Only under special conditions and with the approval of the Village Engineer, shall trenches be left open overnight. Trenches which are allowed to be left open overnight shall be completely enclosed with suitable fencing or lighted barricades. When the trench contains water or when required by the Village Engineer, the exposed end of the pipe shall be securely closed with a watertight plug.
(FF) Cleanup scheduling.
(1) General cleanup, including completion of rough grading of backfilled trench areas, shall continuously progress along with, and shall lag no further than 100 feet behind, the pipe installation operations.
(2) Fine grading and restoration work not dependent on weather or subject to seasonal limitations shall also progress concurrently with and shall lag no further than 500 feet behind pipe installation operations.
(GG) Excavation. The trench shall be excavated so that the pipe can be laid to the alignment and grade shown on the plan, taking into consideration the bedding specified. Excavation shall include removal of all materials encountered and disposal (off the site) of those materials not suitable or needed for backfilling of the trench. Excavation shall not proceed ahead of pipe laying a distance that will result in a cave in. All adjacent structures encountered, above and below the ground surface, shall be properly supported.
(HH) Width of trench.
(1) If the maximum trench widths noted on the plans are exceeded, unless otherwise authorized by the Village Engineer, the contractor shall construct a concrete cradle or other type of approved bedding to provide support for the additional load.
(2) When sand bedding is used, the maximum trench widths shall be used to permit compaction of the bedding around the pipe.
(3) If stone bedding is used, a minimum six inch clearance shall be provided on each side of the pipe with the maximum trench width as tabulated.
(II) Pipe bedding.
(1) Pipe bedding is defined as the material placed from a minimum of four inches below the pipe to the centerline of the pipe. It shall consist of stone or sand, as noted on the bedding detail. The bedding shall be removed under the bell so that the pipe barrel will be uniformly supported for its full length.
(2) The bedding material shall be placed and compacted uniformly on both sides of the pipe to prevent lateral movement. Mechanical methods of tamping shall be used when it is possible to do so without damaging the pipe. Bedding shall be placed in layers of six inches or less as necessary to obtain thorough compaction around the pipe.
(3) In the event density tests become necessary to resolve a question of the sufficiency of compaction of bedding material, the minimum acceptable density shall be considered to be 95% of maximum density as determined by the AASHTO T99 method.
(4) Stone used for bedding shall not lose more than 7% by washing. Stone used for this purpose shall pass a 3/4 inch sieve and be retained on a 1/4 inch sieve.
(JJ) Concrete cradle. Where called for on the plans, a concrete cradle shall be constructed using MDOT Grade 30P concrete. The cradle shall extend half-way up the sides of the pipe.
(KK) Laying of pipe.
(1) Proper and suitable tools and appliances for the safe and careful handling, conveying, and laying of the pipe shall be used. Care shall be taken to prevent the coating of castings or ductile iron pipe from being damaged. Pipe, valves, hydrants, and fittings strung along the route shall be placed in such a manner that they will not be submerged or collect water. Dropping of material directly from a truck or platform is prohibited. All pipe and castings shall be carefully examined for defects. If any materials are found to be defective, they shall immediately be removed from the site.
(2) All lumps, blisters, and excess coal-tar coating shall be removed from both the bell and spigot ends of each length of pipe and each fitting. The outside of each spigot and the inside of each bell shall be wire brushed and wiped clean, dry, and free from oil or grease immediately prior to installation. The inside of the pipe shall be free of dirt and debris. Any damage to exterior pipe coating shall be repaired with an approved coating before the pipe is laid.
(3) Each pipe shall be inspected by the contractor for possible defects and compliance with the plans before being placed in the trench. Joint surfaces shall be free of foreign matter. Pipe laying operations shall follow immediately behind the excavation.
(4) Pipe shall be laid from the lower end of the sewer upstream, with bell ends up grade. The use of brick, lumps of clay, wood, and the like, to level the pipe will not be permitted. Pipe shall be thrust home and if joints do not remain tightly closed or construction is in saturated sand, a cable and winch, or other approved means, shall be used to maintain a tight joint. Under no circumstances shall pipe be dropped directly into the trench.
(5) All pipe shall be laid to line and grade as called for on the plans. Each pipe as laid shall be checked by the contractor. The trench shall be excavated to provide equal clearance on both sides of the pipe. After the pipe is set, care shall be taken in backfilling so as not to disturb its line or grade. As work progresses, the interior of the pipe shall be thoroughly cleaned. At all times the open ends of the pipe shall be covered to prevent foreign matter from entering.
(LL) Backfilling.
(1) Backfilling is defined as the placement in the trench of approved material by an acceptable method, from the top of the bedding to proposed ground surface grade. All backfill material shall be free from cinders, ashes, refuse, organic matter, boulders, rocks or stones, or other material which, in the opinion of the Village Engineer, is unsuitable. Unless otherwise authorized by the Village Engineer, all excavations shall be backfilled at least to a point one foot above the pipe immediately after installation.
(2) From the center of the pipe to a point one foot above the top of the pipe, the trench shall be backfilled with sand approved by the Village Engineer, placed in six inch layers, and thoroughly compacted.
(3) Backfilling to grade shall not fall more than 100 feet behind pipe laying unless otherwise permitted by the Village Engineer. In locations where compaction of the backfill to a specific density is not required by these standards, backfill may, where practicable, be machined placed. Excavated material (other than clay) may be used for backfill and compacted by a small dozer in lifts of not over nine inches loose measure. Machine compaction of backfill may be required by the Village Engineer.
(4) No frozen material shall be buried more than two feet below the final elevation of ground. At no time shall frozen materials be permitted for use as backfill under pavement structures.
(5) All backfill placed within three feet of manholes, catch basins, gate wells and other underground structures shall be approved sand, placed in one foot layers and compacted. After the structure and/or exterior masonry plaster has set up sufficiently to resist, damage, backfilling shall be performed in a manner that will not cause unequal pressure on the structure.
(MM) Construction in unstable soils or fill sections.
(1) Pipe and pipe appurtenances must be supported on a firm foundation. The trench bottom shall remain stable during backfilling and all subsequent pipe laying operations. When unstable trench bottoms (wet clays, sands, and the like) are encountered, it will be necessary to excavate below design depth to stable, non-compressible ground and backfill to grade with approved select materials: slag, crushed stone, gravel, and the like, 1/4 inch to 3/4 inch in size.
(2) Where organic materials (peat, marl, muck, and the like) exist at the trench bottom, it shall be necessary to remove these to stable soils and backfill to grade with the aforementioned select materials. Where the material below plan grade is unstable to such a degree that it cannot be removed and replaced with an approved material, the contractor shall construct supports as recommended by the Project Engineer and approved by the Village Engineer.
(3) Where it is necessary to lay pipe in a fill area, unstable or unsuitable material shall be removed before fill material is placed. The embankment shall be of suitable material, one vertical on two horizontal fill slopes, and shall be placed in layers not exceeding one foot in thickness compacted to 100% of maximum density as determined by the AASHTO T99 Method, to the proposed top of the pipe. The embankment shall not be less than four diameters plus 12 feet wide at the invert of the pipe and shall be continued up to provide no less than three feet of cover over the pipe.
(NN) Pipe clearance in rocks. Rocks, boulders, and stones over two inches in diameter shall be removed to provide a clearance of at least six inches from any part of the pipe or appurtenances.
(OO) Roadway and waterway crossings. All work within a road right-of-way or a waterway shall be performed in accordance with the requirements of the governmental body having jurisdiction over the right-of-way involved. Notice and permits as required shall be given and secured from said governmental body before work starts.
(PP) Trench box. If the trench box rides below the top of the pipe, then care must be taken to protect the integrity of the pipe bedding, particularly when movement of the trench box leaves a void in the pipe bedding. Care must also be taken to ensure that movement of the trench box does not pull the pipe joints apart and, if necessary, the pipe lines should be secured with a wood cross-block, cable, and winch at the downstream manhole.
(QQ) Bored and jacked casings.
(1) Requirement. The boring and jacking of steel casings shall be installed in any areas considered to be detrimentally affected by open cut construction in the opinion of the village.

(3) Installation.
(a) Casing pipe. Casing pipe shall be installed in a continuous augering (or mining) and jacking operation with the casing pipe installation following directly behind the face of the excavation. Water shall not be introduced during the boring-jacking operation.
(b) Grouting. The annular space between the outside surface of pipe and the inside surface of casing pipe shall be pressure grouted with approved materials. The diameter of the casing pipe shall be of sufficient size to ensure proper placement of the pipe to plan line and grade and to allow the proper installation of pressure grouted material. The ends of the casing pipe shall be closed with a masonry bulkhead at least eight inches thick.
(c) Minimum boring distances. All work shall be performed from boring and jacking pits adequately sheeted to prevent damage to the roadway, railway, and the like. The minimum distance from the edge of the pavement to the trench or boring and jacking pit for dual highway and interstate routes shall be 30 feet. For curb or guardrail section, railway track, or two-lane highway, the minimum distance will vary from shoulder point to the toe of slope, as shown on the plans or as directed by the Village Engineer.
(RR) Rip-rap.
(1) Rip-rap shall be installed at all locations as indicated on the plans.
(2) Typically, all rip-rap shall be installed on a suitable geotextile fabric.
(3) Rip-rap material shall be natural stone, limestone, or broken concrete free of any reinforcement.
