The Northern Beaches State High School project presented a significant challenge, as it involved working within an operational school environment to upgrade the existing air conditioning systems. The scope of work included the replacement of packaged air conditioners with cassette and high wall split systems, as well as retrofitting existing units in the manual arts building and installing new package air conditioners across various classrooms and spaces. It's important to note that all activities were carried out in strict adherence to the Department of Education's specifications.
