Floor Framing Objectives• Walls need to be framed on a square level floor
system built to precise plan dimensions.
• The floor framer should expect a foundation that was
poured to these industry standards.
• The floor framer must verify the foundation's condition
by checking for any problems.
• Any condition that is not correct with the foundation
needs to be corrected during or before the floor
framing installation.
• If the problems are not corrected, they will compound
and cause more problems over the course of the job.
