NEW JERSEY TRANSIT
Level 2 Underwater Inspection
Coastal Engineering regularly performs Type-2 underwater structural inspections on bridges and culverts of all sizes and types. All include fathometric surveys, digital photographs, detailed condition tables, and reports with drawings that adhere to NJTA and DOT standards. Per these standards, our inspections include a 100% level I “swim-by” overview; a 10% Level II detailed inspection of the substructure elements with cleaning of marine growth and measurement of damaged/deteriorated areas; and inspection and probing of the channel bottom and adjacent areas for scour and deterioration.
Coastal works with stakeholders to determine any unique challenges before performing these inspections. We use Commercial Surface Supplied Air and/or Commercial Air SCUBA diving methods to complete the work effectively and efficiently. Work is performed in accordance with FHWA, AASHTO, OSHA, NJDOT, and ADCI standards.
