Formwork edge boards.
Measure each separate edge run and the board face that will contact the pour.
Read the right quantitative data
Actual board height, usable stock lengths and supplied cutting allowances.
Check this ordering assumption
A shared edge is not two independent boards, while corners may consume additional cutting length.
Document shared runs and separately supplied details before counting stock.
