701.1 Definition.
Whenever the term Engineer is used with respect to water main or water service lateral construction, it shall be understood to include the General Manager of the Madison Water Utility and all duly authorized representatives thereof.
Water main and water service lateral construction consists of excavating the required trenches and tunnels; laying the required pipe, fittings, special castings, valves, valve boxes, hydrants, structures and appurtenances; at the locations and to the required lines and grades; backfilling and compacting the trenches; and restoring the site of the work; all as shown on the drawings and provided by the Contract. The work consists essentially of the following items: 1. Making the necessary excavations, preparing the necessary foundations, inspecting materials, laying pipe, doing the necessary bracing, pumping, backfilling, compacting, installing polyethylene encasement, etc. Furnishing all tools, equipment, and material (except such as are specifically excepted herein) necessary for the laying in complete working order the mains and services described. Cutting pipes, making joints and all required connections, connecting bonding straps, providing concrete thrust blocking; setting and adjusting all valves, hydrants, and other appurtenances described in these Specifications. Making the tap, installation of corporation stops, laying of pipe, installation of curb stop and curb box or valve box, as required, and all compaction and backfill necessary to complete the installation of service laterals two (2) inches in diameter and smaller. Providing the ditch for the Water Utility to make the tap, setting valve box, laying the pipe, and all compaction and backfill necessary to complete pressure taps four (4) inches in diameter or larger. Repairing any and all damage caused to sewers, gas, telephone, or power facilities, or any other obstructions encountered in the prosecution of the work. Testing and disinfecting the mains. Backfilling and compacting trenches, clearing roads and grounds of all rubbish and refuse caused by the above work, resurfacing all gravel or stone roadways, and providing concrete and asphalt concrete street patches as directed.
Equipment and tools necessary for performing all parts of the work shall be satisfactory as to design, capacity, and mechanical condition for the purposes intended. Any equipment which is not
maintained in full working order, or which as used by the Contractor is inadequate to obtain the results prescribed, shall be repaired, improved, replaced or supplemented to obtain the progress and quality of work contemplated by the Contract.
On completion, the water main will undergo water quality testing and hydrostatic pressure testing. The water main may also be tested for electrical conductivity through the joints. Repair all defective work at no additional cost to the City.
Finishing Work and Maintenance.
Maintain all trenches in an acceptable and safe condition suitable for traffic throughout the work. At the completion of the work, the condition of all trenches shall be satisfactory to the Engineer. Repair all concrete, asphalt, and gravel pavements; stone flagging or paving; sidewalks, curbs and gutters; culverts; fences; or other structures damaged or displaced during construction. Surfaces shall be rebuilt or re-laid properly to the original line and grade in accordance with pertinent parts of these Specifications, or in the absence of applicable specifications, to original condition. Maintain all repaired, restored, or replaced asphalt and gravel surfaces until final acceptance of the project by the Common Council. Repair, restore or replace all failures occurring during the guarantee period at no additional cost to the City. Prior to final acceptance by the Engineer, clean and grade the project area. Unless otherwise provided, costs of the work included in this Article shall be included in the unit prices bid for the Contract items with which such work is associated. Final payment will be withheld until such work is completed in a manner satisfactory to the Engineer.
Unless noted otherwise herein, all pipe repairs shall be made by replacement of the defective pipe section with new pipe meeting these Specifications. Alignment, grade, bedding and backfilling shall conform to the requirements of these Specifications. Notify the Water Utility a minimum of twentyfour (24) hours prior to beginning any repair or replacement work, including the raising or facing of hydrants. Make all field cuts of all types of pipe with an approved mechanical pipe cutter or with a power saw in order to make a straight, true cut without chipping and cracking the pipe. For joining the replacement sections, use approved fittings conforming to the requirements of Section 702.6 and Section 702.8 of these Specifications. In no case will concrete encasement of defective pipe be allowed. These repairs shall include total and complete restoration of any disturbed surface to original or better than original condition, regardless of improvements on lands where the repair is required. Unless otherwise provided, the cost of the work included in this Article shall be included in the bid price.
