Rii’s Environmental Services Division possesses a high level of knowledge and expertise for solving difficult environmental issues by addressing health and safety concerns and all regulatory requirements.

Our environmental staff includes Certified Professional Geologists, Certified Asbestos Inspectors and Abatement Designers, Certified UST Inspectors, as well as Professional Engineers who provide environmental services on both large and small projects to national engineering companies, architects, transportation agencies, government agencies, airport authorities, parks and recreation departments, and more.

In addition, we can develop the specifications for bidding and provide abatement oversight. For new site development, we are well versed in performing environmental site assessments (ESAs), as well as providing wetland delineations, EPA and USACE permitting, and UST investigations and services.
