About this file

Written by GovTribe AI · Jul 15, 2025

The file contains engineering design plans and technical specifications for the Kahauiki Stream Maintenance Dredging Phase 2 project located at Fort Shafter Flats on the island of Oahu, Hawaii. The project involves dredging two sections of Kahauiki Stream (Kahauiki Stream A and Kahauiki Stream B), with a base bid to dredge the stream and clean out two existing culverts, and an optional bid to demolish and replace those culverts. The total dredging quantities are approximately 2,526 cubic yards across both stream sections, with disturbed areas totaling approximately 32,129 square feet.

The project includes comprehensive environmental and construction requirements, such as installing turbidity curtains, implementing erosion control measures, establishing temporary construction staging and dewatering areas, and transporting dredged materials to PVT Landfill. The design documents detail specific dredging limits, cross-sections, site plans, and structural elements like new concrete headwalls and guardrails. The U.S. Army Corps of Engineers, Honolulu District will solicit this as a small business set-aside contract with a projected period of performance of 533 calendar days. The estimated project magnitude is between $1,000,000 and $5,000,000, with award anticipated to be based on lowest price technically acceptable criteria.
