Building Facade Safety Inspection

Continuous incidents of curtain wall hazards have occurred. To enhance prevention, reduce damage, and ensure urban safety, users should regularly inspect and test the safety of the curtain wall.

A building facade refers to the outer protective system of a building composed of panels and supporting structures, which has a certain displacement capability relative to the main structure. In addition to transmitting its own loads to the main structure, it does not bear the effects exerted on the main structure.

The inspection and evaluation of building curtain walls should be conducted according to the following procedures:

1. Commission

2. Inquiry

3. Develop inspection and testing plans

4. Inspection and Testing

5. Calculation and Analysis

6. Inspection and Evaluation Report.

The client shall provide technical documents for engineering design, construction, and use, and determine the content of the inspection and evaluation with the inspection party. When entrusting inspection and evaluation, formulating, and negotiating inspection and detection plans, the responsibilities and risks of the client and the inspection party should be clearly defined.

The survey should include the following tasks:

1. Project Overview: Includes the start and completion time, engineering structure, construction unit, design unit, construction unit, supervision unit, etc.

2. Technical Documents: Including completion drawings of curtain wall engineering, structural calculation books, design change records, etc.

3. Construction Quality Assurance Documents: Including completion reports, concealed work acceptance records, quality inspection records of construction work, material quality assurance certificates, and material retest reports, etc.

4. Building Facade Usage Records: Including daily maintenance and repairs, condition logs, renovation completion technical documents, etc.

5. On-site adjustments include: verifying physical items against documentation, investigating the actual internal and external environment of the building, identifying existing issues, and collecting opinions from relevant personnel.

Based on the various documents and investigation information provided by the client, determine the key items for inspection and testing. Develop a testing and evaluation plan, which should include the content, methods, and progress of the inspection and testing.

Building Facade Inspection and Testing Services:

1. Initial Condition Inspection: Facade system, structure, key joints, and opening sash installation quality.

2. Current Status Inspection: panel and connection component damage, rust, deformation, and extent of hardware failure.

3. Material Testing: Panels, metal profiles, silicone structural sealant, stone adhesive, sealing materials, fire-resistant insulation materials, hardware, precast components, and post-installed anchors, etc.

4. Structural and Construction Inspection: Load-bearing members and structures, panel assembly components, etc.

5. Structural Load-Bearing Verification: Verification of loads acting on the container wall, their effects, and node checks.
