Whore excavation endangers adjacent structures and utilities, the Con- tractor shall at his own expense carefully support and protect all such structures and/or utilities so that there will be no failure or settlement. Where it is necessary to move services, poles, guy mires, pipe lines, or other obstruotions, the Contractor shall notify and cooperate with the utility owner, In case damage to an existing structure or utility occurs, whether failure or settlement, the Contractor shall isstoro the structure or utility to its original condition and position without compon,aation from the Owner. All costs of temporarily or permanently relocating the oonflioting utilities shall be borne by the Contractor without extra compensation from the Owner. If, in the opinion of the Engineer$ concrete backfill is necessary for the support of utility lines crossing trenches, the Engineer may direot '1500 lbs, concrete backfill be used.

Adequate care shall be take,. `o ineuro proper compaction under the pipe near the center of the trench. An an alternate to the above method of compaction, loose material may be placed in one operation from the bottom of trench to slightly above the pipe center line. This material shall then be compacted by use of water applied through a jet pipe. The water shall be applied under pressure and by forcing the jet pipe down into the material on each side of the pipe at close intervals so that the baokfill will be thoroughly saturated and will melt and flow under the pipe for its entire length. lbe apparatus for applying water for compaction by this method will be subject to the Engineer's approval to the extent that it must be oapabin of supplying water in suffi- cient quantlty and pressure to accomplish the desired result. The Contractor shall perform the jetting in such a manner to prevent floating the pipe. Any pipe which is floated or otherwise disturbed shall be relaid to the original grade at the Contractor's oxponno. 3• Li44kf,_,~].

The completed baokfill shall be compacted to such an extent that future settlement of the trench will be kept to a minimum. The compaction of the baokfill shall be at least 90% Procter density, and the Owner reserves the right to conduct density tests in order to determine compliance with this requirement. In the event backfill does not comply with this density requirement, the Contractor will be required to do such additional work as may be necessary in order to bring the compaction to within the limits not fo)Ah herein.

Adjustments as required shall be made for differential in elevation between the low point of the section being tested and center line of pressure test gauge, B. Duration of Tests The duration of each pressure test shall be four (4) hours. C, Procedure, The Contractor may test the concrete cylinder pipe line in sections when all the pipe in the section is at least 28 days old. Tho cast iron pipe line and/or the asbestos-ooment pipe line may be tested upon completion of backfilling and the "setting up" of concrete blocking. The test shall be made against valves when available, or by placing temporary bulkheads in the pipe, and filling the line slowly with water. Care shall be used to see that all air vents are open during the filling. After the line, or section thereof has been completely filled, it shall be allowed to stand under a slight proosure for at least 18 hours to allow the lining to absorb what water it will and to allow the escape of air from any air pockets. During this period the bulkheads, valves, manholes and oonnections shall be examined for leaks. If any are found these shall be stopped or, in the case of valves in the main line or bulkheads, provision shall be made ! for measuring the leakage during the test. The water necessary to maintain the test pressure shall, be measured through a motor or by other means satis- factory to the Engineer. Contractor shall furnish all neoessary equipment and make toots at his expense. Before applying the specified test pressure, all air shall be expelled from the pipe. En tho ovent it is necessary to oxpoll air from high points other than where air valves are provided, the Contractor may tap the lino for this purpose and afterwards tightly plug the tap. Those taps must be made by the pipe manufacturer. No extra comprnoation will be made for these taps. p. T:xaminationUnder Presgro; During the last two hours of the test, the entire route of the pipe line shill be inspected to locate any leaks or breaks. Any defective ,joints, cracked or defective pipe, fittings or valves discovered in consequence of this pressure test shall be removed and replaced with sound material in the manner provided atxl the test shall be repeated until, satisfactory results are obtained. Any and all noticeable leaks shall be repaired regardless of whether the actual leakage is within the allowable. 113..1 Pormissible Leakage: No pipe installation will be aooepted until or unless the leakage, as determined by this Hydrostatia 'Pont, is within the allowances set forth in the tabulation below; Pipe Size Allowable Leakage par 100 Joints Gallons »sr hour 2" 133 4" 2.65 6" 3.97 8" 5,30 10" 6.62 12" 7,94 ib'' 10,59 18" 11.92 201? 13,24 F.
