Dig trenches to the uniform width required for particular item to be installed, sufficiently wide to provide ample working room. Provide six inches to nine inches clearance on both sides of pipe or conduit. B. Where rock is encountered, carry excavation six inches below required elevation and backfill with a six inch layer of crushed stone or gravel prior to installation of pipe. C. For pipes or conduit five inches or less in nominal size and for flat bottom multiple‐duct conduit units, do not excavate beyond indicated depths. Hand excavate bottom cut to accurate elevations and support pipe or conduit on undisturbed soil. D. For pipes or conduit six inches or larger in nominal size, and other mechanical/electrical work indicated to receive subbase, excavate to subbase depth indicated, or, if not otherwise indicated, to six inches below bottom of work to be supported. E. Except as otherwise indicated, excavate for exterior water bearing piping (water, drainage) so top of piping is not less than 3'‐0" below finished grade. F.

Make at least 2 tests at locations directed by the Landscape Architect. F. When, during progress of work, field tests indicate that installed compacted materials do not meet specified requirements, provide additional compaction until specified density is achieved, or remove and replace defective materials with new materials as directed by the Architect. Cost of additional labor, materials, and testing to attain specified density at Contractor's expense. G. Percentages of Maximum Density Requirements: 1. Compact soil to not less than the following percentage of maximum density determined in accordance with ASTM D‐1557: The required new fill to attain the finish grades, including the backfill in any overexcavations, should be placed in maximum 8 in. thick lifts and compacted to not less than 98% and 95% of the maximum modified dry density, ASTM D 1557‐91 below and above the footing founding levels, respectively. Clean granular soils, such as well graded sand or sand and gravel, conforming at least to NJ State Standard Specification soil classification, should be used for compacted fill. Lawn or Unpaved Areas: Compact top 6" of subgrade and each layer of backfill or fill material to at least 90% of its maximum dry density as determined by ASTM D1557 test procedures. Pavements and Site Improvements: Compact top six (6) inches of subgrade and each layer of backfill or fill material to at least 95 percent of its maximum density. H. Moisture Control: 1. Where subgrade or layer of soil material must be moisture‐conditioned before compaction, uniformly apply water to surface of subgrade, or layer of soil material, to prevent free water appearing on surface during or subsequent to compaction operations. 2. Remove and replace, or scarify and air dry, soil material that is too wet to permit compaction to specified density. 3. Soil material that has been removed because it is too wet to permit compaction may be stockpiled or spread and allowed to dry. Assist drying by discing, harrowing, or pulverizing until moisture content is reduced to a satisfactory value. 3.07 BACKFILL AND FILLING: EARTHWORK 02210‐6 RAMAPO COLLEGE OF NEW JERSEY MANSION ENTRY AND STAIRS ALTERATIONS RCNJ PROJECT NO. 2014‐24‐01C A. Excavations shall be backfilled as soon as practical after installation of the work with suitable material obtained from the excavation. All suitable excavated material shall be stockpiled as necessary and used for backfill before any other backfill material is to be supplied. Backfilling around structures shall begin after the concrete has been cured and acquired 60 percent of the specified strength and the structure has been adequately braced or supported. Backfill shall be placed and compacted such that the differential elevation on either side of the structure does not exceed three feet to avoid creating unbalanced lateral pressures. B. Stockpiled excavated material shall have adequate erosion control measures and shall not be located within the dripline of existing trees nor where the possibility of siltation of any surface water exists. When stockpiled material interferes with natural drainage, necessary procedures shall be employed to permit surface and subsurface flow. C. Subgrade in areas to receive fill, shall be conditioned and compacted to a density equal to or greater than the existing dry density of the in‐place soils below that level. D. General: Place acceptable soil material in layers to required subgrade elevations, for each area classification listed below: 1. Under foundations, satisfactory on‐site soils, imported granular borrow fill, or drainage fill shall be used, as directed by the Architect. 2. In excavations, use satisfactory excavated or imported granular borrow material. 3. Under planting areas, use satisfactory excavated or imported granular borrow material. 4. Under walks and pavements, use subbase material, or satisfactory excavated or imported granular borrow material, or combination of both. 5. Under slabs, use approved excavated on‐site soil, imported granular borrow fill, or drainage fill material. 6. Under piping and conduit, use subbase material where subbase is indicated under piping or conduit; shape to fit bottom 90 deg. of cylinder. 7. If the foundation soils at or below subgrade shall be considered unsuitable as an adequate foundation material for the work, select material as specified shall be used to replace the unsuitable material. 8. The unsuitable subgrade soils shall be removed to such widths and depths as the Landscape Architect may direct. E. Backfill excavation as promptly as work permits, but not until completion of the following: 1. Acceptance of construction below finish grade including, where applicable, EARTHWORK 02210‐7 RAMAPO COLLEGE OF NEW JERSEY MANSION ENTRY AND STAIRS ALTERATIONS RCNJ PROJECT NO. 2014‐24‐01C dampproofing, waterproofing. 2. Inspection, testing, approval and recording locations of underground utilities. 3. Removal of concrete formwork. 4. Removal of shoring and bracing, and backfilling of voids with satisfactory materials. Cut off temporary sheet piling driven below bottom of structures and remove in manner to prevent settlement of the structure or utilities, or leave in place if required. 5. Removal of trash and debris. 6. Permanent or temporary horizontal bracing is in place on horizontally supported walls. F. Placement and Compaction: 1. Contractor shall be responsible for the means, methods, techniques, sequences, and procedures of construction to compact the backfill to the required densities and to prevent surface settlement and damage to utilities. The means, methods, techniques, sequences and procedures of construction to compact the backfill shall suit the condition and type of soil used as backfill. The thickness of layers of backfill shall meet the requirements of the compaction method chosen. 2. Place backfill and fill materials in layers not more than eight (8") inches in loose depth for material compacted by heavy compaction equipment, and not more than six inches in loose depth for material compacted by hand‐operated tampers. 3. Before compaction, moisten or aerate each layer as necessary to provide optimum moisture content. Compact each layer to required percentage of maximum dry density for each area classification. Do not place backfill or fill material on surfaces that are muddy, frozen, or contain frost or ice. 4. No compacting shall be done when the material is too wet to be compacted properly; at such times the work shall be suspended until the previously placed and new materials have dried out sufficiently to permit proper compacting, or until such other precautions are taken as may be necessary to obtain proper compaction. 5. Place backfill and fill materials evenly adjacent to structures, piping or conduit to required elevations.
