BIM and Collaboration
@PESengineers
Two or more people working together towards shared goals
#BIMForumED
What can we do?
@PESengineers
Utilize structural expertise, project knowledge and BIM capabilities to assist construction teams
#BIMForumED
The Process
@PESengineers
• 3 Primary Phases
• Phase 1 – General Model
• Phase 2 – Framing Model
• Phase 3 – Documentation
#BIMForumED
General Building
@PESengineers
• Phase I model identifies coordination gaps not uncovered during 2D drawing development
#BIMForumED
Framing Model
@PESengineers
• Phase II model focuses on repetitive members to flush out conflicts

Case Study #1
@PESengineers
Multi‐Family Project• 4‐story wood framing on partial podium • Apartments wrap parking deck• Level misalignment between wood framing and precast parking deck• Edge of slab dimensional bust
#BIMForumED
Case Study #2
@PESengineers
Multi‐Family Project • 5‐story wood framing on transfer podium • Dimensions in unit plans inconsistently reference f/stud and f/finish wall • Resulted in large discrepancies in overall dimensions
#BIMForumED
Case Study #3
@PESengineers
Hospitality• 4 stories wood framing• discrepancies between architectural grid and structural grid dimensions. • Slab poured using structural grids and steel fabricated using the architectural grids.
#BIMForumED
Case Study #4
@PESengineers
Hospitality • 4 stories wood framing over underground parking• Post‐tension transfer podium• MEP penetrations were modeled and coordinated with all of the PT, then the
penetration locations were provided to the surveyor for accurate locations. • Geofoam modeling and detailing using dynamo
#BIMForumED
Case Study #5
@PESengineers
Hospitality • 4‐story wood framing with steel framed amenity space• Bottom of steel coordination with prefab wood wall panels• Space in plenum for ductwork

Roundtable Discussion
@PESengineers
Do you feel that you are blurring the line on scope when collaborating effectively?
#BIMForumED
Roundtable Discussion
@PESengineers
Will the master builder role make a resurgence or are problems of today far too complex for one person to be able to solve?
#BIMForumED
Roundtable Discussion
@PESengineers
Is the industry‐wide approach to limit scope in an effort to minimize liability as beneficial as intended?
#BIMForumED
Roundtable Discussion
@PESengineers
Should designers always defer means and methods to contractor?
