Fukunaga & Associates

What Fukunaga & Associates does

Fukunaga & Associates, Inc. is a Honolulu-headquartered civil and environmental engineering consulting firm founded in 1969 by Royce S. Fukunaga. The firm serves federal, state, county, and municipal government agencies across Hawai'i and the broader Pacific, alongside U.S. Department of Defense clients (NAVFAC) and select private and educational institutions. Its service portfolio spans general civil engineering (infrastructure development, highways, drainage, harbors, athletic and educational facilities), wastewater systems (treatment, pump stations, collection systems, infiltration and inflow studies, reclaimed water), and water systems (resource management, master planning, storage, transmission, distribution, source development).

Technically, Fukunaga & Associates differentiates through advanced trenchless construction methods rather than proprietary software products. The firm engineered the first Vertical Shaft Sinking Machine application in a U.S. design-bid-build framework (using Herrenknecht equipment), developed 3D Finite Element Modeling for microtunneling analysis beneath Honolulu Harbor, deployed dual-bore horizontal directional drilling with underwater splicing at Pearl Harbor, and pioneered long-pull HDD installations using HDPE pipe. It also integrates Cured-In-Place Pipe rehabilitation, hydraulic and GIS modeling, and SCADA-connected solar-powered monitoring systems. Flagship projects include the $116.7M Ala Moana Wastewater Pump Station Force Mains #3 and #4 (Honolulu's largest sewage conveyance facility), the Ford Island Waterline Replacement, the Pearl Harbor Channel Underwater Waterline Crossing, the Kīhei Effluent Reuse System on Maui, the Kāne'ohe Bay Drive Trunk Sewer Reconstruction, and the 20-year $890M Long Range Sewer Rehabilitation Plan for the City and County of Honolulu's 1,800-mile wastewater collection system.

The business model is professional services engagement: project-based consulting fees driven by RFP responses, competitive bidding, and negotiated contracts with government clients — not subscription, transaction, or recurring-revenue pricing. The firm bills for feasibility studies, planning, design, project management, and construction consultation. Its primary segments are government agencies (vertical, primary) and DoD / NAVFAC (vertical, primary), with smaller exposure to private educational institutions and non-profit developers. Revenue, pricing, and backlog are not publicly disclosed. The firm operates from a single Honolulu office and grew from 11 to 50 employees with no parent company, external investors, or M&A activity; leadership transitioned from founder Royce Fukunaga to Jon K. Nishimura (2007) and to current President Jon T. Muraoka (2019), with Clifton J. Miyasaki promoted to Vice President in 2022.
