Now, there's an increasing number of factory buildings being constructed, with a wide range of functional uses and varying structural designs.

Regardless of the factory structure, a factory inspection and appraisal is required. When exactly is a factory inspection and appraisal needed?

Factory construction must be inspected before it is put into use. Because before the building is put into use, it is necessary to...

Factory safety inspections are conducted. The commissioning of the factory must be carried out under safe conditions, and a safety inspection and certification report is required.

Proof that the factory is ready for normal operation.

Factory inspections are required after a disaster strikes the factory building. After a fire, the current condition of the factory is unknown, and the relevant departments are

The factory must be deemed safe before resuming operations. A room that has been affected by a fire requires an assessment and analysis of the incident.

It's time to conduct an inspection and assessment of the factory. Through the factory inspection and assessment, we can determine the extent of damage to the factory after the fire and whether the structure has been compromised.

Question: Can it still be used continuously?

Factory building structures with potential safety hazards also require inspection and appraisal. When issues with the factory building structure are discovered, a detection and appraisal should be conducted.

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

Based on the current national standard "Reliability Assessment Standard for Industrial Buildings" (GB regulations), the reliability assessment of industrial buildings is conducted according to components and structural systems.

The identification unit is divided into three levels, each with four grades. The grading criteria and corresponding handling for reliability identification rating of each level of the evaluation items are as follows:

Requirements as follows:

Grade 1 (A-grade, a-grade) — Meets the reliability requirements of the current national standards and regulations without affecting overall safety; does not impact the overall integrity within the targeted service life.

Normal use may require appropriate measures for a very few minor components.

Grade B (B-Level, b-Level) — Slightly below the reliability requirements of the current national standards and specifications, still meets the minimum level requirements for structural reliability, yet not obvious.

Affects overall safety; does not impair or has not yet significantly impaired overall normal use within the intended service life; a few components may require measures, and an extremely small number may need attention.

Minor components must be addressed immediately.

Grade 3 (C-grade, c-grade)—Does not meet the reliability requirements of the current national standards and specifications, affecting overall safety; significantly impacts overall performance within the intended service life.

Normal operation requires taking measures, and in extremely rare cases, certain components may necessitate immediate action.

Level 4 (D, d) — Significantly fails to meet the current national standards and specifications for reliability, severely affecting overall safety; immediate measures must be taken.
