CC RESOLUTION 9RESOLUTION NO. A RESOLUTION OF THE BOARD OF TRUSTEES OF THE CITY OF EL SEGUNDO, CALIFORNIA, ADOPTING SPECIFICATIONS NUJMR ONE FOR THE GRADING, SURFACING AND IMPROVING OF STREETS WITHIN SAID CITY. BE IT RESOLVED by the Board of Trustees of the City of E1 Segundo, California, that the following specifications, to be known as Specifications Number One, for the grading, surfacing and improving of public streets in the said City of E1 Segundo, be and the same are hereby adopted, SECTION 1. The work herein provided for is to be done in accordance with the plans, profiles and cross- sections on file in the office of the City Engineer of the City of E1 Segundo, and all work shall during its pro- % gross and on its completion conform to the lines and levels which may from time to time be given by said City Engineer. SECTION 2. GRADING: Grading will include the construction of all embankments and excavations irrespeot- ive of the nature of the material encountered, required for the construction of any roadway, sidewalks, ourbs, gutters, waterways and ditches, borrow -pits, road and driveway in- tersections, foundation pits for culverts and other struct- ures, changing of streams and highways, and all other grading incidental to the construction of the finished im- provement. All grading shall be true to the lines and grades given and in conformity with the plans, profiles and cross- seotione therefor. -1- I () • k All soft or unsuitable material shall be removed and the space re- filled with good earth or gravel. The Contractor, however, will not be required, in such oases, to excavate the mud, sand or other soft material to a greater depth than two (2) feet below sub- grade. All suitable material from cute shall be deposited in embankments, as specified by the Engineer. Where the amount of material excavated from the roadway is insuf- fioient to make the embankments to required crose - section, the extra material required shall be furnished by the Con- tractor from borrow -pits. If the borrow -pits are located within the street lines, their location, orose- seotion and grades shall be as approved by the Street Superintend- ent. No borrowing shall be allowed below gutter grades except by written specification of the Street Superin- tendent. Where the quantity of excavation exceeds that re- quired to make embankments to required crose - section, the surplus shall be used to widen the embankments uniformly, any part of it to be wasted only upon written specifica- tion of the City Engineer. No wasting of material above crown grade shall be allowed except by written specifica- tion of the City Engineer. Waste material shall be dis- tributed so as to present a neat appearance and not in- terfere with future improvements. The space over which fills are to be made shall first be cleared of all timber, brush and weeds; then thoroughly plowed and broken up to allow new and old material to unite and bond together. Embankments shall be formed of suitable material and shall be carried up full width in layers not to ex- -2- x; 1 teed one (1) foot each in thickness, and the teams made to travel as evenly as possible over the whole surface of each layer, both coming and going. The formation of well- defined ruts is specially prohibited. All clods or hard lumps of earth larger than six (6) inches in greatest dimension shall be broken up before being placed in em- bankment. Embankments shall be carried to such height above grade and to such increased width as may be necessary to provide for shrinkage and compression, and they must be maintained by the Contractor at their proper height, di- mension and slope until the work is finally accepted. All fills exceeding one (1) foot in depth and all places excavated below sub -grade and re- filled, and all pipe trenches or other deep excavations re- filled, shall be flooded with water and no portion of the maoadam shall be laid thereon until they will bear the weight of the roller. In embankments over or about masonry or other structures, the material shall be deposited in a manner so as not to unduly strain these structures. The Con- tractor shall make good, at his own expense, all damage caused by his failure to properly place material. At no time shall the roadway be plowed or broken up for a greater distance than one -half (1/2) mile ahead of the broken stone deposited on the sub - grade, it being the intent of these specifications not to interfere with the public travel any more than absolutely necessary. SECTION 3. SHAPING ROAD -BED: Before the Broken Stone is spread, where the nature of the soil per- mite, the entire width of the to -be- improved roadway shall -3- � s � be plowed to a depth of six (6) inches and thoroughly cultivated with a disc harrow, or some other suitable instrument* It shall then be alternately watered and cultivated until the water has penetrated all particles of earth to a depth of six (6) inches. It shall then be brought to a true oross - section, conforming to the estab- lished grades, allowance being made for compression, and in conformity with the required oross- section. The sub- _ grade shall then be thoroughly rolled. All depressions below the required grade shall be scarified, to allow good bond, and brought to grade with fresh material and again watered and rolled and the watering and rolling continued until the surface is uniform and no further compression is possible, Should the soil be light or sandy, or of such nature that it is impossible to consolidate as above de- scribed, the surface shall be drenched with water and the sub -grade rolled until the utmost compaction possible is obtained. Depressions made by the rolling shall be leveled up with good material and again rolled. Sho��ld sand be encountered which is in the opinion of the City Engineer of such a nature that it would be impossible to prepare a suitable sub -grade by the hereinbefore specified methods, the unsuitable material shall be excavated to a depth not to exceed 2 feet below sub -grade and re- f filled with good earth or gravel as hereinbefore specif- ied. Such portions of the roadway as cannot be reached by the roller shall be tamped solid. -4. r - No broken stone shall be placed until the sub- grade has been tested for grade, cross - section and con- dition and is acceptable to the City Engineer. SECTION 4. BROKEN STONE: The broken stone shall be of a uniform quality, clean, hard, durable rock, of a quality satisfactory to the City Engineer. It shall be screened to the following sizes: To pass through Not to pass through ring of ring of No. 1 stone 3 -1/2 " diameter 1 *" diameter. No. 2 stone 1 -1/2 " diameter 3/4" diameter. Not 3 stone 3/4" diameter 1/4" diameter. No. 4 stone 1/4" diameter and under and free from dust. No. 12 stone shall be No. 1 and 2, as above, com- bined in equal parts of each. 4 It may be crushed from quarry or ledge rock or from hard uniform boulders not less than five (5) inches in diameter, but in no case shall the crushed product contain more than five (5) per cent of smooth, rounded or water -worn surfaces. It shall contain no full round or half -round surfaces. SECTION 56 ASPHALT MACADAM PAVEMENT: Upon the sub -grade prepared as above specified, a layer of Broken Stone, known as No. 12 stone, shall be uniformly spread to such a depth that after being thoroughly watered and rolled, the surface shall be one fourth (1/4) inch be- low the surface of the finished pavement. All depress- ions shall be filled with stoke as described above and re- rolled. The sprinkling and rolling shall be continued -5- s dA until the stone ceased to sink under the roller, or creep in front of it and until the stone is firmly locked together and of such strength that a hervily loaded motor truck or wagon may be driven over the surface without cutting it up. The surface must be uniformly smooth and conform to the required cross - section and grade. Immediately before each application of asphaltum the contractor shall, if required, thoroughly sweep the surface of the macadam with rotary street brooms, of a type and in a manner satisfactory to the City Engineer. The purpose being to remove all loose part- icles of stone, screenings, dust, or foreign matter, After the stone, prepared as above specified, has dried to a depth of at least one (1) inch, asphalt- um , as hereinafter specified, shall be applied at the rate of eight tenths (.8) of a gallon per square yard of surface covered. Immediately after the application of said asphaltum a layer of "No. 3" stone as hereinbefore described shall be evenly spread upon the roadway and brought to a uni- form surface with a road grader in such thickness that after being thoroughly sprinkled and rolled, the surface shall be to the grade of the finished pavement. Then a second coating of asphaltum shall be appli- ed at the rate of four tenths (.9) of a gallon per square yard of surface and immediately covered with a light coat of rook screenings, hereinbefore described as "No, 4" stone, in such quantities as to combine with and absorb -b- all of the asphaltum and produce a uniform surface of pavement. It shall be watered and thoroughly rolled until it becomes hard and smooth, true to grade and cross- section and free from all hollows and irreg- ularities. If the temperature of the stone or the air is such that the asphaltum, stone, and screenings cannot be thoroughly combined and bonded together by the methods of watering and rolling hereinbefore specified, so as to produce satisfactory results, either or both of the asphaltum coats, after being covered with stone or screenings shall be thoroughly rolled with a hot roller of a type, and in a manner satisfactory to the City Engineer. The intent of the hot rolling being to thoroughly spread the asphaltum and bring it up through the material. All portions showing a tendency to be- come rich in asphaltum shall be re- covered and re- rolled and any dry or ravelled spots must be treated with asphaltum, covered and re- rolled. All broken stone and screenings shall be shoveled into place from a dumping platform or from the wagon, or spread by a self spreading wagon, or distributed by a bottom dump wagon, according to the speoifications of the City Engineer. Broken stone shall not be deposited upon the sub -grade for a greater distance than one - fourth (1/4) mile ahead of the first application of asphalt- um; it being the intent of these specifications to keep the work finished as close as possible and not unduly expose the loose rock to damage from travel, dust, ate. -q. III,, SECTION 6. ASPHALTUM: It shall be a natural asphaltum that has been refined or one made by distill- ation of petroleum having an asphalt base. It must be free from free carbon and suspended insoluble matter. Not less than ninety -nine per cent (99%) shall be soluble in carbon bisulphide. Not less than ninety -eight and five tenths per cent (98.5 %) shall be soluble in carbon - tetrachloride. Not less than eighty per cent (80 %) nor more than ninety -four (94 %) shall be soluble in 860 Beaume gasoline. Penetration according to the District of Columbia Standard, with a No. 2 needle using 100 grammes for five seconds at 770 Fahrenheit shall bebetween 1250 and 150 0 . It shall contain not more than twenty per cent (20%) nor less than seven per cent (70) fixed carbon. A briquette of one square centimeter cross- section, being elongated at the rate of one centimeter per minute, shall at 77° Fahrenheit show a ductility of at least one hundred centimeters. It shall not lose more than two per cent (2 %) when 20 grammes are heated for five (5) hours at a temperature of 3250 Fahrenheit in a tin box 2 1/2 inches in diameter, nor shall the penetration at 77° Fahrenheit, after such heating be less t)aan one half of the original penetra- tion. SECTION 7. APPLYING ASPHALTUM; The asphaltum shall be applied by a pressure spraying machine which will spread the asphaltum uniformly over the surface of the road in a manner satisfactory to the City Engineer, -s- � v 1 using the specified amount per square yard of sur- face. It shall be applied at a temperature of not less than three hundred fifty (350) degrees Fahrenheit, nor more than four hundred fifty (450) degrees Fahren- heit. - ,R'J.r -Fi '4a /- /X If necessary to re -heat the asphaltum to comply with above requirements, it shall be done al the ex- pense of the Contractor. In no case shall live steam or water be injected into or allowed to enter the as- phaltum after it has been received by the Contractor. In the process of applying, care must be taken not to soil the curbs or walks. No asphaltum shall be applied until the sur- face which is to receive it is satisfactory to the City Engineer. Before any tank of asphaltum is ap- plied it must be inspected by said City Engineer to determine its quantity and temperature. All truck tanks used for the distribution of asphaltum shall first be submitted to the City Engin- eer, who will gauge and mark the capacity in gallons of said tanks and determine whether they are suitable for the proper distribution of asphaltum. SECTION 8, PROTACTION OF IMPROM ENT. The Contractor shall exercise due precaution to prevent damage to the Improvement in its various stages dur- ing construction and until accepted. He shall, wher- ever necessary, construct fences or barriers to pre - - vent the public from injuring the improvement. Any dust, mud, earth or other foreign material of any nature, carried or deposited upon the course of stone, or upon an asphalt surface before the final applica- tion of material, shall be removed by the Contractor -9- at his own proper expense, and the surface thoroughly cleaned before further work progresses. SECTION 9. ROLLING: All rolling herein specified, except hot rolling, shall be done with a power roller of the three wheel macadam type, weighing not lose than twelve (12) tons, exclusive of fuel and water and having a compression of not less than four hundred (400) pounds per inch width of tire, All rolling shall begin at the sides of the road and gradually work towards the center, and under no circumstances shall the center be rolled first. In all cases the rolling shall be continued until there is no more compression possible. SECTION 10. TWATERING: The Contractor shall provide all water required, and apply a sufficient quantity in each case to thoroughly wet the material, under the supervision of the City Engineer. SECTION 11. CONCRETE,. (a) Cement: All cement shall be "Portland" cement and shall conform with the standard speoifioa- tions for cement adopted in August, 1909, by the Am- erican Society for Testing Materials, The cement shall be suitably protected from the weather and piled so as to permit of access for tally, inspection and identification of each ship- ment. It shall be delivered in the original pack- age with the brand and the name of the manufacturer plainly marked thereon. -10- All cement, the samples of which do not test up to the required standard, shall be immediately removed from the work and shall not be egain brought upon the work. (b) Other materials: The concrete shall be composed of broken stone or screened gravel, and sand, all of which shall be clean, hard, durable, well graded and satisfactory to the City Ingineer - "Portland" cement and fresh clean water. The sand shall be of such size that all of it will pass a screen having four (4) meshes per lineal inch, and at least forty (40), but nor more than eighty -five (85) per cent by weight will be retained on a sieve having thirty (30) meshes per lineal inch. Not more than seven (7) per cent by weight shall pass a sieve having one hundred (100) meshes per lineal inch. The broken stone or gravel stones shall vary in dimension from one - quarter (1/4) to two and one- half (2 -1 /2) (c) inches in greatest dimension. Composition: All concrete, unless otherwise specified, shall be composed as follows: One (1) cubit foot (94 pounds) of cement, two (2) cubic feet of sand, and four (4) cubic feet of broken stone or screened gravel, and water, which shall be added in such proportions as the City En- gineer may, from time to time, determine, said com- position to be known as Class A Concrete. Cement Mortar finishing coat shall, unless -11- otherwise specified, be composed of one (1) part of Portland Cement and two (2) parts of coarse sharp screened sand. The finishing coat shall be thoroughly mixed by turning at least three times dry, It shall then be wet, turned twice and immediately put in place as hereinafter specified. (d) Mixing and Placing: If the concrete is mixed mechanically, a mixer shall be used, in- to which the material, including the water, can be precisely and regularly proportioned, Hand -mixed concrete shall be mixed on a water tight level platform as follows: The cement and sand shall first be thoroughly mixed dry, in the proportions specified, in proper boxes. Clean water shall then be added and the materials thoroughly mixed and deposited on the broken stone or screened gravel, which has been previously drenched with water. The ingredients shall then be thoroughly mingled and turned over until each stone is covered with mortar. The batch shall than be carefully deposited without delay and thoroughly rammed in layers not more than six (6) inches in thickness until the water flushes to the surface and all the voids are filled, The concrete shall not be allowed to fall from any considerable height, Should voids be discovered when the forme are taken down, the defective work is to be removed and -12- 3 , the space re- filled with one to one cement mortar. r i_ On exposed surfaces all form marks and imperfect- ions shall be removed and the finished surface left smooth and uniform. Centers and forms, satisfactory to the City Engineer, shall be provided by the Contractor. They shall be made of planed lumber and shall fit the curves and shapes of the work. The sheathing shall be laid tight and shall be made clean before using. Forme shall be true to line and grade, satis- faotorily supported and firmly secured. They shall remain in place as long and shall be removed when and in such order as the City Engineer may specify, r and shall be replaced by new ones when they lose their proper dimensions or shape. In connecting new concrete with concrete already set, the surface shall be cleaned, rough- ened and mopped with a mortar composed of one (1) part cement and one (1) part sand. All newly built concrete shall be kept shaded from the sun and well sprinkled with water for at least ten (10) days. In laying concrete under water, the con- Crete shall not fall from any considerable height, but be deposited in the allotted place in a com- pact mass. The concrete must not be rammed, but leveled with a rake or other suitable tool im- mediately after being deposited. No concrete shall be laid in running water. No back - filling or loading whatever shall be -13- placed on or against the concrete masonry until specified by the City Engineer. Reinforcing rods shall be placed where shown on the drawings, substantially wired to in- tersecting rods before any concrete is run into the forms, and held firmly in position until em- bedded. Rods may be splioed by lapping their ends forty times the diameter of the rod. SECTION 12. STBEL: All steel used under these specifications shall be of the best quality, tough and ductile. All steel shall be made by the open hearth process. Re- rolled material will not be accepted, but all bare are to be rolled from new billets. The finished bare must be free from injurious seams, flaws, cracks or other defects, and have a smooth, uniform and workmanlike finish. Materials which, subsequent to the tests pre- scribed below and its acceptance, develop weak spots, brittleness, cracks or other imperfections, or are found to have injurious defects, will be replaced by the Contractor at his own cost. The steel shall conform to the requirements of the Standard Specifications for concrete rein- forcing bare of the American Society for Testing Materials adopted August, 1913, for the Structural Steel grade. Bending tests may be made by pressure or by blows. Bare shall be tested in their finished form, -14- All reinforcing bars shall be free from loose scales, excessive rust, oil, grease, paint or other coating of any character which would reduce or des- troy the bond. All reinforcing bare shall be deformed bare having their corrugations at right angles to their length, or other bare which are equally satisfactory. SECTION 13.

The exposed ends of all pipes shall be pro- teoted by means of a rod not less than one -half (1/2) inch in diameter folded in edge of sheet forming end section of pipe, or by means of galvanized angle iron 1 -1/2" x 1-1/2"x 1/4 ", to be attached to ends of pipe by means of rivets placed not more than eight (8) inches apart from center to center. The bottom of the excavation for the culvert shall be true to grade and thoroughly compacted, the pipe carefully placed in position with the intake end -16- K) I It headed up stream, and with seams on sides. If pipe sections are built of two sheets, the seams shall be placed quartering, fine gravel, sand or good earth shall then be filled around the pipe up to the center and thoroughly tamped with a thin tamping bar. The excavation shall then be filled in layers not to edceed six (6) inches in thickness, each layer being thoroughly tamped. All pipe shall be delivered at proper lo- cation fourteen (14) days prior to installation, in order to give sufficient time for chemical an- alysis of the metal. SECTION 14. CEMENT CURBS: Cement curbs shall be constructed in the locations and to the dimensions and sizes shown upon the plans, profiles and cross- sections on file in the office of the City Engineer. The top and bottom surfaces shall be level. The radius of curb returns shall be as shown on the plans. Excavation for ourbing shall be made to such width as to allow of ease of setting forms in proper positions. The foundation ground shall be tamped hard and solid and brought to true grade of the bottom of the curb, as shown on the plans and cross- - section. Unless otherwise provided for, all soft or spongy material shall be removed to a depth of three (3) inches below sub- grade, and the space -17- iii filled with good earth or gravel of a quality that will pack when moistened. This eab -grade shall be moistened and the whole foundation tamped or rolled until it is solid. The surface of the sub -grade shall be thoroughly moistened immediately prior to placing the concrete. If the soil upon which the cement curb is to be laid is adobe, it shall be brought to a surface two (2) inches below the sub - grade hereinbefore described, and the space filled with a layer of sand or gravel and thoroughly com- pacted by tamping or rolling. Forms for the curbs shall be of a width equal to the full depth of the curb and must be free from warp and imperfections, and held rigidly in place, true to lines and established grade. In order to insure a uniform thickness of the finishing coat upon the face of the curb to the required depth below the gutter line, the form against which the face of the body of the curb is tamped shall be con- structed as shown upon the plans. Expansion joints of a type and thickness satis- factory to the City Lugineer shall be placed at curb returns and at intervals along the curb of not more than twenty (20) feet. The intersections of the top and sides of the r curb faces shall be on a curve of not over one -half {1/z) inch radius. I In constructing the cement curb the Contractor shall provide entrance for Private driveways where -18- designated by the City Engineer, which shall not be more than ten (10) feet in length and of a depth below the top of the curb as shown on the plans. Upon the sub- grade, prepared as hereinbe- fore specified, shall be laid the concrete base which shall be thoroughly tamped until free mortar appears on the surface, and the surfaoe is free from all dust or foreign matter. Upon this con- crete base shall be placed a finishing coat one - half (1 /2) inch in thickness; the composition of the concrete body and the finishing coat shall be as herelnbefore described under the heading of "concrete ". The lapse of time between the laying of the concrete base and the application of the finishing coat shall be not more than two (2) hours. The top of the curb shall receive a coat one -half (1/2) inch thick. The back face from the top down to a distance of two (2) inches and the front face of the ourb from the top to one (1 ") inch below the gutter line shall receive a coat of one -half (1/2 ") inch in thiokness each. The finishing coat shall be well floated and trow- elled into the body of the concrete so as to form one compact mass, free from voids. It shall then be smoothly polished and marked off vertically into blocks of uniform length not less than two and one -half (2 -1/2) nor more than three and one- half (3 -1/2) feet in length, a marking being placed -19- at every point where an expansion joint, previously described, was introduced; the marking to be done with a tool which will leave the corners rounded and insure free movement of the concrete at the joint. The completed curb shall be protected from damage by accident, traffic or otherwise, and must be thoroughly watered and kept wet for ten (10) days after completion. After curing, back - filling must be made to the elevation of the top of the curb, and tamped firm, The finished curb must show a true, straight face and top of uniform width, free from humps, sags, or other irregularities. When a straight edge five (5) feet long is laid on the face or top of curb, ex- cept at grade changes or ourves, the surface shall, at no place, vary more than one - quarter (1/411) inch from the edge of the straight edge. Curb plank must be maintained on rear of curb till finishing coat is placed on the face of the curb, and no curb plank shall be stripped in less than one -half (1/2) hour after the concrete has been tamped into place. SECTION 15. CONCRHTE GUTTER: The found- ation for the full width of the gutter shall be brought to the proper sub -grade at the bottom sur- face of the finished gutter, as shown upon the plane. Unless otherwise provided for in the plans, all soft or spongy material shall be removed to a depth of three (3 ") inches below said sub -grade and replaced -20- iii' with gravel or good earth of a quality that will pack when moistened. This sub -grade shall be moistened and the whole foundation tamped or rolled until it is solid. The surface of the sub -grade shall be thoroughly moist- ened immediately prior to placing the concrete. If the soil upon which the concrete gutter is to be laid is adobe, it shall be brought to a surface two (2 ") inches below the sub -grade with sand or gravel - which shall be thoroughly compacted by tamping or roll- ing. The excavation and preparation for the gutter shall be done at the same time as that for the curb- ing. The concrete gutter shall be of such width and thickness as shown on the plans. Before the concrete for the gutter is laid, forms of two (211) inch plank shall be firmly placed 1, for the outside, or street edge of the gutter, ex- tending the full depth of the gutter, the top of the form being flush with the top of the finished our- face. Upon the sub- grade, prepared as hereinbefore specified, the concrete body of the gutter shall be placed to its full depth, in one filling, and tamped till water flushes to the surface and all voids are filled. Expansion points of a type and thickness sat- isfactory to the City Engineer shall be placed across the gutter at intervals of not more than twenty (20) feet. Except where curb already exists and is to be r -21- left in place, the joints shall be placed at the same points and intervals along the gutter as noted for the curbing. The gutter shall be trowelled smooth along the curb for a space of two (2 ") inches from the intersection of the curbing; also, a two (211) inch strip each side of the marking lines, said marking lines to be continuous with thos4 ou the curb, and running across the full face of the gutter. A two (211) inch strip along the outside edge of the gutter shall be trowelled smooth with a tool that will round the edge to a radius of not less than one -half (1/2 ") inch. The balance of the surface of the gutter shall be given a granolithic finish. The completed gutter shall be protected from damage by accident, traffic or otherwise and must be thoroughly watered and kept wet for fourteen (14) days after completion. SECTION 16.
