Dear Building Inspection Division:
This letter serves to certify that in accordance with Chapter 17 of the International Building Code requirements
outlined in the General Structural Notes on S 1.1 of the approved permit drawings, SFA Design Group, LLC has
performed special inspection as detailed below.
The inspector observed the installation of (7) FSI HA150 helical tieback, verifying pier locations, installation
depth, installation pressure, pier type, pier diameter and thickness. Please see attached field installation logs
dated, 01/28/2019 and 01/29/2019. All anchors were installed per the intent of the design and any installation
deviations were reviewed and approved by this office with no outstanding non-compliance items.
Our inspection and testing services do not constitute a warranty or guarantee of any type and were provided and
intended to help reduce the risk of construction defects, deficiencies or omissions that may arise during and after
construction. It is the contractor's responsibility to perform their work in accordance with the approved
construction documents. All inspections and tests were performed and reported according to the requirements of
the City Building Regulations and these Administrative Rules and, to the best of my knowledge, the work was in
conformance with the applicable workmanship provisions of the State Building Code and Standards.
Sincerely,
Dustin Huddleston
Engineer Technician — SFA Design Group
