Similarly for:
10' - 0" = 10 x 12 = 120 inches
3' - 0" = 3 x 12 = 36 inches
Then:
(4) For item 5, use a short standard
length of 8 feet since, in this instance, only one piece
= 3 pieces w/12 inches waste
is required. Item 6 is similar to item 2 and will be
listed accordingly; only the number standard lengths
Note:
If a 10-foot length was used there would be
in column 8 will be different:
48 inches waste, the unnecessary third
length (36 inches) plus 12 inches waste.
Thus for column 6, the 8-foot standard length is
chosen as it will supply the two required number of
The entries for columns items 5 and 6 are as follows:
pieces (column 3) with the least waste. Again, for
column 8, divide the number of pieces (column 3) by
number per standard length (column 7).
Hence, the developed entries for columns 6, 7, and 8
for item 2 would be:
(5) Since item 7 is 4' - 6" long (same as
items 1 and 3) select the 10-foot standard length as it
will supply two lengths with least waste. Then to
develop column 8 (number of standard lengths)
compute:
Note:
In this example, column 4 is omitted since it
is not used in the calculations.
(2) Continuing with item 2 (a(2),
Developed columns for item 7 follow:
above), observe that the item requires two pieces,
each 3' - 0" long. In selecting the standard length
(column 6) and the number per standard length
(column 7), calculate on the closest standard length
by trying an 8-foot versus a 10-foot length.
(3) Note that items 3 and 4 have the
same size and number of pieces requirement as items
1 and 2, hence, no additional computations are
required. Thus the listings of items for 3 and 4 (for
d. The completed take-off list for the scrub
columns 6, 7, and 8) are the same as for items 1 and
