also that the start of this activity lags 1 day behind the start of the slab activity. This makes the plumbing activity
completely contained within the slab activity.
f fMake this activity a finish milestone.
g Insert a constraint so that site work will not finish umtil about 1 week before the end of the entire project.
h Certiicate of occupancy.
i If blank, then the lag is zero.
