Explain the process to estimate the number of ties needed for a wall form.
Determine # of rows horizontally:
Height of wall divided by O.C. spacing *round up + 1 = # rows horizontally

Perimeter divided by O.C. spacing *round up + 1 = # rows vertically
#rows vertically X #rows horizontally = total # of ties needed
