What is Outdoor Advertising Facility Inspection?

Outdoor Advertising Facility Inspection in the construction testing industry primarily refers to periodic (usually annual) or special safety inspections and assessments of billboards by qualified third-party professional organizations, in accordance with relevant national laws, regulations, and technical standards (such as the "Technical Specifications for Outdoor Advertising Facilities"). This ensures the stability and safety of the facilities during their service life, preventing accidents, and provides inspection reports to guide maintenance and rectification. The inspection content covers a comprehensive range of checks, from steel structures, connectors, corrosion protection, and electrical wiring to lighting fixtures and panel fixings.

Core Inspection Content

• Structural Safety Inspection
　　• Main Structure: Inspect the corrosion, deformation, weld quality (non-destructive testing), and tightness of connecting bolts of columns and supporting components.
　　• Foundation and Connections: Assess the stability of the foundation and the reliability of the connection supports to the building.
　　• Deformation Monitoring: Measure the displacement and tilt of the billboard using total stations and other equipment.
　　• Materials and Processes: Check the quality of materials used, anti-corrosion coatings, and component manufacturing and installation processes.

• Electrical Safety Inspection
　　• Check for problems with lighting fixtures, wiring, insulation performance, grounding resistance, leakage, and short circuits.

• Environmental and Special Protection
　　• Wind Resistance and Stability: Evaluate safety under different wind forces.
　　• Lightning Protection and Grounding: Test the effectiveness of lightning protection facilities.
　　• Fire Protection Measures: Check whether fire-resistant materials and isolation measures are in place.

• Panels and Ancillary Facilities
　　• Inspect the fixing, aging, and damage of glass panels and membrane panels.

Inspection Basis and Requirements

• Laws and Regulations: Follow the "Technical Specifications for Outdoor Advertising Facilities," "Building Structure Load Specifications," etc.
• Qualification Requirements: Must be conducted by a unit with professional testing qualifications.
• Inspection Frequency: At least one safety inspection per year; immediate inspection if hazards are found.
• Report Retention: The inspection report shall be properly kept by the owner for inspection purposes.

Inspection Process
• Application and Commissioning: The owner or manager of the advertising facility commissions a qualified testing agency.
• On-site Survey and Data Collection: Engineers conduct comprehensive inspections, measurements, and recordings.
• Indoor Analysis and Evaluation: Analyze data according to standards and determine safety.
• Reporting and Rectification: Inspection reports will be issued, and any non-compliant structures must be rectified or removed immediately.

In short, outdoor advertising facility inspection is an important branch of building inspection and a crucial link in ensuring urban public safety.
