Scaffold Debris Netting: Vertical Drops, Rolls, Ties, Area & Mass for a Facade

Netting is hung in drops from the top. Every drop overlaps the next, and a roll gives only whole drops.

Drops hang from the top of the scaffold to the base, each overlapping its neighbour by the lap you enter; the run, height, extension and tie spacing are the scaffold design's. Ties are counted up every seam and both outside edges at the tie spacing, with one at each end; ties along the top and bottom rails are extra. A roll gives only whole drops, and the end of each roll too short for another drop is offcut. Returns round corners are counted in the run. **Netting adds wind load to a scaffold: the scaffold must be designed for netting before any is hung, which this tool does not check.**
