CSD was founded in 1992 by Cindy S. Davis, P.G., a former manager at the Illinois Environmental Protection Agency. Since then, CSD has grown to include personnel from disciplines including civil and environmental engineering and contracting, chemical engineering, mechanical engineering, land surveying, computer-aided drafting, environmental science, cartography, environmental drilling and geology. This combination of education and professional skills allows CSD to offer our clients a network of qualified professionals capable of providing complete services in the areas of engineering and applied sciences. CSD also maintains an outstanding team of research and development experts, for the exploration of alternative remedial technologies.

In 1998, CSD acquired Moss, Johnson & Associates, Ltd., a long-standing civil and environmental engineering firm from the central Illinois area. From its inception in 1972, Moss, Johnson & Associates has strived to unobtrusively integrate civilization with the environment by using a multi-disciplinary approach incorporating economics, sociology, ecology, engineering and construction. This merger allows CSD to provide unsurpassed expertise in the fields of environmental management and land development.

In 2000, CSD formed an independent environmental drilling and contracting company known as Heartland Drilling & Remediation, Inc. (HDR). HDR provides expert, high-quality environmental drilling, sampling, and remediation services throughout Illinois and surrounding states. HDR uses a compact AMS 9600 Power Probe™, mounted on a Case 1845C skid steer. Our rig’s compact design allows nearly limitless accessibility and maneuverability. The equipment we use is ideally suited for environmental applications and can be converted on-site from direct push to hollow-stem augering in less than 60 seconds. The combined ability to provide both probing and augering with a single rig has proven to be extremely valuable and cost-effective for our clients.

 

Since the early 2000's CSD has expanded into civil construction, providing environmental subcontracting services. As the years have passed CSD has expanded into DOT contracting, pre-qualified and certified as a DBE with IDOT, MoDOT, and the City of St. Louis. Our firm has the expertise, personnel and equipment to provide contractors or owners a wide range of construction services including, but not limited to; underground storage tank removal, non-special & special waste removal and disposal, excavation, grading, drainage structures, trucking, demolition, land clearing, erosion control, etc.
