In March, work will begin to deconstruct the Harbour Control Tower in Barangaroo Reserve.
The concrete and steel tower, which was built in the 1970s to oversee shipping movements in Sydney Harbour, has been redundant since 2011 when the Port Authority of NSW transferred vessel monitoring operations to its base in Port Botany.
Removal of the 87m-high concrete and steel tower is part of the overall vision to restore a naturalistic-looking headland to Barangaroo Reserve.
The headland park will remain open for public enjoyment throughout the deconstruction process.
Only small areas directly around the tower at Barangaroo Reserve and inside the Cutaway will be closed to the public while the work is carried out.
Ensuring the safety and wellbeing of visitors, nearby residents and workers as well as minimising inconvenience were of paramount concern for the Barangaroo Delivery Authority when considering how best the Harbour Control Tower could be removed. The deconstruction method includes the erection of a moveable working platform and use of remote controlled demolition robots to pulverise the concrete structure. The deconstruction will be achieved with minimal disruption, dust, noise and vibration. The stainless steel, concrete and glass observation area atop the 87m-high tower will be deconstructed by hand and either removed via a construction hoist or mobile crane. It is anticipated this stage of the demolition process will take approximately four months.
Once the top section of the building has been removed, remote-controlled demolition robots will be used to “eat away” the tower itself, with the debris pushed into the tower’s shaft and taken offsite at the Cutaway level.
Over a period of approximately three months the tower will gradually diminish to the Cutaway level.
Finally, the concrete footing will be fractured, removed, and remediated.
The whole process will take approximately nine months and is scheduled for completion by the end of 2016.
Approved hours of operation for construction works are from 7:00am to 6:00pm Monday to Friday, and 8:00am to 3:00pm on Saturdays.
