GROUND Engineering currently administers the WAQTC soils program where GROUND assists in the training and qualification of Colorado Department of Transportation and other commerical technicians. GROUND Engineering is the ONLY commercial laboratory in Colorado to provide resilient modulus testing.

Materials Testing

GROUND operates premier, in-house laboratories capable of performing all testing required for your projects. GROUND actively seeks and implements the newest technological methods and equipment to meet the highest industry standards. Our state-of-the-art materials testing capabilities include soils testing, concrete testing, concrete masonry unit (CMU) strength testing, asphalt mix designs and concrete asphalt mix designs. All soil stabilization mix designs are completed by GROUND including fly ash, kiln dust, soil cement, and lime mix designs.

GROUND participates in several national sample programs and is accredited by both the AASHTO Materials Reference Laboratory (AMRL) and the Cement and Concrete Reference Laboratory (CCRL) administered by the National Institute of Standards in Washington, D.C. Our laboratory routinely passes rigorous inspections by the US Army Corps of Engineers and the Colorado Department of Transportation and is currently the back up laboratory facility for the Colorado Department of Transportation.

Resilient Modulus Testing

GROUND's use of resilient modulus testing can save you money on your paving thickness and sub-grade preparation. GROUND is the only commercial laboratory in the State of Colorado that provides resilient modulus testing. All pavement designs are based on the resilient modulus of the supporting subgrade soils. Most pavement engineers obtain the resilient modulus used for design by performing other, less accurate test methods, and use correlations to obtain the resilient modulus. Using a GCTS resilient modulus/Triaxial Testing Machine, GROUND is capable of performing resilient modulus testing for asphalt and soil, including cohesive granular and treated soils.

Internal Quality Control

Our laboratory facility maintains a rigorous quality assurance and check program. This program includes intensive audits by AASHTO Materials Reference Laboratory (AMRL), the Cement and Concrete Reference Laboratory (CCRL), the U.S. Army Corps of Engineers and Colorado Department of Transportation. Laboratory personnel are trained by experienced supervisors and must demonstrate proficiency in testing procedures, instrumentation operation and data reduction. All instrumentation in the laboratory is on a scheduled calibration schedule. Certified professional technicians complete documented calibration of the equipment. Laboratory samples are identified with a unique sample number, which is utilized in tracking the sample through the laboratory and for sample data tracking and archiving.

Mobile Laboratories

Ground Engineering Consultants has the capability of providing our clients with on-site mobile field laboratories. Our eight (8) mobile laboratories give GROUND the ability to respond quickly to any situation which may arise in the day-to-day construction schedule, including testing, curing and sample storage and real time report generation. An on-site laboratory can be utilized to facilitate faster and more cost effective results.
