Unless otherwise indicated on <br /> Drawings, locate vertical joints beside piers integral with walls, near corners, and in <br /> concealed locations where possible. <br /> C. Control Joints in Slabs-on-Ground: Form weakened-plane control joints, sectioning concrete <br /> into areas as indicated. Construct control joints for a depth equal to at least[one-fourth] <br /> <Insert depth>of concrete thickness as follows: <br /> 1. Grooved Joints: Form control joints after initial floating by grooving and finishing each <br /> edge of joint to a radius of 1/8 inch. Repeat grooving of control joints after applying <br /> surface finishes. Eliminate groover tool marks on concrete surfaces. <br /> 2. Sawed Joints: Form control joints with power saws equipped with shatterproof abrasive or <br /> diamond-rimmed blades. Cut 1/8-inch-wide joints into concrete when cutting action does <br /> not tear, abrade, or otherwise damage surface and before concrete develops random <br /> cracks. <br /> D. Isolation Joints in Slabs-on-Ground: After removing formwork, install joint-filler strips at slab <br /> junctions with vertical surfaces, such as column pedestals, foundation walls, grade beams, and <br /> other locations, as indicated. <br /> 1. Extend joint-filler strips full width and depth of joint, terminating flush with finished <br /> concrete surface unless otherwise indicated on Drawings. <br /> 2. Terminate full-width joint-filler strips not less than 1/2 inch or more than 1 inch below <br /> finished concrete surface, where joint sealants, specified in Section 079200 "Joint <br /> Sealants," are indicated. <br /> 3. Install joint-filler strips in lengths as long as practicable. Where more than one length is <br /> required, lace or clip sections together. <br /> E. Doweled Joints: <br /> 1. Install dowel bars and support assemblies at joints where indicated on Drawings. <br /> 2. Lubricate or asphalt coat one-half of dowel bar length to prevent concrete bonding to one <br /> side of joint. <br /> F. Dowel Plates: Install dowel plates at joints where indicated on Drawings. <br /> 3.5 CONCRETE PLACEMENT <br /> A. Before placing concrete, verify that installation of formwork, reinforcement, and embedded <br /> items is complete and that required inspections are completed. <br /> B. Notify Architect and testing and inspection agencies 24 hours prior to commencement of <br /> concrete placement. <br /> C. Do not add water to concrete during delivery, at Project site, or during placement unless <br /> approved by Architect in writing, but not to exceed the amount indicated on the concrete <br /> delivery ticket. <br /> Orange County Solid Waste Drainage Repairs DAA 2200365/TRC 017055.0000.0000 <br /> Drainage Repair Project November 2023 <br /> Orange County, NC 033000-11/19 <br />
