The client had been waiting over a year for their faulty air conditioning units to be replaced, but due to the lack of suitable access for a traditional crane, it was not possible to replace the units without the assistance of a helicopter crane. So our BK117 twin engine helicopter was the most suitable option.
The property is located high on a hill with waterfront access, so delivery of the new air conditioning units, and removal of the faulty ones was able to be done by barge on the water.
As with many Sydney jobs, the property was located inside controlled airspace, so permission was required from Air Traffic Control to conduct the lift between commercial airline operations at Sydney Airport. As always this requires careful planning, advance notification to ATC, and a small operational window that we were allowed to use for the lifting operations to be performed.
