REMARKS: AAI Engineering conducted a site visit to observe the progress of the structural
work on Building B. We walked the site and reviewed the general framing, shearwall
sheathing /nailing, roof diaphragm nailing, anchor bolt placement, wall and roof strapping, and
hold downs.
At the time of the site visit, the majority of the abovementioned items were complete. Some of
the vertical strapping at the north wall line, (grid A), was pulled away to permit the final field
welding of the HSS Headers to the steel columns and the storefront framing at the south wall
line was in progress. The observed work appears well- constructed and in general
conformance to the design drawings with the following exceptions and /or notations:
1. The contractor requested a repair for (3) HSS5x5 baseplate connections at the north wall
line, (grid A), where the anchor bolts were installed without sufficient extension above the
top of the footing to permit the nuts to be installed. See the attached SK -1, dated 1/9/09
for a revised connection. •
2. The anchor bolts are installed for the HDQ8 corner hold downs, however, the holdowns
are not yet installed. AAI verified that HDQ8 hold downs were required at these locations.
In some cases, the threaded rod extension above the top of the footing appears as though •
it will be too short to permit the installation of the required hold downs. A coupler +threaded
rod (same diameter as anchor bolt) may be installed and the hold down can be installed
• above the sill plate. The coupler connection shall be capable of developing the full
capacity of the anchor bolt and the threaded rod.
3. Several sill anchor bolts are too close to wall studs to permit the nut and washer to be
installed. At these locations, the stud may be notched to permit the installation of the
washer and nut.
4. The 2 " layer of shearwall sheathing will be added to wall types E and F once the work
inside the walls is complete.

5. The anchor bolt spacing at wall types B along grid C appears to exceed 16" in some
locations. The contractor should confirm the installed anchor bolt spacing for each wall
type and, if the spacing exceeds the maximum specified in the shearwall schedule, install
additional A36 5/8" diameter (5" embed) threaded rods with Hilti HY -150 epoxy as
required.
6. The (2) 2x6 at the shearwall panel joint between grids B and C along grid 5 shall be nailed
together with (2) rows of 8d at 8" o.c. each face, staggered.
7. The LTT19 ties per detail 10/S5.1 were not installed along grid 5 due to interference from
the column caps. At these (2) locations the LTT19 may be raised and installed at the side,
into the web, of the blocking. Provide additional plywood on the side of the web to achieve
full penetration of the LTT19 nailing and increase the length of the lag screw by 1.5 ".
NOTE: An additional HTS16 is required across the bottom of the first joist in all cases as
the LTT19 is not long enough to connect the 1 and 2" bays of blocking as shown on
detail 10/S5.1.
8. All of the roof joist strap ties across the glulam girders appeared to be LSTA18 straps per
detail 4/S5.1. At the 6 joist in from each end, a ST6224 strap should be used per keynote
3 on S2.1. Contractor to verify and install new ST6224 strap if required.
The contractor shall provide a written statement and any required photo documentation stating
that all the necessary repairs have been completed prior to AAI Engineering issuance of a
Final Compliance Letter.
