Construction: Temporary structure question

[yatkins]

The number of levels of shoring vs reshoring will depend on the schedule. 1 level shoring, 2 of reshoring is cheaper since it requires 1 less set of forms, but you can't replace shoring/forms with reshoring until the slab has reached sufficient strength. However, you may be ready to form the next floor slab before you can remove the forms of the floor below so you'd need the extra set of forms.
