Round frames and covers shall be of non -rocking design or shall have machined horizontal bearing surfaces to prevent rocking and rattling under traffic. All castings shall be fully interchangeable. 4. All weights shall not deviate from the tolerances permitted by ASTM A48-83 "Standard Specifications for Gray Iron as ngs . r_. �r 1(-' V Y 'r r y�� 5. Sanitary sewer frames and covers shall be type Neenah R1642 A 6. Joints - manhole sections shall be jointed with sealed 'o rings`) The "o" rings shall meet ASTM C-433 latest revisions. APPLICATION: A. Permits and Codes: The intent of this section of the specifications is 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 as amended by any waivers. Contractor shall fumish all bonds necessary to get permts for cuts and connections to existing sewers. B. Local Standards: The term "Local Standards" as used herein means the standards of design and construction of the respective municipal department or utility company, C, Existing Improvements: Maintain in operating condition all active utilities, sewers and other drains encountered in the sewer installation, Repair to the satisfaction of the owner any damage to existing active Improvements. D. Workmanship: To conform to all local, state and national codes and to be approved by all local and state agencies having jurisdiction. E. Trenching: Lay oil pipe in open trenches, except when the local authority gives written permission for tunneling. Open the trench sufficiently ahead of pipe -laying to reveal any obstructions. The width of the trench shall be the inside pipe diameter plus 24 inches for 12 inches above the pipe. Sheet and brace trench as necessary to protect workmen and adjacent structures. All trenching to comply with Occupational Safety and Health Administration Standards. Keep trenches free from water while construction is in progress. Under no circumstances lay pipe or appurtenances In standing water. Conduct the discharge from trench dewatering to drains or natural drainage channels. F. Special Supports: Whenever, in the opinion of the Engineer, the sell at or below the pipe grade i is unsuitable for supporting sewers and appurtenances specified in this section, such special support, in add tion to those shown or specified, shall be provided as the Engineer may direct and the contract will be adjusted. G. Backfilling: For a depth of at least 12 Inches above the top of the pipe, bockfill with granular material free from large stones, rock fragments, roots or sod. Compact this backftll thoroughly, taking care not to disturb the MIN t) TI.�P`•UIL R rTHAN GPONTH IF N_)T 1-_.

Manhole inverts: Construct manhole flow channels of concrete or sewer pipe. smoothed and eeml- clrcuiar section conforming to the inside diameter of the connecting sewers. Make changes in size or grade gradually and changes in direction by true curves. Provide such channels for all connecting sewers at each manhole. I. Infiltration: Fumish necessary equipment to test sewers for Infikrotion. Infiltration rates shall not exceed the local standards. All sanitary sewer lines upon completion will be required to pass a low pressure air test, unless otherwise directed by the City of Carmel Utilities. Infiltration under test shall not exceed 100 gallons per inch on inside diameter of sewer pipe per mile of sewer In 24 hours and inclusive of all appurtenances within the section being teeted such ars manholes, house connections, etc. J, Flushing Sewers: Flush all sanitary sewers except building sewery with water to obtain free flow through each line.
