Dear Building Inspection Division:
This letter serves to certify that in accordance with Chapter 17 of State and International Building Code
requirements outlined in the General Structural Notes on S1.1 of the approved permit drawings, SFA Design

The inspector observed the installation of FSI HP288 Helical Piers, verifying pier locations, installation depth,
installation pressure, bracket type,pier type, pier diameter and thickness. To confirm pier capacity, load tests
were observed following installation and the results were within approved allowances. Please see attached field
installation logs and load test data dated 09/04/18. 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.
