We offer environmental consulting expertise to commercial, industrial, and other regulated communities, primarily to help clients understand and manage risk. Goals typically include providing environmental due diligence prior to property transfers, evaluation of potential contaminants and pertinent regulations and regulatory compliance, and site investigation and remediation. We develop cost-effective site investigations that stay focused on the end goal of final site remediation and regulatory agency approval, so sites can be returned to productive use. The standards and approaches we follow also provide support and documentation for potential environmental litigation, regulatory actions, and property transfers.

We regularly follow up our design phase services by providing construction support. All of our personnel are well versed in the value geotechnical and environmental oversight contribute to successful project completion. Our staff members provide effective observation and testing services as well as comprehensive documentation. We also have SCS certification and can help contractors meet SCS goals on large public works projects.
