When Are Site-Specific Drawings by a Professional Engineer Required?
When working on a suspended access platform, it’s important to ensure that the equipment is safe and stable. Site-specific drawings by a professional engineer are often required to guarantee that the platform is appropriately designed for the specific site.
Here are some situations when site-specific drawings are typically required:
- When the building structure has unusual characteristics or the attachment points are not easily accessible.
- When the platform will be used for more than one trade or purpose.
- When the platform is suspended from a structure that has not been previously designed to accommodate it.
- When the platform requires additional anchorage or support.
- When the platform is being used in a seismic zone.
To ensure compliance with safety regulations, a professional engineer must provide drawings that outline the platform’s design and configuration. These drawings should include information such as:
- The maximum weight capacity of the platform and the supporting structure.
- The placement and quantity of outriggers and other stabilization components.
- The type and strength of wire ropes, safety lines, and other essential components.
- The method of attachment to the building or structure.
- The location and size of attachment points.
- The method of access and egress from the platform.
- Any additional safety features that are required for the specific job site.
It’s important to note that site-specific drawings should be kept on the job site at all times and made available to the relevant parties, including workers, supervisors, and safety inspectors. Any changes to the platform or its supporting structure must be approved by a professional engineer before implementation.
By following these guidelines and ensuring that site-specific drawings are obtained and followed, workers can safely use suspended access platforms while working at heights.
