    Underwater Inspection

    ES-Divers is an independent consulting firm not connected to any marine construction entity.  Clients receive objective and accurate reports with precise data to facilitate maintenance and repair.  Waterway support systems—intakes, pipelines, mooring cells, stationary barges, and bridge piers—form the infrastructure of many industries. Flaws, defects, and cracks in these vital components can lead to structural failure and environmental devastation. Regular inspection of these fundamental elements is necessary to protect the life and industry that thrives around them.

    ·         Underwater Bridge Inspection

    ·         Nondestructive Testing & Analysis

    ·         Captioned Photos (Topside and Underwater)

    ·         CAD and GIS Work Products

    ·         Ship & Barge Inspections

    ·         Potable Water / Wastewater Treatment Plants

    ·         Underwater Valve Integrity & Operations

    ·         Underwater Pump & Intake Coating Evaluations

    ·         Sheet Pile Inspection & Repair

    ·         Dolphins & Mooring Cells

    As a division of EnviroScience, Inc., ES-Divers has its roots in environmental / waterway permitting service projects.  Environmental compliance is often a top critical schedule factor in marine construction. Our scientists and biologists are experts at simplifying and expediting agency coordination as well as performing biological surveys, including endangered freshwater mussels, 316(a) and 316(b) studies for federal, state, and local transportation projects, and those associated with NPDES outfall and water intake permit modification, the Federal Transit Administration, and U.S. Army Corps of Engineers (USACE) dredging projects. We work all over the U.S. on environmental compliance support by finding innovative, simple solutions to complex problems. EnviroScience is one of only a few environmental companies that are ADCI Member companies (since 2006) and can meet EM-385-1-1, USCG, USACE and Navy specifications required for Federal projects.
