THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 031100 Concrete Forming-5 <br /> <br />D. Construct forms mortar-tight and in a manner to permit removal without damaging the <br />concrete. <br />E. Verify that sleeves and other openings, offsets, recesses, channel chases, anchors, ties <br />and inserts are in place before concrete is placed. <br />F. Earth Forms: Footing forms may be omitted and foundation concrete may be placed <br />directly into neatly and accurately cut excavations, provided the excavation walls are <br />stable, a minimum of one inch and maximum of three inches outside the concrete edges <br />indicated on the drawings. <br /> <br />1. Where sides are unstable or excavations are not accurately cut to tolerances of <br />ACI 301, construct formwork to the extent required, at no additional cost to <br />Owner. <br /> <br />2. Hand trim sides and bottom of earth forms; remove loose dirt prior to placing <br />concrete. <br />G. Provide temporary openings in formwork at the base of wall and column forms to allow <br />inspection and cleaning before concrete placement. <br /> <br />H. Provide blackouts for mechanical and electrical work wherever necessary, even though <br />not shown on the Drawings. <br /> <br />I. Provide 3/4-inch (19 mm) chamfers for external corners. <br /> <br />J. Provide reveal feature strips as shown. <br /> <br />K. Plywood Forms at Exposed Surfaces: <br /> <br />1. Keep number of panel joints to practical minimum. <br /> <br />2. Ensure vertical joints are plumb and horizontal joints are level. <br /> <br />3. Align form ties vertically and horizontally. <br /> <br />L. Formwork for Architectural Concrete surfaces: <br /> <br />1. Conform to requirements of Architectural Concrete section of ACI 301. <br /> <br />2. Limit deflection of form facing materials between studs, as well as deflection of <br />studs and walers to 0.0025 times the clear span (L/400). <br /> <br />3. Arrange joints in facing material in geometric pattern as approved by the <br />University. <br /> <br />4. Locate form ties in symmetric pattern within panels as shown or as approved by <br />university. Use ties specified for Architectural Concrete. Provide "dummy" cones <br />where required to match pattern shown. <br /> <br />5. Form inside corners so that no concrete is placed against panel edges. <br />
