panels where practicable. Follow CMU layout indicated on Drawings.
C. Lay-up walls plumb and true and with courses level, accurately spaced and
coordinated with other work.
D. Built-in Work: As construction progresses, build in items specified in this and other
Sections. Fill in solidly with masonry around built-in items.

place a layer of monofilament screen such as Dur-O-Wal's Dur-O-Stop in the
joint below and rod mortar or grout into core.
E. Fill space between steel frames and other openings and masonry solidly with
mortar unless otherwise indicated.
F. Grouting: Do not place grout until entire height of masonry to be grouted has
