1 PHJN1010CU SECTION 0400 MASONRY A. MASONRY 1. General Requirements: Division One is applicable in full hereto. 2. General: Workmanship shall be first class, with horizontal courses level, vertical joints in alternate courses aligned. Carry work up level where possible; step back for joining new work (toothing not permitted). Do not work when mean daily temperature is below 40 degrees F, or such condition is anticipated within 24 hours. Carefully stack masonry materials on platforms and cover with waterproof sheeting. Cover top of unfinished walls at end of each days work, and when rain appears imminent, with waterproof material which overhangs the wall at least 2 feet. Cover bottom of finished walls with a 4 foot wide strip of plastic to prevent staining. Keep cavity type walls clean of mortar droppings and debris by use of a wood lift-strip placed on ties and raised with every 16" lift. Hose test effectiveness of flashing, weeps, etc. as walls are erected. 3. Built-in Work: Build in anchors, inserts, door frames, lintels, duct opening sleeves, etc. shown or required. Fill in solid with mortar behind hollow metal door frames and in first cell adjacent to frame. 4. Typical Exposed Brick: Modular size face brick meeting ASTM C-216, as selected. Include in bid allowance of $ per thousand for purchase, sales tax, delivery and unloading. If brick selected cost more or less than allowance, contract price will be adjusted. Secure with order sufficient solids for use where sides are exposed, and arrange for delivery on banded pallets and premixed from all kiln runs for job. Submit sample panel for approval indicating range, flashing, etc. as producer proposes to supply. Submit in writing the estimated quantity of brick required to facilitate contract adjustment. Cull out chipped brick, which will be obvious in finish work. Lay in running bond so that 3 courses equal 8" (to align with backup), joint faces concave tooled. Lay out courses in advance on story rod. Shove each brick into place producing solid and uniform bed and head joints. Lay out horizontal coursed dry before actual laying begins to check dimensions and to insure that full courses will check in with openings, pilasters, etc. Use no face brick less than half-brick unless approved by Architect and cut to size with masonry saw. Provide solid brick at screen wall. Lay in pattern shown. 5. Concrete Block: Steam-cured hollow lightweight load-bearing concrete masonry units meeting ASTM C-90, Grade N-1. Faces smooth and dense, uniform in texture and free of any defect detrimental to finish appearance. Furnish jamb, lintel, corner, cap blocks and other special shape required. All 8" units shall meet International Building Code requirements for 2-hour fire resistance rating, and all 12" units shall meet 4-hour requirements. PH&J Architects, Inc. - All rights reserved Page

2 PHJA/1010CU Cut dry and do not wet or allow to become wet before or during laying of wall. Lay in running bond so that one course equals 8" in height, 16" in length. Where possible lay out work to course block horizontally and vertically, taking care that masonry will course up through openings, etc. V-tool exposed joints. 6. Mortar: Mix typical mortar as one part Magnolia Masons Mix to 2% parts sand and meeting ASTM C-144, mixed in mechanical mixer to produce ASTM C-270 Type N mortar. For masonry below grade employ Type M mortar mixed as 1 part masonry cement, 1 part portland cement and 2% parts sand; do not use in exposed work. Where new work joins existing work, select a masonry cement brand which will produce color matching existing mortar. Run trial batches to secure approval of selection. 7. Fill In Masonry Below Grade: Fill wall cavity and cells of all masonry units below grade with concrete as soon as practical after laying. Pour in levels not exceeding two feet. See Concrete Division for mix. B. MASONRY REINFORCING AND BONDING 1.
