(3) Compaction: Rolling shall begin as soon as practicable after the spreading. The contractor shall submit to the engineer the rolling system he proposes to use for the compaction of the mixture. Rollers shall be in good conditions, capable of operation without backlash. Steel wheel rollers shall be equipped with scrapers. All rollers shall have a functioning water system for moistening each roller or wheel. Base course shall be compacted to 95% of laboratory density. Surface course shall be compacted to 98% of laboratory density.
(d) Asphaltic concrete: Work consists of asphaltic concrete surface course over aggregate base.

DIVISION 6. SEWER LINES
Subdivision III. Excavation
Sec. 19-77.14 General.
Contained herein are the requirements for excavation and work connected therewith as required for the satisfactory completion of the project. (Ord. 69, §2)
Sec. 19-77.15 Classification of excavated materials.
(a) Sewer trench excavation shall be classified as either "Trench Excavation (Class A)" or "rock excavation (Class C)" and shall be paid for as stated in basis of payment and as shown on the bid form. The MSHTD standard specifications Section 203 shall be used to define excavation type.
(b) Excavation pits as shown on plans are for estimating purposes only by engineer/owner. The contractor shall ascertain on site conditions and bid job accordingly. (Ord. 69, §2)
Sec. 19-77.16 Trench excavation.
(a) The work included under "Trench Excavation" shall comprise any necessary clearing of the line of which the sewer is to be constructed; of making all excavations of all materials of every description which may be encountered as "Trench Excavation" and/or "earth excavation" and "rock excavation"; of furnishing and placing of all shoring, sheeting and bracing which may be necessary to protect the work and to execute it; of shaping the bottom; of furnishing all equipment which may be necessary to keep the trenches free from water so that the sewers may be placed in the dry; of providing for the uninterrupted flow of surface water or sewage adjacent to the line of the work during the progress of the work so as not to interfere with the natural surface flows; of protecting all pipes, conduits, culverts, bridges and all other public and private property which may be endangered by the work; and of hauling away all surplus excavated material.
(b) Borings when shown on the Plans are for information only. There is not expressed or implied agreement or guarantee that the depths or character of materials are correctly shown or that conditions affecting the work will not differ from those shown on the Plans.
(c) All excavation shall be carried out accurately to the line and grade as shown on the Plans.
(d) If the bottom of the excavation is found to be unstable or to include ashes, cinders, refuse, vegetable or other organic materials considered unsuitable by the engineer, the contractor shall excavate and remove such unsuitable material to the depth required and backfill to the original subgrade with granular backfill, well-compacted by means of mechanical tampers or vibrators in 6 inch layers, except as noted hereinafter. If over-excavation is required by the engineer, the quantity of such authorized additional excavation shall be determined by the engineer, and the contractor shall be paid by the owner for the over-excavation at the unit price bid for "Ditching & Backfill" and for the "Crushed Rock for Subgrade Replacement". Any unauthorized over-excavation shall also be backfilled as described above but no payment shall be made for such over-excavation and backfilling.
(e) All excavation shall be dewatered before any construction is undertaken therein. Concrete shall be placed only upon dry firm foundation material and pipe shall be laid only in dry trenches.
(f) Trenches shall be opened in advance of pipe laying no more than is necessary for the prompt and proper performance of the work and shall in no case exceed 300 feet of open trench in advance of pipe laying on any line under construction. (Ord. 69, §2)
Sec. 19-77.17 Limitations on width of trench.
(a) Trenches shall be dug so that all pipes can be laid to the alignment and depth required. The width of trenches shall be ample to permit the pipe to be laid and jointed properly and the backfill to be placed and compacted. Additional width shall be provided where shoring or bracing is used.
(b) In order to avoid superimposed loading in excess of the designed and specified pipe strength and to provide sufficient room for proper installation and bedding of the pipe, the trench widths for the sewer pipe sizes used shall be kept within the limits specified as follows:
Size of Pipe Minimum Width Maximum Width
8" & Below 2' - 0" 2' - 0"
10" - 12" 2' - 0" 2' - 6"
15" 2' - 8" 3' - 2"
(c) The contractor may, at his option, where working conditions and rights-of-way permit, and with the approval of the engineer, excavate sewer trenches with sloping sides, but with the following limitations:
(d) Only braced vertical trenches will be permitted in streets, alleys or easements which are paved, or in locations where the trenches are in close proximity to utilities, building, railroad tracks, or other installations which could be endangered by the excavation.
(e) Where trenches are excavated with sloping sides for pipe sewers to be installed, the slope shall not extend below a point one foot above the extrados of the pipe, and the trench excavation below that point shall be carried out with vertical sides for widths not exceeding the maximum widths provided for in these specifications above.
(f) Any trench excavated with sloping side for pipe sewers which has a width at one foot above the top of the pipe in excess of the maximum trench width permitted will result in an increased load on the sewer pipe. If slopes are allowed to extend below this level, or if the width of the trench at this level is greater than the specified maximum width, additional strengthening of the pipe is required, and accordingly, where such conditions exist, the contractor shall consult with the engineer prior to backfill to determine additional procedures required but as a minimum shall place granular fill between the bottom of the trench and the level of one foot above the intrados of the pipe from the outside of the pipe to the undisturbed sides of the trench. No payment shall be made for such extra procedures in backfilling which shall become necessary on account of the contractor's operations in excavating trenches of excessive widths below the specified levels.
(g) Through all tillable property, a minimum of one foot of topsoil shall be removed from the trench and stockpiled for use in backfilling the upper one foot of trench after the lower portion of the backfill has been completed.
(h) The elevation shown on the profiles of the sewers are those of the flowline of the pipes. In excavating the bottom of the trench in material other than material which may cause damage to pipe such as rock or rock-like material, the contractor shall place 4 inches of "Granular Bedding" under the barrel of the pipe and shall shape the trench bottom by hand to fit the lower section of the pipe, as shown on the Plans, recessing for the bell holes where the bell projects beyond the barrel of the pipe in such manner as to relieve the bell of all load. After the pipe has been aligned, granular bedding shall be evenly deposited on both sides of the barrel up to a distance of 6 inches over the top of the pipe. If unauthorized over digging occurs the contractor shall, at his expense, replace the excess excavation with granular bedding material. If excavation of subgrade is in rock a minimum of 4" of granular bedding is required beneath the bottom of the sewer pipe.
(i) Where necessary to protect the labor, the work, or adjacent property, the contractor shall provide and install shoring. The sides of the trench shall remain held by bracing or sheeting of either wood or steel. Shoring shall remain in place until the backfill has proceeded to a point where it can be safely removed. If, in the opinion of the engineer, damage is likely to result from withdrawing shoring, it shall remain in place. Payment for all lumber left in place as order by the engineer will be paid for at the price bid per MFBM (one thousand board feet of board material) for "Lumber Ordered Left in Trench", which payment shall cover the whole cost of furnishing all material, labor, equipment, tools and all other incidentals which may be necessary for placing and leaving the lumber in the trench. This payment shall not cover the cost of furnishing, placing and removing lumber used for bracing during construction, which need not remain in place upon completion of the backfill. Payment for lumber used as temporary bracing shall be included in the price for "Ditching & Backfill".
(g) Payment for "Ditching & Backfill", including backfill and surplus disposal, shall be made at the price bid for "Ditching & Backfill". Payment shall cover the whole cost of furnishing all equipment, labor, tools, materials and all other incidentals which may be necessary for carrying out the necessary excavation, pumping and fluming and taking care of dry and storm water flows, protecting adjacent improvements, backfilling, including tamping of the backfill as herein specified, stockpiling topsoil and backfilling with topsoil where required, maintaining temporary macadam or gravel surface in satisfactory safe condition for use by traffic until the permanent pavement restoration is carried out, disposing of the surplus excavated materials, removing any existing sewers, and cleaning up of the site, including the furnishing, placing and removing of all sheeting and bracing which may be necessary during construction, but which is not ordered left in place and which is removed as the earth backfill is being carried out.
(k) Payment shall be from centerline to centerline of manholes and for the various depths indicated as measured from the surface to the pipe flow line. (Ord. 69, §2)
Sec. 19-77.18 Rock.
(a) The responsibility of the contractor with respect to the use of explosives in blasting includes compliance with all laws, rules and regulations of the State, the City and the insurer; governing the keeping, storage, use manufacturer, sale, handling, transportation or other distribution of explosives. All operations involving the handling, storage and use of explosives shall be conducted with every precaution by trained, reliable men under satisfactory supervision. Blasts shall no be fired until all persons in the vicinity have had ample notice and have reached positions out of danger therefrom. The contractor shall remove all earth, to allow for rock measurement, prior to blasting; and protect debree from scattering to maximum extent possible.
(b) After a blast is fired, the contractor shall thoroughly scale the excavation, removing all loose and shattered rock or other loose material which may be dangerous to the workmen, and the excavation shall be made safe before proceeding with the work. The fact that the removal of loose or shattered material may enlarge the excavation beyond the required limits shall not relieve the contractor from the necessity for making such removal, and the contractor shall not be entitled to compensation therefore. Pay width for trench rock shall be trench "Minimum Width". Also provide underground type insurance for blasting.
(c) Where rock or other hard material occurs in the trench so that any portion of the pipe would rest on rock or hard material, the trench excavation shall be carried to a depth below the planned grade so that no rock or other objectionable hard material is closer than 4" inches to the outside of the pipe at any point. The width of trenches shall be ample to permit the pipe to be laid, jointed, and covered properly. (Ord. 69, §2)
Sec. 19-77.19 Excavation for appurtenances.
(a) All structures shall be founded on undisturbed subsoil. Unauthorized excavation below the specified structure subgrade shall be replaced by and at the expense of the contractor, with concrete.
(b) The contractor shall make all necessary excavations for appurtenances. Excavation shall be made in open cut to the alignment and depth as shown on the profiles and drawings except as otherwise indicated in the specifications and drawings.
(c) In excavation for manholes, and cleanouts and similar structures, it shall be sufficient to leave at least 12 inches in the clear between their outer surfaces and the embankment or timber which may be used to hold and protect the excavation. In all cases the clearance between the outer face of structures and the surrounding excavation shall be sufficient to allow the proper performance of the work including the plastering of exterior wall surfaces where required by the specifications or plans.
(d) Wherever necessary to prevent caving the excavation shall be adequately sheeted, braced and drained so that workmen may work therein safely and efficiently. Where the bottom is in rock, the excavation limits shall allow solid rock to be exposed and cleaned of all loose material and cut to a firm surface before any foundation concrete is placed.
(e) Whenever wet or otherwise unstable soil that is incapable of properly supporting the structures, as determined by the engineer, is encountered, such soil shall be removed to the depth required and the excavation backfilled to the proper grade with coarse sand, fine gravel, or other suitable material as may be authorized. All excavations for structures shall be kept dry and no pipe or reinforcing steel shall be installed in water and no water shall be permitted to inundate the reinforcing steel before concrete has been placed. All excavations shall be kept dewatered to the extent that water will not come in contact with any concrete within 12 hours after placing. When excavations are carried below ground water elevations such excavations shall be dewatered by lowering and maintaining the ground water level at least 12 inches below such excavations during all construction, including subgrade excavation, placing of reinforcing steel or pipe, placing of concrete, plastering or masonry, and shall be maintained in a dry condition until all concrete has been placed and allowed to harden for at least 12 hours as specified above. (Ord. 69, §2)
Sec. 19-77.20 Construction along or across highways, railroads and creeks - work adjacent to or crossing highways.
(a) Work adjacent to highways. Work within the right-of-way limits of state highways shall be performed in accordance with the Highway Department's requirements, such as; necessary precautions to protect traffic by use of signs, signals, flagmen, and watchmen; accomplishing work in a manner that will not interfere with traffic, highway entrances, maintenance of the highway, or drainage facilities; and materials and methods of placing and compacting backfill. The above and other requirements of the Highway Department which differ or are in addition to those specified herein shall be performed in accordance with the Highway Department's requirements when working within the right-of-way limits of state highways. The contractor shall also obtain necessary permits to work on the right-of-way.
(b) Highway crossings. The crossings under highways shall be constructed in full accordance with the State Highway Department's requirements. The requirements of the Highway Department will govern the method and procedures of construction and materials used for the crossing. The contractor shall obtain the requirements of the Highway Department prior to construction. The contractor shall be reasonable for all damage to the highways due to his operations.
(c) Railroad crossings. Pipe crossing under, on, or thru the railroad right-of-way shall be constructed in full accordance with the railroad company's requirements. The entire construction, including material, construction procedures, methods, etc., shall be approved by the railroad company. Contractor shall obtain permits and requirements from the railroad prior to construction.
(d) Sewer bridges. Sewer bridges shall be constructed where indicated on the Plans and where the sewer crosses the creek above the creek bed. Bridges shall consist of cast or ductile iron pipe strapped to concrete piers. Pipe ends to be mechanical joint with a solid sleeve or transition coupling to be used to join pipe on upstream and where pipe goes into ground and couples to normal pipe used on the job. The bridges shall be constructed as shown on the drawings. (Ord. 69, §2)
Sec. 19-77.21 Backfilling trenches.
(a) Backfill methods and materials shall comply with the requirements for the specific type of pipe being used. Two different broad categories of pipe are possible: one being a rigid pipe and the other being defined as a flexible conduit type of pipe. Pipe falling into the classification of rigid are cast and ductile iron, clay and concrete. Flexible conduit type of pipe are plastics such as PVC pipe, which are subject to deflection control.
(b) The backfilling of the completed pipe sewers shall commence immediately upon the completion of the sewer laying with care being taken that the operation of backfilling does not disturb the pipe joints.
(c) All backfill to a level of 6 inches over the top of the pipe shall conform to class 1, Granular Angular, material and as further defined in "GRANULAR MATERIAL FOR BACKFILL' these specifications.
(d) The pipe trench shall be brought to grade by filling the approximate 4" from the subgrade to the bottom of the pipe (4" in rock) by using "Granular Bedding" compacted to a firm dense bedding. The compaction of bedding may be obtained by raking and "walking" or "Trafficking" bedding material to firm dense condition. Placing pipe on an uncompacted, loose granular bedding is unacceptable. Over excavation of subgrade which exceeds 6 inches will require bedding to be placed in maximum 6" lifts compacted by power ramming equipment. Subgrade which becomes saturated with ground or surface water, because contractor has failed to accomplish dewatering as required, and otherwise becomes unsuitable or unstable shall be removed as required by the engineer/inspector and replaced in maximum 6" lifts compacted by power ramming or vibratory equipment. No additional payment for crushed rock for subgrade replacement shall be paid for over excavation where dewatering has not been accomplished.
(e) After the pipe has been installed the "Granular Bedding" shall be added in maximum 6" lifts to levels of the horizontal centerline of the pipe. This material shall be compacted by "shovel slicing" the granular material the full length of each side of the pipe in lifts not exceeding 6 inches. "Shovel slicing" shall be extensive whereby the granular material is so worked in under the horizontal centerline of the pipe for the full length of each side to whereby compaction obtained provides meaningful resistance to further shovel slicing or further settlement under workman's feet. In placing this initial backfill of "granular bedding material" to the centerline of the pipe unacceptable will be the procedure where the granular bedding material is dumped on the pipe to depths greater than the centerline of the pipe and spread therefrom. After completion of shovel slicing compaction to the horizontal centerline of the pipe the granular backfill shall be "walked in" the entire length, both sides such that the granular backfill is unyielding under the workman's feet.
(f) For flexible conduit types of plastic pipe such as PVC, ABS, or Truss pipe the remaining backfill to a point 6 inches above the top of the pipe shall be made with the same "Granular Bedding" and compacted in maximum 6" lifts to minimum 6" above top of pipe as per initial backfill to centerline of pipe.
(g) For rigid types of pipe such as iron, concrete or clay; the remaining backfill to a point 6 inches above the top of the pipe shall be lightly compacted "Granular Bedding" to the trench walls.
(h) At the completion of backfill to the level of 6 inches over the pipe the granular material shall be level from trench wall to trench wall. Granular Bedding will not be as a separate bid item and the contractor shall include necessary cost elsewhere.
(i) Above this level excavated material from the trench will be acceptable as backfill except herein following and as noted for special locations herein below. Care shall be taken to eliminate large clods, stones and clay masses and also organic matter within 2 feet from the top of the pipe.
(g) Backfilling shall be completed to insure restoration of the ground surface to its original condition.
(k) Backfill in open fields may be completed without further compaction above 6 inches over the extrados. The fill shall be mounded over the trench to allow for future settlement. The top one foot of backfill shall be made through tillable areas with stockpiled topsoil.
(l) Backfill of trenches in paved streets will be uncompacted excavated material from trenches. Any surplus excavated material which can not be placed in trenches shall be hauled from worksite. The final 6 inches in paved streets shall be 6" of crushed base rock per Restoration of Secondary Roads.
(m) It is called to contractors attention that the General Requirements, Section 01500, Item 9, "Responsibility of Contractor for Backfill Settlement" requires contractor to be responsible for maintenance of trench excavation during the 1 year guarantee period. While these specifications require no compaction of backfill above granular material in streets it may be of contractors best interest to minimally compact and roll trenches with wheeled vehicles, (loader, grader, etc.) in the upper most depths to minimize maintenance, speed natural settling and minimize additional crushed base rock surfacing.
(n) Where the contractor excavates below the planned subgrade for pipe lines, the over-excavation shall be backfilled with granular material well compacted in 6 inch layers. Only granular material placed in over-excavation authorized by the engineer will be measured and paid for at the price bid per cubic yard for "Crushed Rock for Subgrade Replacement", which payment shall cover the whole cost of furnishing all materials, labor, equipment, tools and other incidentals necessary to furnish and place the granular material. The volume to be paid for under this item shall be limited to the volume computed within the payline widths and for the depths and lengths as ordered by the engineer. Crushed rock placed in over-excavation not authorized by the engineer shall receive no additional compensation. Crushed rock required for stabilization of trench bottom caused by not keeping ground or surface water out of trench will not be given additional compensation. (Ord. 69, §2)
Sec. 19-77.22 Manholes and lampholes.
Wherever excavating is necessary beyond the external line of manholes and lampholes, these spaces shall be refilled with a suitable material. Backfill around these will correspond to the type of backfill that exists on the adjacent pipelines. (Ord. 69, §2)
Sec. 19-77.23 Pavement and sidewalk replacement.
(a) All pavement, curbing, gutter, drives, patios or sidewalks removed during construction of the project for any reason shall be replaced unless otherwise shown on the drawings or directed by the engineer, the replacement construction shall conform in type, quality, and dimension to that of the portion so removed. Replacement shall proceed as soon as possible after the sewer line work in that area is completed.
(b) Payment will be made for items within construction limits as defined elsewhere. Items outside construction limits that are damaged will be replaced at contractor's expense. (Ord. 69, §2)
Sec. 19-77.24 Surface restoration.
(a) General. The contractor shall not allow the site of the work to become littered with trash and waste material but shall maintain same in a neat and orderly condition during the progress of the work.
The contractor shall clean up all dirt from paved surfaces, not allowing same to pack on the roadway or create a traffic nuisance.
(b) Cleaning up. After completion of construction and prior to final acceptance, the contractor, at his expense, shall remove from the sites all construction equipment, all unused or waste material, all debris, and all removed material and equipment unless specifically stated otherwise. Any existing structures above or below ground, any existing trees, shrubs, and grass in residential or pastoral areas; and any other item which during construction was removed or damaged shall be repaired to its original condition, at the contractor’s expense. If repair to original condition is not possible, the contractor shall replace any damaged or removed item at his expense. It is the intent of this specification that the site after construction shall be restored to its original condition as nearly as possible.
(c) Seeding. Unless otherwise indicated on the drawings, all areas that had existing grass prior to construction shall be fertilized, seeded, and mulched after completion of construction work. Seeding shall be done only when soil and climatic conditions are such as to insure reasonable success. Seeding shall not be done during periods when, in the opinion of the engineer, the soil is too wet to permit satisfactory results.
(d) Seeding mixture. The seeding mixture shall be proportioned by weight, and shall consist of the following varieties and quantities per acre (minimum percentages of purity and germination are listed behind each type of seed).
40 lbs. Kentucky Blue Grass.......................... (80%-P; 70%-G)
10 lbs. Recleaned Red Top............................ (90%-P; 85%-G)
20lbs. Perennial Rye Grass............................ (98%-P; 90%-G)
10 lbs. White Dutch Clover............................ (95%-P; 85%-G)
Seed shall be of the previous year's crop, and must be entirely free from seed of Bindweed, Canada Thistle and Johnson Grass.
(e) Fertilizer. Fertilizer shall have an analysis of 10, 6, 4, or an approved equivalent in the pellet form. Fertilizer shall be broadcast uniformly on the area at such a rate that each acre to be seeded shall receive a total of 160 pounds of the actual three nutrients (nitrogen, phosphoric acid, and water soluble potash) contained in the fertilizer. (ie combined weight of N, P & K).
(f) Mulch. Mulch seeded areas at rate of 100 lbs per 1,000 sq. feet spread evenly in open areas such as yards and pasture. Mulch wooded areas, at minimum of 50 lbs per 1,000 sq. ft. Immediately following mulching anchor by forcing mulch into soil with disc-pacher or other suitable means.
(g) Reseeding. If satisfactory results are not obtained, in the opinion of the engineer, the contractor will be required to reseed and refertilize those areas on which satisfactory grass cover has not been obtained. (Ord. 69, §2)
Sec. 19-77.25 Borings.
(a) Borings shall meet all requirements of MO. Highway and Transportation Department and contractor shall obtain necessary permits and do all work in accordance with their requirements, if boring is on their road.
(b) Boring shall be made so that line and grade of water line may be carried continuously thru encasement. Boring encasement to be steel pipe with a wall thickness of a minimum as per table. Encasement to be new, unused steel pipe with yield strength of 35,000 psi conforming to ASTM A53-B. Casing diameter to be as shown in table unless specifically bid differently in bid proposal. Contractor may use larger casing size if he desires, but shall be responsible for any job variations encountered by this choice.
(c) Contractor shall complete bore before other work is started so that slight misalignments can be compensated for in other work.
(d) While quality of work is required, this job is set up with the boring done first as previously stipulated to take advantage of a relaxed specification for casing alignment and grade that is possible within the confinements of the overall project layout.
(e) Casing shall be installed as boring equipment removes material from hole.
(f) Random lengths of steel casing may be used; but all ends must be V grooved-butt welded to adjacent casing pipe around the complete perimeter of the pipe. Welds to be water tight and shall be equal to or stronger than adjacent pipe. Casing joining procedures must be such that concentricity of the entire completed casing will be maintained.
(g) Boring to include all work of digging bore pit, casing and all items associated therewith, for the completed job.
(h) In some layouts part of the casing may be installed by open cut methods and attached to the ends of the bored casing. This will be shown as a separate bid item where and if included on the job.
(i) Some borings under local roads, etc. may be completed without casing. If this procedure is used a 40 piece of PVC pipe shall be used to insure that no joints exist in the bored area. (Ord. 69, §2)
Sec. 19-77.26 PVC installed in casings.
(a) When PVC is installed in casings the following procedures shall be followed:
(1) The entire casing shall be installed before any pipe is inserted into the casing. Inspection will be by lamping and a full circle shall be required to be seen to provide that the casing is concentric from end to end.
(2) Except as specifically shown otherwise on the plans, the minimum depth to the top of the casing shall in general be 3' - 0" below the lowest level of surface being crossed.
(3) A repair style coupling, dresser style coupling or similar device shall be installed on either side of the end of the casing in addition to the regular pipe joints to allow for future removal-repair of the PVC carrier pipe, where the pipe is a force main.
(4) PVC carrier pipe shall be as long as possible (40 feet) to minimize the number of joints contained within the casing. If it is possible to install PVC without a joint in the casing (because of shortness of casing length), it will be unnecessary to place PVC pipe on skids and the pipe may be laid directly on the casing.
(5) Whenever a PVC carrier pipe joint is required within the casing the PVC shall be placed on non biodegradable skids.
(6) To insure that pipe bell does not rest on casing use skids to support barrel of pipe. Skids to have at least 4 runners with a shoe height of a minimum of 1 inch. Shoe height of skid may be higher as required by bell diameter of carrier pipe. Shoe height of skid to be of such height that pipe cannot cork screw in casing.
Length of skid to be 4 inch minimum and be manufactured from non biodegradable material such as a plastic.
(7) Skid support shall be spaced as shown (in table 9 below) to insure adequate support of pipe.
(8) PVC pipe may be installed by winch drawn cable or jacking. The force used to install the pipe must spread over the pipe end on which it bears, by use of a flat piece of wood or other similar force sustaining material.
(9) Table of casing sizes and maximum skid support.
