In a traditional procurement model, a mechanical engineer designs the HVAC system, the client tenders that design to contractors, and if the installed system does not perform, the accountability is disputed between designer and installer. Design and construct removes this gap. QPT takes a performance brief, develops the technical design, and takes responsibility for both the design and the installed outcome.

For clients who want clear accountability and fewer coordination interfaces, D&C is typically the better procurement model for mechanical services in Brisbane commercial projects.

QPT works with clients to develop a clear performance brief that defines the temperature, humidity, air quality, and energy efficiency requirements the HVAC system must meet. This brief becomes the basis for the D&C specification and the commissioning performance targets.

For HVAC design and construct in Brisbane commercial buildings, QPT’s internal design capability covers load calculations, equipment selection, ductwork and pipework design, controls strategy, and energy compliance modelling for NCC Section J or NABERS as required.

QPT manages procurement, delivery, and installation of all mechanical services including air conditioning, ventilation, pipework, controls, and BMS integration. Programme management and coordination with other trades is managed within QPT’s project delivery team. For mechanical design and construct in Brisbane, QPT’s combined electrical and mechanical capability means both scopes can be delivered under a single D&C contract.
