[Case Study of Wooden Facility Renovation] Okinawa Prefectural Comprehensive Sports Park Pedestrian Bridge
Appropriate renovation proposals are possible! Introducing a case where FRP materials were used for the renovation of wooden bridge railings.
We would like to introduce a renovation case of the "Okinawa Prefectural Comprehensive Sports Park Connecting Bridge (Okinawa City, Okinawa Prefecture)." The handrail section of the bridge spanning the pond within the Okinawa Prefectural Comprehensive Sports Park had corroded, necessitating replacement work. Among various material comparisons, FRP (Fiber Reinforced Plastic) was chosen for its high durability against UV rays and salt damage, allowing for long-term use. It blends well with the surrounding landscape and has become a beloved new bridge. 【Renovation Case】 ■ Renovation Details: Bridge Wooden Handrail Section ■ Materials Used ・Handrail: Bongoshi Wood → FRP Our company is capable of providing appropriate renovation proposals by combining various materials such as steel, aluminum alloys, FRP, recycled wood, and natural wood.

Company information
■FRP materials that are lightweight, have high strength per unit weight, are corrosion-resistant, and are strong against salt damage. ■Pin foundation bases that do not require heavy machinery and do not need excavation of the ground surface. Our company has introduced these two technologies ahead of other companies in Japan and boasts a wealth of construction achievements. We are involved in the design and construction of bridges, decks, boardwalks, and piers in national parks and theme parks that are well-known to everyone. By partnering with a Dutch company and introducing new technology using FRP materials, we have made it possible to construct long-span FRP bridges, which were previously difficult to achieve. Furthermore, a durability of over 60 years is expected, making this a technology that can open up new markets in the future.
