BARBARA CATHOLIC SCHOOL TASK 2 75-24272-01 <br />DIOCESE OF ORANGE SEPTEMBER 12TH, 2024 <br />SANTA ANA, CA BID & PERMIT SET <br /> <br />STORM DRAINAGE 334100 - 8 <br />and other installation requirements. Maintain swab or drag in line and pull past each joint as it is <br />completed. Verify existing elevations prior to extensive excavating and notify Architect of any <br />discrepancies. Contractor shall be liable for any premature construction which must be <br />modified due to unforeseen existing conditions. <br />C. Install gravity-flow-systems piping at constant slope between points and elevations indicated. <br />Install straight piping runs at constant slope, not less than that specified, where slope is not <br />indicated. <br />D. Install proper size increasers, reducers, and couplings where different sizes or materials of pipes <br />and fittings are connected. Reducing size of piping in direction of flow is prohibited. <br />E. Install manholes for changes in direction if shown on plan, otherwise use fittings. Use fittings <br />for branch connections unless direct tap into existing storm drain is indicated. <br />F. Extend drainage piping and connect to building's storm drains, of sizes and in locations <br />indicated. Terminate piping as indicated. <br />G. Install gravity-flow, non-pressure drainage piping according to the following: <br />1. Install piping pitched down in direction of flow, at minimum slope of 1 percent, unless <br />otherwise indicated. <br />2. Install hub-and-spigot, cast-iron soil piping according to CISPI's "Cast Iron Soil Pipe and <br />Fittings Handbook." <br />3. Install PVC sewer piping according to ASTM D 2321 and ASTM F 1668. <br />4. Install Concrete Pipe and Fittings according to ACPA “Concrete Pipe Handbook” with <br />the following seals. Concrete round pipe and fittings per ASTM C443 (ASTM C443M), <br />rubber gaskets. Elliptical and Arch pipe: ASTM C877 (ATM C877M), Type I, sealing <br />bands. <br />H. Clear interior of piping and manholes of dirt and superfluous material as work progresses. <br />4.6 PIPE JOINT CONSTRUCTION <br />A. <br />A. General: Join and install pipe and fittings according to the following. <br /> <br />B. Install with top surfaces of components, except piping, flush with final finished surface. <br /> <br />C. Polyvinyl Chloride (PVC) Plastic Pipe and Fittings: As follows: <br />1. Join solvent-cement-joint pipe and fittings with solvent cement according to ASTM D <br />2855 and ASTM F 402. <br />2. Join pipe and gasketed fittings with elastomeric seals according to ASTM D 2321. <br />3. Join profile pipe and ribbed drain pipe and gasketed fittings with elastomeric seals ac- <br />cording to ASTM D 2321 and manufacturer's written instruction. <br />4. Install according to ASTM D 2321. <br /> <br />D. System Piping Joints: Make joints using system manufacturer's couplings, except where oth- <br />erwise specified.
