Innovation in Quality Control

• What? FAST REMOTE CONSTRUTION MONITOR (FRCM)

• Why? Ensure inspection quality by empowering engineers

• How? Document quantity, quality in Cloud

Remote observation

Field Engineers

Contractors

Preset inspection schedule

and locations

• Foundations, Floors at critical locations and time

Data collected and photos taken will be uploaded to the ECP via App

UPLOADING:

• When the building is done per FRCM, then “Gold Star”

• Gold Star buildings will be shown on a map that is open to the public.

Public Recognition of Good Construction

Haiti 2018

• Massive reconstruction effort affected today’s construction quality

• Extensive mason training programs and public outreach programs

Capacity Building is a Critical Part of it.
