Pipe and other materials shall be loaded and unloaded by lifting with hoists or skidding so as to avoid shock or damage. Under no circumstances shall such materials be dropped. Pipe handled on skidways shall not be skidded or rolled against pipe already on the ground.

Sewage, surface and flood flows. The applicant shall furnish all the necessary equipment, shall take all necessary precautions and shall assume the entire cost of handling any water from leakage or breaks of existing mains, sewage, seepage, storm, surface and flood flows which may be encountered at any time during the construction of the work. The manner of providing for these flows shall meet with the approval of the engineer.

Provisions for public safety.

To protect from injury and to avoid property damage, adequate barricades, construction signs, torches, warning lights and guards as required shall be placed and maintained during the progress of the construction work until the site is safe for public use. Whenever necessary, watchmen shall be provided to prevent accidents. Rules and regulations of the local authorities regarding safety provisions shall be observed.

Excavations shall be conducted to cause the least interruption to traffic. If so directed by the engineer, the applicant shall provide suitable bridges at street and driveway crossings where traffic must cross open trenches. Hydrants under pressure, valve pit covers, valve boxes, curb stop boxes, fire or police call boxes or other utility controls shall be unobstructed and accessible during the construction period.

Alignment and grade. All construction shall conform to the required lines and grades. No deviation shall be made from the required line or grade except with the written consent of the engineer. Wherever obstructions not shown on the approved plans are encountered during the progress of the work and interfere to such an extent that an alteration of the line and/or grade is required, the engineer shall have the authority to order a deviation from the line and grade. If the change in line and/or grade results in work beyond that required by the approved plans, the cost for such additional work shall be at the expense of the applicant. Deviation from the lines and grades shown on the approved plans or established by the engineer shall be corrected at the expense of the applicant.

Trenches and other excavations.

The trenches and other excavations shall be of sufficient width and depth at all points to allow all pipes to be laid, joints to be formed and structures and appurtenant construction to be built in the most thorough and workmanlike manner, and to allow for sheeting and shoring, pulling and draining, and for removing and replacing any materials unsuitable for foundations. The trenches and excavations shall be at least eighteen (18) inches wider than the outside dimensions of the structures they are to contain. The maximum clear width of the trench one (1) foot above the top of the pipe shall be as shown on the approved plans. Greater width of the trench shall be permitted only upon approval of the engineer.

The depth of the trench shall be such that the pipe, when laid on the prepared bed, shall have at least five (5) feet of cover from the top of the pipe to the finished surface grade, unless shown otherwise on the approved plans.

The excavation for the trench shall be carried out at least four (4) inches and not more than six (6) inches below the specified bottom of the pipe. Before the pipe is laid, the trench shall be backfilled to subgrade by backfilling with an approved material, meeting the requirements of § 165-6C(1), Selected material for trench bottom, in four-inch to six-inch compacted layers. The layers shall be thoroughly tamped as directed by the engineer so as to provide a uniform and continuous bearing and support for the pipe. If the bottom of any excavation has been removed below the six-inch limit without authorization by the engineer, it shall be filled with an approved material and thoroughly compacted as directed by the engineer, at the applicant's expense. The subgrade elevation for pipe shall be fifteen percent (15%) of the outside diameter of the pipe above the pipe invert elevation, unless otherwise shown on the approved plans, to ensure that the bottom quadrant of the pipe barrel is embedded in the backfilled material. Hand tools shall be used to prepare the subgrade in the areas of the pipe bell.

Excavation in poor soil and refilling to subgrade. Where the bottom of the excavation is found to be unstable or to include ashes, cinders, all types of refuse, vegetable or other organic material which, in the judgment of the engineer, should be removed, the applicant shall excavate and remove such unsuitable material to the width and depth ordered by the engineer. The subgrade shall then be made by backfilling with an approved material meeting the requirements § 165-6C(1), Selected material for trench bottom, in six-inch compacted layers. The layers shall be thoroughly tamped as directed by the engineer so as to provide a uniform and continuous bearing and support for the pipe and/or structure. The finished subgrade shall be prepared accurately by means of hand tools.

Special foundation in poor soil. Where the bottom of the excavation at subgrade is found to consist of material which is unstable to such a degree that, in the opinion of the engineer, it cannot be removed and replaced with an improved material thoroughly compacted in place to support the pipe or structure properly, the applicant shall construct a foundation for the pipe or structure consisting of pilings, timbers or other materials, in accordance with plans submitted by the applicant and approved by the engineer.

Rock excavation.

The word "rock," wherever used as the name of an excavated material, shall mean solid ledge rock, masonry, concrete and boulders which, in the opinion of the engineer, require for removal drilling and blasting, wedging, sledging or barring or breaking up with a power-operated hand tool.

Rock shall be removed to provide a clearance of at least six (6) inches below and nine (9) inches on each side of all pipes, fittings, manholes and special structures.

The specified minimum clearances are the minimum clear distances which will be permitted between any part of the pipe and appurtenances being laid or structures being built and any part, projection or point of such rock, boulder or stone.

Where excavation is made in rock or boulders and the clearance specified above is provided, the subgrade shall be made by backfilling with an approved material meeting the requirements of § 165-6C(1), Selected material for trench bottom, in six-inch compacted layers at the applicant's expense. The layers shall be thoroughly tamped as directed by the engineer so as to provide for the pipe and/or structures. The finished subgrade shall be prepared accurately by means of hand tools.

The hours of blasting shall be fixed by the village. Any damage caused by blasting shall be repaired by the applicant at his expense. The applicant's procedures and methods of blasting shall conform to all laws and municipal ordinances pertaining to blasting for this work.

The code of the Association of General Contractors, the American Manual of Accident Prevention in Construction, must be followed. The applicant, in addition to observing all laws and ordinances relating to the storage and handling of the explosives, shall also conform to any further regulations which the engineer may deem necessary in this respect.

When rock is removed by blasting, it shall be removed at least thirty (30) feet in advance of the laying of pipe or construction of structures. When an existing pipe, conduit or structure intersects or comes within five (5) feet in the clear, on each side of the existing pipe, conduit or structure shall, in all cases, be removed with the utmost care to avoid disturbing the existing pipe, conduit or structure. If the applicant elects to blast, only the lightest of possible explosive charges shall be used. The applicant shall, in all cases, be held responsible for and shall make good any damage caused by blasting, accidental explosions or other rock removal procedures used.

Material from rock excavations may be used as backfill only in conformance with the following requirements:

The backfill shall not contain stones or rock more than four (4) inches in their largest dimension, and backfill shall not contain more than thirty-three percent (33%) rock.

All rock shall be uniformly distributed throughout the backfill. Nesting of rocks will not be permitted.

Material from rock excavations is not suitable for backfill and shall be removed from the site.

Excavation methods.

The use of trench-digging machinery will be permitted except where its operation will cause damage to trees, buildings or existing structures above or below the ground. At such locations, hand methods shall be employed to avoid such damage. Trenches shall be opened at such times and to such extent only as may be permitted by the engineer.

Where, in the opinion of the engineer, field conditions do not satisfactorily permit the use of large excavation equipment, the engineer shall have the right to limit the maximum size or equipment to be used by the applicant.

The applicant shall furnish, put in place and maintain such sheeting, shoring and bracing as may be required by all governing state laws and municipal ordinances and as may be necessary to protect life, property or the work. The engineer may order additional, longer or stronger sheeting, shoring and bracing or different methods where in his opinion the sheeting, shoring and bracing is not satisfactory. Any omission on the part of the engineer to so order shall not relieve the applicant of his responsibility to provide adequate sheeting, shoring and bracing. When close sheeting is required, it shall be so driven as to prevent adjacent soil from entering the trench either below or through such sheeting. Bracing, shoring and sheeting shall be securely fastened in place so they cannot loosen up and fall or move from position. All expenses for this work shall be paid for by the applicant.

Where sheeting and bracing are used, the trench width shall not be less than eighteen (18) inches or one (1) foot greater than the outside diameter of the pipe, whichever is greater.

The sheeting, shoring, bracing, etc., or parts thereof, shall be left in place after the completion of the work in locations where ordered, in writing, by the engineer. The engineer may require that at intervals the sheeting shall be left in place and that other sheeting be removed. All sheeting which is left in place, whether ordered by the engineer or left for the convenience of or to subserve the interests of the applicant, shall be cut off at least three (3) feet below the established finished grade or the existing surface of the ground, whichever is lower.

Failure to order sheeting left in place by the engineer shall not relieve the applicant from any responsibility for any loss or danger whatsoever from his lack of leaving sheeting in place on his own initiative.

Sheeting, shoring and bracing, except that which has been permitted or ordered to be left in place, may be removed after backfilling has been brought up to such an elevation as to permit its safe removal. As backfill is placed and if sheeting is to be withdrawn, the voids left by the withdrawn sheeting, shoring and bracing shall be filled and compacted.

The applicant shall at all times provide ample means and equipment with which to promptly remove and dispose of all water and drainage entering the excavation or other parts of the work and to keep such excavation dry until the pipeline and/or structure to be built therein is completed. In no case will the laying of pipe or building of structures be permitted with water in the excavation.

(9)

Dewatering methods and equipment shall be adequate to properly dewater the work and shall be subject to the approval of the engineer, and all water removed from the work shall be disposed of in an approved manner without damage to adjacent property or other work.

(10)

No tunneling will be permitted in place of open trench excavation unless specifically authorized by the engineer.

(11)

All surface materials which, in the opinion of the engineer, are suitable for reuse in restoring the surface shall be kept separate from the general excavation materials, directed by the engineer. All excavated material shall be piled in a manner that will not endanger the work or limit free access to any part of the work. Gutters shall be kept clean or other satisfactory provisions shall be made for street and other drainage. Precautions shall be taken to maintain access to all valve boxes, manholes and fire hydrants. Excess material shall be disposed of by the applicant at his expense.

Pipe laying.

Proper implements, tools and facilities satisfactory to the engineer shall be provided and used by the applicant for the safe and convenient prosecution of the work. All pipe shall be carefully lowered into the 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 the materials and protective coatings or linings. Under no circumstances shall materials be dropped or dumped into the trench. Pipe and fittings shall be carefully cleaned with a dry cloth to remove all sand, mud, clay, oil or ice so as to be left clean and dry. Every precaution shall be taken to prevent foreign material from entering the pipe while it is being placed in the line. During the laying operations, no debris, tools, clothing or other materials shall be placed in the pipe. At other times, the pipe shall be closed by a watertight plug or other means approved by the engineer. This provision shall apply during the noon hour as well as overnight. If water is in the trench, the seal shall remain in place until the trench is pumped completely dry. No pipe shall be laid in water or when, in the opinion of the engineer, trench conditions are unsuitable.

All pipe shall be laid uphill with the bell, socket or coupling ends facing the direction of laying. Preparation of the trench bottom and placement of the pipe shall be carefully made so that, when in final position, the pipe is true to line and grade, carefully centered, with a uniform invert.

Bedding of pipe. The pipe shall be bedded as shown on the approved plans or as directed by the engineer, in accordance with the following requirements:

Bedding on selected material. Unless otherwise shown on the approved plans or permitted by the engineer, the bottom of the trench, after the selected material for the trench bottom has been placed and compacted, shall be shaped to receive the bottom quadrant of the pipe barrel. In addition, bell holes shall be excavated so that after placement only the barrel of the pipe received uniform bearing pressure from the trench bottom.

Concrete encasement. Pipes encased in concrete shall be temporarily supported, by means of precast or poured-in-place concrete blocks or bricks, on the prepared bottom of the trench or excavation. Temporary supports shall have minimum dimensions and shall support the pipe at not more than two (2) locations, one (1) adjacent to each end of each length of pipe. For pipe encasement, sufficient concrete shall be used so that the encasement is at least four (4) inches thick at all points. The concrete shall be of such consistency as to permit its flow, without excessive rodding, to all required points around the pipe surface. The placing of the concrete shall be done in such a manner that the grade and alignment of the pipe will not be disturbed. Special provisions shall be taken to prevent flotation of the pipe during placement of the concrete.

Jointing.

In general, the method and materials to be used in jointing the pipe shall follow the recommendations of the pipe manufacturer. Prior to the start of the work, pipe layers shall be instructed by a representative of the pipe manufacturer in the proper method to be used, and the applicant will see that these methods are followed.

Preparatory to making the pipe joints, all surfaces of the portions of the pipe to be jointed or of the factory-made jointing material shall be clean and dry. No jointing of the pipes will be permitted in a wet trench or other excavation. Gaskets, lubricants, primers, adhesives, etc., shall be installed and used as recommended by the pipe or joint manufacturer's specifications. Gaskets and other jointing material shall be protected from damage at all times. Gaskets and jointing materials shall be inspected before installation of the pipe, and any loose or improperly affixed gaskets and jointing materials shall be removed and replaced to the satisfaction of the engineer. The pipe shall be aligned with the previously installed pipe, and the joint put together. Immediately after the pipes are put together, the position of each gasket and joint shall be inspected to be sure that the joint has been properly made and is tight. If, while making the joint, the gasket or jointing material becomes loose or misplaced, the pipe shall be removed and the joint remade to the satisfaction of the engineer.

The joints shall be made in a workmanlike manner so as to obtain the degree of watertightness required.

If a pipe joint is made by pushing against the opposite end of the entering pipe, using a metal bar or other means, the end of the pipe shall be protected with a block of wood to distribute the stresses and prevent damage to the pipe.

Setting valves.

Valves shall be located and set where shown on the approved plans. Valve clusters at intersections shall be set symmetrically and as close together as is practical.

Valves and boxes shall each be set and maintained in vertical positions. The position of the nut inside the box shall be such that free and complete access to the nut can be achieved with the wrench.

The finished elevation of the top of the valve box shall be such that the top is level with the surrounding pavement. In the case of incompleted streets or roads, the upper box section shall be set as close as possible to the theoretical grade of the finished street surface and the valve or valve cluster protected by barricade, barrels or other markers satisfactory to the engineer.

Hydrants.

Hydrants shall be located and set approximately where shown on the approved plans or as ordered and directed by the engineer. Hydrants shall be connected to the main by the necessary length of six-inch ductile iron pipe. All joints shall be mechanical joints with retainer glands installed in accordance with the manufacturer's instructions. Hydrant valves shall be located as shown on the typical section on the approved plans or two (2) feet six (6) inches from the hydrant center line.

The hydrant shall be set on a solid base, taking care to keep the drain hole unobstructed. The remainder of the base shall be packed with coarse gravel or crushed stone to permit drainage of the hydrant barrel.

The hydrant shall be so placed that the distance from the nut of the pumper connection to the finished ground elevation shall be eighteen (18) inches to twenty-one (21) inches. Extension sections shall be used only where unknown or unusual field conditions are encountered. The applicant shall provide hydrants with various depths of bury so that the hydrants may be installed to the proper elevation without extensions.

Service connections.

Services shall be installed in conformance with the requirements heretofore specified for excavation, pipe laying, bedding of pipe, jointing, backfilling and testing and/or in conformance with local municipal plumbing codes.

The minimum cover for service pipes shall be four (4) feet six (6) inches unless shown otherwise on the approved plans.

The service pipe shall terminate with a curb stop and box which shall be set so that the top of the box will be four (4) inches to six (6) inches above finished grade and adjacent to the user's property line. The curb box shall be adjustable to the flush position.

Before backfilling, the corporation stop shall be turned to the on position.

Service pipes and appurtenances shall be included in and subject to the hereinafter-specified test for pressure, leakage and contamination.

Backfilling.

Upon completion of the laying of pipe, backfilling will be started immediately and shall be continued so that at the end of the working day all pipe is completely backfilled. Selected materials for the trench bottom shall be placed continuously by hand in layers not exceeding six (6) inches in thickness after compaction and thoroughly consolidated by tamping simultaneously on both sides of the pipe to a minimum height of twelve (12) inches above the top of the pipe and to such additional height as may be shown on the approved plans.

The remainder of the trench shall be backfilled to the full height of the trench or to the elevations shown on the approved plans as follows:

Where trenches and other excavation are located in roadways, sidewalks or driveways or under curbing or other utilities, the backfill shall consist of run-of-trench materials placed in layers not to exceed twelve (12) inches and compacted by mechanical tampers. The top twelve (12) inches of the backfill shall be gravel fill meeting the requirements hereinbefore specified. If, in the opinion of the engineer, the trench materials are not usable as compatible backfill, on his order, it shall be disposed of and the backfill made in part or entirely with gravel fill compacted as described above.

At all other locations, unless specifically shown or required otherwise by the approved plans, the backfill shall be made as above, except that the top twelve (12) inches of backfill shall be similar to that excavated unless ordered otherwise by the engineer.

The surfaces of all backfilled areas shall be maintained through final consolidation so that the backfilled areas remain consistently on grade with the surrounding undisturbed surfaces.

Where shown on the approved plans, the applicant shall place fill to form a protective embankment over the pipe. This fill shall conform to the dimensions and elevations shown on the approved plans.

Any deficiency in the quantity of material for backfilling the trenches or construction embankments over the pipe or filling any depressions caused by settlement shall be supplied by the applicant at his own expense. Backfill material in rock excavations shall be included in this category. The applicant shall not permit the excavated trench or any portion thereof to be used for disposal of rubbish, and all backfill shall be free from cinders, ashes, organic material or other material which, in the opinion of the engineer, is unsuitable.

Backfilling around appurtenances and special structures shall be made as specified above for pipe. No backfill shall be placed against masonry structures until, in the opinion of the engineer, the concrete or mortar has had sufficient time to harden and cure. Backfill shall be placed evenly to the same height on all sides of the structure in order to avoid unbalanced lateral loading on the structure.

Backfilling shall not be done in freezing weather except by permission of the engineer, and it shall not be made with frozen material. No backfill shall be made where the material already in the trench is frozen. Compaction of all backfill and fills shall be completed to the full satisfaction of the engineer.

The specifications for backfill as detailed above are considered to be minimum. The applicant shall assume full responsibility for the preservation of the work and the structural integrity of the pipe and appurtenances. He shall also assume full responsibility for trench settlement during the construction period and the guaranty period. In the event of trench settlement, he shall do the required backfill, grading and/or replacement of paving to restore the prescribed surface elevations.

Testing.

During the progress of construction and/or upon completion of the same, pressure, leakage and disinfection tests shall be made on the pipe and appurtenances.

Pressure and leakage tests shall be performed on sections between valves of not more than one thousand five hundred (1,500) feet in length. All equipment and labor for the hydrostatic test will be provided by the applicant. Tests will be made at average pressure of one hundred fifty (150) pounds per square inch for a duration of two (2) hours unless otherwise ordered by the engineer.

Allowable leakage shall be determined by the formula:

	L	=	SD/P
			133,200
Where:
	L	=	allowable leakage in gallons per ur. ho
	S	=	length of pipe tested.
	D .	=	nominal diameter of pipe inches
	P	=	average test pressure during leakage test in pounds-per-square-inch gauge.

The section to be tested shall be slowly filled with water and the specified pressure applied by pump. Air shall be expelled from the pipe through user services or hydrants or through taps made as may be necessary by the applicant.

The section under initial specified pressure shall be allowed to sit for a period of two (2) hours or as ordered by the engineer. At no time during the test period shall the pressure be allowed to diminish by more than five (5) pounds per square inch from the initial pressure. In the event that the pressure is reduced by more than five (5) pounds per square inch, the line shall immediately be repumped to the initial pressure. At the end of the period or periods, the pressure shall be restored to the initial pressure, and the amount of water necessary to do so shall be measured to determine the leakage each time the line is repumped. The total water used during the two-hour test shall determine the leakage.

Pressure tests shall be made after the backfill is completed.

All parts of the work, including hydrants and user services, shall be included in the pressure, leakage and disinfection tests.

Before being placed in service and before certification of completion by the engineer, the entire work shall be disinfected in accordance with the methods prescribed in the AWWA Standard C-606 and/or as follows:

A disinfectant mixture which will provide fifty (50) parts per million minimum available chlorine shall be introduced into the system and retained for at least twenty-four (24) hours. The system shall then be drained and flushed. Bacteriological examination of the water samples, collected after disinfection, shall be made by a laboratory certified to conduct such tests by the New York State Department of Health, at the applicant's expense. Samples shall be taken at various points on the system as determined by the Village Engineer. If examination determines that the water is unfit for consumption, the disinfection process shall be repeated until potable samples are achieved.

(9)

The applicant shall furnish at his own expense an adequate supply of all water required during the construction and testing of the system, paying for the expenses and charges for the same, and installing and paying for a meter if it is required. When work is completed, temporary water connections and fixtures shall be removed by the applicant and all unused taps shall be plugged.

Cleaning up.

As the work progresses, the applicant shall clean up the streets and rights-of-way, and the backfill shall be rounded within the limits of the excavation. Soft trenches shall be marked and protected with signs and adequate lights, and subsequent settlement shall be promptly refilled.

All backfilled trenches and surrounding areas of work in progress shall be maintained as clean and dust-free as practical, as determined by the engineer. Water, calcium chloride, mechanical sweepers or other means as may be required shall be employed by the applicant to satisfy the engineer.

If within three (3) days, upon receiving a written notice from the village or the engineer, the applicant has not met the conditions of Subsection R(2) above, the village may clean, wet down, sweep, etc., the areas involved and backcharge the applicant.

Upon the completion of the work, all dirt and rubbish shall be hauled to a dump provided by the applicant and the construction site left clean to the satisfaction of the engineer. All surplus materials furnished by the applicant and all tools and temporary structures shall be removed from the site by the applicant.

Restoration and maintenance of pavement, damaged surfaces and property.

The applicant shall restore or replace all removed or damaged paving, curbing, sidewalks, gutters, shrubbery, grass, fences, sod or other disturbed surfaces or structures in a condition equal to that before the work began and to the satisfaction of the engineer and shall furnish all labor and material incidental thereto. In restoring improved surfaces, new pavement shall be laid, except that granite paving blocks, sound brick or sound concrete paving blocks may be reused.

Pavement replacement shall be made in accordance with the requirements of other sections of the approved plans and in accordance with the specifications and directions of state, county or village authorities having jurisdiction over the pavement.
