Industrial facility inspection and appraisal purposes
Based on the inspection and testing of the prefabricated components of the engineering construction house, we have assessed the safety coefficient level of the structure, providing a scientific and reliable evaluation for the safe application of residential use.
Industrial Factory Inspection and Appraisal Content
Clearly define the specifications, locations, and tentative load-bearing capacities of the building.
Assessing the centerline specifications and building heights of structures, as well as evaluating the regional structural layout.
Inquire about the validity of query construction layouts and whether prefabricated components transfer forces immediately, etc.
Inspect and verify the cross-sectional specifications of concrete structural columns and beams in the testing and identification area.
Selected core sampling method for partial strength testing of concrete in columns and beams in the identified area. (Refer to Article *3 of the "Standard for Constructional Detection" GB/T 50344-2004, where core samples were sent to a decorative material testing enterprise for experiments, obtaining experimental data for reporting and verification calculations.)
Utilizing rebar detection equipment to inspect and assess the condition of the reinforcing steel in columns and beams, as well as the thickness of the protective layer.
Inspecting the precast components such as columns and beams in building identification areas for any gaps, and analyzing the causes of the gaps and whether they have caused damage to the structure.
Utilizing a vibration meter, we measured higher amplitude, higher rate, and higher instantaneous velocity values on the concrete floors of the second and third floors of the industrial plant under standard operating conditions with machinery and equipment functioning normally. We then analyzed and assessed the cause and level of damage of the vibration in that area.
Analyze the safety coefficient of existing buildings, based on our standard selection value of the driving force index, and approve the safety coefficient of buildings according to testing and certification standards.
Based on the evaluation of the physical performance of building structures, in accordance with the current bearing capacity, usage status, and building structure management system, utilizing inspection results, original design plans, and our standards, we have established a scientifically rational computational model. This model assesses the current safety and application capabilities of the house's certification area and verifies its structural measures.
An assessment of the structural safety coefficients within the designated building inspection area was conducted, adhering to standards of objectivity, science, and fairness, and a comprehensive assessment report was written, clearly presenting the findings.
