Dear Mr. Schwaller,
P&r,t4 rr 8G2E -o?-fig - 538 I
I have performed Quality Assurance Inspection for the High Strength Bolts on Mr. Paulson's
garage in accordance with the 2015 International Building Code and the ANSI/AISC
Specification for Structural Steel Buildings. The high strength bolted connections are
acceptable.
On November 14, 2018 I visited the site of the garage construction for Mr. Paulson to perform
special inspection of the high strength bolts. The plans for the garage by Armstrong Steel, Job
No. 55733 were referenced and indicate that all high strength bolts are A325 -N bolts designed
as bearing type connections, unless noted otherwise. The plans and details do not indicate that
pretensioning of the bolted connections is required. Based on this, the bolted connections were
observed to verify that the proper fasteners were installed and a representative number of bolts
were tested to verify that they were installed to a snug tight condition.
If there are any questions or clarifications needed, please feel free to contact me.
Sincerely,
John E. Partch, P.E,
Senior Engineer
