The long-awaited removal of the exterior-mounted tower crane at the Cityzen Development GroupFernbrook Homes and Castlepoint Numa's L-Tower is finally complete. The process of removing the crane began at the start of May, and in the couple of weeks since, several of our Forum contributors have been documenting the milestone event for the 58-storey Studio Daniel Libeskind-designed condominium tower.

In a complex process, sections of the crane's mast were removed one by one with the help of a steel jacket fixed to the crane cab and jib assembly, seen in red in the photos, allowing the individual mast sections to be removed as it slowly slid down the mast and surrounded them. After each section of the mast was lowered to the ground, the red housing slide down a couple more floors and the process was repeated.

The final stages of the crane removal involved the closure of an eastbound lane on The Esplanade between Yonge Street and Scott Street, allowing the mobile crane seen below to lower the last elements of the tower crane down to street level.

By the afternoon of May 18, the entire crane had been dismantled, with just a temporary derrick left standing atop the tower. The derrick will be used to lift the Building Maintenance Unit into place. When it is operational, the BMU will then lower the derrick in sections to the ground.
