This class covers the use of Autodesk Revit Structure software in a workflow designed to share the engineer’s model directly with a fabricator for downstream use. Being able to take models to the next level by using them in a digital review process is a natural step, and this class shows how paper-based shop drawing review can be minimized, if not altogether eliminated. We present a case study describing how a digital shop model approval process was used in lieu of the traditional paper shop drawing process along with the value experienced for the project. This class also touches on best practices and limitations and shows attendees how to create a checklist that enables a project to use models as part of the shop drawing review process.
Class Summary
#AU2013 #johannpalacios #allthingsVDC
At the end of this class, you will be able to:
Describe best practices for sharing models produced in Revit with downstream users
Prepare checklists that are critical to a streamlined shop model approval process.
Identify and describe the limitations of a digital shop model review process and how to address them.
Create a workflow using Autodesk Revit along with third-party communication programs.

Review – Using GTM, weekly
Tracking – Using MS Onenote
Approvals – Using Tekla models
Case Study: Dillard University PSSB
#AU2013 #johannpalacios #allthingsVDC
- Instant understanding of the issue - Saved 6 weeks off of the schedule- No field changes due to design
review- Increases quality and value of the
process
Case Study: Dillard University PSSB
#AU2013 #johannpalacios #allthingsVDC
- Have a structural game plan that focuses on fabricator’s and steel erector’s practice
- Consider connections!- Involve the fabricator and steel erector
from the beginning of the design (design build model)
- Assign the task of coordination software versions to both the fabricator and the engineer as early as possible
Case Study: Dillard University PSSB
#AU2013 #johannpalacios #allthingsVDC
- Take into account the experience level of the team members
- Develop checklists!- Have a proactive mindset- Encourage managed risk
taking- Address culture if needed

BIM relies upon collaboration Fast-Track Nowadays there isn’t a project in NYC that
isn’t fast-tracked Impossible to meet schedule constraints
without it Because we can…..to a certain
degree… depending upon where you are.

New York State Case Study
#AU2013 #johannpalacios #allthingsVDC
Located in Westchester County Scheduled Completion – May 2015 Approximately 45,000 SF, 6-story addition
including 4 state-of-the-art OR’s and approximately 30 new patient rooms.
Phase II of a 10-Year Master Plan, that once complete, will make this one of the largest Hospitals in Westchester County.

Lessons Learned/Benefits- Adapt to Issues @ Hand- Could not completely eliminate shop drawing
submission b/c DOB requires stamped drawings showing erection plans, connection details achieve the design criteria defined in the basis of design and CD’s. i.e. It’s State Legislation
- Saved 4 weeks of Schedule
