Listed below is a list of steel buildings check points to use
when plumbing all wall columns. Using a carpenter's level
will show if they are not plumb.
Uneven concrete at the base of columns is the most
common culprit. Sometimes dirt, pebbles, or debris is hidden
beneath the base plate. Simply removing the column and cleaning
away the debris will plumb the column. Other times the concrete
has set up unevenly in which case metal shimming is required.
Torque anchor bolts tight after shim is in place. Check for plumb.
Repeat process with thicker or thinner shim if required.
Improperly set anchor bolts that are too far apart
or too close together will cause unleveled metal buildings frames.
Minor shimming at the haunch and peak will correct this.
