In civil engineering sites, the size of heavy machinery used for the installation and removal of ground plates also affects construction efficiency and costs. Heavy steel plates may require large machinery, but depending on the site, issues such as workspace and machinery arrangement can arise. Hyper CLT ground plates are civil engineering materials utilizing wood CLT. The 5×10 plate weighs about 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery. They can be widely used as alternatives to steel plates for temporary roads, access routes, heavy machinery work yards, material storage areas, and mud prevention measures. Due to their lightweight nature, they are easy to move and replace on-site, leading to labor savings and reduced work time. Additionally, they offer unique advantages of wood, such as glare reduction, noise suppression, and CO2 fixation. These wooden ground plates are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for construction efficiency, safety measures, environmental considerations, and innovative ideas in public works.

In civil engineering sites, workers often stand for long periods and move repeatedly between material storage areas, break areas, and work locations. Uneven ground or muddy areas can make walking unstable, which may increase the burden on the feet and lower back as workers try to protect their footing. Hyper CLT mats are civil engineering CLT materials that utilize laminated CLT wood. By laying them down in worker pathways, assembly areas, around break areas, and material storage sites, they can reduce ground unevenness and mud, ensuring stable walking paths. Creating a more walkable surface helps reduce the burden on workers' feet and prevent falls. The 5×10 panels weigh approximately 230 kg, and the 5×20 panels weigh about 460 kg, making them lightweight and easy to handle even with small machinery, which also contributes to labor-saving in installation and removal. Additionally, they have unique characteristics of wood, such as glare reduction, noise suppression, and CO2 fixation. These wooden mats are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for safety measures, improving work environments, and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

When introducing sheet boards at civil engineering sites, it is important to check not only the product price but also the transportation costs, including the number of trucks and the number of trips. The more sheets required at a site, the more the number of sheets that can be loaded onto one truck affects the overall cost of the project. The 5×10 version of the civil engineering CLT material "Hyper CLT Sheet Board," which utilizes wood CLT, weighs approximately 230 kg per sheet. A 10-ton truck can carry a maximum of 40 sheets, transporting about 180 square meters with one trip. This allows for efficient delivery of a substantial number of sheets, reducing the number of trucks and round trips, which leads to lower transportation costs. It is lightweight and easy to handle even with small machinery, effectively reducing the burden of unloading, installation, and removal. It can be widely used in various civil engineering projects as an alternative to steel plates for temporary roads, access routes, heavy machinery work yards, and mud prevention measures. It is a wooden sheet board registered as a Ministry of Land, Infrastructure, Transport and Tourism NETIS technology "TH-250021-A," which simultaneously enhances transportation efficiency, workability, and environmental consideration.
