The factory building must undergo inspections before being put into use. This is because, before commencing operations, a certificate of proof is required, which involves a safety inspection of the factory.

The commencement of the factory must be conducted under safe conditions. A safety inspection and certification report can verify that the factory is ready for normal operation.

Based on the drawings provided by the client, review the steel structure layout, component dimensions, and floor heights of the factory; for those without design drawings, conduct on-site inspections of the existing upper structures, component dimensions, and floor heights of each factory building and draw structural diagrams.

Inspect and appraise the external damages of the factory steel components, including cracks, damage, coating peeling, rust on steel, node damage, welding appearance defects, and connection fastening conditions.

Selecting certain steel trusses and steel structural components in accordance with national testing and acceptance specifications, the factory is inspected using ultrasonic or magnetic particle testing for weld inspection, to determine the presence of defects such as blowholes, slag inclusions, arc pit cracks, and arc burns.

Inspect and assess the deflection deformation of trusses, rafters, and their members using total station or stringing method. Assess the strength of steel using the surface hardness method.

Based on the actual testing data from the on-site factory and design requirements, in accordance with national building structural design codes, we calculate the load-bearing capacity of the factory's upper structure. We assess whether the current load-bearing capacity of the factory meets national code requirements and the safety usage requirements for future operations.

Based on the inspection, testing conditions, and calculation results, assess the current reliability grade of the factory building according to whether the structural safety meets the current usage requirements, and propose reasonable recommendations for components that do not meet the safety usage standards or have currently shown structural damage.

After a disaster, factory inspections are required. After a factory has been affected by a fire, the current condition of the factory is unknown, and relevant departments will only allow it to continue being used once the factory is deemed safe. In the event of a fire, an assessment and analysis must be conducted, which necessitates a factory inspection and certification.

Through factory inspection and appraisal, one can determine the extent of damage to the factory after a fire, whether the structure has been compromised, and whether it can continue to be used.

Factory building structural safety hazards also require inspection and assessment. When issues with the factory building structure are discovered, an inspection and assessment must be conducted.

Due to the specialized inspections for factory structures, when issues arise, the affected structures must be inspected to eliminate potential safety hazards.
