Stormwater Drainage and Erosion Control Design

The contract involves the hydrologic and hydraulic design of storm drainage systems, culverts, detention basins, and erosion and sediment control measures specifically tailored for construction sites in tropical environments. The work requires specialized engineering expertise to manage high rainfall volumes, rapid runoff, and soil instability common in such climates, ensuring compliance with environmental and safety standards during development. All design outputs must be optimized for performance under extreme weather conditions and must integrate seamlessly with existing infrastructure at the place of performance, Joint Base Pearl Harbor-Hickam, Hawaii, with zip code 96860. This is a subcontract under the NAICS code 541330 for architectural, engineering, and related services, issued by the Department of Defense through Navfacsyscom Hawaii. The solicitation was posted on July 16, 2026, with a firm response deadline of August 6, 2026, at 10:00 PM local time. Although no set-aside status is indicated, the scope demands proven experience in tropical hydrologic modeling, regulatory adherence, and field-applicable erosion control solutions. The successful contractor will be expected to deliver detailed engineering analyses, calculations, and drawings that support safe, sustainable, and resilient stormwater management systems on federal construction projects within this high-risk environmental zone.
