APPLICATION: A. Permits and Codes: The intent of this section is the specifications if that the contractor's bid on the work covered herein shall be based upon the drawings and specifications but that the work shall comply with all applicable codes and regulations. Contractor shall furnish all necessary bonds to get permits for cuts and connections. B. Existing Improvements: Maintain in operating condition all active utilities and sewers F and other pipe system that may be encountered. C. Trenching: Lay all pipe in open trenches, except when local authority gives written permission for tunneling. Provide a separate trench for the water line at least 10 feet horizontally from any sanitary sewer. In locations where separate trenches for sewer and water lines are impracticable, lay the water pipe on a slid shelf at least 18 inches above the top of the sewer. D. Width of Trench: Excavate trenches minimum of pipe diameter plus 120 . E E Sheeting and bracing Sheet and brace trenches as necessary to protect workmen and adjacent structures. All trenching shall comply with the Occupational Safety and Health Administration Standards. F. Water Removal: Keep trenches free from water while construction therein is in progress. Under no circumstances lay pipe or appurtenances in standing water. Conduct the discharge from trench dewatering to (wins or natural drainage charnels. G. Grading Trench Bottoms: The bottom quadrant of the pipe shall be fully and uniformly supported. The full load shall rest on the barrel of the pipe. The trench may be excavated to a depth of 4 inches or more below find grade with sand, crushed stone or gravel backfill to bring it bade to pipe laying grade. For a depth of at least D 12 inches above the top of the pipe backfill with earth or granular material free from large stones, roots or frozen dogs. Tamp this backfill thoroughly taking care not to disturb the pipe. Badkfill under walks, parking areas, driveways and streets with granular material only and tamp thoroughly, by approved methods. Trenches parallel to and within 10 feet of paved roadways shall be constructed the sane. H. Tests: Before joints are covered, fill the piping with water, opening hydrants or at least two hours at a pressure of 100 pounds per square inch. Inspect all joints for leakage and remedy any leaks. Upon completion of the water distribution mains, flush out the system until the water runs clear. As soon as the system has been flushed out it shall be sterilized in accordance with the requirements of City of Carmel. C I. If a horizontal distance of 10 feet cannot be maintained between the water line and and a sanitary sewer line, one of the following shall be done. a. Water line laid in o separate trench and 18" above sewer. b. Water line laid in some trench on a bench of undisturbed earth and sewer at least 18" below bottom of water line. Where water lines and sewers cross and the water line cannot be placed above the sewer with a minimum of 18' vertical clearance, the sewer must be LID B constructed of water works grade cost iron pipe with mechanical joints within CD 10 feet of the water line. N J. Utfitkes: It shall be the responsibility of each contractor to verify all existing utilities m and conditions pertaining to his phase of the work. It shall also be the contractors r responsibility to contact the owners of the various utilities before work is started The contractor shall notify in writing the owners or the engineer of any changes, errors or M omissions found on these plans on in the field before work is started or resumed. K. New Water Main Construction: Contractor to record dimension of each water stub and ,i valves from nearest fire hydrant measured along water main. The locations of hydrants A and water valves, along with any other construction changes are to be incorporated on "Record M the original construction drawings and Drawing' prints submitted to Engineer's Office as soon after completion of construction as possible.
