Frequently Asked Questions — Bronx, NY
Why are dredging quotes structured as a day rate plus mobilisation, and what does mobilisation cover?
Commercial dredging is usually priced as a crew and equipment 'spread' day rate for the time on site, plus a separate mobilisation charge to move the dredge, barges, and support vessels to Bronx, NY and set them up. Mobilisation often explains why two bids for the same volume differ, because a small project still pays for the same long-distance move. Ask for a breakdown of both lines and any standby time terms.
What permitting and scheduling issues can delay a dredging project in Bronx, NY?
Dredging typically requires a USACE permit under Section 404, and NY may have its own environmental or coastal permits. Work is often restricted by fish spawning windows, eelgrass or shellfish seasons, and turbidity limits. You should confirm who is responsible for permits and how long they typically take before expecting a start date.
What reporting and as-built information do we get after dredging?
A professional dredging contractor will provide a pre-dredge hydrographic survey, daily production logs, and a post-dredge survey showing achieved depths and volumes. You should request the survey data in both PDF and raw format (such as XYZ or GeoTIFF) for use in your own GIS or by your engineer. If any areas are left shallow, the report should clearly flag them.
Can you dredge our marina without hauling out all boats or closing the basin?
Most hydraulic dredging is done in-water with a diver or remotely operated dredge, and silt curtains or turbidity screens keep sediment from spreading. The trade-off is that in-water work may need to pause when boats transit near the dredge head, and some confined basins require partial dewatering or a temporary sheet pile closure for mechanical work. Haul-out or dewatering is more disruptive but can make sediment removal faster and easier to verify.
