Construction is due for a Henry ry Ford moment!

Higher productivity in the construction industry could:

create $1.6 trillion additional added value per year
boost global GDP by 2%

Problem exacerbated in U U.S .S. . construction

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

Economic consequences by 2025

$3.9 trillion losses to GDP
$7 trillion lost business sales
2.5 million lost American jobs

America’s Infrastructure Score:

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

An order of magnitude increase in productivity is possible by changing how we build.
