Geotechnical Engineering

Investigation of subsurface soil conditions and evaluation of foundation system and remediation options.

Geotechnical Investigations

Geotechnical investigations typically use test borings to identify the subsurface conditions at the site. Our engineers then evaluate the results of the test borings and prepare a geotechnical report that includes our evaluation and recommendations.

Test Borings

Velocity offers several types of test borings. Standard Penetration Test (SPT) borings are the most commonly used method of investigating subsurface soil and groundwater conditions. SPT borings are performed using a mechanized drill rig which can be mounted on a truck, ATV, tracked carrier, or a barge. If a drill rig is unable to access the site, shallow hand auger borings can be performed using manually operated equipment.

Foundation Analysis

Analysis and evaluation of foundation options for structures including shallow foundations, spread footings, and pile foundation systems.

Ground Improvement Analysis

Analysis and evaluation of the suitability of ground improvement methods including vibro-replacement, dynamic compaction, soil mixing, grouting, surcharging, and demucking.

Settlement Investigations

Investigation into why a structure is experiencing excessive settlement and evaluation of remediation options.

Sinkhole Evaluation

Investigation of the presence of sinkhole activity or cause of an actual sinkhole and evaluation of remediation options.

Geophysical Evaluation

Evaluation of subsurface soil conditions using geophysical methods such as ground penetrating radar (GPR), electric resistivity imaging (ERI), and seismic refraction.

Underpinning & Remediation Design

Designing underpinning and remediation programs for structures that have experienced settlement or sinkhole activity.

Vibration Consulting

Velocity provides consulting services to contractors to help minimize the vibrations caused by construction activities such as pile driving, vibratory compaction, demolition, and blasting.
