The registration authority is the Shenzhen Market Supervision Administration Bureau, and the legal representative is Li Yongjiang. The business scope includes general projects such as: , and permitted projects such as: building safety inspection and appraisal, building structure inspection and appraisal, steel structure inspection and appraisal, on-site main structure inspection, construction project quality and material inspection, indoor environmental inspection of buildings, and building energy saving inspection.

The project is located in Fujian, and is a newly constructed steel structure factory under a state-owned enterprise. Although the project was recently completed, cracking on the ground has been discovered during use. To assess the safety of the steel structure's main structure, on behalf of the client, our company has dispatched professional personnel for on-site inspections.

Upon on-site review of the design drawings, the cross-sectional dimensions and floor layout of the building's main structural components are in compliance with the design requirements.

On-site inspection of the construction nodes such as weld joints and bolt final tightening strength has been conducted, which generally meets the specifications and design requirements.

The verticality of the steel columns in the building has been inspected, and they are within the allowable range as per the specifications.

The component coating thickness has been inspected and generally meets the specifications. No visible structural cracks were found in the main structure of the building.

Upon inspection of the cracking on-site ground, it was found that a significant portion of the backfilled soil in the building has subsided.

After comprehensive testing and analysis, it is believed that the ground cracking is primarily due to the subsidence of backfill soil. Currently, it has not caused deformation or harm to the main structure. It is sufficient to treat the backfill soil and then monitor its use.

The principal has treated the building's ground according to the conclusions and recommendations in our company's report. Currently, the building is being used normally, and no abnormal phenomena have been detected.

The client originally planned to either reinforce the structure or demolish and rebuild it. After referring to our company's inspection and appraisal report, millions were saved while ensuring safety.
