Attachment A Financial Project ID (s): 436379-2-54-01 applicable) and the results of the rock coring performed (coring time, recovery and RQD). • Analyze the load test data, pilot holes and any other available soils/rock data as required to establish final drilled shaft tip elevations and minimum rock socket lengths. Submit report(s) recommending production shaft tip elevations, minimum rock socket lengths and any other recommendations that may be required in the project (such as rock socket material definition and impact of permanent or temporary casing on the required minimum socket lengths) to the DGE for approval. • Inspect the bottom of the shafts for cleanliness using manual soundings or shaft inspection device as required in the contract documents. • Complete all necessary drilled shaft inspection forms and keep a log of all inspections made of the shafts. Observe the performance of any load tests and verify that the details are implemented as planned. • Provide completed drilled shaft inspection forms for all production and test shaft installations to the DGE upon completion of the drilled shaft installation. • When conditions occur, which are different from those indicated on the plans, immediately report them to the Geotechnical Engineer of Record and the DGE. Recommend adjustments to the authorized depths as necessary to obtain the shaft capacity to the DGE for approval. • Review the drilled shaft logs and the concrete placement logs to identify possible shaft integrity problems and potential causes. Communicate identified issues to the DGE. • Hire a Specialty Engineer to perform non-destructive integrity testing of drilled shafts as required to estimate shaft uniformity and to detect possible shaft defects. Report results to the DGE. • Evaluate problems encountered during construction, and coordinate with the DGE and the Contractor to resolve such problems, including possible withdrawing Drilled Shaft Installation Plan approval. 2) Piles: (N/A) • Process and review the Pile Installation Plan in accordance with CPAM. • Perform preliminary Wave Equation Analyses to assess and provide comments regarding the suitability of hammer driving system(s) included in the Pile Installation Plan. Provide analyses results (estimated blow count ranges for the nominal bearing resistances, installation stresses etc.) to the DGE. • Schedule a pre -pile installation meeting to review and discuss the pile installation procedures. Make sure the Contractor's field superintendent, CEI's pile inspectors, and the DGE are invited. Prepare and distribute meeting minutes to the attendees. • Provide personnel proficient in operation of the PDA or EDC monitoring equipment required for the project, for data collection, interpretation and analysis. Utilize the most current version of equipment and software for dynamic testing and dynamic data analysis. • Perform dynamic testing per the contract documents during initial driving and re - drives. Submit electronic Pile Driving Analyzer (PDA) and Embedded Data Collector (EDC) files upon completion of the test pile installation. • Inspect and record the test pile driving process in accordance with CPAM.
