Project Name: Maunalua Bay Boat Ramp Dredging
Location: Oahu
Year: 2026
AMC was hired by the State of Hawaii to perform maintenance dredging at Maunalua Bay. Dredge material offshore was used as backfill to compact and level the upland facility which had eroded over the years. High quality dredge sand was capped on the local beach for a great improvement in the beach quality. The seawall on both ends of the Boat Ramp was upgraded with a newly driven sheet pile wall with a concrete cap for a stronger and longer lasting wall to protect further coastal erosion and aesthetic improvement to the park.
AMC is happy to announce the successful completion of this critical local community project ahead of schedule.
Project Name: Mala Wharf Boat Ramp Maintenance Dredging
Location: Lahaina, Maui
Year: 2025
AMC was hired by the State of Hawaii to perform maintenance dredging at Mala Wharf Boat Ramp. AMC has performed this operation multiple times in our History and from this many years of experience we have developed the most efficient and safest methodology to dredge this remote area on the Island of Maui. The project consisted of building a land-side containment berm to hold the dredge spoils until the moisture content was reduced to sufficient levels for disposal. AMC mobilized our spud barge with dredging excavator and tug boats to efficiently dredge the project site. During the project our Team successfully handled the project’s small footprint that restricted barge maneuvering and require in depth local knowledge of the Harbor. AMC was able to finish the project on time and budget and keep the critical boat ramp open to the residential and commercial operators during the entire project.
Project Name: Wailoa SBH Maintenance Dredging
Location: Hilo, Hawaii
Year: 2024
AMC was hired by the State of Hawaii to construct a new concrete abutment and aluminum framed loading dock with plastic lumber fenders and fiber reinforced plastic decking at Keehi Small Boat Harbor, Honolulu, Oahu. Existing piles needed to be repaired via cleaning and underwater concrete for pile foundation and pile encasement. Pile caps were poured to support the new aluminum dock installed.

Project Name: Wailoa SBH Maintenance Dredging
Location: Hilo, Hawaii
Year: 2024
AMC was hired by the State of Hawaii to provide emergency dredging at Wailoa River Basin in the Fall of 2024. The water depth had filled into dangerously shallow levels that created a hazards for the critical fishing and local boating community. AMC mobilized our spud barge with dredging excavator efficiently and quickly to remedy this critical situation.
The project was a success finishing on time with roughly 23,000CY of material dredged and deepening the channel to 8ft depth. The dredged material was sorted in a dewater basin on land and then trucked to a County Facility for the State to re-use the high quality material for other State projects.
The project had unique conditions that AMC overcame using our over 50 years of experience dredging in the State of Hawaii. Conditions like high currents from rain runoff, rough water conditions, monsoon rain storms, as well as floating debris that interrupted dredging operations.
AMC has been doing business in the State of Hawaii since 1975 performing specialized projects like the one at Wailoa.
