Hawaiian Dredging resurfaced approximately five miles of the two inbound lanes of Kuihelani Highway with four-inch thick Ultra-Thin White Topping (UTW) concrete pavement. Developing a 3D model to determine the new grades and cross slopes, Hawaiian Dredging was able to integrate the model into the project to control the schedule and shorten the overall construction…
The Umauma Bridge, was originally constructed in 1911 to support railroad tracks over Umauma Stream. Hawaiian Dredging was selected to perform a full rehabilitation of the 100-year-old bridge. Perched 100 feet above the Umauma Stream, the rehabilitation involved construction of concrete towers to be placed within the existing steel support structures, widening and replacement of…
Fort Weaver Road is one of the most heavily traveled highways in the State. It was badly in need of widening with over 40,000 cars per day using a four lane road connecting Ewa with the H-1 Freeway. This project added two lanes to the existing four, giving the major thoroughfare three lanes in each…
The Interstate Route H-1 Kapolei Interchange is located on both the westbound and eastbound sides of the H-1 Freeway between the Makakilo Interchange and the Palailai Interchange (the off-ramp to the Campbell Industrial Park). This project widened lanes in both direction of the H-1 Freeway with a new 12-foot travel lane and a 10-foot shoulder…

The Papahawahawa Bridge exemplifies reverence for…
The Navy’s desire to bridge the nearly 1.5 kilometer channel between the Pearl Harbor shore and Ford Island was met by a design based on a traditional span bridge with intermediate support foundations and a movable floating section that when pulled under the main structure would create an opening through which ships could navigate. The…
The fragile quarter-mile stretch of the Pearl City Force Main near the Waipahu Pump Station was long overdue for repair. Plagued with ruptures, the main occasionally spilled sewage into residential neighborhoods causing environmental and political damage. Hawaiian Dredging won the contract for a solution to keep the main in service another 20 years. We chose…
Honolulu traffic is ranked among the worst in the nation. As part of the Hawaii Department of Transportation’s efforts to improve Oahu’s traffic infrastructure, Hawaiian Dredging was hired as the Design-Builder to install additional lanes for faster travel times and improve road conditions for smoother rides. These repairs are collectively known as the H1 PM…
Kawaihae is a major port for the island’s interisland cargo and petroleum receiving facilities. Additionally, the expansive harbor with its extensive breakwater and shoreline system is the site for a wide range of ocean activities enjoyed by visitors and residents including fishing, boating, paddling, and surfing. Hawaiian Dredging was selected to move forward with a…
The Hawaiian Department of Transportation needed a minor miracle. A bridge weighing more than 1600 tons would cross a ravine two football fields long and almost 200 feet deep. The transportation department’s initial building plan was too costly in terms of materials, complexity, and environmental impact. Extraordinary construction challenges had to be overcome, chiefly the…
