1 Better Together: Best Collaboration Practices for Architects and Structural Engineers Using Autodesk Revit Irina Wong BIM Coordinator, Senior CAD/BIM Specialist Degenkolb Engineers Sam Schafer Architectural Designer Integrus Architecture Class Summary This class is for those who have experienced challenges when collaborating with other design disciplines using Autodesk Revit. In this class, you will discover techniques for Revit modeling, document creation, model management, and communication to facilitate the crossdiscipline project workflow. About the Speakers IRINA WONG Irina Wong is the BIM coordinator at Degenkolb Engineers, a structural engineering firm with six offices in the West Coast. Her roles include coordinating Autodesk Revit projects across disciplines, managing the firm s BIM practice, providing technical support, and leading the development of the firm s future BIM direction. SAM SCHAFER Sam Schafer is a designer at Integrus Architecture in Seattle, Washington. His involvement in implementing Revit workflow procedures, providing training workshops, and developing project coordination techniques have been key factors to the success of several projects. His role on projects focuses on daily collaboration across all design disciplines. 1

2 Learning Objectives At the end of this class, you will be able to: Make informed decisions at project startup and maintain strong communication through completion Improve your workflow by understanding the perspectives and expectations of other disciplinesi Develop a Building Information Model that implements proper Autodesk Revit techniques for improved design coordination Take advantage of Autodesk Revit tools to manipulate links, organize data, and access the information you need Session Outline BIM Philosophy BIM Project Kickoff Meeting Using the Model: The Architects Perspective Using the Model: The Structural Engineers Perspective Modeling Well: Tips for the Structural Engineers Modeling Well: Tips for the Architects Conclusions BIM Philosophy 2

A facilitator to manage the entire meeting From each discipline: Manager(s) of project Manager(s) of digital model Identify team members and roles Who will field the design questions? Who will field the BIM questions? The BIM Project Kickoff Meeting WHY? Manage expectations and goals No surprises Set timeline for workflow The BIM Project Kickoff Meeting WHAT? Articulate model usages and expectations Establish collaboration procedures Determine post-design process 5

Establish collaboration procedure Designate Autodesk Revit origin, coordinates, elevation datum, north, and sectors Set the model-sharing timeline Refrain from throwing the model over the fence Discuss verbal/graphic methods for communicating change Milestone coordination meetings The BIM Project Kickoff Meeting WHAT? Determine post-design procedure Discuss BIM s role in the CA process Clarify as-built or record drawing requirements Using the Model: The Architects Perspective 9

10 Using the Model: The Architects Perspective The Revit Architecture Environment Interface and tools Home tab: frequently used tools Structure tab: rarely used Using the Model: The Architects Perspective The Revit Architecture Environment Model In-Place components Family category affects how the element is controlled with Visibility/Graphics Using the Model: The Architects Perspective The Revit Architecture Environment Model In-Place Components Fewer element property options than a regular component standard wall in-place wall 10

11 Using the Model: The Architects Perspective Coordination and clash detection across multiple disciplines 3D views Section box View Templates Using the Model: The Architects Perspective Presentation Graphics Renderings straight from Revit Architecture Unable to edit linked model materials Copy and pasting from linked model Using the Model: The Architects Perspective Construction Documents Standard 2D views May include 3D views Clarifies design intent Requires extra attention for coordination 11

12 Using the Model: The Structural Engineers Perspective Using the Model: The Structural Engineers Perspective The Revit Structure Environment Coordination Using the Model: The Structural Engineers Perspective The Revit Structure Environment Interface and tools Home tab: frequently used tools Architect & Site tab: massing, architectural, and site tools 12

13 Using the Model: The Structural Engineers Perspective The Revit Structure Environment Model Categories x x Default beam modeling creates gap between beam and column X = Start/End Extension value Using the Model: The Structural Engineers Perspective The Revit Structure Environment Model Categories Structural reinforcement parameters available Structural Usage is Bearing Using the Model: The Structural Engineers Perspective The Revit Structure Environment Model Categories Structural reinforcement parameters available Structural Usage is Bearing Floor and Slab Foundation behave exactly the same except for the Model Categorization. No loadbearing Roof option. 13

14 Using the Model: The Structural Engineers Perspective The Revit Structure Environment Model Categories Structural Column is loadbearing and contains the other structural analysis properties. Architectural Column has none of those characteristics. Using the Model: The Structural Engineers Perspective The Revit Structure Environment Model Categories Column is an Architectural Column Structural Column is just that. Using the Model: The Structural Engineers Perspective The Revit Structure Environment Model Categories Unlike the freehand-drawn Slab Foundation, Isolated (or Spread) and Wall Footings have a set shape. They move with their associated Columns and Walls, respectively. 14

15 Using the Model: The Structural Engineers Perspective The Revit Structure Environment Analytical Model The Analytical Model is displayed as lines that represent the engineering system instead of the physical geometry. Can be turned off in Visibility/Graphics Using the Model: The Structural Engineers Perspective Coordination the process Generally, everything in the architect s model may be turned off but: Walls Floors and floor openings Roofs Grids Levels Using the Model: The Structural Engineers Perspective Coordination the challenges Roof Slopes Copy/Monitor 15

16 Modeling Well: Tips for Structural Engineers Modeling Well: Tips for Structural Engineers Work heavily in 3D Framing may look correct in plan but accidentally offset in Z-direction Exposed structural connections Level of detail Structural Architectural Modeling Well: Tips for Structural Engineers Indicate clearance required Represent geometry not modeled with model lines Improves coordination with other disciplines Rebar around wall opening Electrical devices at opening 16

17 Modeling Well: Tips for Structural Engineers Create components using correct model categories and tools Easier to manipulate in Visibility/Graphics Wall Opening tool vs. Blank Door family Blank Door family Wall Opening tool Modeling Well: Tips for the Architects Modeling Well: Tips for the Architects At the start Refer to the decisions made during the BIM Project Kickoff Meeting Model usages and expectations Level of Development agreements Collaboration procedures -- origin, coordinates, sectors, north, and elevation datum 17

18 Modeling Well: Tips for the Architects Collaboration procedures: decide on origin point Geographic location Shared Coordinates or Internal Origin? Project Base Point File-specific Origin-to-Origin Survey Point Once acquired or published, it becomes the Shared Coordinate Modeling Well: Tips for the Architects Throughout the design Keep your origin, elevation datum, sectors, and north Modify Copy/Monitored elements don t delete Maintain clean dimensions Model critical objects (refer to Level of Development agreements) in 3D no detail lines Use logical tools for modeling 18

24 Conclusions There is more to BIM than modeling within your own discipline; in fact, there is more to BIM than modeling itself. The most important coordination tool we have is the BIM Project Kickoff Meeting. Architects and Structural Engineers use the model differently respect it. Both Architects and Structural Engineers need to model accurately, logically, and to the agreed Level of Development. Autodesk Revit has many tools to manipulate visibility and pull information from linked models don t be afraid to use them. Questions?
