The review included the <br /> Shannon&Wilson pile driving logs and daily inspection reports,along with the PDA and CAPWAP analyses <br /> performed by Rober Miner Dynamic Testing, Inc. This review was performed to verify the assumptions <br /> used in the design and analysis of the wharf upgrades. This review covered three primary pieces of <br /> information, as listed below: <br /> 1. As-driven pile tip elevations <br /> 2. Pile axial geotechnical capacities <br /> 3. Soil-pile axial stiffness <br /> These will be discussed in turn below.There are several referenced documents in this memorandum.They <br /> can be found in the following locations: <br /> • The PDA and CAPWAP analysis results can be found in the contractor Submittals 027 and 028. <br /> • The Shannon and Wilson pile driving logs and inspector daily reports are included as Appendix A <br /> to this memorandum. <br /> • A summary of the pile capacity data and soil-pile axial stiffnesses can be found in a letter from <br /> Shannon&Wilson included as Appendix B to this memorandum. <br /> moffat, &. nichol <br />
