Mobile toilet cabin safety and quality inspection

I. Construction and Structural Review

The site review of the structure's layout and construction is conducted based on the drawings and other documents provided by the client.

II. Inspection of Structural Damage Conditions

Inspect for cracks, deformations, and localized damage to the structure, and document them in writing or with photographs. Determine the location, extent, and cause of the damaged structural components, and analyze the observed damage phenomena.

Structural Load-bearing Capacity Analysis

Without considering the basic construction methods, based on the relevant information provided by the client and the current condition of the inspected portable toilet units, combined with on-site testing data, comprehensively analyze the load-bearing capacity and the wind and seismic resistance of the main structure of the inspected portable toilet units under normal usage conditions.
