Roughly ten weeks since the installation of a tower crane at the northeast corner of the excavated pit, construction crews from Tucker HiRise are working away on the below-grade levels of MOD DevelopmentsMassey Tower, a sleek, 60-storey Hariri Pontarini Architects-designed condominium tower under construction at the rear of the 1905-built Darling & Pearson Architects-designed Canadian Bank of Commerce Building.

Since the complex operation of pouring a 3-metre thick raft slab foundation and the subsequent installation of a tower crane, crews have been busy forming the thick reinforced concrete foundation walls that will eventually support the 60-storey tower to rise above, as well as the below-grade structures for the tower's basement levels.

At approximately 1 metre in thickness, the heavy foundation walls taking shape around the perimeter of the pit will soon be secured to the tiebacks visible in the images above and below, anchoring the foundation levels to the surrounding ground.

Though concrete is currently being poured in from the perimeter of the site, footings are now in place for a concrete pump at the base of the pit.

In response to the narrow footprint of the site, Massey Tower's below grade levels will house the building's servicing area, while parking will largely be hidden in the podium levels and not visible to passersby, accessed by residents via a car elevator and stacking system.

The Massey Tower was excavated in tandem with neighbouring KPMB Architects-designed $135 million Massey Hall addition. The project, which is being built on a 4,800 square foot footprint donated to the Hall by MOD Developments, has also progressed significantly since our last update. Excavation of the site is complete, and foundation work has since begun. A crane base was recently installed for the project's upward construction, though significant above grade construction on the addition will not begin until the Massey Tower is largely complete, as access by construction equipment and for materials to its site is necessary.

For a better understanding of how the current stage of work fits into the overall project, Tucker Hi-Rise has produced a video showing how the tower will be constructed from start to finish.
