Problem exacerbated in U.S. construction
• U.S. construction: stuck at the same level since 1960s
• Other sectors: up to 1500% productivity boost

Labor shortage
Skill shortage / lack of expertise
Inadequate planning / scheduling
Siloed industry
Idle time waiting for material / supply delivery
Lack of collaboration / communication between stakeholders
Current Construction Practice 10
An order of magnitude increase in productivity is possible by changing how we build.
