In civil engineering sites, there are many instances where sheet boards are used for temporary roads, access roads, heavy machinery work yards, material storage areas, and pedestrian pathways. Traditional steel plates are heavy, which can require large cranes or heavy machinery for installation and removal, increasing the workload depending on site conditions. Hyper CLT sheet boards are civil engineering materials made from wooden CLT for civil use. The 5×10 board weighs about 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which allows for easier installation without the need for large cranes. They also contribute to reducing the burden of transportation, installation, and removal, as well as improving maneuverability on site. Recommended as a registered technology by the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," it is suitable for companies considering civil engineering, civil use, and civil CLT. This material is easy to use for creative proposals in public works, such as alternatives to steel plates, common temporary structures, temporary roads, and curing for material storage areas.
