INDIAN RIVER COUNTY JULY 25, 2014 <br />INTERGENERATIONAL RECREATION CENTER 100% CONSTRUCTION DOCUMENTS <br />L. Coat contact surfaces of forms with form -release agent, according to manufacturer's written <br />instructions, before placing reinforcement. <br />3.2 EMBEDDED ITEMS <br />A. Place and secure anchorage devices and other embedded items required for adjoining work <br />that is attached to or supported by cast -in-place concrete. Use setting drawings, templates, <br />diagrams, instructions, and directions furnished with items to be embedded. <br />1. Install anchor rods, accurately located, to elevations required and complying with <br />tolerances in Section 7.5 of AISC's "Code of Standard Practice for Steel Buildings and <br />Bridges." <br />2. Install dovetail anchor slots in concrete structures as indicated. <br />3.3 REMOVING AND REUSING FORMS <br />A. General: Formwork for sides of beams, walls, columns, and similar parts of the Work that does <br />not support weight of concrete may be removed after cumulatively curing at not less than 50 <br />deg F for 24 hours after placing concrete. Concrete has to be hard enough to not be damaged <br />by form -removal operations and curing and protection operations need to be maintained. <br />1. Leave formwork for beam soffits, joists, slabs, and other structural elements that supports <br />weight of concrete in place until concrete has achieved at least 70 percent of its 28 -day <br />design compressive strength. <br />2. Remove forms only if shores have been arranged to permit removal of forms without <br />loosening or disturbing shores. <br />B. Clean and repair surfaces of forms to be reused in the Work. Split, frayed, delaminated, or <br />otherwise damaged form -facing material will not be acceptable for exposed surfaces. Apply <br />new form -release agent. <br />C. When forms are reused, clean surfaces, remove fins and laitance, and tighten to close joints. <br />Align and secure joints to avoid offsets. Do not use patched forms for exposed concrete <br />surfaces unless approved by Architect. <br />3.4 SHORES AND RESHORES <br />A. Comply with ACI 318 and ACI 301 for design, installation, and removal of shoring and <br />reshoring. <br />1. Do not remove shoring or reshoring until measurement of slab tolerances is complete. <br />B. In multistory construction, extend shoring or reshoring over a sufficient number of stories to <br />distribute loads in such a manner that no floor or member will be excessively loaded or will <br />induce tensile stress in concrete members without sufficient steel reinforcement. <br />C. Plan sequence of removal of shores and reshore to avoid damage to concrete. Locate and <br />provide adequate reshoring to support construction without excessive stress or deflection. <br />3.5 VAPOR RETARDERS <br />CAST -IN-PLACE CONCRETE 033000 - 12 <br />
