with an oversize screw fastener and gasketed washer; however, panels with
an excess of such holes or with such holes in critical locations shall not
be used. Exposed surfaces shall be kept clean and free from sealant, metal
cuttings, excess material from thermal cutting, and other foreign
materials. Exposed surfaces which have been thermally cut shall be
finished smooth within a tolerance of 3 mm.1/8 inch. Stained, discolored
or damaged sheets shall be removed from the site. Welding of steel shall

holes in structural beam or column webs, will not be permitted. Concrete
work is specified in Section [03300A CAST-IN-PLACE STRUCTURAL CONCRETE][
03300N CAST-IN-PLACE CONCRETE]. Anchor bolts shall be accurately set by
template while the concrete is in a plastic state. Members shall be
accurately spaced to assure proper fitting of panels. As erection
progresses, the work shall be securely fastened to resist the dead load and
wind and erection stresses.
