You need to calculate the maximum live load of a scaffolding before you erect it, so you can choose the right type of tubing, bracing and planks for the job. A scaffold live load is the weight of the workers, equipment and materials which will be used on at any one

The load that is placed on your deck is expressed in pounds per square foot (psf) and the total load or more appropriately, the design load, is comprised of the dead load and the live load. Dead load is basically the load created by the weight of the deck itself.
