EVEN BETTER TOGETHER: Collaboration between Architects and Structural Engineers in Revit

1. EVEN BETTER TOGETHER:Collaboration between Architects and Structural Engineers in Revit Irina Wong

2. ABOUT THE SPEAKER I’m an expat architect who is now the BIM Coordinator at Degenkolb Engineers, a structural engineering firm in Washington, Oregon, and California. My roles include coordinating Revit projects across disciplines, managing the firm’s BIM practice, maintaining responsibility for company-wide best practices, providing technical support, and leading the development of the firm’s future BIM direction. In short, I plan models, I build models, fix models, and, more often than I will care to admit, crash models.

3. LEARNING OBJECTIVES Make informed decisions at project startup and maintain strong communication through completion. Improve your workflow by understanding the perspectives and expectations of other disciplines. Develop a Building Information Model that implements proper Revit techniques for improved design coordination.

4. RULES OF THE ROUNDTABLE Share your experiences! Everyone is likely to have diverse experiences and unique lessons learned. Kindly respect the differences. I have an egg timer and I’m not afraid to use it.

14. THE BIM KICKOFF MEETING What? • Articulate model expectations • AIA E202 BIM Protocol Exhibit LOD300 Model Content: attributes and parameters defined by the owner. Purpose: Estimating, construction coordination for clash detection, scheduling, and visualization. LOD100 Model Content: overall building massing Purpose: Whole building analysis including volume, building orientation, and SF costs. LOD400 Model Content: fabrication-ready detail. Purpose: construction and fabrication of project components, including MEP systems. LOD500 Model Content: Central data storage of project, including completed parameters and attributes. Purpose: Building maintenance and operations systems. LOD200 Model Content: approximate quantities, size, shape, location and orientation.   Purpose: analysis of defined systems and general performance objectives.

16. THE BIM KICKOFF MEETING What? • Articulate model expectations • Custom in-house Level of Development Matrix PROJECT MILESTONES 8. Floor framing 11. Braces 13. Gusset plates 14. Column base plates MODEL ELEMENTS

17. THE BIM KICKOFF MEETING What? • Articulate model expectations • Custom in-house Level of Development Matrix None: Info is not part of scope. C/M: Info will be represented in our model & drawings, but it will be only copy/monitored from the architect. Notes: Info will be represented in General Notes and other written forms of communication. 2D drawings: Info will be drafted in 2D drawings, details, and annotations; may be supplemented by notes. Parametric: Info will exist in the parametric values of 3D objects, but will not be modeled. 3D: Info will be modeled in 3D; may be supplemented by 2D drawings and notes.

18. THE BIM KICKOFF MEETING What? • Articulate model expectations • Custom in-house Level of Development Matrix 1. FYI 2. For coordination 3. For construction 4. Fabrication 5. Record drawings

19. THE BIM KICKOFF MEETING WHAT? • Articulate model expectations • Custom in-house Level of Development Matrix

20. THE BIM KICKOFF MEETING WHAT? • Establish collaboration procedure • Designate Revit origin, coordinates, elevation • Set the model-sharing timeline • Refrain from “throwing the model over the fence” • Decide upon milestone coordination meetings

21. THE BIM KICKOFF MEETING What? • Determine post-design procedure • Discuss BIM’s role in the CA process • Clarify As-Built or Record Drawing requirements

22. what’s your perspective on coordination techniques and issues at project kickoff?

23. THE ARCHITECT’S USE OF THE MODEL

24. THE ARCHITECTS’ USE OF THE MODEL The Revit Architecture Environment (aka the BDS 2013 “Architecture” Tab) • The tab contains commonly-used architectural elements. • Some components (“Wall” and “Floor”) are named alike in Structure and Architecture. • “Architecture” is non-loadbearing • “Structure” is loadbearing

25. COORDINATION AND CLASH DETECTION • 3D views • Section boxes • Visibility/Graphics modifications THE ARCHITECTS’ USE OF THE MODEL

26. PRODUCTION • Presentation materials • Construction Documents • 2D and 3D views THE ARCHITECTS’ USE OF THE MODEL

27. for the architects in the room – how do you use the model?

28. THE STRUCTURAL ENGINEER’S USE OF THE MODEL

29. THE SE’S USE OF THE MODEL THE REVIT STRUCTURE ENVIRONMENT(AKA THE “STRUCTURE” TAB IN BDS 2013) The tab contains structural elements.

30. MODELING: THE STRUCTURAL ENGINEERS’ PERSPECTIVE MODEL CATEGORIES: A FEW ITEMS OF NOTE • Structural Framing X X

31. MODELING: THE STRUCTURAL ENGINEERS’ PERSPECTIVE MODEL CATEGORIES: A FEW ITEMS OF NOTE • No “roofs”

32. STRUCTURAL ENGINEERS’ MODELING ANALYTICAL MODEL • It‘s a simplified 3D representation of the full engineering description of a structural physical model.

33. STRUCTURAL ENGINEERS’ MODELING COORDINATION AND CLASH DETECTION • We turn off everything in the architect’s model but: • Walls • Floors and floor openings • Roofs • Grids/Levels • Then, we look at the updates that affect our design.

34. THE SE’S USE OF THE MODEL COORDINATION AND CLASH DETECTION - CHALLENGES • Copy/Monitor • “Elements deleted?! But I seethe grids. Why does it say they’re deleted?”

35. THE SE’S USE OF THE MODEL COORDINATION AND CLASH DETECTION - CHALLENGES • Roof slopes (or anything sloped)

36. for the SEs in the room – how do you use the model?

37. TIPS FOR THE STRUCTURAL ENGINEERS

38. TIPS FOR THE SEs CHECK YOUR WORK IN 3D. • … well, not really. • Looks about right…

39. TIPS FOR THE SEs THE CLIENT MIGHT WANT PRETTY PICTURES. • Structural Model • Finished Rendering

40. what tips do you have for the SEs in the room?

41. TIPS FOR THE ARCHITECTS

42. TIPS FOR THE ARCHITECTS REMEMBER THE DECISIONS MADE DURING THE BIM KICKOFF MEETING • Level of Development agreements • Collaboration procedures • Origin • Coordinates • Sectors • North • Elevation Datum • Etc.

43. TIPS FOR THE ARCHITECTS COLLABORATION PROCEDURES: THE ORIGIN POINT • Where is it geographically? • Use Shared Coordinates or Internal Origin? PROJECT BASE POINT • Specific to each file • “Origin-to-Origin” SURVEY POINT • Once Acquired or Published, it becomes the “Shared Coordinate”

44. TIPS FOR THE ARCHITECTS MAINTAIN THE DECISIONS MADE DURING THE BIM KICKOFF MEETING • Keep the origin, datum, sectors, and north • Modify Copy/Monitored elements – don’t delete. • Remember the LOD agreements MODEL WELL • Maintain clean dimensions • Use logical tools for modeling

45. what tips do you have for the architects in the room?
