BATTERBOARD

1. To estimate the lumber to be used as batterboard for lay-out, compute the lineal meter of the structure all around giving an allowance or margin of 1.00. Count also the number of stakes tobe used. Multiply the number of stakes by 1.2 (length of stake) and add the sum to the first linealmeter change to lineal foot. Then compute the board depending to the size of the lumber to be used as batterboard (2" x 2" or 2" x 3")

2.to get number of kilos. If by keg, divide the total board foot by factor 2500 equals keg of nails.

3. To estimate guide wire #12 to be used in layouting, divide the total boardfoot by 4000 to obtain roll of wire.

Note: The Drawing below is an illustration of layout showing the location of batterboard and stake.
