Engineering Services

EA manages every detail of construction.  From the constructability review to final closeout, EA works diligently to promote constructability throughout the process, minimize change orders, and avoid delays.  Onsite, EA monitors construction activities to ensure compliance with plans and specifications and promote workplace safety.

Through the integration of engineering, science, and technology, we offer our clients sound solutions to ecosystem restoration—from ecosystem evaluation and site selection through field investigations, project design, permitting, and monitoring.  Our clients rely on us to restore estuaries and salt marshes, create wetlands, remove dams, beneficially re-use dredged material, restore contaminated sites, and enhance fish passages…and we often succeed with award-winning results.
