Responsive field services and geotechnical input during construction helps contractors adapt to changing site conditions, confirm subsurface performance, and meet project requirements.
A clear understanding of subsurface conditions and regional geology helps contractors anticipate challenges and prepare more competitive bids. By drawing on our institutional knowledge of this region, we help project teams build a “better mousetrap,” a smarter in-house approach that reduces risk, improves planning, and supports successful delivery. This support includes bid time Engineer help, evaluation of value engineer deep foundation attention, specialty deep foundation testing such as High-Strain Dynamic Testing, commonly referred to as Pile Driving Analyzer (PDA) Testing (ASTM D4945) , Low-Strain Integrity Testing, commonly referred to as Pile Integrity Testing (PIT) (ASTM D5882) , Thermal Integrity Profiling (TIP) (ASTM D7949), and Crosshole Sonic Logging (CSL) (ASTM D6760).
Our team can also provide excavation support design, geotechnical and structural instrumentation, vibration monitoring, and real-time decision-making, providing you with the data and guidance you need to stay on schedule and maintain quality.
Core Services
- Value Engineering of Deep Foundations and Retaining Structures
Develop alternative deep foundation and wall designs to reduce cost, simplify construction, or better suit site conditions. - Temporary Excavation Support Design
Provide practical shoring system designs, including bracing, tiebacks, and soldier piles, to promote safe staged excavation. - Pile Driving Observation and Load Test Coordination
Observe pile installation, confirm driving criteria, and coordinate load tests to verify capacity and support QA/QC requirements. - Site Geotechnical Instrumentation Setup and Monitoring During Construction
Install and monitor inclinometers, piezometers, settlement plates, and other instruments to track performance and protect adjacent structures. - High-Strain Dynamic Load Testing ASTM D4945 (PDA with CAPWAP)
Use dynamic pile testing to confirm axial capacity, evaluate driving stresses, and meet design and code requirements. - Thermal Integrity Profiling ASTM D7949 (TIP)
Assess the shape, size, and uniformity of drilled shafts using heat signature data collected during concrete curing. - Low-Strain Integrity Testing ASTM D5882 (PIT/Sonic Echo)
Perform non-destructive testing of cast-in-place or precast piles to detect potential defects or changes in shaft continuity. - Crosshole Sonic Logging ASTM D6760 (CSL)
Test drilled shafts for internal anomalies such as voids or necking using sonic wave travel between access tubes. - Vibration Monitoring
Real-time monitoring for construction activities such as pile driving, excavation, or demolition. Includes threshold alerts, daily reporting, and underwater vibration services for marine construction. - Length Inclusive Test Equipment (LITE)
The LITE tool allows determination of the length of existing foundation elements with high steel composition, such as driven HP and pipe piles, steel cased shafts, and heavily reinforced drilled shafts. - SPT Hammer Calibration ASTM D4633
This test calibration SPT soil sampling hammers by measuring the energy transfer using dynamic methods. This test helps normalize the raw SPT – N value and standard energy level.
