PART 3 - EXECUTION

3.1 ENVIRONMENTAL REQUIREMENTS:

3.1.1 Hot-Weather Installations: Masonry erected when the ambient air has a temperature of more than 99 degrees F, in the shade, and has a relative humidity of less than 50 percent shall be protected from direct exposure to wind and sun for 48 hours after installation.

3.1.2 Cold-Weather Installation: Cold-weather installation shall be in accordance with IMIAWC, Recommended Practices and Guide Specifications for Cold-Weather Masonry Construction.

INDEX - PAGE 20

3.2 PROTECTION: Facing materials shall be protected against staining. Top of walls shall be covered with non-staining waterproof covering or membrane when work is not in process.

Covering shall extend a minimum of 2 feet down on each side of the wall and be held securely in place. Before starting or resuming, top surface of masonry in place shall be cleaned of loose mortar and foreign material.

3.3 ERECTION: No unit having a film of water or frost on its surface shall be laid. Cutting of individual masonry units prior to installation shall be with power masonry saw. Masonry shall be laid plumb, true to line, with level courses accurately spaced. Bond pattern shall be kept plumb throughout. Corners and reveals shall be plumb and true. Vertical joints shall be shoved tight. Each unit shall be adjusted to final position while mortar is still soft and plastic. Any unit that is disturbed after mortar has stiffened shall be removed and relaid with fresh mortar.

Raked-out joints shall be kept free from mortar or other debris. Spaces around built-in items shall be solidly filled with mortar as each course is laid. The sizes of any two adjacent units shall be within permitted tolerances so that the difference between the vertical faces of such units shall not exceed 1/8 inch in exposed-to-view walls. Units in exposed-to-view walls shall be free from chipped edges or other imperfections detracting from the appearance of the finished work.

The airspace between the wythes shall be kept clear and free of mortar droppings by temporary wood strips laid on the wall ties and carefully lifted out before placing the next row of ties.

3.3.1 Preparation of Concrete Surfaces: Clean laitance, dust, dirt, oil, organic matter or other foreign materials from concrete surface upon which reinforced masonry is to be placed.

Use sand blasting, if necessary, to remove laitance from pores and to expose the aggregate.

3.3.2 Cutting and Fitting: Cutting and fitting, including that required to accommodate the work of others, shall be done by masonry mechanics. Wherever possible, full units of the proper size shall be used in lieu of cut units. Cut edges shall be clean, true, and sharp. Cutting of units shall be with power masonry saw for exposed block. Wet cut units, before being placed in the work, shall be dried to the same surface-dry appearance as uncut units being placed in the wall. Openings shall be carefully cut, formed, or otherwise neatly made for recessed items and for electrical, plumbing, or other mechanical installations so that wall plates, cover plates, or escutcheons required by the installations will completely conceal the openings and will have bottoms in alignment with lower edge of masonry joints. Webs of hollow masonry units shall be cut the minimum required for the installation.

3.3.3 Embedded Items: Spaces around built-in items shall be filled solidly with mortar. Anchors, ties, accessories, and other items required to be built in shall be built in as the masonry work progresses. Anchors, ties, and joint reinforcement shall be fully embedded in mortar. Cells receiving anchor bolts and cells of first masonry course below bearing plates shall be filled solidly with mortar or grout.

3.3.4 Unfinished Work: Unfinished work shall be stepped back for joining with new work. Toothing may be resorted to only when specifically approved. Before laying new work, INDEX - PAGE 21 loose mortar shall be removed and the exposed joint shall be thoroughly cleaned. Surfaces of clay or shale brick shall be dampened as required after cleaning to obtain good bond with subsequent work.

3.3.5 Mortar: Mortar shall be accurately measured in laboratory-established proportions and mixed with as much water as may be necessary to produce the wettest workable consistency possible. Mortar shall be placed in final position within 2-1/2 hours after mixing.

Mortar not used or that has started to set within this time interval shall be discarded. Mortar, that has stiffened within the above time interval, because of evaporation of moisture from the mortar, shall be retempered to restore its workability.

3.3.6 Jointing: Joints in exposed-to-view walls shall be tooled slightly concave with the mortar thoroughly compacted and pressed against the edges of the units. Tooling shall be done when the mortar is thumbprint hard. The tooled joints shall be finished to uniformly straight and true lines and surfaces, smooth and free of tool marks. Joint widths shall align with and match adjacent (approximately 3/8-inch wide).

3.3.7 Brick Units: Brick facing shall be laid with the better face exposed. Brick shall be laid in running bond with each course bonded at corners, unless otherwise indicated.

3.3.7.1 Solid Units: Bed, head, and collar joints shall be completely filled with mortar.

3.3.7.2 Hollow Units: Hollow units shall be laid as specified for concrete masonry units.

3.4 WEEP HOLES: Weep holes shall be provided not more than 600 mm (24 inches) on centers in mortar joints of the exterior wythe above wall flashing, over foundations, bond beams, and any other horizontal interruptions of the cavity. Weep holes shall be formed by using weep hole ventilators. Other methods may be used for providing weep holes upon approval of the Contracting Officer. Weep holes shall be kept free of mortar and other obstructions.

3.5 PLACING REINFORCING STEEL: Prior to placing grout, clean all reinforcement of loose, flaky rust, scale, grease, mortar, grout, or other coating which might destroy or reduce its bond with the grout. Unless otherwise indicated, the details of reinforcement shall conform to ACI SP-66. Do not bend or straighten reinforcing in a manner injurious to the steel. Do not use bars with kinks or bends not shown on the drawings. Placement of reinforcement shall be inspected and approved prior to placing grout. Vertical bars shall be spliced only where indicated. Unless otherwise indicated, vertical wall reinforcement shall extend to within 50 mm (two inches) of tops of walls.

3.6 SHRINKAGE-CRACKING CONTROL, JOINT REINFORCEMENT: Joint

reinforcement shall be installed as indicated. Reinforcement shall be placed so that longitudinal

INDEX - PAGE 22

wires are centered on the wall or wythe and are fully embedded in mortar for their entire length.

Reinforcement at openings shall extend not less than 24 inches beyond the end of lintels or the end of the panel if the distance to the end of the panel is less than 24 inches. Reinforcement shall be lapped 6 inches or more for deformed longitudinal wires and 12 inches or more for smooth longitudinal wires. Factory-fabricated sections shall be installed at corners and wall intersections.

3.7 POINTING AND CLEANING: After mortar joints have attained their initial set, but prior to hardening, mortar and grout daubs or splashings shall be completely removed from masonry-unit surfaces that will be exposed or painted. Before completion of the work, all defects in joints of masonry to be exposed or painted shall be raked out as necessary, filled with mortar, and tooled to match existing joints. Masonry surfaces shall not be cleaned, other than removing excess surface mortar, until mortar in joints has hardened. Masonry surfaces shall be left clean, free of mortar daubs, dirt, stain, and discoloration, including scum from cleaning operations, and with tight mortar joints throughout. Metal tools and metal brushes shall not be used for cleaning. Concrete-masonry-unit surfaces shall be dry-brushed at the end of each day's work and after any required pointing.
