Factory construction must undergo inspections before being put into use. This is because a certificate is required prior to the building's operation, and obtaining this certificate entails a safety inspection of the factory.

The occupancy of the factory must be conducted under safe conditions; with a safety inspection and certification report, it can be proven that the factory is fit 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 exterior damages of factory steel components, including cracks, damage, coating peeling, steel corrosion, joint injuries, welding appearance defects, and connection fastening conditions.

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

Inspect and evaluate deflection deformation of trusses, girder, and their members using total station or stringing method. Evaluate the strength of steel using the surface hardness method.

Based on actual on-site factory testing data and design requirements, and in accordance with national building structural design codes, we calculate the load-bearing capacity of the factory's upper structure to assess whether the current load-bearing capacity meets national code requirements and future safe operation needs.

Based on the inspection, testing conditions, and calculation results, assess the current reliability level of the factory building according to whether its structural safety meets the current usage requirements, and propose reasonable treatment suggestions for components that do not meet the safety usage standards and those currently showing structural damage.

Factory inspections are mandatory after a disaster. After a factory has suffered a fire, the current condition of the factory is unknown, and relevant departments will only allow continued use once the factory is deemed safe. An assessment and analysis of the fire is required after a factory experiences a fire, at which point a factory inspection and certification is necessary.

Through factory inspection and assessment, it can be determined the extent of damage to the factory after the fire, whether the structure has issues, and if it can still be used for operations.

Safety hazards in the factory structure also require a formal inspection and assessment. When issues with the factory structure are identified, a detection and assessment must be conducted.

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