OKAHARA & ASSOCIATES, INC

Okahara & Associates, Inc. specializes in civil engineering services for defense and federal infrastructure, with deep expertise in water systems, erosion control, and structural rehabilitation. Their technical focus includes hydraulic design, construction phase services, pump station repairs, water line replacements, and compliance-driven infrastructure upgrades—particularly in challenging coastal and military environments. The firm demonstrates proficiency in establishing construction phase options, conducting site-specific feasibility studies, and executing repairs to critical utilities such as water tanks, diesel motor/pump systems, and stormwater conveyance structures. Their work on Kauai and Oahu installations reflects advanced knowledge of Hawaii’s unique geotechnical and environmental constraints, including stream restoration, transite line replacement, and flood mitigation strategies. The contractor maintains a consistent relationship with the Department of Defense, delivering engineering solutions for Army and Navy installations across Pacific theater locations, including Kwajalein, Fort Shafter, and Naval Station Kaneohe Bay. Their portfolio includes both routine maintenance and complex infrastructure modernization projects, indicating a trusted, long-term partnership with military civil works teams. A single award from the Department of Agriculture highlights limited but credible experience in building inspection services, specifically for HVAC control systems, suggesting adaptability across federal facility oversight needs. Okahara & Associates operates primarily under NAICS 541330, focusing on engineering services that bridge design, construction oversight, and regulatory compliance for federal infrastructure. Their market positioning centers on mission-critical civil works in remote and high-humidity environments, with a niche in military base utilities and environmental resilience projects. They do not hold any federal certifications, and their operational base in Hilo, Hawaii, positions them as a locally embedded provider with intimate knowledge of Pacific Island infrastructure challenges. Their geographic focus and technical specialization make them a unique resource for DoD projects requiring on-site, island-specific engineering execution.
