This project involves an outdoor billboard owned by a well-known advertising company in Shenzhen. To assess the current quality and safety status of the billboard and to handle the city management extension of use permit, the client has entrusted our company to conduct on-site inspections. After on-site examination, we have conducted a structural assessment based on the actual conditions and conclude that the main structure of the billboard is currently free of safety hazards. However, there are signs of rust on some steel components. We recommend that the client have the rust removed before normal use.

The principal, after the de-rusting process, successfully registered and obtained an extension of use by presenting our company's inspection and identification report to the local urban management bureau.
