Frequently Asked Questions — Prior Lake, MN
Why is there a mobilisation charge on my estimate, and how does my location near Prior Lake, MN affect it?
Mobilisation covers getting the dive crew, barge, air systems, and support equipment to your site and back. It's quoted separately from the daily crew/spread rate, and distance, travel time, and whether the crew has to stage locally in Prior Lake or MN all factor into it. That line often explains why two bids for the same replacement bulkhead differ more than the unit prices.
How far ahead should I schedule bulkhead or pile work in Prior Lake, MN, and who handles the permits?
Scheduling depends on tidal current windows, seasonal weather, and equipment availability; many marine contractors book weeks or months out. Permitting is usually the owner's responsibility, though a contractor should tell you if the work needs state or federal approvals, like a USACE permit, and coordinate with those schedules. Expect the contractor to plan around protected species seasons and in-water work windows set by state agencies.
What kind of report or documentation will I get after an underwater inspection or completed pile repair?
A commercial diving contractor should provide a written report with digital photos, video, and condition notes tied to the structure or substructure unit, plus a summary of findings and recommended repairs. For bridge and some waterfront structures, the report format should follow the inspection requirements (e.g., NBIS for bridges). After construction, you'll get as-built sketches, material certifications, and dive logs; exact deliverables are set in your scope of work.
Can you inspect my dock piles and underwater structure in the water, or do we need to build a cofferdam or dewater the area?
Most routine pile and seawall inspections are done entirely in-water by commercial divers using video and hand-held probing, so no dewatering or cofferdam is needed. If repair involves welding or requires a dry surface to meet the coating spec, then a cofferdam or sheet pile enclosure may be necessary. In-water inspection is generally faster and less disruptive, but dewatering gives you direct visual access and gives the engineer a better look at the worst areas.
