RE: 8615 Pinebrook Street - Special inspection

NOTE:
This memo is to inform you of our observations and recommendations for
changes to our original engineering. We performed a site visit on
Wednesday. November 12. 2014 to inspect the installation of the epoxy
anchors. We also reviewed the framing for compliance with our design and
intent.
When we arrived the holes for the anchors had already been drilled. We
watched as they brushed and blew out the debris. We then verified the hole
sizes and the materials being used. We specified Simpson SET XP adhesive
epoxy. Next we watched as the epoxy was mixed to the proper color and
injected into the holes. The installation was per the manufacturers
specification and satisfactory with us.
We noted for the framing connection at the double top plate the rafters
were lapping with the ceiling joists and the HI connectors could not be
used. We recommend using a standard H2.5 hurricane ties each rafter.
The mudsill plate of the of the existing wall had 1/2" anchor bolts installed
but did not have the 3"x3" washer plates. It is acceptable to cut out the sole
plate to install the washer plates since the exterior sheathing is attached to
the mudsill directly. This should occur a minimum of five (5) places along
the side walls and three(3) places along the rear wall.
if you have any questions feel free to give me a call.

NOTE:
This memo is to inform you of our recommendations for changes to our
original engineering. It is our understanding the contractor would like to
substitute bolted holdowns in lieu of the STHD14 straps called at the front
wall of the house. Our shear wall schedule indicates the capacity of the
STHD14 is 3,640 lbs.
We recommend the HTT5 holdown has a capacity of 4,350 lbs with a 5/8"
diameter anchor bolt. This may be a threaded rod with a double nut and •
washer if it is embedded 4" below the top of the footing.
If you have any questions feel free to give me a call.
