Our Approach Overview


Within the building industry, our name is frequently associated with iconic construction, dating back to our initial Australian project installing the HVAC&R for the Sydney Opera House.

Haden (formerly Haden Engineering) are one of the few mechanical contractors cleared to work on sensitive areas of Defence projects in Australia. We actively seek out work that offers challenges to the way we design and think about building services.

This has led to us being involved in a diverse range of contracts:

  • entering into a public private partnership (PPP) with the NSW Government in the redevelopment of a large regional health care facility including administration offices, surgeries, theatres, laboratories, treatment rooms, circulation areas, emergency facilities and accommodation
  • developing highly complex systems to protect exhibition artefacts and provide comfort to patrons for a national museum
  • working closely with a water treatment supplier to develop a treatment regime to retain water in the system longer, resulting in significant water consumption savings and raising the building's Green Star rating
  • being involved in highly rated NABERS and Green Star building projects
  • establishing offshore bases to service projects in remote locations
  • designing environmental efficiencies into upgrades and refurbishments.
