3. As a result of the Contractor submitting to the Contracting Officer a written request showing evidence of errors in the original design data used to determine design quantities that cause a pay item total to change by 15 percent or more. The evidence must be verifiable and consist of calculations, drawings, or other data that show how the designed quantity is believed to be in error.

B. Staked Quantities (SQ) - These quantities are determined from staked measurements prior to construction.

C. Borrow – common or select material obtained from an off-site source.

PART III – EXECUTION

3.01 Excavation – Unless noted otherwise, excavation is Unclassified, remove existing material to subgrade elevations and horizontal extent indicated, regardless of character of materials and obstructions encountered.

A. Clearing and grubbing - clear and grub plant material prior to excavation. Clear and remove plant materials within the limits of excavation, including fill areas. Selectively prune brush and trees to allow access for equipment and structures when plants and trees are designated to remain. Perform additional clearing and grubbing where indicated to create areas free of plant material in storage areas or inside fenced areas.

1. Grubbing - excavate the main mass of root and plant material below ground in areas to be excavated or where otherwise indicated on the drawings. Remove any roots which protrude into trench or structural excavations. When grubbing creates cavities below finished grade, perform backfill and grading according to following parts of this Section to restore the grubbed area to compacted, finished grade.

2. Disposal – unless NOTED ON DRAWINGS, disposal of material from clearing and grubbing shall be by the following methods and at Contractor’s option.

a. Remove and dispose – dispose legally at a State-approved landfill

b. Chip and spread – chip and shred vegatative material into pieces no larger than 1 inch diameter and 6 inches long. Spread chips in a layer 2 inches or less on project areas SHOWN ON DRAWINGS or as directed by the COR.

B. Unauthorized excavatioin - unauthorized excavation, as well as resulting remedial work directed by COR, shall be at Contractor's expense.

1. Remedial work - Under footings or foundation bases, fill unauthorized excavation by extending indicated bottom elevation of footing or base to excavation bottom, without altering required top elevation. Lean concrete fill or concrete slurry may be used to bring elevations to proper position, when acceptable to COR.

Elsewhere, backfill and compact unauthorized excavations as specified for authorized excavations of same classification, unless otherwise directed by the COR.

C. Unsuitable material - if unsuitable materials are encountered at required subgrade elevations, carry excavations deeper and replace excavated material as directed by COR. Removal of unsuitable material and its replacement as directed will be paid on basis of contract conditions relative to changes in work.

3.02 Material Storage - Stockpile excavated materials where directed, until required for backfill or fill. Place, grade and shape stockpiles for proper drainage. Locate and retain soil materials away from edge of excavations. Do not store within drip line of trees indicated to remain. Dispose of excess soil material and waste materials as herein specified.

3.03 Site Fill – Form fills and embankments from suitable common or select material obtained from on-site excavation or, when necessary, from borrow. Place in uniform lifts to required subgrade elevation. Compact each lift as specified elsewhere in this Section.

A. Ground surface preparation - remove vegetation, debris, unsatisfactory soil materials, obstructions, and any other deleterious materials from ground surface prior to placement of fills. Plow, strip, or break-up sloped surfaces steeper than 1 vertical to 4 horizontal so that fill material will bond with existing surface.

When existing ground surface has a density less than that specified under 3.07 Compaction, break up ground surface, pulverize, moisture-condition to optimum moisture content, and compact to required depth and density.

B. Placement - place fill materials in uniform layers. Hold layers to thickness that will achieve specified compaction. Placement shall start in the deepest area and progress approximately parallel to the finished grade.

Before compaction, moisten and mix each layer as necessary to provide optimum moisture content. Do not place or fill material on surfaces that are muddy, frozen, or contain frost or ice. Do not use frozen fill material.

3.04 Compaction - Compact site fill and backfill in a controlled fashion. Place materials in uniform horizontal lifts adjacent to structures, piping or conduit to required elevations. Take care to prevent wedging action of backfill against structures or displacement of piping or conduit by carrying material uniformly around structure piping or conduit to approximately the same elevation in each lift.

A. Placement - control soil compaction during construction by placing material in level, loose, even and successive lifts.

1. Depth of lifts - the resulting compacted depth of each lift shall not exceed six (6) inches.

B. Compactive effort – site fill and backfill compaction shall be obtained by a minimum of three (3) passes over the entire surface of each lift by motorized mechanical means with equipment designed for compacting, such as a muli-wheel rubber tired roller, steel wheel roller, sheepsfoot roller, vibratory plate, or rammer.

Remove and replace, or scarify and air dry, soil material that is too wet to permit compaction. Material 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.

Do not compact material when the moisture varies more than 4% above or 1% below the optimum moisture content. A uniform moisture content will be required throughout the layers of fill material. Wetting or drying manipulation shall be required if necessary to accomplish this. Suspend compaction operations when satisfactory results cannot be obtained because of rain or other unsatisfactory conditions.

3.05 Grading - Finish earthwork surfaces to line and elevation. Uniformly grade areas within limits of grading as shown on plans, including adjacent transition areas. Smooth finished surface within specified tolerances, compact with uniform levels or slopes between points where elevations are indicated, or between such points and existing grades.

3.06 Maintenance - Protect earthwork areas from wet-weather traffic and erosion. Keep free of trash and debris. Repair and re-establish grades in disturbed, settled, eroded, and rutted areas to specified soil density and final grading tolerances.

A. Settling - where settling is measurable or observable in earthwork areas during general project warranty period, remove surface (pavement, lawn or other finish), add backfill material, compact, and replace surface treatment. Restore appearance, quality, and condition of surface or finish to match adjacent work, and eliminate evidence of restoration to greatest extent possible.

3.07 Disposal of Excess and Unsuitable Earthwork Material - Transport all excess suitable excavated material to a designated waste area. Stockpile material, spread material as indicated on the drawings, or shape material at the waste area as directed by the COR.

A. Unsuitable material - remove unsuitable excavated materials, rubble and debris and dispose legally off-site.
