Who We Are
Built on Experience, Forged in Western Australia
Rimech Engineering launched in Western Australia in 2022, building on the solid foundation of Brian Duignan Engineering — established in Ireland in 2015. After gaining deep experience across Victoria, New South Wales, and Queensland from 2010 to 2014, founder Brian Duignan returned to Australia and officially opened Rimech in early 2023.
Today, Rimech is a leading structural, mechanical, and pipework contractor serving Perth metropolitan and the Goldfields regions. We specialise in steel pipe and structural fabrication, installation, mechanical works, HVAC, and ducting installations — delivering with precision across Western Australia's most demanding industrial sectors.

The Principles That Drive Every Project
Safety First
Every decision, every process, and every project begins with the safety of our people and yours. ISO 45001-aligned systems ensure compliance is never compromised.
Data-Driven Delivery
Our proprietary RMS platform captures real-time field data — giving clients in Perth and across WA daily visibility into performance, quality, and progress.
People Excellence
The best results come from the best people. We invest heavily in labour vetting, continuous training, and genuine staff support to build crews you can trust.
Integrity & Accountability
We stand behind every weld, every install, and every report. Transparent communication and honest delivery define how we operate.
WA's Most Trusted SMP Partner
We aspire to set the standard for accountable, data-driven project delivery in Western Australia. Through our Rimech Management System, we provide clients with daily visibility into team operations, performance metrics, and progress tracking — redefining what transparency looks like in engineering.
Our goal is recognition as Western Australia's most trusted SMP partner — characterised by lean delivery, workforce excellence, and an integrity-driven culture that puts results and relationships first.
