estimating staff. After all, who knows your job better
than you? Once the MTO is generated, list materials by
material type and compare it to the BM. If the BM does
not list your material, you must order it. If they do not
give you enough, you must get more. And if they gave
you too much, you must cancel the extra. The following
example should help make this concept clearer.
During your project planning you identified the
following materials needed to complete the job:
6,850 board feet (BF) of 12 foot 2X4s
420 BF of 12 foot 2X6s
Four 50 lb boxes (BX) of 16 penny nails
75 pieces of 5/8 x 4x8 wallboard
Now go back to figure 3-14 and see how much the
BM gave you. Using a BM/MTO comparison worksheet
(fig. 3-15) you can make this comparison.
We just took one activity and compared what we
think we need to what the NCR thinks we need. Did you
find all those on the BM? The bill of material line item
(BMLI) is the BM number taken from the upper
right-hand corner of the BM (GER-110) and the line
item number of your material. We found the BM
shortchanged us 342 board feet of 2X4s and 1 box of
nails. They did give us 15 extra pieces of wallboard.
Now it is time to correct these oversights.
Add-ons and reorders are two commonly
misunderstood terms. A reorder is used to order an
already existing BMLI. An add-on is used to order a
completely new line item not found on the BM.
Reorders use the same BMLI number. Add-ons use a
new item number. The easiest way to remember the
difference between the two tools is, if your material was
lost or damaged in shipment, reorder it. If you just need
more, do an add-on. You are the person who makes this
step happen. Now that the problems are identified, use
the flowchart in figure 3-16 to do the paper work.
The first step is to do add-ons for the material you
are short. Figure 3-17 has the blanks filled in for the
material not sent but still needed.
