North Stairwell Structural Wall Repair - Phase 2

Contract 1: Bid Package 1 1. Water penetration in the stairway vestibule and stairwell has caused corrosion resulting in loss of section properties of the supporting angle. Though not visible, the anchors for this area are suspected for being corroded as well. Cracks in the wall adjacent to the vestibule door are likely due to shifting of the slab above the door and poor placement of reinforcement at the door jamb/header interface. 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. Provide a new structural support for the MacArthur Square slab above stairway vestibule and stairwell. Replacing the existing deteriorated supporting angle as the means of primary structural support. 3. New waterproofing is required of the MacArthur Square slab to stop water penetration into the stairway vestibule and stairwell. 4. To provide a new means of support for the mezzanine floor slab above the ground level Men's Toilet Room.
