The frequency of inspection for a space frame structure depends on several factors, including its age, location, usage, and environmental conditions. Generally, the following guidelines can be followed:
New Structures:
    For newly constructed space frame structures, an initial inspection should be conducted shortly after completion to ensure proper installation and identify any potential issues.
    Follow-up inspections may be scheduled within the first year to monitor for any settling or movement.
Regularly Used Structures:
    In normal circumstances, a comprehensive inspection of a space frame structure should be performed at least once every 1 to 3 years. This inspection should include a visual examination of the entire structure, checking for signs of damage, corrosion, or wear.
    If the structure is located in an area with harsh environmental conditions (e.g., near the coast, in an industrial area with high pollution), more frequent inspections may be necessary, perhaps every 6 months to a year.
Highly Critical Structures:
    For space frame structures that are critical to public safety or have high usage levels (such as stadium roofs or airport terminals), inspections may need to be more frequent. In some cases, inspections could be scheduled every few months or even on a continuous monitoring basis using sensors and automated systems.
After Extreme Events:
    Following an extreme weather event (such as a hurricane, earthquake, or heavy snowstorm), a detailed inspection of the space frame structure should be conducted as soon as possible to assess any damage and determine if repairs are needed.
    It's important to note that these are general guidelines, and the specific inspection frequency should be determined by a qualified structural engineer or inspector based on a thorough assessment of the individual structure and its circumstances.
