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.
