A project to replace the gallery’s roof-based heating, ventilation and air conditioning (HVAC) equipment will see a helicopter lifting operation hoisting materials on to the roof.
The work is scheduled to take place over two hours on Saturday morning, with a provision to switch to Sunday if weather conditions are not favourable.
The helicopter will visit the site again on July 2 and August 6, while a crane will be in operation for some heavier equipment on June 21.
Using the helicopters was identified as the most cost-effective and efficient way to get the heavy materials on to the roof. The three planned operations are expected to cost a total of $45,000.
The crane will cost $25,000 for the day it is used.
Dunedin City Council property services group manager Anna Nilsen said replacing the HVAC equipment was an important part of looking after the artworks in the gallery’s care.
"The art gallery is home to an internationally significant collection, and temperature and humidity control is essential for its care and protection."
Members of the public were welcome to observe the helicopter in action, but were asked to maintain a safe distance from the work site.
