David Epps BIM Department Manager at Holder Construction Company 12 years in the construction industry Last 7 years with Holder in BIM Department Previous 5 in residential construction industry Involved with BIM / VDC for 9 years Autodesk Product User for 11 years; Revit CP Worked on / Managed 40+ projects on and off the jobsite leveraging BIM Contributing author of AGC BIM 101 & Contractor s Guide to BIM Active member of the BIMForum Emerging Leaders President of Atlanta Revit Users Group HOLDER CONSTRUCTION» Established 1960» 85% Repeat Clients» Team Approach Builders» $1.6 Billion Annual Revenue» Experience in 5 Countries & 30+ States» 15th (ENR Top 100 CM At-Risk)» 31st (ENR Top 400 Contractors)» 9th (ENR Top 100 Green Contractors)» 150+ BIM Projects To Date» 20 Full Time BIM Associates

2 Established 1955 Second Generation Family Owned Business Areas of Operation: Northern California and anywhere else our customers take us Construction Employers Association s safety award for the past four years Primary focus is Integrated Lean Project Delivery Providing Preconstruction and Construction Services All Projects Done Using VDC Full Time VDC Employees Historical Restoration and Renovation Healthcare Affordable Housing Retail For Other Examples Visit Our Website at Hospitality K-12 Schools Higher Education Residential Tenant Improvement 1) 2) 3) Subcontractor Procurement 4) Meeting 5) BIM Assessment Meeting Project Executive Project Manager Superintendent BIM Manager BIM Engineer Project Engineer(s) MEP Manager Scheduler Foreman 3 4

3 Establish our own goals What is keeping our superintendents up at night? Civil Earthwork What can we do to facilitate? QTO Construct. Wall Analysis Connection Crane Site Logistics Placement 4D Schedule Animation Reflect on past projects Successes What will we fund ourselves? Missed Opportunities Continuous Improvement A(BIM)inations 5 6

4 VDC Survey Used to Understand Customer Value Comprehensive survey of VDC Participants 90 participants sent surveys 30 full respondents 9 partial respondents Roles of Participants Owner reps Design Professionals General Contractor (Herrero Employees) Subcontractors (Mangers and Detailers) VDC Services - Value 1. Goals & Uses 2. Process 3. Information Exchange 4. Technical Requirements The VDC process The VDC process improved the planning improved or protected of my scope of work my financial interest in The process Herrero The VDC process the project used to facilitate VDC improved the quality of was valuable my deliverables 7 8

5 1. Goals & Uses a) Intro b) Project Summary Level of Detail & Progress Tracking Milestones for Deliverables Definitions c) Project Milestones / Phases d) Team e) Goals LOD of Object What to Model Responsible Party Completion Level 2. Process a) Holder BIM Process b) Model Progression Spec c) Model Responsibility Matrix d) Meetings e) Training 3. Information Exchange a) Model Exchange Requirements b) Model Transfer Protocol - FTP Site / File Hosting - File Naming Conventions - Upload Notifications - Deliverables 9 10

6 4. Technical Requirements a) Software / Hardware / Infrastructure Customized Protocol for Large Projects b) 2D/3D File Exchange c) Tech. Standards / Model QC d) 3D Coordination e) 4D Phasing Model Requirements f) QTO Model Standards g) Facilities Management h) Metrics / Tracking i) Closeout Links Autodesk - BIM Deployment Plan, Sample Contents building SMART alliance, Veterans Administration, Indiana University, Los Angeles Community College District, McGraw-Hill Construction, NIBS WBDG - Whole Building Design Guide, OmniClass A Strategy for Classifying the Built Environment, Penn State BIM Execution Guide, and TFC - Texas Facilities Commission, Wisconsin Division of State Facilities BIM Guidelines,

7 Create the Project Vision Create the Project Vision Production Planning (4D) & Visual Estimating (5D) Create the Project Vision Legend & Spatial Coordination (3D) Create the Project Vision FM, File Sharing & Lean Tools 13 14

8 Subcontractor Procurement Establishing Partnerships with Subs a) Established trust b) Task efficiency c) Predictable / standardized work d) Reduced contingency e) Schedules are met or beat Subcontractor Procurement Subcontractor Procurement What s in the RFP? Subcontractor Procurement Saved Money on Past Projects Happy Subcontractors Competitive Pricing Owner Value 15 16

9 Subcontractor Procurement Qualification / Selection of Company Sub needs to clearly show competence. Don t accept oh, we do that all the time Have them show you how they plan to model Qualification Test for Modeler Obtain work flow from company for modeling Project BIM Manager to test Can t do the work, can t be on the project Sets subs up for success 1. Software 2. Model Scope Overview 3. BIM Coordination Schedule 4. File Sharing 5. Viewing Coordination Issues In Navisworks 6. BIM Coordination Log 7. Space Constraints 8. Drawing/Model Standards 9. Contact Information 10. Establishing Building Tolerance for Models Software 17 18

10 Model Scope Overview File Sharing Buzzsaw Projectwise BIMRoom Horizontal Glue Sharepoint Constructware Dropbox Box.net J/K! BIM Coordination Schedule File Sharing 19 20

11 Viewing Coordination Issues Coordination Log Isolate clash categories by trades Illustrate graphically problem clash types that need to be addressed Track Project Improvements over time Document key events impacting number of clashes recorded Clash History Report Excel Document Coordination Log Space Constraints 21 22

12 Constraint Log Constraint Log and Backup: Use of constraint log to itemize issues that need input beyond the immediate detailing team for resolution Use back-up documentation form to provide additional information to concerned or interested parties to help resolve constraint Issue number ties document to issue log Issue text description of issue Image Snapshots from models or other documents annotated to illustrate the issue Solution Suggestions Possible solutions developed by the project VDC team Images Sketches or snapshots of proposed solutions Establishing Building Tolerance for Models Drawing / Model Standards Practice Clash Avoidance 23 24

13 Layering File Orientation Model Color / Appearance Contact Info Establish Common X/Y/Z What happens when you don t 25 26

14 What happens when you don t What happens when you don t What happens when you don t Establish Team Goals From Vision Communication Is Paramount Garbage In Garbage Out 27 28

15 For Handover / Facilities Management Deliverable Goals again Finish Strong DON T FOGET THE CLASS SURVEY! It would have been SO much easier IF Focus on what matters DOH!
