Integrating VDC into Everyday Projects

VIRTUAL DESIGN & CONSTRUCTION AT HOLDER CONSTRUCTION

December 12, 2005 Virtual Builders Roundtable

Michael Kenig, Holder Construction Companymkenig@holder.com

Overview

• Holder and BIM: Some Basic Philosophies

• Highlight Some Experiences– Benefits, Challenges, and Lessons Learned

• Updates - Some Industry Ongoing Efforts

Holder and BIM

• Basic Philosophies:– A question of “when”, not “if”!– Only for “Gehry-esque” type projects?

• BIM Projects fall into 1 of 2 categories1. Designed (in 3D)2. Conversion (to 3D)

• To date, no “Gehry-esque”; only “Conversions”

Why Change ?WHAT WE ‘RE DOING WORKS

FINE!!

GET REAL. WE’RE IN THE FIELD.

WE’RE BUILDERS!!

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 ??!

BIM Benefits1. 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!

Examples of Benefits

• Options Analysis (Value Engineering)• Scope Reconciliation (comparisons)• Virtual Mock-Ups

Brick Precast

Progressive Data Center

Phases started / used: “Conversion” from 2D

Coordination

Making the Business Case

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

Challenges / Lessons Learned

• Conversions on “Fast-Tracked” Projects

• Level of Granularity, decide early

• Prefabrication: Higher quality, lower cost

• File Sharing: FTP Site (two way)

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

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.

CURT WP-1202:The Case for Change (Owners!)

The Drivers:

• Owner Leadership

• Integrated Project Structure

• Open Information Sharing

• Bldg. Info Models (BIM)

Impact of Shifting Curve to the LeftImpact of Shifting Curve to the Left

On Contractors?

On Owners?

“Strategy” – Organize Differently / Technology

Many Teams already Collaborative / Integrated

Optimized Process - FCFIHP Teams (Follow up Whitepaper from CURT)

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)

“Where are builders on this?”(AGC Report to CURT Conference, Nov. 8)

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”!
