The factory building must undergo inspections prior to being put into use. As construction requires proof of compliance before operation, obtaining this proof entails a safety inspection of the factory.

The commissioning of the factory must be carried out under safe conditions. With a safety inspection and certification report, it can be proven 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 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 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 identify defects such as blowholes, slag inclusions, arc pit cracks, and arc burns.

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

Based on the actual on-site factory testing data and design requirements, in accordance with the 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 the national code requirements and the future safety usage demands.

Based on inspection, testing results, and calculations, assess the current reliability grade of the factory building in accordance with whether the structural safety meets current usage requirements. Additionally, provide reasonable recommendations for components that do not meet safety usage standards or are currently experiencing structural damage.

Facilities must undergo inspections after disasters. Post-fire, the current condition of the factory is unknown, and relevant departments will only allow it to continue operation once it's deemed safe. An assessment and analysis of the fire is required, necessitating a factory inspection and certification.

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 operation.

Factory building structures with safety hazards also require inspections and appraisals. When issues with the factory building structure are discovered, inspections and appraisals 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.
