C. Units shall be laid to preserve vertical continuity of cells to be filled. The vertical alignment shall be
sufficient to maintain a clean, unobstructed flue measuring not less than 3"x3". Place no units or cut
pieces of masonry less than 4" nominal.
D. In placing mortar in horizontal joints, completely cover the face shells of each unit with mortar. Solidly fill
all head joints to the thickness of the face shell and shove units tightly in place. Solidly bed in mortar all
head and cross web bed joints adjacent to cells to be grouted to prevent leakage of mortar.
E. Lay designated walls in two separate wythes, with insulated cavity as indicated.
F. Anchor and bond intersecting masonry walls with 50% masonry bond, except as noted otherwise on
drawings.
G. Install precast and/or composite steel lintels over all openings. Set lintels in place with joints pointed to
match adjacent work. Build in lintels, reinforce and fill with structural concrete grout as work progresses.
1. Steel lintels shall be provided with 3" minimum structural bearing each side of openings.
2. Pre-cast concrete lintels shall be provided with 8" minimum structural bearing each side of
openings.
3. Typical steel and cut masonry lintels, even if not shown on structural or architectural drawings,
shall be reinforced with a minimum of 1 #5 bar continuous (extend 12" minimum each end) and
grouted solid.
4. Concrete masonry work shall not proceed beyond the elevation of door and window headers
until all vertical reinforced cells and reinforced horizontal lintels have been grouted.
H. At hard tile locations take extra care in laying units such that wall will be suitable for thinset tile installation
directly to wall. Grind any unevenness judged unacceptable by ARCHITECT.
I. Install wall control/expansion joints at 20 ft. o.c. and/or as shown and detailed on
architectural/engineering drawings. Refer to Sections 04000/Masonry, General and 07920/Sealants,
Caulking and Seals for additional requirements.
3.04 CUTTING
A. Do all cutting of block with carborundum or equivalent saw. To facilitate proper coursing, half blocks may
be used to reduce amount of cutting. No masonry will be permitted to be used if not cut properly.
Masonry broken by "blows" will be replaced, even if found after the wall has been completed.
3.05 PLACING STEEL REINFORCEMENT
A. Reinforcing steel to be straight, except for bends around corners and as detailed otherwise on drawings.
Lap reinforcing steel 48 bar diameters minimum. Place vertical bars in exact center of cells, or as
otherwise indicated, and hold in position at top and bottom and at intervals not to exceed 96 bar
diameters. Vertical cavity rebar to be run in maximum possible lengths, 5'-0" minimum, using low lift
grouting procedures.
B. Completely embed joint reinforcement in mortar or grout. Lap splices 6 inches minimum at all locations.
C. Lap dowels in footings to vertical steel in masonry columns by placing in aligned cells, then grouting cells
to obtain bonded lap between wall and footings.
D. Reinforce and grout all reinforced horizontal block courses, as wall is built-up.
