3 What to Expect: STRUCTURAL LOD Who What When Where Why How

4 Is this important to my job / my business? STRONGLY AGREE if Architect Structural Engineer Mechanical Engineer Contractor Sub-contractor Owner Legal

5 DIALOG

6 Wills Background Licensed Practicing Professional Engineer (TX) Masters in Structural Engineer Washington Univesity in St. Louis Focus in parametric modeling of structure (96-98). Areas of interest are Structures Envelope BIM & VDC Director of IPD Department at RLG, Inc.

7 Co-Chair SEI – CASE Joint Committee on BIM Co-Chair Designers sub-forum Committee member Technology Integration Committee American Concrete Institute ACI Committee 131 BIM Glass Association of North America BIM Task Force Wills Background

8 Brenda's Background Founded Ikerd Consulting LLC and its subsidiary i2concepts beginning in Started working with Revit Structure V2 (05) Co-Authored Autodesk's 2011 Structural Educational Curriculum Co-authoring book on Virtual Design and Construction (VDC) with Navisworks in both Spanish and English.

9 Major Take Away Everything should be made as simple as possible, but not one bit simpler. Albert Einstein

10 TYPES OF BIM MODELS 10 CLASH DETECTION VALUE ENGINEERING DIM. CONTROL DOCUMENTATION FABRICATION FIELD BIM

11 LOD & FEDERATED MODEL 11 Custom Programming In VB & VB.net Bentley Architecture Revit Architecture 3D Civil Revit Structure Bentley Structural Revit MEP & Bentley Mechanical InventorSolidWorksProE

12 LOD and Origin LOD Should Clearly Defined the X,Y,Z origin

13 Design Ikerds Ideas for Structural Design LOD 1. Avoid re-modeling 2. Clearly Define the local X,Y,Z Origin 3. Model Content Shown on Typical 1/8" Plan 4. Model Structure as it will be Constructed 5. Do Not Duplicate Model Content (A,S & M) 6. Use Shared Model for 2 Discipline content

14 Design Ikerds Ideas for Structural Design LOD 7. Don't Assume Construction Methods 8. Match BIM material w/ specifications 9. Engineers Open & Review their BIM 10. Not All Steel, Concrete is Structural 11. Train inside & out on Structural BIM LOD

15 AIA E202 BIM Protocol Exhibit

16 AIA E202–2008 LOD 100: Many items modeled. Masses & sq.ft. 200: Geometry is established but no object data 300: Engineered sizes of objects are established 350? Fully coordinated federated model? 400: Shop drawing & committed purchase price 500: As Built Model, complete. 16

17 Why Define a Structural BIM LOD of 350 Theres many a slip between the cup and the lip
