Its not that Dave Nigbor doesn’t like people. He just
prefers to not incur employee related manufacturing costs that could be reduced
or eliminated with the integration of computer-driven product costing and
production software systems into his Milwaukee area company.
But who can blame him. Cutting costs is a
primary key to success in any industry sector.
Nigbor is president of Lannon Millwork, a 20
year-old architectural casework manufacturing firm specializing in custom
institutional and commercial interiors. From his beginnings as a small
residential cabinetmaker to his current status as a major regional
manufacturer of laminate casegoods, Nigbor has strived to be a lower cost
producer, with a strong dependence on high tech machinery systems and software.
“Eight or ten years ago I had more employees
than I do now, even though I was doing a lot less business,” Nigbor explains.
“Now, with the addition of computer-linked panel processing equipment and other
pieces of extremely efficient machines, we’ve significantly reduced labor
costs, while at the same time improving overall volume and delivery.”
But he says you first have to correctly
identify your costs before you can actually reduce them. That’s where a new
cost estimating and inventory management software package, called takeoffä from
People Logic Software Corp., plays a major role at Lannon Miliwork.
Nigbor explains: “We had been using an
extremely time-consuming spreadsheet system of determining costs and pricing
jobs on a per box basis. Plus it was not as accurate and consistent as we would
have liked and we weren’t handling our raw materials inventory in the most
efficient manner. Added to that, overtime on certain jobs was too high,
particularly on the extremely custom jobs.”
Now, after just one year of using Take Off,
Nigbor says he’s generating bids 20-25 percent faster, and he’s more accurately
estimating all costs and, most importantly, margins. In addition, overtime has
been reduced and raw materials inventory is under control.
Assigning cost values
What Take Off does is
bring together multiple components of a job, from labor and materials pricing,
to scheduling and ordering. It can integrate seamlessly with the major
software packages like Pattern Systems, as well as optimizing software like
Holzma’s Cut-Rite
Currently, Lannon is
linking Take Off with Pattern Systems software. He is also utilizing a barcode
system which links a Holzma HPP 11 CNC panel saw with a Weeke BP12
point-to-point machine. Edgebanding is handled with a Brandt KD99 single-sided
edgebander.
Ninety-five percent of
product is constructed out of particleboard. Assembly is dowel construction
using a Ritter case clamp.
Take Off was developed
by woodworkers for wood-workers. It takes a parametric library approach to estimating.
Unlike most spreadsheet or database approaches to estimating where you are
required to define prices for each different size of a product, takeoffä enables
users to define products a single time, with virtual dimensions, and specify
precise dimensions at “take off time.
‘With this approach,’
Nigbor says, ‘we’re able to get accurate material requirements even if the size
for every item on the project is different. Plus, add-ons like reception desks
and curves are no problem because we can customize any product.”
With Take Off,
materials are assigned to specific groups. For example, materials used for the
construction, finish and hardware of a product can be defined in one or more
groups. This gives the user the ability to quickly do “what if scenarios with
different product combinations and see what the cost differences would be for a
particular project.

At the head of the manufacturing scheme at
Lannon Miliwork is a new Holzma HPP1 1 GNC panel saw which generates a barcode
label with all manufacturing information included.
Labor, material tracking
As mentioned earlier, custom product options
don’t pose a problem. At the product level, there is often a variable which can
be defined as “options.” The user can define separate library items for a base
cabinet, for example, with one, two or three shelves.
By defining adjustable shelves as a product
option, you again only need to have one library item with an option for the
number of shelves required for the cabinets.
The new software also generates precise labor
and material requirements for a project. Because of the exactness of the parametric
approach and the opportunity to define material waste factors, it’s possible to
determine the exact labor and material requirements at the time the estimate is
completed.
Up front, the system generates a labor table,
a total labor summary, and a total materials summary for each job, each giving
unit costs and total costs. Labor can be broken down into sub-categories for
shop labor, site labor, installation labor and separate values for shop
processes labor which can include tasks like handling, assembly cutting,
edgebanding, machining, etc.
Normally companies need to wait until a
project has been engineered before they can start planning their purchasing
and production. This creates scheduling issues that could be avoided.
“This feature is particularly important when
were ordering sheets of high pressure laminate, Nigbor explains. “If we order
ten or 20 sheets too many of a specific color or design, then we’re
inventorying some costly material that we may not use for quite some time.”
Relative to labor estimating and scheduling,
he says a benchmark labor value is taken off the edgebander. This helps get a
better handle on work flow and allows workers to be assigned where the work
is.
“Probably the most time-consuming process
happens on the front end when you’re loading your libraries,” Nigbor says. “But
after that’s done it’s just a matter of accessing the right files:’
He says the learning curve for Take Off was
one to two weeks.
“It was really quite easy to learn,’ he says. “But we’ve been moving in this direction for a long time and we were ready”
