Estimating with the Five-Part Judgement
Analysis, Part II
In this second part of a two-part series (see Estimating
with Five-Part Judgment Analysis, Part I, May 2007), we
explore how project analysis and company capabilities affect estimating
for remodeling and renovation projects. We have also included a really
great free download,
Calculating the Impact of Judgment Factors worksheet, to help
you track the impact of your judgment factors for your jobs.
Project Analysis
Whether you are considering a remodeling or renovation project, chances
are you will be working with an existing structure or footprint. Often
you will need to "tie-in" the remodel or renovation work to what is
already there. You need to look carefully at:
- existing
materials (millwork, brick, roofing, windows, siding, doors),
- roof
lines,
- foundation,
- heating,
- electrical,
- floors
and
- heating
and cooling systems.
Your estimates should include specifications that
protect you from having to do an exact match on existing materials.
Reviewing existing materials and using your judgment as to how
difficult it might be to match as closely as possible the existing
materials, however, is an important aspect of estimating. No homeowner
will want to see a substantial difference in roof color from an
existing structure to an addition. Homeowners will want to see matching
— or complimentary — windows, doors, millwork,
flooring, etc. You need to employ your judgment, and
maybe incorporate some research, as to how difficult matching existing
materials will be. Is the millwork special order? Do
you need to level the existing floor to match a new one? You should
factor into your estimate how much of an impact, cost-wise, matching
existing materials will be.
Company Capabilities
You have been running your business for some time — and only
you know best what your company is capable of doing. You know your
team’s strengths and weaknesses. You know how long a certain
project typically takes to complete. You know your sub-contractors,
their capabilities and how they perform for you. All of these factors
need to be reviewed during the estimating process. Why? Because a shift
in any of these areas can drastically affect the profitability of the
work that you do.
What happens if you typically work with a certain
plumber and that plumber is tied up on a job or, you need more
resources than that plumber is able to provide? You need to factor in
additional costs for using a plumber or plumbers who are not as
familiar to you. You may not receive comparable rates from the new
plumber, or you may find that the new plumber does not work as
effectively as your primary plumber. There is typically a learning
curve with each new subcontractor you hire and if you know at the onset
of a project that hiring a new subcontractor will be required, your
estimate should reflect these higher costs.
Is your company capable of taking on more work?
Understanding your existing job commitments and how a new project could
factor into this workload can affect how you estimate a job. If your
crew’s time is already allocated, and you want to take on
more work, hiring new people and supervisory staff to manage the job
can have a huge impact on what you should charge for a job. Likewise,
if your workload is on the lighter side, you might choose to lower your
profit in order to win projects. Consider carefully whether the
additional work is worth the decrease in profit.
Are you quoting on a job that is mostly labor or
mostly materials? You should be aware of your mix of labor vs.
materials since these two components will affect your overall
profitability. A job that is unusually labor-intensive
should be marked up at a higher rate, because the standard ratios of
mark-up and margin are based on roughly equal percentages of labor,
materials and subcontractors. Recently, more
contractors are marking up labor 125% and materials 25% rather than
marking up each of them the historical 50%. On an average job roughly
evenly divided between materials and labor, these markups should
generate a gross profit of 40-43%.
On the other hand, if a job is almost completely
subcontracted, and materials are also a high proportion of job costs,
the profit margin might safely be somewhat lowered. Do not make the
mistake of dramatically lowering the margin, however, because you know
you have to stand behind the work of the subcontractors and you'd
better protect yourself in the estimate.
In estimating remodeling and renovation projects
— experience counts. Being able to use your judgment on a
variety of factors can substantially affect your profit margins.
