Scaffolding planning Review blueprints, work orders, the project schedule and other written requirements to determine where scaffolding will be used. Next, select the right size scaffold for each job. Scaffolding is generally classified as light, medium or heavy duty. Light duty scaffolds can support a limited number of workers and hand tools (25 lbs. per square foot). Medium-duty scaffolds must be able to safely support workers, hand tools and the materials being installed (50 lbs. per sq. ft.). Heavy duty scaffolding must support workers, tools and the weight of materials being stored.
The following factors should be considered at the design stage
- The shape and structure of the building to be scaffolded.
- The particular site conditions and any special features of the building structure in relation to the scaffolding (e.g. overhead power lines or storage tanks). Also consider the proximity and condition of surrounding buildings.
- Weather and environmental conditions.
- Fall protection requirements for workers using the scaffold, such as guardrail systems or personal fall arrest systems.
- The type and quantity of scaffolding required to access all areas to be worked on.
- The correct storage and transportation of scaffolding components, materials and equipment.
- How workers will access the scaffold (i.e. ladders, stairway systems, etc.).
