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


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



- 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



- 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



- 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


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.
