Post-disaster building quality includes the calculation and analysis of the structural condition of buildings after damage from disasters such as floods, fires, and earthquakes.

Content Inspection
 

1. Determine the extent of disasters, such as rainfall coefficients, fire temperature fields, and earthquake magnitude and intensity; based on the degree of damage to the property, the type, quantity of combustible materials, and infer the scope and scale of the fire.

2. In cases of necessity, take samples of the damaged parts of the damaged components for microscopic testing to determine the extent of damage to the structural elements.

3. Utilizing on-site testing equipment, a comparative inspection is conducted between the damaged components and their corresponding undamaged counterparts.

4. Conduct an appearance survey of the damaged structural components, preliminarily determine the temperature distribution and extent of damage as well as the scope.

5. Determine the structural mechanics model, conduct structural load-bearing calculations, and establish structural reinforcement plans.

One, Post-fire Building Quality Inspection and Assessment
 

As urbanization accelerates across provincial capitals and major cities like Beijing, Shanghai, Guangdong, and Shenzhen, an increasing number of buildings with unique designs, complex structures, and multiple stories are popping up, resulting in skyscrapers dominating the skyline. In recent years, there has been a rise in urban fire incidents, with fires in high-rise buildings posing particularly severe risks. Regardless of whether the fire occurs in high-rise residential buildings, multi-story housing, industrial factories, office buildings, or steel structures, the aftermath of a fire often leads to significant damage to the structural integrity of the buildings.
 

Fire can significantly impact the quality of buildings, with severe cases posing an immediate risk of collapse. The types of building structures include reinforced concrete, brick and concrete, and steel structures. Regardless of the structure, fires have a profound effect on the safety of the building. Particularly for steel structures, a severe fire can completely engulf the entire structure, as steel is prone to bending when exposed to heat. Frame structures experience weakened concrete strength and bending of steel upon fire, leading to quality issues in beams, columns, and floors, which can result in building collapse.

Post-Fire Property Inspection and Reinforcement Repair Procedures

In accordance with the "Post-Fire Building Structural Evaluation Standard" (CECS 252:2009), after a fire in buildings such as factories and office buildings, a professional building quality inspection and evaluation agency must conduct post-fire structural inspections. This involves on-site structural and safety assessments, clearly defining the quality status of the affected areas, and determining whether the post-fire building can be used further and whether structural reinforcement is needed. We offer reinforcement solutions tailored to damaged buildings. The structural reinforcement design unit will design and draw the reinforcement plans, and the construction unit will reinforce the factory to meet the safety standards for continued use.

Post-Fire Home Inspection and Reinforcement

Considering the economic costs for the property owner, when a factory building is unusable due to a fire, targeted structural reinforcement is conducted after inspection by a professional property assessment company, which requires significantly less capital investment compared to the cost of demolition and reconstruction. In such cases, if insurance compensation is involved, an after-fire quality inspection report from a local professional property assessment company is also required. A comprehensive inspection and assessment of the factory's damage situation is carried out. Having discussed so much about the situation after a factory fire, what specifically does the post-disaster factory inspection and post-fire building safety inspection and assessment involve?
