Division Learns More About BIM During GANA Fall Meeting
Once you go BIM, you'll never go back. So was the caution from
Will Ikerd, II, P.E., C.W.I., gave a presentation on building information
modeling (BIM) at the Glass Association of North America (GANA's)
Fall Conference here in Dallas.
Ikerd presented an overview of the system (CLICK

instance, "Industries that change to this type of modeling
never go back," he said, citing the automotive and aerospace

discuss BIM at the Building Envelope Contractors meeting during
GANA's Fall Conference.
He also noted, "This BIM adoption will happen faster than
many will realize."
While many presentations given in the last several months have
provided overviews of the system, Ikerd spoke specifically to the
role the contractors sitting in the room would play in design-construct
teams using BIM.
According to Ikerd, "When someone's talking about BIM you
need to know their perspective of where they're coming from."
Specifically, know which of the various databases the other party
is referring to as there are systems that hold information on fabrication,
dimensional control, value engineering, clash detection and other
Ikerd also noted that BIM changes the working relationships among
the individuals involved on a given project, since no one really
owns the project model to which each group-architects, owners, general
contractor and subcontractors-each contribute. As a result, subcontractors
are often brought into the process earlier than in traditional projects
to contribute their knowledge to the model. "Instead of viewing
[glazing contractors] as subcontractors you start viewing them as
'specialty contractors,'" Ikerd said.
Since these projects become much more collaborative in nature,
one of the questions surrounding BIM is the matter of ownership.
According to Ikerd, unique situations have arisen where the architect,
owner and contractors essentially become a single entity through
the collaboration, and even indemnifying one another for the work
within the tri-party agreement. According to Ikerd, that can pose
potential problems for subcontractors and sub-consultants who remain
on the outside of the agreement. As Ikerd pointed out, "It
won't be for all buildings, it won't be for all owners." But
for those special situations, a glazing contractor may have little
recourse should a problem arise.
Ikerd also noted that BIM is becoming more involved in code and
standard setting organizations. For example, touching on the topic
of energy, much discussed at the Fall Conference, Ikerd noted that
"as BIM emerges more, it will go hand in hand with LEED."
He also explained that the International Code Council (ICC) has
used BIM to automatically check for code compliance through the
SMARTcodes. According to ICC, "a SMARTcode is the provisions
of any code in an interoperable format that provides a rule set
from or limitations based on criteria in the code that can be used
by model checking software to identify items in a design represented
by a building information model that are outside the bounds established
by the code."
The GANA Fall Conference continues today with meetings of the Tempering,
Insulating, Mirror and Decorative Divisions.
