Identifying what actually needs a shutdown
Not everything above head height requires the operation to stop. Ledges and surfaces reachable from a step within the office itself can be handled in a routine attendance. What needs a shutdown is work requiring access equipment positioned in an operating area, work that will drop dust onto stock or equipment below, and anything that blocks a route used by vehicles.
Separating those two categories is worth doing carefully, because shutdown slots are expensive and scarce. A schedule that requires a shutdown for work that could have been done from within the office wastes an opportunity that may not come again for months. Walking the site and dividing the high-level tasks into the two groups usually takes very little time.
