Procedure. Optimum moisture content shall mean the moisture content at
maximum dry density as determined above
2.0 SITE PREPARATION
2.1 Clearinq - Areas to be graded shall be cleared and grubbed of all vegetation and
debris. These materials shall be removed from the site by the Contractor.
2.2 Stripping - Surface soils containing roots and organic matter shall be stripped
from areas to be graded and stockpiled or discarded as directed by the Owner.
In general, the depth of stripping of the topsoil will be approximately six inches.
Deeper stripping, where required to remove weak soils or accumulations or
organic matter, shall be performed when determined by the Geotechnical
Engineer. Strippings shall be removed from the site or stockpiled at a location
designated by the Owner.
2.3 Removal of Existing Fill - Existing fill soils, trash, and debris in the areas to be
graded shall be removed prior to the placing of any compacted fill. Portions of
any existing fills that are suitable for use in compacted fill may be stockpiled for
future use. All organic material. topsoil, expansive soils. oversize material or
other unsuitable material shall be removed from the site by the Contractor or
disposed of at a location on site, if so designated by the Owner.
2.4 Ground Surface - The ground surface exposed by stripping shall be scarified to
a depth of six inches, moisture conditioned to the proper moisture content for
compaction. and compacted as required for compacted fill Recompaction shall
be approved by the Geotechnical Engineer prior to placing fill.
3.0 EXCAVATION
3.1 General - Excavations shall be performed to the lines and grades indicated on
the plans. The data presented in the geotechnical investigation report is for
information and only the Contractor shall make his own interpretation with regard
to the methods and equipment necessary to perform the excavation and to obtain
material suitable for fill.
3.2 Materials - Soils which are removed and are unsuitable for fill should be placed
in non-structural areas of the project. When necessary, these soils may be
placed in deeper fills if approved by the Geotechnical Engineer.

3.3 Treatment of Exposed Surface - The ground surface exposed by excavation
shall be scarified to a depth of six inches, moisture conditioned to the proper
moisture content for compaction, and compacted as required for compacted fill.
Recompaction shall be approved by the Geotechnical Engineer prior to placing
fill.
4.0 STRUCTURAL FILL
4.1 Limits — Structural fill, if required for fill beneath foundations or concrete sla-on-
grade should be medium dense to dense gravel with sand.
4.2 Material —We recommend the gradation for structural fill be 100% passing the 3-
inch sieve. 25 to 65% passing the No 4 sieve, and no more than 20% minus No.
200 sized material The structural fill should have a liquid limit less than 25 and a
plasticity index less than 15.
4.3 Placement - All fill materials shall be placed in layers of eight inches or less in
loose thickness and uniformly moisture conditioned. The lift should then be
compacted with approved compaction equipment to achieve at least 98% relative
compaction in areas under structure foundations. No fill material shall be placed,
spread. or rolled while it is frozen or thawing, or during unfavorable weather
conditions.
4.4 Benching - Fill placed on slopes steeper than 5 horizontal to 1 vertical shall be
keyed into firm, native soils or rock by a series of benches. Benching can be
conducted simultaneously with placement of fill. However, the method and
extent of benching shall be checked by the Geotechnical Engineer.
4.5 Compaction Equipment - The Contractor shall provide and use sufficient
equipment of a type and weight suitable for the conditions encountered in the
field. The equipment shall be capable of obtaining the required compaction in all
areas, including those that are inaccessible to ordinary rolling equipment.
4.6 Recompaction - When, in the judgment of the Geotechnical Engineer, sufficient
compaction effort has not been used, or where the field density tests indicate that
the required compaction or moisture content has not been obtained, or if
"pumping" or other indications of instability are noted, the fill shall be reworked
and recompacted as needed to obtain a stable fill at the required density and
moisture content prior to placing additional fill materials.
4.6 Responsibility - The Contractor shall be responsible for the maintenance and
protection of all embankments and fills made during the contract period and shall
07-115-03 Page 3 of 5 July 1, 2010

bear the expense of replacing any portion which has become displaced due to
carelessness, negligent work, or failure to take proper precautions.
5.0 UTILITY TRENCH BEDDING AND BACKFILL
5.1 Material - Pipe bedding shall be defined as all material within six inches of the
perimeter of the pipe. Backfill shall be classified as all material within the
remainder of the trench. Material for use as bedding shall consist of clean,
granular materials. and shall conform to requirements for bedding material listed
in the Standard Specifications.
5.2 Placement and Compaction - Pipe bedding shall be placed in thin layers not
exceeding eight inches in loose thickness, and conditioned to the proper
moisture content for compaction.
All other trench backfill shall be placed in thin layers not exceeding eight inches
in loose thickness, conditioned to the proper moisture content, and compacted as
required for adjacent fill. If not specified, backfill should be compacted to at
least 97% relative compaction in areas under structures, utilities,
roadways, parking areas, concrete flatwork, and to 90% relative
compaction in undeveloped areas.
6.0 AGGREGATE BASE FOR CONCRETE SLABS
6.1 Material - Aggregate base for concrete slabs shall consist of crushed base rock
conforming to requirements of the Standard Specifications.
6.2 Placement - Aggregate base shall be compacted and kept moist until placement
of concrete. Compaction shall be by suitable vibrating compactors. Aggregate
base shall be placed in layers not exceeding eight inches in thickness. Each
layer shall be compacted by at least four passes of the vibratory compaction
equipment or until 95% relative compaction has been obtained.
7.0 SUBGRADE AND AGGREGATE BASE FOR PAVED AREAS
7.1 Subgrade and Subbase Preparation - After completion of the utility trench
backfill and prior to placement of aggregate base. the upper six inches of
subgrade soil shall be uniformly compacted to at least 95% relative compaction
This may require scarifying, moisture conditioning. and compacting in both cut
and fill areas.
