Is There Real Value in Value Engineering
?
Can value engineering really increase value or save money
on a construction project? Does it actually reduce unnecessary
costs or does it simply substitute cheaper materials and methods
for more costly ones?
At times, questions like these have sharply divided the industry
While value engineering can be misused, the real question
should focus on how it can be employed to the project's greatest
advantage.
Definitely, Say Some
Architect Steven J. Kirk, a vice president of Smith, Hinchman
& Gryllis Associates in Detroit, and a board member of
SAVE (Society of American Value Engineers), sees no conflict
between good design and value engineering.
kirk says, "we define what the objectives of a client are
in our value engineering study and if one of those functions
is historical, architectural or aesthetic character, then
that is the 'given'. those values won't be sacrificed. rather,
the savings would come from other areas, like finding the
best life cycle mechanical systems."
He maintains that, if used properly, value engineering can
save between 10 and 30 percent of the initial construction
cost and significantly reduce life cycle costs.
Not Necessarily, Say Others
Not everyone would agree. Some see value engineering as merely
a euphemism. For them, "value" simply means lower
cost while "engineering" implies a level of expertise
that's often not provided, since value engineers are not required
to be actual engineers.
Judy Selwyn, principal of Preservation Technology Associates
in Boston, says she almost regards value engineering as "a
dirty word." She says, "It almost implies that there's
a cheaper way to get the job done than the way the designer
designed it."
Selwyn cites as an example a $20 million government renovation
project in which value engineers had the upper hand without
the designers even being consulted.
The designers recommended that certain columns be replaced
either with cast iron or a similar material, such as aluminum.
Such a choice would emulate the physical and aesthetic characteristics
of the original design closely enough as to make the change
inconspicuous.
"Instead, wood was used," says Selwyn, as recommended
by the value engineers. This was a poor choice in her judgment
since wood has neither the look nor the feel of the original
material, and wood joints also tend to open up over time.
On another project, Selwyn explains that value engineers functioned
like a shadow team. Conferences were kept separate from the
design process, preventing the designer from defending his
ideas and instead making them subject to change by non-designers.
Three Key Words Make All the Difference
What separates the views represented by Kirk and Selwyn is
perhaps best expressed in Kirk's qualifier: "if
used properly
" Value engineering must
be a joint effort.
Sometimes there may be a tendency not to fully explore available
materials and methods. Often there are alternatives available
which are not well known but are more than adequate and less
costly. Different points of view can help identify a greater
range of viable options.
It's also crucial to understand that much more is involved
than the apparent cost of one alternative over another. For
example, the cost of a waterproof coating must be weighed
against its volatile organic compounds (VOC) compliance and
whether it calls for special respiratory equipment for workers,
or other requirements to protect the public. Measured by its
cost per gallon, one product may be cheaper than another,
but overlooking its associated costs can be counterproductive
Operating costs must also be evaluated. Materials, methods
and systems that reduce maintenance expenses should not be
sacrificed just to decrease construction costs. Initial savings
can often come back as a larger cost in the long run.
Our Point of View
- Value engineering decisions should be part of an interactive
process involving all members of the construction team.
It should be ongoing throughout the design and should involve
the architect/engineer, construction specialists and the
project owner.
- Value engineering must consider constructability and contractability
as well as building materials and systems. The sequence
of installation, weather conditions, and time requirements
involve more than can be revealed in data or spec sheets.
The addition of other trades or subcontractors may have
significant cost impacts, either favorable or unfavorable,
when measured in the short and long term.
- Value engineering should define all the objectives of
a project, including historic, architectural and aesthetic
character, and it should respect these elements in harmony
with efficiency and quality
- Value engineering must include life cycle costing to properly
match the materials, methods and installed equipment with
the planned useful life of the building. The consideration
given to alternate materials and equipment under a life
cycle approach will contribute significantly to the impact
of all cost-vs.-quality decisions made by the project team.
For example, if project funds are tight, long-term savings
may be secondary to getting the project off the ground. Thus,
a very efficient HVAC system may have to be sacrificed for
a smaller, less efficient system, one that may even cost more
over time. Without certain tradeoffs, some projects would
never be completed. All such decisions should be made with
complete information and consideration of alternatives.
Confrontations over value engineering can arise when the designer
feels compromised. The real value in value engineering can
only be realized when the project team members are all committed
to the same common goal.
