3.01 ERECTION, INSTALLATION, APPLICATION

1. General Requirements for Concrete Masonry Walls: See Section 04220 Concrete Units Masonry for other general requirements.

Fully mortared head and bed joints are critical when integrally colored architectural units are specified and polyurethane insulation is used. Bee holes in joints may allow polyurethane insulation to seep through and stain the face of the block. Running bond is standard, but, other bonds (i.e. stack) are possible with proper engineering. Revise the following paragraph if other bonds are to be used.

   2. Bond shall be plumb throughout face of wall.
   
   
3. Wall Intersections: In accordance with Section 04220 - Concrete Masonry Units.
   
   
4. Mortar Joints: In accordance with Section 04220 - Concrete Masonry Units.

Drawings must indicate location and spacing. Spacing and location of joints should be verified with Structural Engineer.

   1. Provide control joints at locations indicated.
   2. Construct control joints as detailed on drawings.

Verify reinforcing requirements for each project. Following text is representative of requirements which should be verified by Structural Engineer or its appointed representative.

6. Horizontal Joint Reinforcing: As indicated on the wall system design drawings and in accordance with Section 2106 of the U.B.C. , or Section 2106 of the International Building Code 2000.
