This project involves the construction of a Modular Office Checking Post, designed to serve as a site office and security checkpoint with a compact yet functional layout. The building measures 2.30 × 8.00 meters and includes an integrated restroom to provide convenience for daily operations. Manufactured under a controlled factory environment, the modular system ensures consistent quality, reduced on-site construction time, and fast installation, making it suitable for factories, construction sites, logistics hubs, and access control areas.
