Q-decking is being shot down to the steel beams of the third floor. The decking provides a stay-in-place form for the concrete slab of the third floor.
Along the west side of the first floor, concrete block is being put in place by masons working for M-Fal Masonry. The retaining wall of the parking deck is behind the concrete block (seen here).
The first floor mechanical, electrical and plumbing work is ongoing.
