9 C 2. SPECIAL PROVISIONS S-1 EXISTING MAINS AND SERVICES ACCIDENTAL DAMAGE: DALLAS WATER UTILITIES (DWU) DISPATCHER (214) All water and wastewater facilities must be protected during all phases of the construction operations. The Contractor is responsible for the cost to repair damage to existing water or wastewater main, water services, and/or wastewater laterals. Repairs will be made by DWU and the Contractor will be billed for the cost of the repair. The Contractor will not be permitted to make repairs unless authorized by the Engineer. Damage to other DWU facilities will be repaired by the Contractor, if repair is authorized by the Construction Engineer. If repair is not authorized by the Construction Engineer, the repair will be made by DWU and the Contractor will be billed for the cost of the repair. If such damage occurs the Contractor is to call the DWU dispatcher for repairs. THE CONTRACTOR IS NOT ALLOWED TO OPERATE WATER VALVES IN THE EXISTING SYSTEM. In the event of damage to a water facility that requires closing a water valve in the existing system, the Contractor must contact the DWU dispatcher. DWU personnel will shut off the valve. In the event a live water service is damaged or cut, the Contractor must immediately crimp the service to stop flow. IMMEDIATELY, the Contractor is to call the DWU dispatcher for repairs. PLANNED ALTERATION: If the Contractor plans to damage, cut, or alter the existing system in any manner, the means and methods must be approved by the DWU Construction Engineer. Any work done and materials used or disposed of, related to this item, shall be at no cost to the City. Also, if the DWU Construction Engineer disapproves any means or methods requested by the Contractor, this will not constitute the basis of any claim for additional costs to the City. The Construction Engineer shall have the authority to approve one or more of the following methods or other methods requested by the Contractor:

10 Temporary Main: If a temporary main is required to accomplish continuous water service, or if a temporary main is required to accomplish continuous wastewater service or if a wastewater pumping bypass operation is used, the work will be done by the Contractor at his expense. This shall include furnishing all labor, tools, materials, equipment, and incidentals necessary to complete the work, including all excavation and disposal of surplus material, transfer of services back to the existing system, and protection and repair of the temporary system. The means, methods, materials and size must be approved by the Engineer. Any wastewater pumping bypass operation must also be approved by the Engineer; including the size and type of pump. The Engineer will determine if a standby pump is required and if the pump(s) must be manned during non-working hours. Bullhead: Temporary services to several residences made off one existing service. Cut Water Service: The service shall not be intentionally cut if the resident or business proprietor objects to discontinued service. In no case will the service be cut for more than four (4) hours unless prior approval is obtained from the Construction Engineer and the resident or proprietor. The Contractor is responsible to coordinate this effort. Repair will be made by the method approved by the Construction Engineer. The methods shall be: 1. Remove the water service to a point one foot outside the ditch line on both sides. Use new copper pipe of the same size to replace the removed section. The connection nearest the main shall be made with a compression connection coupling. The connection nearest the meter will be made with a compression x compression curb stop or compression curb stop w/compression x O.S.I.P. coupling. 2. Install and connect a new copper pipe from the existing corporation cock on the main to the meter. Cut Wastewater Service: Repair shall be made as shown on Page G 4.1 of the Dallas Water Utilities Drawings, Details, & Standard Appurtenances for Water and Sanitary Sewer Construction Methods.

11 S-2 WATER AND WASTEWATER INFRASTRUCTURES AND APPURTENANCES Identified water and wastewater infrastructures will be altered, replaced, constructed and/or abandoned by the Contractor. Water and wastewater appurtenances encountered will be adjusted by the Contractor to permit construction and conform to the finished grades on the project. All materials and workmanship shall be in accordance with the North Central Texas Council of Governments Standard Specifications for Public Works Construction (NCTCOG), the DWU Addendum to the NCTCOG Specifications, DWU Drawings, Details & Standard Appurtenances, DWU Special Details, and the details shown on Paving Standard Drawing 251D-1. The work associated with water and wastewater facilities will be accomplished in generally three phases. Phase one will be accomplished in advance of grading operations which may include lowering existing appurtenances, repairing, lowering, or constructing portions of the existing water and/or wastewater mains, rebuilding laterals and/or water services to clear proposed storm sewer or other proposed facilities, relocating water services, meter boxes and meters, adjusting or constructing lateral cleanouts, constructing new laterals and/or water services that are in a deteriorated condition or constructed of a material that is identified to be replaced, and other work identified on the plans or outlined in the contract documents. Phase two will be accomplished prior to paving operations, which includes adjustment of appurtenances to the final paving grade. The last phase is the final inspection of the work to coincide with the final paving inspection. The unit price bid for each pay item will include all costs to bring the specified appurtenance to finished line and grade, set in permanent location, and being fully operational at the time of completion of the project. The contract unit price for each item will be full compensation for removal and salvage of the existing appurtenance, for all required cleaning before reinstallation, for all cutting or rebuilding necessary to match the finished grade of the paving or grading, for replacement of all damaged or lost parts, for protecting facilities to assist continuous and uninterrupted service, and for all material, labor, and equipment costs to satisfactorily complete the adjustments to the intent of the plans and specifications. All facilities must be completed to new construction standards in accordance with the NCTCOG Standard Specifications, and be fully operational at the time of final inspection of the completed project. The proposal price bid for pay items covered in this Special Provision for adjustment to water and wastewater appurtenances will not be subject to renegotiation due to quantity overrun or underrun limitations as set forth in Section of the NCTCOG Standard Specifications for Public Works Construction.
