<strong>ERECTION</strong> <strong>AND</strong> <strong>SAFETY</strong> <strong>MANUAL</strong><br />
To plumb the braced bay without a transit, run a chalk line from out of fl ange to out of fl ange of columns<br />
on the foundation (per drawing). Drop plumb bob(s) from rafter fl ange(s) and square the frame using the<br />
rod bracing for leverage.<br />
To plumb the braced bay lengthwise using a transit, sight in the transit parallel to the base of the frame<br />
columns by using a position a few inches from the frame line (See sketch). Make sure transit is level.<br />
Check frame by reading tape through transit. First bring columns into plumb, then rafters, by adjusting<br />
diagonal bracing. Take all measurements from centerline of fl ange. Take a measurement at the base of<br />
the columns and adjust the bracing to correct the transit reading at the rafter measuring location. Once<br />
the frame is plumb, all connection bolts and anchor bolts should be tightened.<br />
