Maximizing the
Value of BIM
By Bradley Schulz, M.SAME
Compared to legacy
technologies, BIM enables
government projects
throughout the entire building
lifecycle to be completed
faster, greener and less
expensively.
Design & Construction
I
ncreasingly, government agencies
are embracing building information
modeling (BIM) lifecycle capabilities
for the same reasons private industry
has: to improve communication among
stakeholders, maximize ef?ciency, cut
costs during design, construction, op-
erations and maintenance, and analyze
and implement sustainability features.
The General Services Administra-
tion (GSA) was among the ?rst to real-
ize BIM could help government achieve
ef?ciency and cost savings. Since then,
GSA has led the charge for BIM in gov-
ernment, helping jumpstart adoption
of the process and technology in 2003,
when the agency established the Na-
tional 3D-4D BIM Program. The de?n-
ing moment for BIM in government,
however, may have come in 2007, when
the GSA began requiring that all pro-
spectus-level projects use a BIM model
for ?nal concept approvals. Today, mili-
tary engineering organizations also are
more widely adopting and deploying
BIM processes and 3D technologies
and enjoying their bene?ts.
Complex Requirements
Federal buildings must meet func-
tional needs—such as sound isolation,
venting and blast protection as well as
program requirements for information
technology, square footage and opera-
tional tools—at a much higher level of
speci?city than is common in the com-
mercial buildings market. Thus, military
engineers have even more to gain from
leveraging BIM in early planning.
Collecting all the requirements
of a facility in a database early helps
ensure data currency, said Marwan
Bakri, HNTB BIM Technology Manager.
Rather than depending on individually-
collected information input by hand,
data on building requirements are
managed, organized, stored and
formatted so data loaded for planning
can be easily transferred into the BIM
model during design.
In the past, blocking and stacking
models worked to ?nd the ?rst de-
sign that ?t requirements. Today, BIM
processes and 3D technology found in
software applications such as Autodesk

BIM renderings, such as this one of the Human
Resource Center of Excellence facility at Fort
Knox, Ky., integrate data on structural elements,
utilities and other systems to help avoid clashes
and lengthy cost and time overruns during
construction.</p>
