G.7.2. Prosecution of the Work: The Contractor shall begin the work to be performed under this contract within the time limit stated in these specifications, and shall conduct the work in such a manner and with sufficient equipment, materials, and labor as is necessary to insure its completion within the time ~ limit.

G.7.4. Time and Order of Completion: It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Contractor shall be allowed to prosecute his work at such time and .-~ seasons, in such order of precedence, and in such a manner as shall be most conducive to economy of construction; provided, however, that the order and the time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and _ specifications, and within the time of completion designated in the proposal; provided, also, that when the City is having other work done, either by contract or by its own force, the Engineer may direct the G-18 timing of the contract, so that conflict will be avoided and the construction of the various works being done for the City shall be harmonized.

The sum of money thus deducted for such delay, failure or noncompletion is not to be considered as a penalty, but shall be deemed, taken and treated as reasonable liquidated damages, since it would be impracticable and extremely difficult to fix the actual damages. The Contractor shall also indemnify and hold the City harmless including paying court costs and defense fees from any property damage claims resulting from restriction of access caused by the Contractor's negligent performance or undue delay.

A "Major Item" shall be construed to be an individual bid item incurred in the proposal that has a total cost equal to or greater then five (5) percent of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices.

G.8.5.

END OF SECTION 03301-1 12/91 SECTION 15042 WATER PIPE TEST PART 1 - GENERAL 1. I. DESCRIPTION The work as specified in this section shall consist of the sterilizing and testing of all water piping installed on this project. 1.2. MEASUREMENT AND PAYMENT -- No separate payment will be made for any items of work, materials, parts, equipment, supplies, or related items required to perform and complete the requirements of this section. The costs for all such items required shall be included in the applicable bid item for the installation for the proposed water line. PART 2 - HYDROSTATIC TEST - Before final acceptance by the City of Irving, all water lines shall be filled with water from the distribution system of Dallas Water Utilities and examined for leakage. Any leaks occurring must be repaired and left in an absolutely tight condition before acceptance by the City. In the event the Contractor elects to backfill the ditch before the pipes are filled with water and tested, he shall apply a hydraulic test pressure of not less than 200 pounds per square inch, and maintain same over a continuous period of not less than four hours. He shall furnish adequate and satisfactory equipment and supplies necessary to make such hydrostatic test. Accurate measurement of the water added to the lines during the test shall be made and if the tests indicate a leakage in excess of a rate equal to fifty gallons per inch of nominal diameter of pipe per mile over 24 hours, then the Contractor shall locate the leaks and eliminate them. 2.2. STERILIZATION OF WATER LINES AND FITTINGS The Contractor shall sterilize all gaskets, pipe lines and appurtenances installed by him before they are put into services. Sterilization shall be done in the following manner: All gasket materials shall be dipped in a strong solution of HTH, or similar chlorine compound solution just before use in the pipe. Prior to chlorination, the main shall be flushed as thoroughly as possible with the water pressure from outlets available. Each valved section of newly laid pipe shall be flushed independently. This shall be done after the pressure test and may be done either before or after the trench has been backfilled. Methods: I Chlorine Liquid or Gas 2 Hypochlorite Solution ~- 3 Dry Hypochlorite 1. A chlorine gas-water mixture shall be applied by means of a solution-feed chlorinating device or, if -- approved by the Engineer, the dry gas may be fed directly through proper devices for regulating the rate of flow and providing effective diffusion of the gas into the water within the pipe being treated. 15042-1 4/92 Chlorinating devices for feeding solutions of the chlorine gas or the gas itself must provide means of preventing the backflow of water into the chlorine cylinder. 2. On approval by the Engineer, a mixture of water and chlorine-bearing compound of known chlorine content may be substituted as an alternate for liquid chlorine. The point of application for methods 1 and 2 shall be at the point of filling of the pipeline extension, or any valved section of it, and through a corporation stop inserted in the top of the newly laid pipe. The water injector for delivering the chlorine-beating solution into the pipe should be supplied from a tap on the pressure side of the gate valve controlling the flow into the pipeline extension. 3. As a joint &clean pipe is laid and just prior to the laying of the succeeding joint a measured amount of HTH or equal shall be placed in the joint with a spoon. When new lines are ready for the water test, they shall be filled very slowly so as not to wash the chlorine compound to one end of the newly laid line. The strength of the chlorine mixture in the pipe line shall be such that, after filling, it shall test at least 50 part per million. The solution shall remain in the pipeline for at least 6 hours. At the end of the 6 hour period, if it does not test 10 PPM, it shall remain in the line an additional hour for each part below 10 PPM. Where existing mains are cut, when that portion is put back or reconnected, it shall be treated with a strong solution of HTH or equal. 15042-2 4/92 I I ~ I I i I I I ~ I ~ !
