Subject: Special Inspection of Epoxy Holdown Anchors
19737 Amherst Drive
Cupertino, California
Gentlemen:
This is to certify that special inspection was performed for the installation of six (6)- 5/8"
diameter all -thread rods imbedded through plywood shear walls into existing concrete
foundation. /
The installation of 5/8" diameter rods were drilled with 3/4" diameter holes, 12" deep.
The holes were wire brushed and cleaned. They were then filled with high strength
Simpson SET -XP adhesives. The all—thread rods were then inserted into the holes. The
contractor was informed on site that a dry time of 24 hours shall be allowed before the
hold-downs are attached to the walls and the rods shall not be loaded within 72 hours
after installation.
Based upon my observations and to the best of my knowledge, the installation satisfies
the procedures recommended in ICC report ESR -2508. This letter shall be used solely as
special inspection report of the installation of epoxy holdown anchors, and the contractor
is not relieved from compliance with the structural documents. This letter shall not be
used as approval for any construction operations/practices iri the field.
Very Truly Yours,
Frank L. Kong, P.E
