Value engineering
frequently endangers American education. This claim may seem
far-fetched, but a strong argument can be made that many common
value engineering decisions have harmful effects on school
building quality that also adversely impact our childrens
learning experience.
These days, the term "value
engineering" often seems a misnomer when applied to school
construction projects. Value engineering is supposed to identify
a decision making process where the owner and the design/construction
team controls costs while maintaining the buildings
long-term value. Unfortunately, construction managers frequently
present value engineering choices that shorten school buildings
life spans, lead to a higher incidence of building component
failure and have a negative impact on education.
We, as school designers, repeatedly
witness some value engineering decisions that we prefer to
call mistakes. They include discarding central air conditioning
systems in favor of unit ventilators in each classroom. Not
only does this lead to shorter equipment life and higher maintenance
costs (breakdowns are common and each unit must be separately
serviced), but unit ventilators are noisy and can seriously
degrade classroom acoustics.
The acoustical environment is a
frequent victim of value engineering. Special acoustical treatments,
such as sound-absorbing concrete block specified for a gym,
often are canceled as part of a cost-cutting agenda. The result
is a din that makes it harder for schoolchildren in nearby
learning spaces to hear what their teachers are saying.
Value engineering also affects
childrens eyes as well as their ears. Standard recessed
lighting fixtures often are substituted for pendant fixtures
that provide indirect lighting. The downlight fluorescent
fixtures are cheaper but cause glare, impeding students
ability to read computer screens and significantly reducing
the legibility of increasingly popular whiteboards.
Too often, owners do not consider
the long-term, life cycle detriment of their value engineering
choices. Concrete block interior walls commonly are replaced
with damage-prone drywall and low-quality paints are substituted
for more durable epoxy paints. Decisions like these all but
guarantee higher maintenance costs. And when maintenance dollars
are tight, the substituted materials and finishes may deteriorate
even more quickly, further compromising the school environment.
Responding to complex project needs
with a rational yet spirited design is a real challenge for
any architect. Slashing costs without maintaining quality
is easy and requires little imagination. Yet, for some CMs,
the guiding principle seems to be that whatever can be removed
from the design should be removed. Canopies meant to provide
weather protection for children traveling to and from buses?
Gone. Sunscreens that reduce interior heat loads and decrease
glare inside classrooms? Forget about it.

Granted, these cuts do save money
and the CM often is hailed as a hero by the local school building
committee. Because they are usually opposed to sacrificing
even a square foot of program space, building committees and
boards of education are happy to hear about any other way
to reduce initial costs.
But all too often, CMs do not help
architects fully describe the downside of these choices, which
usually are made so late in the design process that there
is no time to debate the pros and cons. We think this approach
is irresponsible, not just to decision makers but to kids
and their education.

CMs should not be at odds with
school designers on these issues. Architects who create public
school buildings are well aware of the overriding importance
of cost in new school construction. We do not seek to produce
opulent "Taj Mahals," but within budget limits try
to design high-quality, durable and expressive buildings that
will serve a community for years. At the very least, CMs owe
their clients a thorough explanation of the repercussions
of their value engineering recommendations.
