| Why does
the Bill of Materials report have two different quantities
for each item?
In the Bill of Materials reports, Goldenseal cost
estimating software shows both a gross amount and a net amount
for each material. You'll need to use your judgement
to decide which quantity to use. It depends
on the material, and the details of the
project.
Gross Amount The
gross amount
is the amount without any waste factor. It is the "theoretical"
quantity of material you will use if there are no mistakes,
and no cutting loss.
When purchasing, order the gross amount in any of the
following cases:
- For windows, doors, fixtures and other "singular" items. NOTE-- the
waste factor covers disasters that may happen, but
you don't know which items will have those problems,
in advance!
- When it is easy to get more materials without causing
delays, and when you don't have to worry about color
matching or other problems caused by multiple batches.
- When it's a small job, and you think you'll probably be
careful.
- When it is difficult or impossible to return overstock.
When purchasing, order less than the gross amount in
any of the following cases:
- When you are "trying out" a material and
may change to something else, later.
- When there is no room to store all of the
material.
- When the material will be used over a long
time period.
Net Amount
The net amount is equal to the gross amount, plus the
calculated waste factor (from the Assembly record). It
is the "typical" quantity of material that you will
use, averaged over time. Some projects will probably need
a little more than
the net amount, while some will need
less.
When purchasing, order the net amount in
any of the following cases:
- For windows, doors, fixtures and other "singular" items
on very large projects, when you are ordering hundreds
of items, and can use the items somewhere else if
the waste is lower than expected.
- When it is difficult to get more materials,
without causing delays.
- When deliveries are difficult because of distant location or
other problems.
- When it is easy to return
any overstock.
When purchasing, order a little more than the net
amount in any of the following cases:
- When it is extremely difficult to get more
materials, without causing delays.
- When project dimensions or other conditions
will cause more trim loss than usual.
- When you have
to worry about color matching or other
problems caused by multiple batches.
- When deliveries are very difficult
because of distant location or other problems.
- When it is very easy to return overstock.
