Proper and satisfactory means and devices for the exclusion and removal of all water entering excavated or low-lying areas, whether the water be surface runoff or groundwater, shall be provided at all times during construction. Water shall be removed as fast as it may collect in a manner that will not interfere with the execution of the work nor cause damage to property or the work in progress. Prior to excavation and fill placement, the groundwater table shall be lowered a minimum of 1 foot below the excavation bottom or as required to maintain stable conditions while this work is performed. The effectiveness of the water removal shall be satisfactory to the Engineer.

The Contractor shall be fully responsible for protection of work in progress due to damage caused by stream flow, flood flow, natural groundwater, seepage, surface runoff, or any combination of the same. Should damage occur, it will be repaired to the satisfaction of the Engineer at no additional cost to the Owner.

2.03.6 Random Fill: The Contractor shall furnish the labor, material, and equipment necessary to excavate, stockpile, load, haul, spread, and compact random fill and backfill materials necessary to prepare and construct the project complete. Fill materials shall consist of suitable soil and rock generated from excavations onsite. The Contractor is responsible for the placement of fill or backfill to the lines, grades, thicknesses, and dimensions as shown on the Design Drawings, or as required by the Engineer.

2.03.7 Preparation for Fill:

2.03.7.1 General Fill Requirements: Prior to placement of fill, all topsoil shall be removed as required by the Design Drawings and these Specifications. Topsoil shall be stockpiled and used to re-vegetate disturbed areas when the work is complete. Soils excavated from the construction areas may be used as fill provided they are free of organics, comply with these Specifications, and are moisture conditioned to achieve proper compaction.

Fill shall start on a level sub-grade. Sliver fills will not be allowed. The sub-grade and fill area shall be dewatered as required by Section 2.07 of these Specifications and shall be firm and approved by the Engineer prior to fill placement. The fill shall be placed and compacted in level lifts in accordance with these Specifications for the applicable fill type. Each fill lift shall be benched and keyed into adjacent slopes as the fill progresses.

The fill sub-grade surface shall be roughened to provide a suitable bond to the new fill without layering or lensing. The sub-grade of fill areas shall be approved by the Engineer prior to placement of fill. All existing soft wet sub-grade soil will be removed from the fill area as directed by the Engineer prior to placement of new fill. The vertical and horizontal extent of the excavation necessary to remove all unsuitable sub-grade materials will be as directed by the Engineer. Any undercut required to stabilize the sub-grade prior to fill placement will be as directed and approved by the Engineer. No over excavation to remove soft/wet soils will be allowed unless approved by the Engineer.

Use of rubber-tired equipment is not allowed in sub-grade areas which are to receive fill and the use of rubber-tired equipment in the fill areas should be minimized to the extent practical due to the potential for unstable pumping conditions to develop. Due to the clay, silt, and sandy soils present onsite, only low ground pressure tracked equipment will be allowed for use in fill placement.

The prepared ground surface upon which any fill is to be placed shall be free of all organic materials, shall be uniform and level as possible, and shall be compacted to the satisfaction of the Engineer. No fill shall be placed on frozen or soft/wet ground. Care shall be taken by the Contractor to minimize construction traffic over fill areas to minimize the potential for unstable "pumping" conditions to develop in the sub-grade and active fill surface prior to fill placement and compaction. Should the sub-grade or fill become unstable, the Contractor shall remove these materials and re-compact the same to provide a suitable fill surface prior to placement of additional fill as directed by the Engineer at no additional cost to the Owner.

2.03.8 Fill Materials: Fill materials required for the work consists of Random Fill. The fill materials shall comply with these Specifications or as approved by the Engineer.

2.03.8.1 Random Fill: Random fill and backfill shall be placed and compacted as required for the project as shown on the Design Drawings or as required by the Engineer.

Random fill shall consist of soil or rock materials obtained from the excavations onsite.

Material available from onsite excavations should be suitable for use as random fill if approved by the Engineer. Maximum particle size for random fill is 2 inches. Random fill materials shall be approved by the Engineer prior to use as fill.

2.03.8.2 Testing of Borrow Materials: All needed fill should be attainable on site.

Soils obtained on site may need to be modified to meet gradation and moisture requirements as directed by the Engineer. The Contractor shall sample and perform classification and laboratory compaction testing on representative samples of all fill materials obtained from the excavations. The sampling shall be performed under the direction of the Engineer. The testing lab shall also be approved by the Engineer and test results must be submitted to the Engineer for approval a minimum of 15 days before the material is hauled to the site or placed as fill. The fill must comply with these Specifications. Minimum testing shall include one (1) each of the following tests for each 250 CY of material excavated or hauled to the site, or when there is a noticeable change in material while work is progressing; Atterberg limits, Natural Moisture Content, Sieve Analysis with 200 wash, and Standard Proctor Compaction (ASTM D-698).

2.03.9 Fill Placement: The Contractor shall make a reasonable effort to remove roots, limbs, and rocks from the fill material in so much as is practical. No fill shall be placed in standing water, upon frozen earth, and no frozen material shall be placed in any portion of the fill. Material too wet to compact shall be dried prior to compaction and moisture shall be added to materials too dry to compact as required by these Specifications.

Sufficient discing equipment and a water truck shall be continuously available at the site and shall be used to manipulate the material to obtain the proper moisture content for compaction. Suitable sheepsfoot and smooth drum vibratory rollers shall be available onsite along with suitable hand compaction or walk behind compactors for tight areas.

All compactors shall be approved by the Engineer

Clods or lumps of material shall be broken down by tractor or other equipment necessary to accomplish this result. Each lift shall extend the full width of the area being filled before starting the next lift. Each layer shall be uniform in thickness and shall be spread and compacted as specified before the next layer is started. Fill which is comprised primarily of rock or rocky soil mixtures shall not be used to bed or backfill new piping.

At the close of each work day, or when work is to be stopped for a period of time, the entire surface of the compacted fill shall be sealed by a method approved by the Engineer. If, after a prolonged rainfall, the top surface of the embankment is too wet and plastic to work properly, the top material shall be removed to expose firm, dry soil. The top material so removed shall be disposed of at the Contractor's expense. The entire surface of any section of fill under construction shall be maintained in such condition that construction equipment can travel on any part of the section. Ruts in the surface of any layer shall be suitably filled or eliminated by grading before compaction. Care shall be taken to prevent excess travel over any section of the fill to avoid over-compacting that section. Use of rubber-tired vehicles on the fill area is prohibited unless approved by the Engineer. Areas of the fill which are over-compacted or lensed in any way due to traffic or other construction activities shall be scarified to a depth as required by the Engineer prior to placement of additional fill.

2.03.10Compaction: Complete control of the compaction operation shall be exercised under the direction of the Engineer. Care shall be taken to prevent over-rolling, weaving of equipment, and slickensides in the fill or backfill material. If any portion of the fill is over-compacted, that portion shall be worked with harrow, scarifier or other suitable equipment to a sufficient depth, and the material shall be re-compacted to achieve the desired density. Prior to and during the compaction operation, the material in each layer of fill shall have the best practical moisture content required for compaction purposes;

however, the moisture content shall not be less than 2% below or greater than 4% higher than the optimum moisture content as determined by the moisture/density relationship specified herein. The moisture content shall be uniform throughout the layer. No compaction will be permitted when moisture conditions are such that the required density cannot be obtained. Compaction requirements are as follows:

2.03.10.1 Random Fill: Random fill which contains less than 35% rock materials and/or is comprised primarily of a soil matrix or soft rock which will break down upon compaction, will be placed and compacted in maximum 8-inch loose lifts and compacted to a minimum of 95% of the maximum dry density as determined by ASTM D698. As stated, the moisture content at the time of compaction shall not exceed plus 4% or minus 2% of the optimum moisture content. Where hand compaction methods are required, the maximum loose lift thickness shall be 4 inches and compaction requirements will remain the same. Rocky soil mixtures which contain more than 35% of particles which are larger than the No. 4 sieve shall be placed in maximum 12-inch loose lifts and compacted with a minimum of 6 passes of a 20-ton vibratory smooth drum roller, or as approved by the Engineer to obtain a stable, dense, well compacted fill.

2.03.10.2 Testing: Field density and moisture content tests shall be performed by the

Contractor in accordance with these Specifications and the QA/QC plan as approved and directed by Engineer or his representative. Testing shall be performed in accordance with the maximum dry density and optimum moisture criteria developed for the fill material by the standard Proctor test (ASTM D 698) as specified herein. The Contractor shall furnish a suitable compactor(s) to facilitate fill placement and compaction. Compaction equipment must be approved by the Engineer. One compaction test will be performed by the Contractor for each 50 CY of compacted fill. A minimum of one test shall be performed per working shift if less than 50 CY of fill is placed during a working shift.

Test results shall be reported to the Engineer in writing daily.
