That a local improve:ment shall be made within the Village of Mount Prospect, the nature, character, locality and description of which improvement is as follows I That sanitary sewers of 8-inch and 14-inch internal diameter be constructed and laid in Mount Prospect Road from twenty-five (25) feet south of the south line of Evergreen Ave. to a point twenty-eight (28) feet north of the north line of Lincoln St., and from twenty-two (22) feet south of south line of Lincoln St. to a point five hundred and forty-seven (547) feet south of south line of Lincoln St., and connect to and discharge into an existing Sanitary District of Chicago sewer of thirty (30) inch diameter located in Mount Prospect Road. Connections to the existing Sanitary District of Chicago sewer shall be made at the existing manhole on the east side of Mount Prospect Road at Milburn Avenue and at the existing manhole on the east side of Mount Prospect Road, approximately three hundred and ninety (390) feet south of the south line of Lincoln St. The proper locations and grades of said sanitary sewers are more fully described on the drawings attached hereto and by reference made a part hereof. SEWERS AND APPURTENANCES: Sewers shall be constructed of Cast Iron Pipe, and Standard Stren~ Vitrified Clay Pipe conforming to the following specifications and in accord- ance with detailed plans attached hereto. Standard Strength Vitrified Clay Pipe shall conform to the American Society for Testing Materials, Designation C-13. All pipe shall be smooth, straight and sound, thoroughly burned and vitrified, well glazed, free from lumps or other imperfections and with the least possible variation from the specified dimensions of true cylindrical shape. All straight pipe shall be straight in the direction of the axis of the cylinder and the inner and outer surfaces of each pipe shall be concentric. The standard minimum thickness of the shell of the clay pipe herein provided shall be eleven-sixteenths (11/16) of an inch for 8" standard strength vitrified Clay Pipe, ASTM C-l3. Joints between adjoining bell and spigot of the Vitrified Clay Pipe shall be made by fitting the sewer pipe with an approved die cast tapered type joint. This joint shall be made by fitting the spigot and socket of the pipe with collars of bituminous compound having a melting point of 240 degrees to 270 degrees F. A lining or ring of the bituminous compound shall be die cast into the socket of the pipe and around the spigot of the pipe, of such size and dimension that when the spigot is shoved firmly into the socket portion of the pipe, a tight fit between socket and spigot will be made. All pipe shall be dry and clean when joint lining and collars are cast. No pipe shall be used if either collar or lining shows any void or unfilled space. When laying the Vitrified Clay Pipes, the joint lining and collar shall first be painted with a bituminous solvent, which shall cause their surfaces to become plastic or sticky, and when the pipes are shoved firmly together -2- -1 the joint material shall unite and thus become thoroughly waterproof. All cast iron pipe herein provided shall be made of the best quality of cast iron, centrifugally cast in metal molds; minimum weights per lineal foot of pipe shall be as follows: Eight (8) inch internal diameter Fourteen (14) inch internal diameter 37.l/#/ft. 83 . 4/# I ft. Allowable variations in diameter and thickness, method of manu- facture, marking and coating shall conform to the U. S. Government Specification WW -P-42la, Class 150. Mechanical joint fittings shall be used throughout. The mechanical joint pipe shall be similar and equal to Super -de -Lavaud "C -N"Mechanical Joint Cast Iron Pipe, and shall conform in all respects to Federal Speci- fications mentioned hereinbefore. The joints shall be executed in accordance with manufacturer's recom- mendations, and bolts shall be tightened with approved torque wrench or other apporved means to secure uniform and allowable tension on the bolt. Sewer wyes for house connections shall be installed at all locations shown on the drawings, shall be of vitrified clay pipe, and shall be eight (8) inches by six (6) inches, and shall conform to the specifications for Vitrified Clay Pipe enumerated hereinbefore. The terminal end of each wye ('Y" branch shall be closed with a vitrified tile round disc one (1) inch in thickness. The disc or stopper shall be set in the bells of the wye ("Y") connection and shall be sealed into place with mortar of the kind and quality hereinafter specified for manhole construction. Manholes shall be forty-two (42) inch internal diameter, with curved concrete blocks five (5) inches in thickness and concrete floor and foundation -3- ",,1-,--- .. eight (8) inches in thicknesjl, lying directly below the invert of the largest sewer entering the manhole. The upper two and one-half (2 1/2) feet of said manholes shall be drawn in cone shape to an internal diameter of two (2) feet at the top by the use of concentric concrete rings or monolithic concrete construction, all as detailed on the attached plans. All sewers entering a manhole shall terminate at the inside face of the manhole. All manholes shall be equipped with a cast iron frame and cover, the combined weight of which shall not be less than three hundred and sixty- five (365) pounds. The tops of the covers shall be set at the elevation of the sumce of the adjacent ground. The curved concrete blocks used in manhole construction shall conform to the American Society for Testing Materials, Serial Designation C-139. The cement mortar used in the manholes orother purposes in this improvement shall be composed of one (1) part portland cement and two (2) parts clean torpedo sand, with 10% hydrated lime. BACKFILLING: The material used in backfilling the trench around the pipe and to a depth of twelve (12) inches over the top of it, shall be free from large stones. The backfilling shall be tamped in six (6) inch layers up to twelve (12) inches above the top of the pipe. CONCRETE: The portland cement concrete used in the construction of the man- hole structures shall be composed of the following materials: One (1) part portland cement and two (2) parts fine aggregate and three and one-half (3 1/2) parts of coarse aggregate with sufficient water added to produce a proper consistency. -4- Coarse aggregate shall consist of clean, hard, tough, durable crushed rock or pebbles, grades in size, free from vegetable or other deleterious matter, and shall contain no soft, flat or elongated pieces. The size of said crushed rock or pebbles shall be such as to pass atwo (2) inch round opening and shall range down so that no more than five (5) per cent shall pass a screen having four (4) meshes per lineal inch and so that no intermediate sizes shall be removed. Fine aggregate or sand shall consist of quartz particles or other equally hard material graded from fine to coarse, with the coarse particles predominating. Said fine aggregate when dried shall pass a screen having four (4) meshes per lineal inch. Not more than twenty (20) per cent shall pass a sieve having fifty (50) meshes per lineal inch and not more than eight (8) per cent shall pass a sieve having one hundred (100) meshes per lineal inch. Said fine aggregate shall contain no vegetable or other deleterious matter or more than three (3) per cent by weight of clay or loam. The cement shall be of a good grade of Portland cement which meets the latest requirement of the American Society for Testing Materials, and shall be a product re sulting from the calcination to incipient fusion of an intimate mixture of properly proportioned argillaceous and calcarous materials and to which no additions greater than three (3) per cent has been made subsequent to calcination. The resultant clinker shall be so grounp. as to produce a cement so fine that at least seventy-eight (78) per cent of the volume will pass through a sieve having forty ~housand (40,000) meshes to the square inch and be so seasoned as to produce initial set in not less than forty five (45) minutes. Mixing water shall be clean and shall be free from oil, acid and injurious amounts of ve getable matter, alkalie s or other salts. -5- The ingredients of the concrete shall be thoroughly mixed until each particle of fine aggregate is coated with cement and each particle of coarse aggregate is coated with mortar. A mechanical mixer shall be used which shall mix the ingredients at least one (1) minute, from the time all the materisla, including water, are in the drum until the beginning of the discharge. The consistency of the mixed concrete shall be such that no sepa- ration of the ingredients takes place in handling and some tamping is' necessary to bring the mortar to the surface. DRIVEWAYS & STREET PAVEMENT: The existing concrete, gravel and bituminous driveways and street pavement shall be removed at locations where the sewer construction necessitates such removal. The waste material so produced shall be re- moved from and disposed of off the site. The driveways and street pavement so removed shall be replaced with materials equivalent to the original materials and to the same width and thickness. In locations indicated on the drawings attached to this resolution or as ordered by the Engineer in writing during actual construction for purposes of safety, wood sheeting and bracing shall be left in place. Such sheeting and bracing shall be of sound timber. TRENCH BACKFILL: As directed by the Engineer, trenches caused by the construction of the sewers which fall beneath existing street pavement and driveways shall be backfilled with sand, screenings, pit run gravel, crushed stone or pea gravel from the spring line of the pipe to the finished sub-grade. The trench backfill shall be thoroughly "jetted" in a manner and with equipment satisfactory to the Engineer. -6- All materials of every kind and character to be used in the con- struction of this improvement shall be of first-class quality, suitable for the purpose for which they are to be used and subject to the inspection and approval of the Board of Local Improvements of the Village of Mount Prospect, Cook County, !llinoi s .
