Submit record drawing with as-built plan and profile showing Texas State Plan <br /> <br />Coordinate NAD 27 grid and scale factor at both ends of the casing or change direction <br /> <br />of casing crossing. The vertical elevations at the end of the casing and any changes in <br /> <br />direction shall be tied to CW A's vertical data. As-built record drawing location and <br /> <br />coordinate values shall be provided to CW A at the conclusion of the project. <br /> <br />D. UNDERGROUND LINES. PIPELINES.

All underground lines, pipelines, conduits or cables installed above CW A's facilities, as <br /> <br />provided below, will be installed in steel casing extending the full width of CW A's right- <br /> <br />of-way. The casing will be coated, wrapped and electronically isolated from the carrier <br /> <br />pipe. Casing vents will be located outside of CW A's easements. <br /> <br />2. The bottom of the casing for any and all underground lines, pipelines, conduits or cables <br /> <br />to be installed above CW A's facilities will be placed so as to provide across the entire <br /> <br />~ <br />~! <br /> <br />width of the CW A right-of-way at least eighteen inches (18") of vertical clearance above <br /> <br />the top of the highest ofCW A's facilities. <br /> <br />3. All underground lines, pipelines, conduits or cables to be installed below CW A's <br /> <br />facilities per Section III and Section N with a minimum of three feet (3') of vertical <br /> <br />clearance between the top of casing and the bottom of the lowest of CW A's facilities. <br /> <br />4. Excavation for underground facilities shall be backfilled per Section III.F and Section <br /> <br />IV.E. <br /> <br />Page 8 ofl6 <br />
