OMNNI Materials Testing

Geotechnical / Materials Testing

OMNNI Associates provides a variety of construction materials testing services that can be tailored to meet the specific needs of your project. Our services provide you with valuable information that identifies problems or potential problems that may jeopardize the quality of the project and cause costly delays. As a member of the design and/or construction team, we strive to provide timely and meaningful information and recommendations to help ensure a quality, cost-effective project.

OMNNI is equipped with its own laboratory that meets the requirements set forth in ASTM:C1077 “Standard Practice for Laboratories Testing Concrete and Concrete Aggregates for use in Construction and Criteria for Laboratory Evaluation” and ASTM:D3666, “Minimum Requirements for Agencies Testing and Inspecting Road and Paving Materials.” We are nationally accredited by the AASHTO Accreditation Program and participate in the AASHTO Proficiency Sample Program for aggregates, concrete and asphalt testing.
