Shimabukuro, Endo & Yoshizaki, Inc., doing business as S E Y Engineers, is an Asian-Pacific American-owned, minority-owned small business headquartered in Honolulu, Hawaii, that specializes in architect-engineer and civil engineering services for Department of Defense facilities. The firm has been registered in SAM.gov since January 2002 and maintains a corporate structure as a for-profit subchapter S corporation. S E Y Engineers provides comprehensive design-bid-build construction packages, architectural and engineering solutions, and infrastructure improvement services primarily to the U.S. Navy, with a demonstrated track record of delivering critical infrastructure projects throughout Hawaii, particularly at Joint Base Pearl Harbor-Hickam.

S E Y Engineers has received seven delivery orders under its primary indefinite-delivery/indefinite-quantity contract vehicle, collectively valued at approximately $7.3 million through July 2025, all issued by the Navy Installations Command and Naval Facilities Engineering Command without set-aside designations on an unrestricted competitive basis. These delivery orders encompass a diverse range of civil engineering and architectural services, including airfield parking apron repairs ($2.47 million), taxilane rehabilitation in two phases ($1.39 million), taxiway repairs for the 15th Wing/Hickam Airfield ($1.29 million), water line replacement near the O'Malley Gate ($715,424), drainage and site improvements for Kuntz Avenue ($648,048), lift station rehabilitation ($571,373), salt water and waste water collection and conveyance system repairs ($491,954), and sewer replacement at Sierra Pier ($491,977). All contract work has been performed in Honolulu, Hawaii, utilizing firm fixed-price pricing structures with performance periods extending through 2029. The contractor has competed exclusively on an unrestricted basis, demonstrating its capability to win awards without small business set-aside protections.

S E Y Engineers holds a five-year, $15 million single-award indefinite-delivery/indefinite-quantity contract awarded by the Naval Facilities Engineering Command on September 1, 2022, with an ultimate completion date of August 31, 2027. Although the IDIQ contract itself was awarded under a total small business set-aside solicitation, the individual delivery orders issued under this vehicle have been awarded on an unrestricted competitive basis, indicating the contractor's demonstrated competitive strength in the federal contracting marketplace. The contract vehicle authorizes the Naval Facilities Engineering Command and Navy Installations Command to issue task orders for architect-engineer services supporting various civil engineering projects and infrastructure improvement initiatives at Navy installations throughout Hawaii. With approximately $7.3 million in delivery orders already issued against the $15 million ceiling, S E Y Engineers has established itself as a qualified and reliable partner for the Navy's ongoing infrastructure maintenance and modernization requirements across Pacific installations, with substantial remaining capacity under the contract through its August 2027 expiration.
