In late 2007, Cobb’s Construction Management Division added a materials testing laboratory to support its inspection services. Services provided include laboratory testing of soils, aggregates, and concrete test specimen. Additionally, field services include sampling and testing of fresh concrete, making and curing concrete cylinders, and in-place nuclear density testing.
In 2009, the lab expanded services to included soils analyses for foundation designs and field testing for commercial clients.
CEC technicians are equipped with all of the sampling, concrete testing and miscellaneous equipment necessary to perform their jobs. They are all ODOT-certified for sampling and testing. Our testing lab in our Oklahoma City Office allows us to maintain accurate and timely materials test results, which are critical in project management.
