Overview

What This Discipline Covers

HVAC sits at the intersection of our mechanical and electrical divisions — chilled water piping shares trades and standards with our process piping teams, while chillers, AHUs and controls tie directly into the power distribution and BMS installed by our electrical division. Keeping all three under one contractor removes the coordination gaps that usually slow HVAC installations down.

We size and select equipment against a proper heat load calculation rather than rules of thumb, route and insulate ductwork and pipework to minimise losses, and finish every installation with full testing, adjusting and balancing so the system actually delivers the comfort conditions it was designed for.

How The Process Works

From Site Survey to Handover

Every hvac works contract moves through the same disciplined sequence — so quality is built in at each stage, not inspected in at the end.

01

Heat Load Calculation & System Selection

Cooling and heating loads are calculated room by room to size chillers, VRF/VRV systems, AHUs and duct routing correctly, rather than oversizing on assumption.

02

Ductwork & Pipe Fabrication

GI, pre-insulated and stainless steel ductwork is fabricated, and chilled water pipe is spooled, in parallel with civil and structural progress.

03

Installation & Insulation

AHUs, FCUs, chillers and ductwork are installed and hung, and pipework and ductwork are insulated to prevent condensation and thermal loss.

04

Testing, Adjusting & Balancing (TAB)

Airflow at each diffuser and water flow at each coil is measured and adjusted until it matches the design figures, not just "turned on and left".

05

Commissioning & Handover

Chillers, AHUs and controls are commissioned against design duty points, and O&M manuals and as-built drawings are handed over with operator training.

Detailed Scope

Scope / 01

Centralized Air Conditioning

Chillers, VRF/VRV systems and packaged rooftop units are selected against the calculated load and installed with the mechanical, electrical and controls interfaces coordinated up front.

  • 01Equipment is selected and scheduled against the heat load calculation.
  • 02Units are positioned, set on isolators and connected to power and controls.
  • 03Refrigerant or chilled water circuits are commissioned to design duty.
Insulated chilled water pipe routing

Scope / 02

Chilled Water Piping

Precision-routed, insulated chilled water piping is drawn from our own supply chain and installed by the same certified fitters who install our process piping, keeping weld and joint quality consistent across both scopes.

  • 01Pipe routing is coordinated with structure, ductwork and other services.
  • 02Pipe is welded or jointed, pressure tested, then insulated and vapour-sealed.
  • 03Flow is balanced at each coil during system commissioning.

Air Distribution & Ducting

GI, pre-insulated and stainless steel ductwork, complete with diffusers and dampers, is fabricated and installed to deliver conditioned air evenly through every space.

  • 01Ductwork is fabricated to the design layout and duct sizes.
  • 02Sections are hung, sealed at joints and insulated where specified.
  • 03Diffusers and dampers are fitted and set for the required airflow pattern.

Scope / 04

Ventilation & Exhaust

Fresh air handling, car park ventilation, kitchen extract and smoke management systems keep air quality and life-safety performance where they need to be, in both normal and emergency operation.

  • 01Fans, louvres and grilles are installed per the ventilation design.
  • 02Ductwork and fire dampers are fitted at compartment boundaries.
  • 03Normal and smoke-mode operation are function-tested with the fire system.

Testing, adjusting and balancing works
Scope / 05

Equipment & TAB

AHUs and FCUs are installed and then put through full testing, adjusting and balancing, so airflow, water flow and temperatures are verified against the design — not assumed.

  • 01AHUs and FCUs are installed, wired and piped to the system.
  • 02Airflow at diffusers and water flow at coils are measured on site.
  • 03Dampers and valves are adjusted until readings match the design schedule.
