Building Facade Safety Inspection

Continuous occurrences of curtain wall hazard accidents necessitate regular safety inspections and testing to enhance prevention, reduce harm, and ensure urban safety.

A building facade refers to the outer protective system of a building, composed of panels and supporting structures, which has a certain degree of displacement capability relative to the main structure. It transmits its own loads to the main structure but does not bear the loads exerted on the main structure.

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

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 commissioning inspection and evaluation, formulating, and negotiating the inspection and testing plan, the responsibilities and risks of the client and the inspection party should be clearly defined.

The survey should encompass the following tasks:

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

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

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

4. Building Facade Usage Record: Includes daily maintenance and repair, 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 the inspection and testing evaluation plan, which should include the content, methods, and schedule of the inspections.

Building Facade Inspection and Testing Services:

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

2. Current Condition Inspection: Panel and connection component damage, rust, deformation, and degree of hardware failure.

3. Material Testing: Panels, metal profiles, silicone structural sealant, stone adhesive, sealing materials, fireproof and thermal insulation materials, hardware, precast components, 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 acting on the container wall, their effects, and node verification, etc.
