Cross-hole sonic logging was performed to investigate the extend of the anomalies that were found in GGL or to investigate the obstructions that prevented GGL.

Provided gamma-gamma logging for Cast-In Drilled Hole (CIDH) piles with nominal diameters between 48 inches and 72 inches for Antelope Wash Bridge and Moss Wash Bridge that were constructed as part of Kingman-Wichenburg Highway (US93) Project in Mohave County, Arizona to test the integrity of the shafts. Cross-hole sonic logging (CSL) was performed to investigate the extend of the anomalies that were identified in GGL.

Provided gamma-gamma logging (GGL) for 2 Cast-In Drilled Hole (CIDH) piles with nominal diameter of 144 inches and approximately between 40 and 80 feet-deep to test the structural integrity of the piles. Cross-hole sonic logging (CSL) was performed to investigate the extend of the anomalies that were found in GGL.

Provide gamma-gamma logging (GGL) for 10 Cast-In Drilled Hole (CIDH) piles with nominal diameters of 60 through 108 inches and approximately between 100 and 150 feet-deep to test the structural integrity of the piles. Anomalies that were found in GGL were then confirmed using cross-hole ultrasonic logging (CSL).

Provided Pile Dynamic Analyzer (PDA) monitoring and interpretation for the piles driven at Pier E. Approximately 925 112-foot and 116-foot-long, 24-inch octagonal prestressed concrete piles were driven from a barge using ICE 1514 hammer and from land using Delmag 80 hammer. Recommendations were given regarding bearing capacity at the end of driving and upon retap and regarding integrity of the pile. 

Provided pile driveability study (Wave Equation Analysis), Pile Dynamic Analyzer (PDA) monitoring, CAPWAP Analyses and interpretation for the piles driven at Junction Wash Bridge. Steel H piles with a nominal width of 14-inches, a lineal weight of 89 pounds (HP14X89) and a total length of approximately 30 feet (ft) were driven using a PILECO D36-32 single acting open-ended diesel hammer. Recommendations were given regarding bearing capacity at the end of driving and upon restrike and regarding integrity of the pile.  

Provided Pile Dynamic Analyzer (PDA) monitoring and interpretation for the piles driven at San Elijo Lagoon Double Track Project in San Diego, California. Approximately 60-90 ft long steel pipe piles with a nominal diameter of 24 and 36 inches with a wall thickness of 1 and 1.25 inch, respectively were driven from using a PILECO D62-22 diesel impact hammer. CAPWAP Analyses were performed and recommendations were given regarding bearing capacity at the end of driving and upon restrike.

Provided Pile Dynamic Analyzer (PDA) monitoring and interpretation for the piles driven. 35 feet-long, 14-inch square prestressed concrete piles were driven from using Delmag 30-42 Hammer. Recommendations were given regarding bearing capacity at the end of driving and upon retap. 

Provided Pile Dynamic Analyzer (PDA) monitoring and interpretation for the piles driven. 90 feet-long, 16.5-inch square prestressed concrete piles were driven from using BRUCE 1415 hammer. Recommendations were given regarding bearing capacity at the end of driving and upon restrike.

Provided pile driveability study (Wave Equation Analysis), Pile Dynamic Analyzer (PDA) monitoring, CAPWAP Analyses and interpretation for the piles driven at Junction Wash Bridge. Steel pipe piles with a nominal diameter of 18 inches with a wall thickness of 0.75 inches were driven using a PILECO D46 single acting open-ended diesel hammer. Recommendations were given regarding bearing capacity at the end of driving and upon restrike and regarding integrity of the pile.  

Provided analysis and monitoring of vibrations resulting from pile driving operation on adjacent properties as well as existing abutments. Pile driving activities were done in multiple sections along Interstate 5 freeway in Greater Los Angeles area  (such as Glendale, Burbank, Santa Fe Spring, Norwalk), California. Vibration levels and frequencies were monitored to confirm that they remained within acceptable levels in accordance with project specifications. 

Provided analysis and monitoring of vibrations resulting from driving of steel and concrete piles for various bridges driven within 25’ of Metropolitan Water District (MWD) concrete encased 96-inch pipeline (Sepulveda Feeder) passing along the Sepulveda Boulevard. Vibration levels and frequencies were monitored on top of the pipe and at the ground surface during pile driving to confirm that vibrations remained below acceptable levels, as indicated by the preliminary analysis and indicator program. 

Provided integrity testing of for approximately 120 Continuous Flight Auger (CFA) piles with a nominal diameter of 16 inches for proposed Xebec Distribution Buildings in Sun Valley, California. Piles were tested and analysed to test the integrity using Sonic Echo (SE) and Impulse Response (IR).

Provided SPT hammer energy measurements during Mud-Rotary drilling at multiple boring locations. SPT energy measurements were performed by placing a 2ft instrument section of drill rod on top of the drill string between hammer and existing sampling rods. Acquired measurements were then analyzed and recommendations were given.

Provided analysis and monitoring of vibrations resulting from vibrating thirty nine AZ17 Sheet piling pairs installed adjacent to Irvine Ranch Water Districts (IRWD) 48” water pipe which runs 12’ below grade in Sand Canyon Avenue. Vibration levels and frequencies were monitored on top of the pipe and at the ground surface during pile driving to confirm that vibrations remained below acceptable levels, as indicated by the preliminary analysis and indicator program. 

Provided analysis and monitoring of vibrations resulting from the pile driving activities at Abutment 1 of bridge 55-1103E on the property located at 12836 Bailey Street, Garden Grove, California to confirm that vibrations remained within acceptable levels.
