Construction Materials Engineering Testing

D&S Engineering takes pride in being a part of the team from the beginning of project design through construction. We work with our clients to ensure the proper design criteria are established, quality materials are selected, and construction is provided according to plans and specifications. Our NICET, ODOT, and ACI certified field technicians provide reliable testing services for a comprehensive range of construction materials. Expect to receive rapid, accurate results for both field inspection and laboratory analysis.

Our laboratories have been inspected by the Texas Department of Transportation (TXDOT) and approved for TXDOT projects. Equipment has been calibrated to the National Institute of Standards of Technology (NIST). All laboratories participate in the Cement and Concrete Reference Laboratory (CCRL) and ASSHTO Materials Reference Laboratory (AMRL) proficiency sample program.  The Ardmore laboratory participates in CCRL, AMRL, and Oklahoma Materials Reference Laboratory (OMRL) proficiency sample programs and is an Oklahoma Department of Transportation approved laboratory for material testing.
