Constructor - January/February 2018 - 40

Gilbane shares a financial incentive with subcontractors participating in its
BIM safety program, which requires planning and working through sequences.

Brasfield & Gorrie also creates
3D-crane models to try different scenarios
until the team finds the best crane locations, clearances and sizes for the safety
of the site and surroundings.
"Once we have created models, we are
starting to put them into a virtual reality platform to have our field team do a
virtual site-specific safety and constructability walk," Hayter says. "By virtually
walking through the site as if it were
complete, safety managers, superintendents and other field personnel can start
to recognize possible safety issues and
discuss how to best prepare for them."

DESIGNING FOR SAFETY
Specialty contractor Southland
Industries has adopted Safety Through
Design, a "concept of mitigating occupational hazards by designing them out,"

according to Dunn. "We believe hazards
and risks are more effectively and economically addressed by this process. It
gives us an opportunity to walk a job
virtually."
Dunn considers preventing falls a key
opportunity when using modeling, which
can identify leading edges, access and
egress points, openings and skylights,
elevator shafts, loading zones and other
hazards. Southland has implemented
cast-in-place fall protection. Dunn notes
on the model places for anchors in the
ceiling during the decking phase, before
the concrete goes in.
"It eliminates the burden of drilling
overhead for hangers or safety supports,"
he says.
Southland also models excavations to
determine trench protection, depth and
location of underground utilities when

excavating. It also models crane plans
and confined spaces.
"It enables us to plan better," says
Brandon Zeleniak, division BIM and constructability leader at Southland.

MAKING SAFETY A PART OF
EVERY JOB
"Safety is something we cannot do
by ourselves," Myers says. "We do it in
a way that subcontractors participate in
the process. And we get better buy-in
from the subs."
Gilbane shares a financial incentive with subcontractors participating in its BIM safety program, which
requires planning and working through
sequences.
"Unsafe activities happen when we
try to do work that is above our risk
tolerance," Myers says. "To keep things
operating to a risk tolerance we are
happy with, we make people model and
produce application drawings."
Gilbane requires subcontractors
to take the design model and create
a detailed model and shop drawings.
Then the subcontractor's foreman must
develop a safety task assessment and a
job hazard analysis, which are reviewed
by Gilbane. Myers says it empowers the
field foreman with safety and efficiency
responsibilities.
"The model becomes a communication tool," he says. "The more information you have the better off you are.
Modeling makes the process more accurate and quicker."
Much of the work takes place in a
workshop, as teams prefabricate components in a climate-controlled environment on a bench top. Those components
are hauled to the jobsite and put in place.
He said the technology has evolved to
make it happen. Going forward even
more buildings will be constructed using
modeling and prefabrication.
"The future is bright; we just have
to get there," Myers says. "We want to
light the way there with our current
practices."
