Those present walked the project site to review portions of the current construction. Work was ongoing throughout
the building. The following was noted:
1. Shoring posts had been installed at the first floor north retaining wall, in preparation for existing brace removal,
and they appeared to be in conformance with the phasing plan. See Picture 1.
2. In preparation for installing the shotcrete walls, braces and gusset plates were being removed from the
existing braced frames on Grids 2.7, 3, and 5. See Picture 2.
3. Existing braced frame base plate connections to concrete footings were observed at Grid locations C -7, C -8,
and C -9. See Picture 3. It was observed that some anchor bolts were missing nuts, and some base plate
holes were without anchor bolts. Braced frame gusset plates are receiving new anchorages that have been
designed to resist the entire load demand; therefore, new nuts /bolts are not required to fill the absence of the
existing missing nuts /bolts.
4. Multiple areas in the third floor composite concrete over metal deck had been chipped or cored to expose wire
mesh reinforcement and welded headed studs. See Pictures 4 and 5. At both chipped locations, the wire
mesh was found to be near the bottom of the topping slab, located within 1 /2" from the top flute of the metal
deck. Mesh located this low in the topping slab will reduce the reinforcement's ability to minimize cracking at
the surface of the concrete, and this may be one explanation as to the increased amounts of cracking in the
elevated slab. Also, Kyle of HSW, who performed the concrete chipping, explained that the concrete was
relatively easy to chip out compared to previous experience with concrete chipping. This indicates that the
concrete strength may not be very high; therefore, it may be beneficial to verify the in -place concrete strength
by taking concrete cores and having them tested.
Action Items
1. HSW will contact Carlson Testing to obtain information about concrete coring /testing.
