Frequently Asked Questions — Lafayette, LA

How is commercial diving work priced for inspection and marine construction?

Pricing is typically a crew/spread day rate plus a separate mobilisation charge. Inspection is often quoted per structure or per substructure unit, while marine construction is usually unit-priced per linear foot or per pile. The mobilisation line is the most frequent reason for a large gap between two bids, so compare that carefully.

What does mobilisation cover and how does it affect service area in Lafayette, LA?

Mobilisation covers getting the dive team, equipment, and support vessel or spread to your site in Lafayette, LA, including travel time, logistics, and setup. It's standard to quote this separately, and it can vary widely depending on water depth, site access, and distance from the contractor's base. Always request a mobilisation breakdown to understand what you're paying for.

What reports and deliverables can I expect after a subsea inspection?

You typically receive a written report with video, photos, measurements, and findings. For bridge work, the inspection must be led by an FHWA-NHI qualified team leader to satisfy 23 CFR 650.311 / NBIS. For UWILD, the report supports the 46 CFR 71.50-3 in-water hull exam. Confirm the reporting format before award so it aligns with your regulatory or class requirements.

When should I choose an in-water dive inspection over hauling the asset out?

In-water inspection is often faster and less expensive because it avoids dry-dock costs and downtime, but it can be limited by water clarity and weather. For water tanks, AWWA M42 and AWWA C652 address inspection and disinfection of in-service facilities. For hulls, an in-water exam under 46 CFR 71.50-3 may be allowed, but a haul-out gives a more complete picture of the bottom. The right choice depends on your schedule, operational constraints, and whether the asset can be taken out of service safely.
