Geotechnical Engineering Operation
Our team is comprised of geotechnical engineers, laboratory technicians, and scientists. We operate specialized drilling equipment necessary to work in rough terrain, with the ability to drill holes to depths of more than 300 feet and to obtain adequate recovery of samples of rock and soil.
The Iron Mountain, Michigan laboratory has been granted accreditation by the AAP (AASHTO Accreditation Program). Scope of testing can be found on the AAP Directory of Accredited Laboratories.

Our regional locations allow us to provide testing services for the Michigan Department of Transportation (MDOT), Wisconsin Department of Transportation (WisDOT), Federal Aviation Administration (FAA) and private sector clients throughout the Great Lakes Region.
Technicians are trained and certified in the most current standards and testing procedures. They are also certified by MDOT and WisDOT as aggregate, concrete and bituminous inspectors. Our team has vast experience with projects designed and constructed using MDOT, WisDOT and FAA specifications. Coleman Engineering Company is also certified to conduct annual inspections and certifications of concrete redi-mix plants in accordance with the National Redi-Mix Concrete Association (NRMCA) standards.

Pressure Meter Testing
The Pressure Meter Testing (PMT) is an in-situ test method used to evaluate soil strength in place. This allows engineers to design foundations using actual in-situ soil parameters instead of conservative values based on soil type.
Parallel Seismic Survey
The Parallel Seismic Survey is used for determining the depth of vertical subsurface structures such as well pipes, drill casing, foundations, piles, and sheet pile of varying material types.
Soil Resitivity
Collaborating with the electrical industry, we have developed efficient and economical procedures for performing field soil resitivity and testing ground grid. Results are used for the design and confirmation of electrical ground grid systems.
Vane Shear Testing
The vane shear apparatus consists of a four-blade stainless steel vane attached to a steel rod that is pushed into the ground. The vane shear test is used for measuring the undrained shear strength of cohesive soil.
