SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br />UNIT MASONRY 040500-12 <br />D. Space continuous horizontal reinforcing as follows: <br />1. For multi-wythe walls (solid or cavity) where continuous horizontal reinforcing also acts as <br /> structural bond or tie between wythes, space reinforcing as required by code, but not less than <br /> 16 inches o.c. vertically. <br />2. For single-wythe walls space reinforcing at 8 inches o.c. vertically, unless shown otherwise. <br />3. Install reinforcing in the two courses immediately above and below all openings. <br /> <br />3.08 <br /> <br />ANCHORING MASONRY TO STRUCTURAL MEMBERS: <br />A. Anchor masonry to structural members where masonry abuts or faces structural members to <br />comply with the following: <br />1. Provide an open space not less than 1-inch in width between masonry and structural member, <br /> unless otherwise indicated. Keep open space free of mortar or other rigid materials. <br />2. Anchor masonry to structural members with flexible anchors embedded in masonry joints and <br /> attached to structure. <br />3. Space anchors as indicated, but not more than 16" o.c. vertically and 32" o.c. horizontally. <br /> <br />3.09 MOVEMENT (CONTROL AND EXPANSION JOINTS): <br /> <br /> <br />A. General: Install control and expansion joints in unit masonry where indicated and as required by <br />Code. Build in related items as the masonry progresses. Do not form a continuous span through <br />movement joints unless provisions are made to prevent in-plane restraint of wall or partition <br />movement. If no joints are indicated, follow guidelines of BIA or NCMA. Verify all locations <br />with Architect. <br /> <br />B. Form control joints in concrete masonry as follows. <br />1. Install preformed control joint gaskets designed to fit standard sash block. Keep head joints <br /> free and clear of mortar or rake joint. <br />2. Locate joints as recommended by NCMA or as shown on Drawings. Do not exceed 25' <br /> between joints or change of plane in wall surface. <br /> <br />C. Form expansion joints in brick made from clay or shale as follows: <br />1. Form continuous open joint of size indicated (typically 1/2 inch) but not less than 3/8 inch for <br />installation of sealant and backer rod. Maintain joint free and clear of mortar. <br />2. Locate joints as recommended by BIA or as shown on Drawings. Do not exceed 25 ft. <br /> between joints or change of plane in wall surface. <br /> <br />D. Build in horizontal pressure-relieving joints where indicated; construct joints by either leaving an <br />air space or inserting pressure relieving pads of width required to permit installation of sealant and <br />backer rod. <br />1. Locate horizontal pressure-relieving joints beneath shelf angles supporting masonry veneer <br /> and attached to structure behind masonry veneer. <br />E. Align control joints and expansion joins in multi-wythe construction. <br /> <br />3.10 <br /> <br />LINTELS: <br />A. Install steel lintels where indicated. <br /> <br />B. Provide masonry lintels where shown and wherever openings of more than 1 '-0" for brick size <br />units and 2 '-0" for block size units are shown without structural steel or other supporting lintels. <br />Provide precast or formed-in-place masonry lintels. At exposed walls, utilize U-blocks cast with <br />concrete and reinforcing bars, fabricated to match size and [mish of exposed masonry .Cure <br />precast lintels before handling and installation. Temporarily support formed-in-place lintels for a <br />minimum of 72 hours or until cured enough to hold applied loads. <br />
