collaborative approach prevented bottlenecks, optimised crane use, and allowed work to progress without interruption.
By leveraging prefabrication and precise planning, the project was completed on schedule, within budget, and in full compliance with the building’s mechanical performance requirements. The result was a robust, energy-efficient mechanical services installation designed for long-term reliability.
