Olshan Foundation Solutions presented the repaired portion of the foundation using 15 exterior and 6 interior steel piles and adjustments beneath the above referenced location for our review. The pile locations and spacing as represented were found to be in general compliance with industry standards, and generally in accordance with Olshan Foundation Solution’s proposal based on the field data provided to us by Olshan Foundation Solutions. In our opinion, the piling depths in conjunction with the pile driving force as reported by Olshan Foundation Solutions are generally appropriate for this type of structure and for the area where the work is being performed. The repair work performed to the subject location is believed to have been acceptably completed, based on the information provided by Olshan Foundation Solutions, in accordance with good industry practice for foundation repair work using steel piles and meets or exceeds the 2021 IRC. The repairs performed on the subject location should be expected to minimize the foundation settlement observed prior to the foundation repair work. In instances where partial repairs are performed, meaning the entire foundation has not been underpinned, potential differential movement may occur. It should be noted that partial repairs modify the design of the foundation and while partial repairs are generally accepted industry practice the possibility of future movement should be recognized. Non-supported areas are not covered for downward foundation movements by the contractor’s warranty. The future performance of the foundation system on the subject location should function as generally intended, provided proper soil moisture is maintained and there is not a loss in the load bearing capacity of the soil beneath the foundation. Soils should be graded such that there is positive drainage away from the foundation or a drainage system can be installed to prevent water from ponding around the foundation. A foundation maintenance program is recommended which can be found at www.foundationperformance.org. We appreciate being of service.
