The' Contractor shall be responsible for the strength and sufficiency of all sheeting and bracing. Should the Engineer decide that the sheeting and bracing at any point is inadequate or improperly constructed, he may order additional sheeting or bracing to be placed at the Contractor1s expense. Bracing shall be so arranged as to provide ample working space and so as not to interfere with the work and so as not to place any strain on the structures being constructed until such structures are" in the opinion of the Engineer, of ample strength to withstand such strain. All sheeting and bracing, unless othe~lise specified or ordered to be left in place by the Engineer" shall be installed and removed from the work at no additional compensation. No sheet- ing and bracing shall be removed until the construction has pro- ceeded far enough to provide ample strength in the opinion of the Engineers" Any damage to the work under this contract or to adjacent structures or property caused by settlement, water or earth pressures, slides" caves or other causes due to failure or lack of sheeting and brac- ing or improper bracing or tli-I'ough negligence or fault of the Contractor in any manner shall be repaired by the Contractor without delay at his expense. lNhere the trench is not located near eYisting utilities, buildings or other structures and. v,rhere v,rater and other conditions permit, the Contractor may with the approval of the Engineer, omit sheeting and bracing of the excavation. In this event, he shall excavate -8- sP-SS a space of sufficient size to provide adequate space for the con- struction work so as to prevent sliding or caving of the banks into the area within the lines of structures. The Contractor shall leave in place to be imbedded in the backfill of the trencn all sheeting and bracing etc., which the Engineer may- direct in writing to be left in place for which the Contractor shall be paid. In addition to that sheeting and bracing mentioned above, the Contractor may also leave in place, to be imbedded in the backfill of the trench, any sheeting and bracing which he nay consider necessary to prevent injury to persons, structures, corporations or property, whether private. or public, for which he assumes the entire and sole liability for any damage which may be caused by the installation, and for which he shall receive no payment or extra compensation. No sheeting and bracing vlhich is within 3 ft. of the surface of the ground may be left in place in the trench without written permission from the Engineer. When sheeting and bracing have been ordered left in place, pa}~ent for same shall include the upper 3 ft. or "cut-off" section of the sheetingo 14.

DJSTALLATION OF SANITARY Sm'iER AND APPURTENANCES Proper implements, tools and facilities satisfactory to the Engineer shall be provided and used by the Contractor for the safe and con- venient prosecution of the work. Pipe and other materials shall be unloaded and dlstributed on the job in a manner approved by the Engineer. In no case shall materials be thrown or dumped from the truck. All materials unloaded in an unsatisfactory manner shall be rejected and work shall be stopped until such materials have been examined by the Inspector and approved. The Contractor shall furnish the necessary assistance in such examination of materialso Sanitary sewer materials shall be carefully lowered into trench piece by piece by means of a derrick, ropes or other suitable tools or equipment, in such a manner as to prevent damage to materials and protective coatings and lining. Under no circumstances shall sanitary sewer materials be dumped into the trench. A. Laying and Bedding of Pipe and Fittings Before lowering and while suspended, the pipe shall be inspected for defects and rung with a light hammer to detect any cracks. Any defective, damaged or unsound pipe shall be rejected. All foreign matter or dirt shall be removed from the inside of t'le pipe before it is 10"V'rered into its position in the trench, and shall be kept clean by approved means during and after laying. All openings along the line of the sewer shall be securely closed as directed in the suspension of work at any time suitable stoppers shall be placed to prevent earth or other substances from entering the sewer. All pipe shall be bedded as per Class B bedding, unless otherwise directed by the Engineer. Class B is that method of bedding trench conduits in which the conduit is set on fine granular materials in an earth foundation carefully shaped to fit the lower part of the conduit exterior for a width of at least 60% of the conduit breadth4 The remainder of the conduit is entirely surrounded to a height of at least one foot above its top by granular materials carefully placed by hand to fill completely all spaces under and adjacent to the conduit. The fill is tamped thoroughl~l on each side and under the conduit as far as practicable In layers not exceeding six inches in thickness. In the event that suitable, fine granular and granular ma'erial lS not encountered during the normal excavation of the sewer trench or when the material encountered is determined unsuitable by the Engineer for backfilling around the conduit as required for Class B Bedding, the Contractor shall provide and place such approved material (sand fill) as required at no extra compensation. -10- SP -SS Pipe laying shall proceed upgrade with the tongue or spigot ends pointed in the direction of the flow. No pipe shall be laid in water or when the trench conditions are unsuitable for such work, except by permission of the Engineers. This Contractor shall make all of the connections of pipe to the manholes which have previously been constructed. He shall receive no extra compensation for connections. to capped stubs or cutting into present manholes. For completing drop sections for drop man- holes Contractor shall be paid as per unit price bid. Bo Jointing of Pipe and Fittings (1) Concrete Pipe The rubber gasket shall truly conform in size to the tongue end of the pipe and shall be cemented thereto with material suitable for this purpose so that it will be held firmly in place during the assembly of the pipeo The gasket shall be cemented to the tongue of the pipe not less than twelve (12) hours before the plpe is laid. Cement grout shall be one (1) part Portland Cement to two (2) parts clean sand, free of lumps, and mixed with sufficient water to make a pourable consistency of thick cream. Diapers shall be made from suitable fabric of sufficiently close weave to prevent the loss of cement from grout, but shall not be waterproof. Diapers shall be henmed on each edge, wi h a sceel i'lire or straps inserted ready for application. Cotton fabrlc diapers with round steel wire and 8 inch width shall be used on pipe of 33 inch loDe or smaller. Burlap fabric diapers with 3/8 inch steel straps and 9 inch width shall be used on pipe of 3b inch IoD" or larger. i1Jires shall be securely fastened by hvisting opposite ends together with pliers and straps shall be tightened ..'lith tension- ing tool and secure with a crimped seal. After a pipe has been laid, the trench bottom directly adjacent to the joint location shall be undercut to a width and a depth sufficient to allow for full expansion of the grout filled dia- per. The diaper shall then be secured to the bell or grooved end of the pipe in place by clinching one tie-wire or strap and the diaper folded back out of the way. After the spigot or tongue of the next pipe is properly in place and the pipe pulled home, the diaper lS pulled across to span the joint and the second tie-wire or strap is securely clinched around the barrel of the pipe just laid. The diaper shall be poured completely full of cement grout until the diaper becomes taut and convex around the entire circumference of the joint The pour shall be made from one side until the grout flows under the bottom and rises on the opposite side. The pour may then be completed from both sides. In hot dry weather, clear -11- SP -SS water may be poured into diaper to wet the pipe circu~ference prior to pouring the joint grout. No backfill shall be placed about the joint until the diaper is completely poured full of grout. The annular space inside the pipe shall also be filled with a relative stiff mortar mix of 'One (1) part Portland Cement to two (2) parts clean sand and the joint made smooth. (2) Clay Ph)e Flexible compression joints, as specified) shall be applied to clay pipe and fi ings at the factory and materials shall be ready for installation at the job site. lAThen installing clay pipe with the flexible compression joint, the bell and spigot surfaces should be cleaned of dirt and foreign matter. The surface of the joints should then be painted with a lubricant sealer. Position the top or one side of the spigot joint into the bell end of the pipe previously laid and push the pipe home. For larger diameter pipe~ a lever with a wooden cushion block, a shovel or a bar may be used to shove the joints in placeo The slight pressure used to shove the joints together contributes to the tightness of the joint because it keeps the precision mating surfaces in tight contact with each other and thus exerts a pressure on the inside of the bell and the outside of the spigot. (3) Cast Iron or Ductile Iron Pipe Cast iron pipe shall bej ointed \'lith mechanical joints using rubber gaskets. Jointing shall be done in accordance iiJith !1Notes on ))/[ethod of Installationtl included in A.S"A.

In addition to the blading and maintenance requirements specified under this article, the Contractor shall also be required to adequately control dust on the streets after compaction and grading when directed by the Engineer. When so directed by the Engineer, the Contractor shall provide one tank truck of adequate size with spray bar or other suitable quipment for sprinkling streets which shall be available at all tLes for street maintenance. If in the opinion of the Engineer, the Contractor is not maintaining adequate dust control with one tank truck, he shall provide additional tank trucks at no additional compensation. All deficiencies in the quantity of material for backfilling the trenches or for filling depressions caused by settlement shall be supplied by the Contractor. Any excess material shall be hauled a~'lay and dep.,sited i'lhere directed by the Engineer at no additional compensation. The Engineer shall determine ~\There excess material shall be hauled within the Village limits. The Contractor shall remedy at his own expense any defects that appear in the backfill for a period of one year following completion. When the trench excavation for the water main and appurtenances is within the right-of-ways of state or County, the backfilling of the trench, compaction of materials and sub-grade preparation shall be done in strict accordance with the existing requirements and specifications of the state or County Highway Department at no additional compensation. In all cases~ the Contractor shall blade the roadway after the trench has been backfilled, so that it shall be passable to traffic at all tilDes. The Contractor shall maintain the roadi-vay in a condition acceptable to the Engineer at all times until final acceptance 01 the entire work by the Village. Therefore, the Contractor shall provide one motor grader which shall be avail- able at the project at all times for surface maintenance. If in the opinion of the Engineer, the Contractor is not maintaining the street surfaces sufficiently with one motor grader, he shall pro- vide additional blades at no additional compensation. 180 TESTING AND DISINFECTING IvIAINS After the pipe has been laid including fittings~ valves, services and hydrants and the line has been backfilled in accordance with these specifications, all newly laid pipe, or any valved section thereof, unless otherwise directed by the Englneer, shall be subjected to hydrostatic pressure of 150 lbs. per sqo in. The duration of each such test shall be at least two hours. Water -17- SP -~vIVI added to maintain the pressure shall not exceed the volume per 100 lineal feet of pipe being tested during the two hour test as specified in the following table: Pipe Size Maximum Allowable Leakage in Gallons/100 ft. of Pipej2 Hour Test 6li 811 l211 l611 l8li 2411 0.5 gallon 0.7 gallon 1.0 gallon 1.3 gallon 1.5 gallon 2.0 gallon Each valved section of pipe shall be slowly filled with water and the specified test pressure, measured at the lowest point of elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. The pump~ pipe connection, gauges and all necessary apparatus shall be furnished by the Contractor. Gauges and measuring devices must meet with the approval of the Engineer and the necessary pipe taps made as directed. Before applying the specified test pressure~ all air shall be expelled from the pipe. To accomplish this, taps shall be made, if necessary, at points at highest elevations, and afte~~ard tightly plugged. Any cracked or defective pipes, fittings, valves or hydrants discovered in consequence of the pressure test shall be removed and replaced by the Contractor with sound material in the manner provided and the test shall be repeated until satisfactory to the Engineer. After the installation has been tested, the Contractor shall follow the disinfection procedures as described in paragraphs Nos. 1227 and No. 1228 of Section XII~ lIManual of ~vater Supply Sanitationll, of the Minnesota Department of Health. The Con- tractor shall become thoroughly informed on the requirements of the above mentioned manual and shall maintain a sufficient number of copies of same on the job site. Unless facilities are available for the introduction of either chlorine or heavily chlorinated water directly into the mains on their completion, chlorine disinfectant should be placed at each joint prior to jointing. The following table indicates the amount of calcium hypochlorite (65% available chlorine) that shall be added to each 16 ft. length of pipe to furnish a so- lution containing the minimum amount of free chlorine. -18- SP -i>Jr1 Pipe Size Calciu~ Hypochlorite (65% available chlorine) 611 81l 1211 161i l8il 24. i1 1/3 oZo 5/8 oZo 1=1/4 oz. 2=1/4 oz. 3-1/4 oz, 5 oz.
