Hawaiian Dredging Construction Company

What Hawaiian Dredging Construction Company does

Hawaiian Dredging Construction Company is a private, Hawaii-based heavy-civil general contractor founded in 1902 and headquartered in Honolulu. The firm operates with a headcount estimated between 501 and 1,000 employees and is one of the longest-tenured construction firms in the state. Its service mix centers on general contracting for public-sector capital improvement projects, with verifiable recent work concentrated at the Kailua Regional Wastewater Treatment Plant and other City and County of Honolulu infrastructure assets.

Hawaiian Dredging's revenue mechanics are anchored in competitive public bidding, where the firm prequalifies on municipal and state infrastructure solicitations and is awarded fixed-price construction contracts. Documented awards include a $23.6 million biotower rehabilitation at the Kailua wastewater facility (groundbreaking June 18, 2026) and additional Kailua capital improvement work bringing combined recent awards above $85 million. The customer base is concentrated in government infrastructure clients, principally the City and County of Honolulu.

The firm operates exclusively in Hawaii and has no disclosed product surface beyond construction execution, no proprietary technology platform, and no out-of-state footprint. No acquisition activity, funding events, or M&A signals are present in the available information.
