Our laboratory is AASHTO Accredited and Army Corps of Engineers certified with a staff of laboratory technicians that are certified by the American Concrete Institution (ACI), Virginia Department of Transportation (VDOT) and Troxler School to perform the full range of laboratory and field tests. All technician personnel work under the direct supervision of our professional staff to ensure the quality of our services.
Our fully equipped laboratory is located at our central office. Completely remodeled and expanded in 2008, our facility is quickly becoming a prominent fixture in our local area. At present, our laboratory occupies over 3,000 square feet of our facility. Our facility has been painstakingly outfitted with a wide variety of the most technologically advanced equipment available.
Our local laboratory facility is inspected periodically by AASHTO and accredited by AASHTO, Cement Concrete Reference Laboratory (CCRL), and the Army Corps of Engineers. Each year our laboratory equipment is calibrated by Omega Balance Company and Professional Calibration, Inc. In addition, our firm participates in reference laboratory programs hosted by CCRL and AASHTO. Our facility is also certified by VDOT to perform asphalt design and testing and meets the requirements of ASTM C 1077, ASTM D 3666, ASTM D 3740, ASTM A 880, ASTM E 543 and ASTM E 329.
Our laboratory is staffed with individuals having a combined fifty years of experience. Our technicians are periodically enrolled in training and refresher courses provided by American Concrete Institution (ACI), ICC, VDOT, NICET, Troxler, Virginia Asphalt Institute Association, and Geophysical Training Consultants. All professional reports are prepared under the direct supervision of a Licensed Professional Geologist or Professional Engineer. All laboratory and field test work is reviewed by these registered individuals to confirm data is being developed in accordance with established standards.
