About this file
This is a Dynamic Pile Testing Report for the NOAA OMAO Ship and Repair Facility project in Newport, Rhode Island. On November 22, 2024, Geosciences Testing and Research, Inc. (GTR) performed high strain dynamic pile testing (HSDPT) on one Open-Ended Steel 30"x0.5" pipe pile designated as Pile 35'B using a BSP CG240 hydraulic hammer with a maximum rated energy of 175.9 kip-ft. The testing was conducted in accordance with ASTM D4945 standards to evaluate pile capacity, driving stresses, and hammer performance. The pile was driven to a final depth of approximately 97.7 feet below falsework, with dynamic testing gages attached at End of Drive (EOD) when the pile achieved 12 blows for 1/2 inch. At EOD, the hammer operated at approximately 4 feet stroke, delivering approximately 92 kip-ft of transferred energy.
The test results indicate that Pile 35'B achieved an EOD Case Method field capacity (RX5) of approximately 1,861 kips and an EOD CAPWAP capacity of 1,815 kips, with approximately 79-80% of total capacity developed in end bearing (1,425 kips) and 21% in shaft resistance (390 kips). Maximum compressive driving stresses of 33.6 ksi at the pile top and 30.2 ksi at the pile tip remained well below the allowable limit of 54 ksi throughout testing, with no pile damage indicated. The design compression load requirement was 800 kips with a required ultimate bearing capacity of 1,800 kips (factor of safety 2.25). GTR recommends that remaining production piles be driven to 20 blows per inch for one inch with the hammer operating at 4.25 feet stroke, corresponding to average transferred energy of approximately 100-120 kip-ft, to achieve consistent performance with the test pile.

Re: Dynamic Pile Testing Report – Pier Bent 35’ NOAA OMAO Ship & Support Facility Relocation
Newport, Rhode Island
Dear John:
At your request, Geosciences Testing and Research, Inc. (GTR) performed dynamic pile testing at the above-referenced site on November 22, 2024. Dynamic testing was performed to evaluate pile capacity, driving stresses, and hammer performance during production pile installation. Dynamic testing was conducted using the Pile Driving AnalyzerTM (PDA) Model 8G, which records, digitizes, and processes the force and acceleration signals for use in the Case Method and CAPWAP analyses. The dynamic testing was carried out in general accordance with ASTM D4945, “Standard Test Method for High Strain Dynamic Testing of Piles” and the Project Specifications.
One (1) Open-Ended Steel 30”x0.5” Pipe pile, designated as Pile 35’B, was dynamically tested during End of Drive (EOD). Refer to Table 1 for further details regarding the dynamic test results, dates of testing and pile designations.
Field Details
Subsurface Conditions
The generalized subsurface profile based on Borings WB-03, WB-02, WB-01 and LB-09 consists of the following stratum from mudline: A weight of rod to a medium dense estuarine deposits extending approximately 20 feet below mudline. Underlying the estuarine deposits is an approximate 20 to 35 thick layer of dense glacial till. Below the glacial till is an approximate 5 to 15 foot thick layer of highly weather bedrock, which extends to bedrock at approximately 35 to 55 feet below the existing mudline. Mudline elevation ranges between approximately -15 to -30 feet. Refer to the Boring Logs prepared by Haley and Aldrich for more information regarding the site specific conditions encountered.
Pile Details
Open-Ended Steel 30”x0.5” Pipe piles were driven for the support of the proposed structure. The cross-sectional area of the pipe section is 46.34 square inches. The required design compression load for the pile is 800 kips. The required ultimate bearing capacity for the pile is 1800 kips based on a factor of safety of 2.25. The maximum allowable compressive and tensile rwhitsel Highlight rwhitsel Highlight rwhitsel Highlight rwhitsel M&N SD Stamp
NOAA OMAO Ship & Support Facility Relocation – Pier PDA Report November 27, 2024 GTR Project No. 24.107 Page 2 driving stress for the piles is 54 kips per square inch (ksi), based on 90% of the yield strength (0.9*Fy) of the minimum yield strength of 60 ksi per the project specifications. Reinforced driving shoes were welded to the tips of the piles.
Driving System Details
A BSP CG240 hydraulic hammer was used to drive the piles. The maximum rated energy for the hammer is 175.9 kip-ft (based on a ram weight of 35.3 kips and a maximum stroke 5.0 feet).
Instrumentation
The instrumentation consists of two strain gages and two accelerometer transducers attached below the tops of the piles. One strain gage and one accelerometer were placed on opposite sides of the pile to minimize the effects of uneven impact and pile bending. This instrumentation provides information about driving stresses (compressive and tensile), hammer performance (transferred energy), and pile bearing capacity.
The PDA is a computer fitted with a data acquisition and signal conditioning system.
During driving, the strain and acceleration signals are recorded and processed for each hammer blow. The strain signal is converted to a force record and the acceleration signal is converted to a velocity record. The PDA saves selected hammer blows containing this information to disk and determines the compressive stresses, displacement, and energy at the point of measurement (pile top). In addition, the pile bearing capacity can be estimated in the field using the Case Method and Energy Approach. This information can be viewed on the computer screen during driving. Selected blows can be further processed to predict the static pile capacity using the CAPWAP analysis. Refer to Appendix A for literature on the dynamic testing, the Case Method, and CAPWAP.
Results
General
The results of the dynamic testing are summarized in Table 1, which includes the driven depth, blow count, stroke, maximum transferred energy, maximum pile top displacement, and maximum compressive stress at the gage location and at the pile tip. GTR observed the blow count and hammer stroke. The PDA at the gauge locations determines the transferred energy, maximum pile top displacement, and maximum pile top compressive stress. The PDA estimates the maximum compressive stress at the pile tip.
Also included in Table 1 is the pile bearing capacity as determined by the Case Method in the field and CAPWAP analysis in the office. Three separate PDA plots of various parameters (maximum transferred energy and displacement - left plot, RMX Case Method capacity with Jc=0.5 and Jc=0.7 - middle plot, and maximum measured compressive stress at the pile top and maximum estimated compressive stress at the pile tip - right plot) are presented for the test pile in Appendix B. Appendix B also contains the above data, and additional data, in tabular form.

In Table 1, the Case Method capacity represents an average over the blows indicated for EOD. CAPWAP analyses were performed on a selected blow from EOD. Appendix C contains the full results of the CAPWAP analysis and Table 2 summarizes the CAPWAP results.
Field Observations and Hammer Performance
Prior to dynamic testing, Pile 35’B was installed with the vibratory and impact hammers to approximately 90 feet below the reference elevation (taken as the falsework). The dynamic testing gages were then attached, and the pile was impact driven to a final depth of approximately 97.7 feet below falsework. At EOD, the pile was driven to 12 blows for 1/2 inch.
The BSP CG240 hydraulic hammer was operated at a stroke of approximately 4 feet, corresponding to an average transferred energy of approximately 92 kip-ft at EOD. Refer to Appendix D for a copy of the draft pile log.
Pile Integrity and Stresses
The field data indicated that the maximum compressive driving stresses were below the allowable limit throughout testing. The pile cap should be positioned directly over the pile axial center of gravity to maintain good hammer alignment during driving. This minimizes bending stresses and keeps local stress concentrations to a minimum.
Pile Bearing Capacity
The EOD Case Method field capacity (RX5) for Pile 35’B was approximately 1861 kips at a driving resistance of 12 blows for 1/2 inch. The corresponding EOD CAPWAP capacity was 1815 kips. Table 2 presents the results of the CAPWAP analysis in more detail. The total capacity, frictional capacity, end-bearing capacity, and percent capacity in the bearing layer are included.
The quake and damping soil parameters as determined from the CAPWAP analysis are also presented in Table 2.
Conclusions
The presented data from the dynamic measurements and their analyses leads to the following findings and conclusions.
1. For Pile 35’B the EOD CAPWAP capacity was 1815 kips. The pile was driven to 12 blows for ½ inch. The hammer was reportedly operated at a stroke of approximately 4 feet, resulting in approximately 92 kip-ft of energy.
2. The EOD CAPWAP analysis indicates that approximately 80% of the pile capacity was developed in end bearing.
3. Pile stresses were below the allowable limit of 54 ksi throughout PDA testing. The dynamic records did not indicate pile damage.
4. Based on dynamic testing to date, we recommend the remaining production piles be driven to 20 bpi for one inch with the hammer operating at a stroke of 4.25 feet, corresponding to an average transferred energy of approximately 100 kip-ft to 120 kip-ft.

Static pile capacity evaluations determined from dynamic testing provide an estimate of the axial pile bearing capacity at the time of testing. At very high blow counts (low pile set), the Case Method and CAPWAP analyses tend to predict lower capacities, since not all of the soil resistance may be fully mobilized, particularly at the pile toe. Other factors not considered in this analysis are bending, down drag, lateral and uplift requirements, cyclic loading, effective stress changes (e.g. due to changes in the water table, excavations, and/or fills), settlement, and pile group effects. The foundation designer should evaluate if any of these issues are applicable to the pile design.
This report has been prepared in accordance with generally accepted geotechnical engineering principles with specific application to this project. Our conclusions are based on applicable standards of practice, including any information reported to and/or prepared for us.

DYNAMIC TESTING LITERATURE

HIGH STRAIN DYNAMIC PILE TESTING
Introduction
Dynamic pile testing (a.k.a. High Strain Dynamic Pile Testing - HSDPT) is commonly employed for evaluating the capacity of driven piles. It is also provides information about hammer performance and pile integrity/stresses. Dynamic testing is carried out in accordance with ASTM D4945, “Standard Test Method for High Strain Dynamic Testing of Piles”. Dynamic pile testing involves using strain gages and accelerometers to record an impact wave and its reflections generated by a piling hammer. Both driven piles and drilled foundations can be tested (provided that an impact hammer is used to create the high strain wave for the drilled foundations).
Procedure
Dynamic pile testing was performed using a Pile Driving Analyzer (PDA®), such as the PAK®, PAL®, or PAX® systems, manufactured by Pile Dynamics, Inc. (PDI) of Cleveland, Ohio. These systems are computers fitted with data acquisition and signal conditioning components. The instrumentation consists of two strain gages and two accelerometer transducers attached a minimum of
1.5 pile diameters below the pile top. During impact, the strain and acceleration signals are recorded and processed for each hammer blow. The strain signal is converted to a force record and the acceleration signal is converted to a velocity record. The PDA® saves selected hammer blows containing this information to disk and determines the transferred energy, compressive/tensile stresses, displacement, pile integrity, and the estimated pile bearing capacity using the Case Method. This information can be viewed on the computer screen during driving. A screen shot of data collection in the PDA® Windows (PDA-W®) Program is provided in Figure 1. Selected blows can be further processed to predict the static pile capacity using signal matching programs.
Figure 1. Data collection during pile driving in the (PDI - PDA®-Win Program).
Theory
When a ram strikes the pile head, it initiates a large strain wave that propagates down the pile as illustrated in Figure 2. External soil resistance or changes in the pile’s impedance (due to variations in the pile’s material or geometry) causes reflection waves that are recorded by the instrumentation.
Knowing the material properties and pile geometry at the point of measurement, the strain can be converted to force, while the acceleration is integrated with time to produce velocity.
Figure 2. Pile instrumentation and hammer impact.
As long as there is no change in the pile impedance and there are no external forces (i.e.
friction), the force and velocity are proportional (equal). Reflections at the tip can be explained by two classical boundary conditions. Free end conditions (analogous to easy driving through soft clay) require zero force and no velocity restrictions at the tip, resulting in a compression wave returning as a tension wave and an increase in velocity (theoretically doubling). Figure 3 graphically presents a typical reflection from a pipe pile during penetration into soft clay. Fixed end conditions (analogous to hard driving into bedrock) require zero velocity and no force restrictions at the tip, resulting in a compression wave being reflected with a greater magnitude than the incident wave (theoretically doubling) and the tip velocity at theoretically zero. Figure 4 graphically presents a typical reflection from an H-pile driven to bedrock. The time the wave takes to travel down to the tip and reflect back to the transducers is twice the pile length divided by the wave speed of the pile material (2L/C).

Figure 4. Typical Force and Velocity traces for an H-pile driven into bedrock (high force and low velocity at tip - 2L/C).
If a pile contains a defect or is damaged (e.g. reduction in impedance) during driving, the wave reflecting from the zone of decreased impedance will show a reduction in the force and increase in the velocity (somewhat comparable to “free end conditions”). These reflections would arrive to the measuring transducers before the expected reflections associated with the pile tip as the damaged zone is at a point along the pile between the transducer location and pile tip. The detection of damage during driving is usually easily identifiable and typically associated with cracking of concrete piles or splice breakage.
Dynamic Testing Summary Output
After data collection, the most pertinent output quantities from the dynamic pile testing can be summarized in a graphical manner. The data can be also presented in tabular format, averaging the results based on penetration depth or blow number as specified by the user. Figure 5 shows typical graphical output. Each of the three plots presents two quantities sharing the vertical (penetration) axis.

Signal Matching Analyses
Signal matching using the dynamic testing data can be performed to predict the static pile capacity. Programs such as CAPWAP® (developed by Pile Dynamics, Inc.) or TEPWAP/PWAP (developed by GTR) are numerical analyses used to solve the one dimensional wave equation using the measured force and velocity. E.A Smith (1960) suggested modeling the hammer-pile-soil system for use in the wave equation by a series of masses, springs and dashpots as shown in Figure 6. The signal matching programs determine the best match between measured and calculated pile top forces and replace the hammer input with the measured force and velocity. The pile is separated into many small segments, often 1 meter in length. The velocity record obtained from the dynamic pile testing transducers is used as input to the top pile segment. The resistance, damping, and quake are the primary soil parameters assigned by the user to each pile segment below grade. The signal matching programs will calculate the displacement, velocity, and stresses (forces) for each pile segment based on the input velocity record and the user assigned soil parameters. These parameters are adjusted and modified in an iterative fashion until the best match is obtained between the force calculated for the pile top segment and the force measured at the pile top during testing. The user assigned soil parameters based on the best match represent the “actual soil conditions”, including the resistance (and therefore pile capacity). This capacity is based on the resistance at the time of the testing. Static load tests are typically conducted several days or weeks after driving. Therefore, restrike tests are recommended to be performed some time after driving to assess time dependent changes in pile capacity, such as setup or relaxation.
