One contract. One team. Concept to commissioning.
HWM is a fully integrated engineering, fabrication and construction company. We take a project from initial design brief through detailed engineering, fabrication, precision machining, and site installation — without handing off to a third party at any stage. The result: reduced interface risk, a single point of accountability, and a partner who understands the full scope from day one.
Detailed engineering, FEA, fitness-for-service
Structural steel, vessels, tanks, piping, skids
Precision CNC for critical tolerances
Site delivery, install, handover

Design, fabrication, machining, installation and commissioning under one contract. No hand-offs, no interface risk.
API 579 / ASME FFS-1 fitness-for-service, FEA modelling and remaining-life assessment — beyond fabrication.
Precision machined components produced in-house alongside fabricated assemblies — no outsourcing for critical tolerances.
ISO 9001/45001/14001, AS/NZS ISO 3834 Pt 2, SCA CC3. Capability to mobilise across metro, regional and remote locations nationally.
Named, credentialled leadership. The technical depth competitors rarely surface on a homepage.
