How do we define “Waste?”

Learn to See Waste

Why? “Construction As Production”

Use Manufacturing Template:

U.S. Construction = $1.3 Trillion Industry (2008)

57% - 26% = 31% MORE Waste in Construction Processes

31% x $1.3 Trillion = $403 Billion of “Avoidable” Waste

Improve Building Production and Eliminate Waste By Only 10% =

$40 Billion POTENTIAL Savings

The Problem The Strategy

Lean Construction

Principles of Lean Construction:

1. Value defined by the customer and in the customer’s language

2. Organize work to produce only the value promised

3. Make the work flow along the value stream

4. Do the work at the pull of the customer

5. Pursue perfection

Paradigm Shift

BIM+Lean+Green – February 02, 2012

BIM – Collaboration Platform

Integrated Design and Sustainability

Lean Construction Strategies

• More building for the same investment • Collaborative design process

• Reduced variance – lower contingency • Shared incentive plan results in 5% savings

• Predictable delivery • Minimize Handoffs with Design Build Trades = Minimize Field RFIs

• Maximized Productivity • Increased prefabrication results in 20% Less Field Labor

• Less material waste • 50% less waste due to prefabrication
