VIOLA ENGINEERING, PC
Serving the Shenandoah Valley since 1996
Construction Materials Testing
VEPC field and special inspection services emphasize personnel qualifications, on the job training and personal accountability to comply with the requirements of ASTM C1077, D3740, E329 and AASHTO R-18. All field technicians undergo a 30-day job training period, of which they are taught basic material sciences, construction techniques, and receive Hazmat training prior to field placement. VEPC remains dedicated to providing clients with qualified field technicians certified by ACI, Internal Code Council (ICC), VDOT, and other agencies to perform construction monitoring and testing services for capital improvement projects as well as private developments.
Geotechnical Engineering
Geotechnical engineering utilizes the disciplines of rock and soil mechanics to investigate subsurface and geologic conditions. VEPC provides drilling services for our clientele to include test borings with Standard Penetration Testing (SPT), rock coring, and percussion hammer drilling to evaluate subsurface conditions, compaction grouting, and alternative foundation systems. VEPC owns drilling rigs, support vehicles, and ancillary equipment to permit immediate scheduling upon request.
Laboratory Services
VEPC has maintained AASHTO Accreditation status at our Harrisonburg laboratory since 2010 and participates in the proficiency sample program, on-site audits, regular equipment calibrations, and continuous quality improvement to ensure consistent and accurate test results. Our laboratory personnel are ready to receive a single sample from a local property owner or process multiple samples to comply with test frequencies for a new landfill cell. Technicians can also be dispatched to sample materials at the source for stockpiles, quarry products, and concrete coring. Professional engineers with in-depth knowledge of the geology of the Shenandoah Valley and surrounding counties are available to interpret and explain laboratory test results.
Geophysical Services
VEPC performs geophysical surveys to assist in evaluating subsurface conditions on geotechnically challenged sites. High electrode count (84) 8-channel resistivity measurement equipment (max ~300-foot imaging depth) coupled with dual frequency precision RTK GPS field location capabilities and GIS special analysis are utilized to obtain detailed subsurface data to gain unique site insights and conclusions. These mapping techniques have been utilized to maximize site designs and minimize karst development costs. In addition, variability in the depth to bedrock can have a major impact on the cost of a project. Mapping the bedrock surface using borings exclusively can be time-consuming and expensive. Combining geophysical test methods with borings can provide superior cost effective data.
