EXCAVATION AND BACKFILL The work includes all excavation, backfill, grading, compaction, and associated work necessary for the construction of the improvements as shown on the plans or required to complete the work as contained in the contract documents. 4

5 Excavation, fill and backfill work includes transportation, backfill, selection, placing and compaction of the various classes of fill described under other applicable sections of these Specifications and the disposal of unsuitable or surplus materials at approved locations provided by the contractor. EXCAVATION AND CLEARANCES The excavations shall be made to conform with the lines of the finished structures wherever practical. The excavations shall not be carried below the required subgrades. The trench in which pipe, manholes or inlets are to be constructed shall be excavated from the surface and to such depths, and widths (not less than 12 inches nor more than 24 inches greater than the maximum external dimension of the structure) as will give suitable room for bracing and supporting, pumping and draining, and for removing from the excavation any material which the Township of Howell may deem inadequate for foundation. Any surplus material shall be distributed on the site or removed as directed by the Township of Howell. All excavations shall be of sufficient width to permit work to be done competently and safely. The length of the trench to be opened or the area of the surface to be disturbed and restored at any time will be limited by the Township of Howell with regard both to expeditious construction and convenience to the Township of Howell. New trenches will not be excavated if previous trenches are in need of backfilling or labor is needed to restore the surface of the ground to a safe and proper condition. All excavations for pipelines shall be clear of boulders, rocks, masonry or other similar material which shall be excavated to a level at least six inches below the bottom of the pipe, and shall be fully refilled with approved material mechanically compacted to provide a stable subbase. Rock or boulders shall be removed from sides of trenches to 12 inches minimum outside the wall or the pipe, unless permission to do otherwise is expressly given. Gravel or stone bedding shall be provided, placed and compacted to the minimum depths when indicated on the plans. The bottom of the trench shall be excavated where the earth is suitable for good foundation to the form and size of the lower portion of the pipe or other structure, so that there shall be full and adequate support for the structure which is to be built on it. Ample excavation shall be made under and around the pipe joints for joining and to relieve the bell of shearing forces. UNAUTHORIZED EXCAVATION Special care will be taken with the final six inches of all excavations. In no case shall the excavation be carried below the required subgrade by machine and backfill used to establish the required grade. Where the excavation has been carried below subgrade, the contractor shall, at his own expense refill such areas with compacted ¾ inch graded gravel or crushed stone to insure the stability of the structure or pipe. If the contractor excavates below the required subgrade for structures, the over excavation shall be filled with material subject to the requirements of the Township of Howell and may include 4500 psi concrete if so ordered by the Township of Howell. SHEETING AND BRACING The contractor shall fully comply with the applicable requirements of Federal OSHA. Where necessary for safety or to prevent disturbance, damage or settlement of adjacent structures, pipelines, utilities, improvements or paving, excavations shall be sheeted and braced. Any damage to new or existing structures occurring through settlement, water or earth pressure, or other causes due to inadequate 5

6 construction procedures of the contractor in any manner, shall be repaired by the contractor at his own expense. DEWATERING AND PROTECTION FROM FLOODING The contractor shall dewater the excavations promptly and continuously throughout the progress of the work and shall keep the excavations dry at all times until the structures to be built therein, are completed. Where work is to be performed below groundwater level, the contractor shall provide, operate and maintain dewatering facilities sufficient to maintain the excavation free from groundwater for the time required to complete the work in the proper workmanlike manner. The contractor shall protect uncompleted work from flooding during storms or from other causes. All pipelines or structures not stable against uplift during construction or prior to completion shall be thoroughly braced or otherwise protected. All necessary precautions shall be taken to prevent disturbance of, and to properly drain, the areas upon which concrete is poured, and upon which pipe is to be laid. All concrete shall be kept dry for one month after pouring. BACKFILLING EXCAVATIONS The contractor shall backfill excavations around structures, underneath paved areas, sidewalks, and other areas sensitive to settlements with bank run sand and gravel which shall be compacted to 90 percent of its modified proctor density determined in accordance with ASTM Specifications D T. All lumber, braces, construction articles, and rubbish shall be carefully removed from behind walls of structures. Unless otherwise specified, all trenches or excavations shall be backfilled and compacted to the original ground surface or to such grades as shall be required. The backfilling outside building walls shall be done in accordance with good practice to prevent after settlement around all structures and pipelines, and with appropriate equipment to protect same from damage. The Township of Howell reserves the right to make such selection of the material for various portions of the backfill as may be required for the satisfactory execution of the work. Backfill shall not be placed on ground that is frozen, nor shall backfill material be permitted to freeze during placing and compaction. Only such backfill material as is described herein approved by the Township of Howell shall be used. All boulders, rocks, trees, stumps or other unsuitable material shall be disposed of at approved locations off the site at no additional cost to the Township of Howell. As soon as practical after the pipe or masonry has been placed and the concrete has acquired satisfactory strength, as determined by the Township of Howell, the backfilling shall begin and shall be expeditiously completed. The contractor shall utilize approved mechanical vibratory compaction equipment to thoroughly consolidate backfill. The backfill shall be installed in approved lifts and compacted to achieve maximum consolidation and minimize subsequent settlement. All backfill in embankments shall be thoroughly compacted by rollers of approved size, type and weight for the particular fill materials. ADDITIONAL EXCAVATION AND FILL 6

7 Wherever undisturbed material found at the grades shown on the plans for the structural floors, footings or pipe inverts is not satisfactory in the opinion of the Township of Howell, the contractor shall make any additional excavations directed by the Township of Howell, and shall refill excavations to the required grade with compacted suitable fill material. The fill material shall be as specified under other applicable sections of these specifications. Fill material shall be spread in uniform horizontal layers that when compacted shall not exceed 8 inches in thickness. Each lift shall be compacted to 95%- of the modified proctor density in accordance with ASTM D T. The moisture content of the fill material shall be changed when necessary to attain the specified density. Changing of the moisture content of the fill material shall be accomplished by aerating the soil or by adding water to the fill as required. If wetting or drying is required, each lift shall be thoroughly mixed to ensure a uniform distribution of moisture. Compaction shall be accomplished by equipment designed for compacting the type of fill being used as approved by the Township of Howell. The contractor shall establish operating procedures to obtain uniform coverage of the area being compacted. During construction, the surface of the fill shall be graded to permit runoff of surface water at all times. BACKFILLING TRENCHES No trench or other excavation shall be backfilled until the structure or pipeline in it has been examined and approved. Immediately after inspection and approval the trench or other excavation shall be carefully backfilled with the suitable select excavated material and/or other material as detailed or ordered. Whenever the Township of Howell deems the excavated material unsuitable for backfilling the contractor shall furnish acceptable material as may be ordered by the Township of Howell. No large rock or frozen earth shall be put in the trench. Suitable material shall be used to fill evenly on both sides of the pipe and carefully tamped or rammed so as not to disturb the pipe joints, at the same time making the filled trench thoroughly compact until the filling reaches one foot above the top of the pipe. When the backfilling has been carried to one foot above the top of the pipe, it shall be thoroughly rammed with tools having faces of 25 to 36 square inches and weighing not less than 20 lbs. Rock in pieces weighing more than 50 lbs. shall not be put in the trench. All spaces between suitable pieces of rock shall be thoroughly filled by backfilling in alternate layers of rock and earth. All sheeting shall be withdrawn, unless otherwise ordered to remain in place in writing by the Township of Howell. As the trench is refilled, the sheeting and timbering shall be removed in such manner as to avoid the caving of the trench. The void left by the sheeting shall be carefully refilled by ramming or as otherwise directed.
