What we design and deliver.

Full mechanical services from load assessment through to IFC drawings, specs, and commissioning support.

🌡️

ACMV System Design

Air conditioning and ventilation design for commercial, retail, industrial, and institutional buildings. VRF, chilled water, split systems, and hybrid options.

💨

Outside Air & Exhaust

Outside air sizing, exhaust airflow design, and pressurisation to AS/NZS 1668.1 and 1668.2. Covers toilet exhaust, general exhaust, and supply air systems.

🔥

Smoke Exhaust & Pressurisation

Smoke exhaust design for atria, carparks, and open-plan floors. Stairwell and lift shaft pressurisation to AS/NZS 1668.1 and NCC rules.

📊

Thermal Load Assessments

Whole-building and zone-by-zone thermal load calculations. We account for walls, roofs, occupancy, equipment, and sun exposure.

Energy Modelling

NCC Section J compliance modelling and DTS pathway checks. Energy modelling to support NatHERS, NABERS, and Green Star targets.

🏭

Plant Sizing & Layout

Chillers, boilers, cooling towers, AHUs, and FCUs. Sized for the load, laid out for easy maintenance, and coordinated with structure and other services.

🖥️

BMS & Control Strategies

BMS point schedules, control narratives, and sequence of operations. Built for energy savings, easy maintenance, and fault finding.

🚗

Carpark & Kitchen Exhaust

Carpark ventilation with CO and NO₂ demand control. Kitchen exhaust with make-up air, grease filters, and heat recovery options.

📋

Ductwork, Pipework & Insulation

Fully sized ductwork and pipework schedules with insulation specs. Designed to reduce pressure drop, noise, and energy use.

Designed to the standard. Certified with confidence.

All our mechanical designs follow NCC 2022 and the AS/NZS 1668 series. We include compliance reports with every project. We also provide certification when the certifier or consent authority needs it.

Systems that balance comfort, cost, and compliance.

Good mechanical design is not about picking the most expensive equipment. It is about choosing the right system, sizing it correctly, and documenting it clearly so a contractor can install it without guesswork.

We run thermal load calculations from first principles. We plan plant room layouts early to avoid clashes with structure. We write control sequences that operators can understand and maintain.

  • Right-sized systems, not over-engineered
  • Plant rooms designed for maintenance access
  • Control strategies that are easy to operate
  • Energy performance verified at design stage
