Since celebrating its official topping off ceremony back in December, construction of First Gulf's Globe and Mail Centre has continued to make progress. The 17-storey Diamond Schmitt Architects-designed office tower recently reached yet another milestone, with the disassembly of the development's two tower cranes.

Crane removal began this past Friday, starting with the south crane. It's painted blue and white in the image above from March 6. By the time UrbanToronto Forum contributor Razz got shooting on Friday the 18th, the jib, counterweights, counterjib, rear and fore pendants, the trolley, and the tower peak were already all gone. In the image below, the operator's cab was in the process of being hooked onto the north crane, ready to be lowered.

After being hoisted down to Berkeley Street—which was still open to other traffic during this operation—the sections of crane were loaded on to flatbed trucks to be carted away to the next job site.

By the close of the work day on Friday, the south crane was fully disassembled, with work primed to start on the north crane's removal the next day.

Disassembly of the north crane commenced the following morning. To accomplish this, a temporary hydraulic crane was parked on Berkeley, with this block of the street closed to traffic for the duration of the removal.

First, the mobile crane was used to remove the horizontal jib, starting with the counterweight slabs and followed by the jib arm itself. In the image below, the tower peak, the counterjib and the rear pendant remain.

After those sections were also removed, the north crane's swivelling slewing ring and operator's cab were next to be detached, leaving just the main tower section/top climbing unit in place above the building's mechanical penthouse.

The last major sections of crane to be removed were the climbing units of the mast. They work together during construction to raise the crane to higher floors as the building grows taller over the course of construction.

Following the removal of the north crane, the temporary crane used for the operation was disassembled itself. This procedure required the closure of Front Street to traffic as well as Berkeley.

The completed Globe and Mail Centre will soon add 500,000 square feet of office space to King Street East, and will be home to more than 3,000 employees upon opening. The development is targeting LEED® Gold with a number of energy efficiency features including a high-performance glazing system with ten-foot-high windows that allow daylight to penetrate deep into the building's core.
