24) After drilling, REMOVE DUST thoroughly from
each hole using compressed air and/or bristle
brush. Make certain that the columns remain
aligned with the chalk line.
25) Assemble the washers and nuts on the anchors
then tap into each hole with a hammer until the
washer rests against the base plate. Be sure that
if shimming is required, enough THREADS ARE
LEFT EXPOSED. ( See Fig. J)

Tighten each anchor nut to 80 ft. lbs.
26) If shimming is required, insert the shims as
necessary under the base plate so that when the
anchor bolts are tightened, the columns will be
plumb. (See Fig. K)
27) After any necessary shims are installed, tighten
each anchor nut to 80 ft. lbs. IMPORTANT - If
anchor bolts do not hold when torqued to required
amount, concrete must be replaced. Saw cut
and remove 24” x 24” square area under each
column base then repour with reinforced 3000 PSI
concrete to a depth of six inches minimum, keying
new concrete under existing floor. (See Fig. L)
