What we were asked to do

Gateway Village's central kitchen supports a large workforce in Port Hedland. Compass Group needed the HVAC system decontaminated and brought back to a verified clean baseline - without taking the kitchen offline. Disruption-free delivery was the brief.

The challenge

What made this one hard

  • Live operations: thousands of meals served daily, no downtime acceptable
  • 16+ operational zones with overlapping schedules
  • Heavily contaminated duct interiors with microbial growth and biofilm
  • Compliance evidence required to AS/NZS 3666 and manufacturer specification

Our approach

How we delivered it

  1. Zone-by-zone sequencing across 16+ operational areas
  2. Sectional isolation of the duct run under works
  3. Overnight and shoulder-window scheduling around meal services
  4. Coil cleaning, duct decontamination, antimicrobial treatment
  5. Full encapsulation of the duct system to lock the result in
  6. Photo-documented evidence per zone

Equipment & methodology

  • Negative-pressure HEPA rigs
  • Brush-and-vacuum duct cleaning systems
  • Antimicrobial fogging equipment
  • Borescope cameras for verification

Outcome

What changed for the client

  • 16+ zones decontaminated across nine months
  • Zero kitchen service interruptions
  • Documented evidence pack handed to Compass HSE and site management
  • Recurring scope confirmed for ongoing intervals
Recurring HVAC + Mould + IAQ
