Would you like help managing your compliance requirements?
In order to help monitor and manage water quality and compliance related to the construction of BC Hydro’s 3,609-foot (1,100-metre) wide hydroelectric dam across the Peace River, we employed our EcoDAT data management system to efficiently automate and centralize project data acquisition, analysis, and compliance reporting.

Do you want your next big capital project to be a success?
By analyzing and testing a wide variety of scenarios, we helped conduct L4 and IST (L5) testing to identify and recommend corrections for nearly 200 design and construction issues, helping to ensure reliability and performance of the facility.

Do you need expert guidance to ensure your environment is safe?
To ensure the safety of a transdermal patch, we partnered with our pharma client to perform extractables and leachables (E&L) testing and toxicological assessment of the results to assess the product’s safety and quality which enabled the company to efficiently meet deadlines, established safety of the new formulation, and facilitated a smooth review by the FDA.

Are you interested in managing compliance cost efficiently?
As Frazier looked to expand plant operations, our team was brought in to manage the environmental compliance duties at five plants and assist in permitting for new facilities as well as existing facility updates. The result was reduced cost and effort in the reporting process, and new confidence in planning future expansions.
