Okahara & Associates, Inc.

Okahara & Associates, Inc., headquartered in Hilo, Hawaii, is a minority-owned small disadvantaged business that specializes in providing architect-engineer services to the federal government. The firm, registered in SAM.gov since September 18, 2001, operates as a corporate entity focused on civil, mechanical, and landscape architecture services. Okahara & Associates has positioned itself as a key provider of infrastructure design, engineering studies, facility improvements, and construction support services primarily for Department of Defense installations throughout Hawaii and the Pacific region.

Through its federal contracting history, Okahara & Associates has delivered a comprehensive range of architect-engineer services across multiple military installations. The company has executed delivery orders totaling over $12.8 million from the U.S. Army Corps of Engineers Engineering District Honolulu for civil engineering projects including water infrastructure repairs and replacements at Tripler Army Medical Center ($2.66 million), pump station and water line repairs at Fort Shafter ($2.06 million), water storage tank repair at Kwajalein Atoll in the Marshall Islands ($1.71 million), Kahauiki Stream Phase 2 feasibility work ($606,098), and NSA erosion control work at Kunia, Oahu ($578,928). Additional delivery orders have supported drainage and erosion studies, pump station upgrades, bridge repair designs, and facility stabilization projects at military installations including Schofield Barracks and McCornack Gulch. The company also received a $2,500 delivery order from the U.S. Air National Guard under a Hawaii IDIQ architect-engineer MATOC contract and a $13,245 purchase order from Pacific West Area for HVAC system inspection services. All delivery orders have been structured as firm fixed-price contracts without specific socioeconomic set-asides, with performance primarily taking place at Fort Shafter, Hawaii and other Pacific region locations.

Okahara & Associates currently holds three indefinite delivery contracts that serve as primary vehicles for federal architect-engineer services. The company maintains a $190 million Indefinite Delivery Contract (IDC) with the U.S. Army Corps of Engineers Engineering District Honolulu, awarded January 30, 2025, with completion through February 23, 2030, designated as a total small business set-aside contract for architect-engineer civil services supporting design, studies, repairs, modifications, rehabilitation, and new construction across the Honolulu District's area of responsibility. Additionally, the firm holds a $12 million multiple-award indefinite delivery contract with the Army Corps of Engineers effective July 1, 2022 through June 4, 2027, also designated as a total small business set-aside for Small Business A-E civil services. Most recently, Okahara & Associates was awarded a $40 million Indefinite Delivery, Indefinite Quantity (IDIQ) contract by the Air National Guard on August 29, 2025, with completion through February 28, 2031, carrying a partial small business set-aside designation. This Air National Guard contract provides architect-engineer services in support of Air and Army National Guard vertical and horizontal construction programs for Hawaii, encompassing design, engineering studies, facility improvements, infrastructure repairs, modifications, rehabilitation, and new construction initiatives.
