observed to be acceptable with project specifïcations. Copies of reports are on file with
Mr. Ken Pennington with Musick Built Construction, Inc.
Visual welding inspection was conducted on the perimeter angle ñllet welds and
the bar joist fillet welds for the mezzanine. I observed the perimeter angle welded to the
f¡amework using 2" welds on 12" centeß and that the perimeter angle was welded to
make it I continuous piece. I observed the bar joists were welded oá each end with a
minirnum weld of I t/z'".lJpon completion, I observed all fillet welds to be in compliance

"snug tight"' I inspected all a¡rchors with a r¡nench for the co¡rect-tensioning. Upon
completion, I observed all anchors to be in compliance with project specifiJations.

bolts to be ASTM A325 plain body bolts with a hardened flat washer properly positioned
under the turning surface of a hearry hex nut. I observed the bolts for ihe r-uít"t
eonnections to be I" while the larger connections were I 118" bolts. With Mr. Kaufman
