About this file
This announcement constitutes a solicitation for the Kaunakakai Harbor Maintenance Dredging project in Molokai, Hawaii and the Kahului Harbor Maintenance Dredging project in Maui, Hawaii. The U.S. Army Corps of Engineers, Honolulu District intends to issue a solicitation to conduct maintenance dredging by mechanical clamshell dredge to remove accumulated sediments within the harbor federal limits at both locations. The Kaunakakai Harbor project requires dredging an estimated 35,000 cubic yards of material to a depth of -23 feet MLLW, while the Kahului Harbor project requires dredging an estimated 158,000 cubic yards of material to a depth of -35 feet MLLW. Offerors must have an active SAM registration and the combined period of performance is estimated at 18 months. The solicitation will utilize LPTA procedures and be set aside for small businesses. The NAICS code is 237990 and small businesses must self-perform at least 40% of dredging volume. The award will be a fixed-price construction contract between $5-10 million.
