Frequently Asked Questions — Baltimore, MD
Can an underwater survey be done while the vessel or structure remains in the water, or is a haul-out required?
For many condition and damage surveys, in-water work by commercial divers avoids dry-docking costs, but it doesn't replace out-of-water inspection of hull plating above the waterline or internal structure. The surveyor decides if in-water coverage meets the requested scope, and some insurance or regulatory conditions may still require a haul-out for through-hull or shaft seal verification. In Baltimore, MD, the choice often comes down to water visibility, current, and the specific items covered by the survey.
How is commercial diving survey work priced, and why would two bids be very different?
Survey work using commercial divers is normally quoted as a crew/spread day rate plus a separate mobilisation charge to get equipment and personnel to the site. Inspection work is often priced per structure or per substructure unit — per pile, per tank, per hull — while repair or marine construction is unit-priced by the linear foot or per pile. Mobilisation is the line item that most often explains a large gap between two quotes, because it includes travel, dive system setup, standby diver, and supervision, and can vary with site access and conditions in Baltimore, MD. Don't compare day rates alone; ask for line items showing dive team, plant, and mobilisation.
Who will actually be in the water, and what diver credentials should I expect?
Commercial diving operations in the U.S. are regulated by OSHA 29 CFR 1910 Subpart T and require a dive team — including a designated person-in-charge, line tender, and standby diver — not a single person. Look for commercial divers trained through an accredited commercial diving school and, for bridge or infrastructure work, an FHWA-NHI qualified team leader if the structure falls under NBIS. Recreational diver certificates such as PADI or NAUI are not commercial diving qualifications and do not meet OSHA requirements. Ask the contractor to provide OSHA Subpart T compliance documentation and ADCI consensus standard accreditation for the dive supervisor.
What should the survey report contain, and what turnaround or scheduling should I expect?
A condition or damage survey report should include the date, location, water conditions, scope limitations, a description of each examined element, photographs or video logs, measurements, and a clear opinion on cause or condition. Reports generally also note applicable standards referenced, such as AWWA M42 for potable water tank inspection, NBIS for underwater bridge inspection, or 46 CFR 71.50-3 for UWILD hull exams. Delivery time is usually agreed in your survey contract and depends on site access, permits from the U.S. Army Corps of Engineers or state agencies, and the level of detail needed; ask about schedule before authorising work.
