SUBMITTAL TRACKING<br />
THE PROBLEM<br />
•24 steel sequences<br />
• Overlap of original<br />
submittal, resubmittal,<br />
and fabrication processes<br />
• Partial approval of each<br />
sequence<br />
THE SOLUTION<br />
• Track submittal status<br />
of each piece of steel<br />
• Import submittal log<br />
into model<br />
<strong>South</strong> <strong>Lawn</strong> Overview<br />
THE RESULT<br />
• Color coded model helped<br />
prioritize and focus submittal<br />
review efforts.<br />
• Submittal review and<br />
fabrication condensed.
MATERIAL STATUS<br />
CONNECTION STATUS<br />
THE PROBLEM<br />
• 174 connections had<br />
inspection problems<br />
• Additional work was<br />
needed before slab pour<br />
could occur<br />
THE SOLUTION<br />
• Create user defined<br />
attributes to track<br />
connection problems<br />
• Utilize color coded<br />
model to evaluate slab<br />
pour status<br />

THE RESULTS<br />
• Magnitude of problems<br />
were quickly understood<br />
through model and<br />
reports<br />
• Slab pours proceeded<br />
as scheduled<br />
• Communicate critical sequences better<br />
• Utilize only in select areas<br />

RESULTS<br />
RESULTS<br />
• Better & quicker understanding of information is the main time &<br />
money saver<br />
• <strong>BIM</strong> can adapt to tackle new project specific problems, planned or<br />
unplanned<br />
KEYS TO RESULTS<br />
• Flexible, user-customizable technology<br />
• Ability to tackle different problems with the same basic process<br />
• Integration with multiple parties at differing abilities<br />

PRECAST STATUS<br />
THE PROBLEM<br />
• 1300 pieces of precast<br />
needed to be delivered to<br />
the mason<br />
• Masonry sequence was<br />
revised during precast<br />
production<br />

• Review if correct pieces were<br />
delivered; provide list of<br />
needed pieces<br />

DISCLAIMER<br />
THE RESULTS<br />
• Missed pieces were quickly<br />
delivered<br />
• Precast delivery remained<br />
flexible to changing sequence<br />
The process for defining <strong>BIM</strong> value is<br />
very subjective.<br />
Would this<br />
problem have<br />
been found<br />
without <strong>BIM</strong>?<br />
Who would have<br />
had to pay for<br />
this problem?<br />
What would have<br />
been the costs if<br />
we hadn’t found<br />
this problem?<br />
If we’re under budget or ahead<br />
of schedule is that because of<br />
<strong>BIM</strong> or something else?<br />
