Wilson Okamoto

What Wilson Okamoto does

Wilson Okamoto Corporation is a privately held, multi-disciplinary planning and engineering firm headquartered in Honolulu, Hawaii, founded in 1947 as Law & Wilson. The company delivers three integrated service lines — Civil Engineering (site development, water/wastewater systems, drainage, subdivision design), Transportation (traffic impact analysis, transportation master planning, traffic simulation, traffic demand modeling, traffic signal design, ADA compliance), and Planning (environmental assessments, EIS preparation, entitlements, federal/state/county permitting including HRS Chapter 343, NEPA, and Section 106 compliance) — to both public sector clients (State of Hawaii DOT, City & County of Honolulu, U.S. military) and private developers (Howard Hughes Corporation, Marriott, Castle & Cooke, Alexander & Baldwin).

Its revenue model is project-based professional services consulting, with work acquired through professional reputation, RFP/RFQ responses, and long-standing client relationships across Hawaii and the broader Pacific Basin (notably Guam). The firm operates from a single Honolulu headquarters (1907 South Beretania Street) with a wholly-owned technical services branch in Makati, Philippines (WOC Technical Services, est. 2012), and is controlled by the Okamoto family under CEO Gary Okamoto and President Michael Fujita. Wilson Okamoto has no disclosed proprietary software platform; the underlying capability is its bench of licensed professional engineers and planners delivering technical services in a heavily regulated regional market. The firm has accumulated an extensive award record from ACEC Hawaii, ASCE, APWA, and APA over more than two decades.

Commercially, the firm sells through direct enterprise engagement (RFP/RFQ-driven), is sustained primarily by government infrastructure outlays and Hawaii/Pacific Basin real estate development cycles, and earns fees in the professional services model. No external institutional ownership (PE/VC) or public market listing has been disclosed.

Core offering

Wilson Okamoto Corporation is a full-service, multi-disciplinary planning and engineering firm providing civil engineering, transportation, and planning services from feasibility through construction.

Product overview

Wilson Okamoto Corporation is a full-service, multi-disciplinary planning and engineering firm offering a unified suite of professional services rather than a software product. The company provides three interconnected service lines: Civil Engineering Services (covering site planning, infrastructure master planning, water and wastewater systems, drainage and flood control), Transportation Services (encompassing traffic impact assessment, transportation master planning, traffic simulation, traffic demand modeling, and traffic signal design), and Planning Services (including environmental impact documentation, entitlements and permitting, and master planning). These services are delivered through collaborative project teams of planners and engineers who work from feasibility through design, permitting, and construction phases.

Broad incumbents

• WSP USA: Global engineering consultancy with active Hawaii and Pacific operations in transportation and environmental planning. Larger and broader in scope than Wilson Okamoto but directly competes for transportation and infrastructure mandates.
• HDR Inc. Major engineering and planning firm with transportation and water infrastructure practices active across the Pacific. Broad incumbent that occasionally competes with Wilson Okamoto on large-scale Hawaii DOT, water, and federal work.
• AECOM: Global engineering, planning, and environmental consulting firm with a significant Honolulu office and Hawaii-Pacific portfolio. Competes with Wilson Okamoto on larger state, federal, and master-planned community projects, but operates at vastly greater scale across many sectors.
• Parsons Corporation: Large federal and infrastructure engineering firm active in DoD and Pacific theater work (Guam, Schofield). Competes with Wilson Okamoto on federal military projects but operates globally across defense, transportation, and critical infrastructure.
• Kimley-Horn: U.S. engineering consulting firm with strong transportation, traffic, and land development practices. Competes with Wilson Okamoto's transportation and planning groups on private developer work; larger national footprint but not deeply embedded in Hawaii regulatory process.
