Your vision for quality becomes reality through accurate assessing, testing, consulting and reporting — our Team of 65 engineers, environmental scientists, geologists, industrial hygienists, inspectors, certified field and lab technicians, and experienced administrative professionals deliver the information you need to make your project a success.

Our diverse client base of local and state government, education, healthcare, financial, commercial, industrial, retail, residential, energy, transportation, churches and religious groups is served from our offices in Oakland, Washtenaw and Wayne Counties.

Over fifty successful years in the engineering profession have encouraged us to share our enthusiasm and expertise with potential engineering students by participating in career programs at numerous school districts and colleges in the Detroit Metropolitan area.
