Final answer:
When attempting to fill the work platform area with planking, the maximum allowable space between your last plank and the end/edge posts of the scaffold frame is generally recommended to be around 6 to 8 inches. The maximum allowable space can also be determined based on certain guidelines related to the dimensions of the planking.
Step-by-step explanation:
In construction, when attempting to fill the work platform area with planking, it is important to ensure the widths work out perfectly. If they don't, the maximum allowable space between your last plank and the end/edge posts of the scaffold frame is generally recommended to be around 6 to 8 inches.
An older "rule of thumb" suggested 5 side-to-side and 7-8 deep, but newer recommendations suggest as much as 8 diameters side-to-side and 15 diameters deep.
