What Q H & M Birt does
Q H & M Birt is a privately held, family-owned Australian civil construction contractor specialising in bulk earthworks for the mining and government infrastructure sectors. Founded in 1973 by Quentin Birt and operating day-to-day since 1976, the company is headquartered in Toowong, Brisbane, with a second office in Perth. It delivers road, rail, mining, bridge, drainage, tailings storage, water storage, flood protection and haul road projects across Queensland, Western Australia, Northern Territory, New South Wales and South Australia.
The company's core capability rests on its 100% company-owned fleet of more than 460 machines — described as Australia's largest civil earthmoving fleet and including the largest scraper fleet in the southern hemisphere — complemented by GPS-equipped safety and survey technology and in-house maintenance. All project execution, from estimating and surveying through to construction and HSE management, is performed by directly employed management, engineers, operators, surveyors and maintenance staff, with no subcontracting of core earthworks. Recent reference projects include the $150M Eliwana Rail earthworks for Fortescue, the $140M Amrun Bulk Earthworks for Bechtel, the $80M Bruce Highway Cooroy to Curra Section D1 for the Queensland Government, and ongoing work for Rio Tinto (BS1 Mine Plant, Ima Ramp, Hope Downs 1), Northern Star Resources (Fimiston III TSF), South32 (GEMCO), CMOC (North Parkes E31) and Stanmore Coal (MRA2C).
Q H & M Birt generates revenue through project-based fixed-price contracts secured via direct tendering with major mining companies and government agencies, with pricing determined by project scope and scale. Distribution is exclusively direct enterprise sales; over half of annual work is repeat business from existing clients. The company holds Queensland Government prequalifications (Roadworks R3, Bridgeworks B2, Financial F150+) and ISO 9001, 14001 and 45001 certifications, which gate access to major public infrastructure tenders. Operations remain entirely domestic, with no disclosed M&A activity, no external funding rounds and no public financial reporting.
