CME provides complete inspection services ranging from complete quality control programs to quality assurance audits to spot inspections. Our field personnel are NAQTC, ACI, CALTRANS, ICC, AWS and ANSI qualified to perform all levels of construction inspection. Many of CME’s field personnel are trained to perform both inspection and testing. This approach allows on-site inspectors to conduct sampling and testing, which can eliminate the expense of an added technician to conduct materials testing and provide cost-efficient services to our clients.
Examples of specific inspection services we provide include:
• Soils quality control services from laboratory material qualification testing to field placement and compaction.
• Asphalt quality control services from materials qualification testing and structural section design to field placement testing to rehabilitation. Slurry Seal and Microsurfacing inspection and testing programs have included calibration of placement equipment, verification of slurry mix designs, testing of aggregates, and quantifying placement volumes.
• Concrete quality control services from testing of raw materials for potential use in concrete to field placement testing to testing of hardened concrete. Specialized concrete inspection equipment includes FACE dipstick floor profiler, MIT dowel bar scanner, and concrete maturity meters to name a few.
• Roadway inspection services for new construction, rehabilitation, reconstruction, and roadbed modification projects; inspecting placement of materials such as Portland cement concrete (PCC) pavements, asphalt concrete pavements, tack coat, prime coat, aggregate bases, treated bases, subbases, borrow material, and subgrade.
• IBC chapter 17 Special Inspection programs including structural concrete, prestressed concrete, reinforcing steel, structural welding, high strength bolting, structural masonry, spray-applied fireproofing, and soils.
CME prides itself in its ability to respond quickly to testing requests in the field. Often available for same-day testing and/or inspection, our field personnel are regionally and nationally certified to conduct testing for a variety of construction projects. On-site testing abilities include soils, concrete, asphalt, aggregates, structural masonry, spray fireproofing, structural steel, and high strength bolting. Our four mobile testing laboratories for soils, concrete, and asphalt can also be utilized, with the capabilities to be set up with water and electricity for use on remote sites where transportation to and from may be difficult to achieve in a cost-effective manner.
In addition to testing capabilities in the field and mobile laboratories, CME maintains one of the largest materials testing laboratories in the region, providing testing to both private clients and public works agencies with the capability to perform testing that includes:

Our geotechnical investigation program involves four distinct phases: Field Investigation, Laboratory Testing, Analysis, and Report Preparation.
PHASE 1 – Field Investigation involving geologic mapping, drilling and/or excavating, sampling, logging, and monitoring services to provide a complete geotechnical characterization of the site for both the design and construction phases of the project. Materials can be tested in-situ to characterize their strength properties when required. Our four Senior Geologists average 29 years of field experience and offer detailed analysis of field geologic conditions.
PHASE 2 – Laboratory Testing in our AASHTO and CCRL accredited laboratory. Our four Senior Materials Technicians total 70 years of geotechnical laboratory testing.
PHASE 3 – Analysis, which compiles the data from the field and laboratory phases to develop comprehensive geotechnical recommendations for the project. The CME Geotechnical Group utilizes state-of-the-art software and analytical methods to provide design recommendations.
PHASE 4 – Report Preparation. CME prides itself in providing a concise yet comprehensive report detailed recommendations.
The technical professionals of CME are leaders in materials engineering, specializing in concrete mix designs, asphalt mix designs, and manufactured aggregates. Our staff of experts can assist with materials consultation and engineering services on a host of projects including highways, airports, buildings, parking garages, industrial developments, power plants, military installations, dams, and pipelines.
Our materials engineers and geologists have assisted aggregate producers in pit development and product suitability studies for ready-mix concrete, asphaltic concrete, aggregate base, slurry seals, cement-treated bases, asphalt permeable base, open-graded asphalt, and backfill materials.
Concrete Mix Designs – CME provides concrete mix designs to all major ready-mix concrete suppliers in the region. With decades of design experience, our engineers have compiled a library of designs including thousands of mix combinations utilizing numerous recognized aggregate sources and leading chemical admixtures. Our concrete designs have been used on a wide array of projects including buildings, roadways, airport runways, bridges, and miscellaneous post-tensioned structures. We regularly consult with contractors on the best selection of concrete materials to meet the requirements for groups such as the Nevada Department of Transportation, Caltrans, Federal Aviation Administration, International Building Code, Bureau of Reclamation, Bureau of Indian Affairs, Nevada Public Works Board, California Department of the State Architect, U.S. Navy, and the U.S. Army Corps of Engineers.
