QEG was founded in 2009 to provide independent mechanical services advice clients could actually rely on. Seventeen years later, the practice has grown into a five-discipline engineering firm — but the original principle is unchanged.
The engineer who designs your system is the engineer accountable for handing it over. No competing trades, no hidden margins, no finger-pointing on commissioning day.
This document is a brief introduction to what we do, the projects we've delivered, and the standards we hold ourselves to. If anything here speaks to a project you're scoping, we'd welcome the conversation.
QEG is an Australian building services engineering firm. We deliver mechanical, HVAC&R, and gas turbine inlet cooling systems for buildings and plants where uptime is not negotiable.
Founded in 2009 by Robbert Frielink — a mechanical services engineer with two decades of design and construction experience. The original brief was simple: provide independent advice clients could actually rely on.
Seventeen years later the practice has grown to cover design, construction, pre-fabrication, gas turbine inlet cooling, and 24/7 critical-plant maintenance. The thread connecting it all: end-to-end accountability.
Single-source delivery — concept through commissioning, one accountable team. The team that designs the system is the team that fabricates, installs, and proves it under load.
Skid-mounted plant assemblies built offsite — installed and proven in days, not weeks. Best where shutdown windows, site access or weather are constraints.
Planned and reactive service for critical mechanical plant. 24/7 response, condition-based scheduling, full digital records.
Gas turbine inlet cooling. Lower the inlet temperature, lift the power output. Evaporative and chiller-based systems, retrofit and new install.
Mechanical services design, peer review and expert input for clients who need an experienced second set of eyes — or a primary one.
End-of-life central chilled water plant at a heritage CBD building required full replacement. Abacus Property Group needed a design and construct partner who could deliver without disrupting tenants or compromising the building's heritage character.
QEG was engaged on a Design & Construct basis. Leveraging its proven delivery methodology — weekly progress reports, proactive stakeholder communication, and close coordination with the original design consultant — the replacement was completed on time and on budget.
"From the initial report through to project delivery and completion, Quantum Engineering Group exceeded our expectations at every stage. With respect to performance of the plant, we'll let the stats do the talking." Carlos Olivares · National Engineering Manager · Abacus Property Group
