Building Facade Safety Inspection

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

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 in accordance with 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 investigation should encompass the following tasks:

1. Project Overview: Includes the start and completion time, project structural form, construction unit, design unit, construction unit, supervision unit, etc.

2. Technical Documents: Including completed curtain wall project drawings, structural calculation books, and design change records.

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

4. Architectural Facade Usage Record: Includes routine maintenance and repairs, condition logs, renovation completion technical documents, etc.

5. On-site Adjustments: Verify physical items against documentation, investigate the actual internal and external environment of the building, identify existing issues, and collect 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 comprehensive inspection and testing evaluation plan, which should include the content, methods, and progress of the inspection and testing.

Building Facade Inspection and Testing Services:

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

2. Current Condition 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, fireproof and thermal insulation materials, hardware, prefabricated parts, and retrofitted embeds, etc.

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

5. Structural Load-Bearing Verification: Verification of loads and actions on the container wall, as well as node verification.
