The anchors supporting the mezzanine floor slab above the ground level men's toilet room are failing, likely due to a combination of inadequate embedment of anchors and minor shifting of the slab relative to the north wall. 2.

New waterproofing is required of the MacArthur Square slab to stop water penetration into the stairway vestibule and stairwell. 4.
