Integrating VDC into Everyday Projects

Transcription

1 Integrating VDC into Everyday Projects VIRTUAL DESIGN & CONSTRUCTION AT HOLDER CONSTRUCTION December 12, 2005 Virtual Builders Roundtable Michael Kenig, Holder Construction Company

2 Overview Holder and BIM: Some Basic Philosophies Highlight Some Experiences Benefits, Challenges, and Lessons Learned Updates - Some Industry Ongoing Efforts

3 Holder and BIM Basic Philosophies: A question of when, not if! Only for Gehry-esque type projects? BIM Projects fall into 1 of 2 categories 1. Designed (in 3D) 2. Conversion (to 3D) To date, no Gehry-esque ; only Conversions

4 Virtual Design and Construction Building Information Modeling BIM Update Excerpted From Internal Holder Presentation

5 WHAT WE RE DOING WORKS FINE!! Why Change? GET REAL. WE RE IN THE FIELD. WE RE BUILDERS!!

6 Why Change? HOW S THAT WORKING FOR YOU NOW??? WOULD YOU RATHER FIND OUT IT S WRONG BEFORE YOU GET OUT IN THE FIELD, OR AFTER??!

7 What Is BIM? Building Information Modeling Virtual Design & Construction Object Based. Parametric.

8 Coke Foundations: Scope Clarification BIM Examples

9 Holder BIM GuideBook What Holder s Doing?

10 Jump In Get Wet Splash Around!

11 BIM Benefits 1. Visualization Infinite cut sections/drawings 2. Conflict, Interference and Collision Detection 3. Scheduling and Phasing What if s 4. Sequencing, Workflow, Safety and Site Logistics 5. "Smart Drawings": Estimating and Quantity Extraction 6. Scope Clarification, Trade Coordination and Options Analysis 7. As-Builts, Facility Management, and BD uses and many others we are still discovering!

12 Examples of Benefits Options Analysis (Value Engineering) Scope Reconciliation (comparisons) Virtual Mock-Ups Brick Precast

13 Progressive Data Center Phases started / used: Conversion from 2D What was modeled: Entire Project Who did the modeling: Outsourced

14 Logistics And Sequencing

17 Coordination

18 Making the Business Case 2D HVAC Plan 3D Overhead Rendering of Areaway 2D Pipe Plan Issue: Issue: Generator exhaust pipe and battery room exhaust duct conflict in areaway. Result: Duct penetrations through precast wall panels were relocated and generator exhaust pipe routing was modified in field. Potential Cost Savings = $60,000 Photo of Installation

19 Challenges / Lessons Learned Conversions on Fast-Tracked Projects Level of Granularity, decide early Prefabrication: Higher quality, lower cost File Sharing: FTP Site (two way)

20 Challenges / Lessons Learned Trusting the Data (side-by-side estimates) Visualization is the low hanging fruit The 3 Fears ( for our convenience ) Changing our Everyday Processes

21 Update on Other Ongoing Efforts CURT OAEC Productivity (AGC Report) AGC PIAC s BIM Taskforce AIA / AGC Joint Committee Survey One of the limitations of 2D drawings is that only people can read them. Chuck Eastman, GA Tech

22 CURT WP-1202: The Case for Change (Owners!) The Drivers: Owner Leadership Integrated Project Structure Open Information Sharing Bldg. Info Models (BIM)

23 Impact of Shifting Curve to the Left On Contractors? On Owners? X X X

24 Optimized Process - FCFIHP Teams (Follow up Whitepaper from CURT) Strategy Organize Differently / Technology Many Teams already Collaborative / Integrated

25 Where are builders on this? (AGC Report to CURT Conference, Nov. 8) Only a Few Early Adopters Leading the Way Looking for Anything that Will Help Need Designers to use the Technology New Position Project Modelers Conversions (temporary during transition)

26 AGC s Private Industry Advisory Counsel (PIAC) BIM Task Force Owner s Perspective Challenges Limiting Implementation Barriers Implementation (removing them) Regarding BIM, we need to get past the what it is and focus on what it does! Jonathan Widney, President of Navisworks
