H.
Strike joints facing cavity, flush.
I.
Provide anchoring devices of type shown and specified in construction
documents. For conditions not shown or specified, provide standard type for
facing and back-up involved.
J.
Lintels
1.
Install loose lintels of steel and other materials where shown.
2.
Provide masonry lintels where shown and wherever openings of more
than 1’-0” are shown without structural steel or other supporting
lintels. Provide precast or formed-in-place masonry lintels.
Thoroughly cure precast lintels before handling and installation.
Temporarily support formed-in lintels.
3.
For hollow masonry unit walls, use specially formed "U"-shaped lintel
unit-with reinforcing bars placed as shown and filled with Type S
mortar or concrete grout.
K.
Control & Expansion Joints
1.
Provide vertical expansion, control and isolation joints in masonry.
Build-in related masonry accessory items as masonry work progresses.
2.
If location of control joints is not shown, place vertical joints spaced
not' to exceed 30'-0" o. c. Review location of joints with Architect
before execution.
Remove and replace masonry units which are loose, chipped, broken, stained
or otherwise damaged, or if units do not match adjoining units as intended.
Provide new units to match adjoining units and install in fresh mortar or grout,
pointed to eliminate evidence of replacement.

2.
Stonework
A.
Fabricate and install stonework to withstand normal loads from wind, gravity,
movement of building structure, and thermally induced movement, as well as
to resist deterioration under conditions of normal use including exposure to
weather, without failure.
B.
Provide stonework which is designed, fabricated and installed based on the
following safety factors applied to minimum physical properties of stone
indicated.
1.
Safety Factor for Limestone and Sandstone: 8
a.
Provide hand-set stone anchoring system which results in
attachments developing the capability to sustain the following
forces generated by the supported element (individual member
or assembly) acting separately, based on the yield strength of
the material:
b.
A total force of 4 times the dead weight of the element
supported, app1ied vertically downward through the element's
center of gravity, combined with loads caused by thermal
movements.
c.
A total force of 2 times the dead weight of the element applied
horizontally outward through the center of gravity of the
element, combined with loads caused by thermal movements.
