The inspector observed the installation of (11) FSI 288 push pier, verifying pier locations, installation depth, installation pressure, bracket type, piertype, pier diameter and thickness. To confirm pier capacity, loads were observed following installation and the results were within approved allowances. Please see the attached field installation logs and load test data, dated 9/5/2019. All piers were installed per the intent of the design drawings 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 omission that may arise during and after construction. It is the contractor's responsibility to perform their work in accordance with approved construction documents. All inspections and tests were performed and reported according to the requirements of the City of Edmonds and, to the best of my knowledge, the work was in conformance with the applicable workmanship provisions of the Washington State Building Code and Standards.

Load testing shall be performed in accordance with ASTM Method D1143 (Quick Method). 20 percent of piers shall be tested to 150 percent design load. Load testing creep acceptance criteria shall be no greater than 0.04 inches within a 10 minute period. If movement is observed greater than 0.04 inches within the 10 minute period the load test shall be held for an additional 50 minutes, the pier is to be deepened and re -tested, or the pier is to be abandoned and replace with a new pier. If the load test is to be held the pier movements shall be measure at 15, 20, 30, 40, 50, and 60 minutes. The creep versus the logarithm of time shall be plotted. If the creep rate is less then 0.080 inches between 6 and 60 minutes, the load test shall be considered successful. Non -Compliance Items: Note: Load test performed utilizes a hydralic load cylinder with an effective bore diameter of 3.5" which equates to an operating hydraulic area of 9.62 in2' Pier Test Pressure (psi)=[Design Load] X 1.5 / 9.62in2 Inspectors Signature: F�m
