A. Unclassified Excavation: Shall consist of the material excavated and
its placement, regardless of its nature.

B. Rock Excavation: Removal of material shall be considered rock
excavation when it consists of igneous, metamorphic, and sedimentary
rock which cannot be excavated without blasting or the use of a tractor
having a power rating in excess of 195 net hp, with a rear-mounted,
heavy-duty, single-tooth ripping attachment.

C. Common Excavation: Removal of materials which can be excavated using
a rear-mounted, heavy-duty, single-tooth, ripping attachment mounted on
a crawler tractor with a power rating of 195 net hp or less shall be
considered common excavation.

D. Muck Excavation: Shall consist of the removal and disposal of
deposits of saturated or unsaturated mixtures of soils and organic
matter not suitable for foundation material regardless of moisture
content.

D. Fill Material: Shall be mineral soil, free from peat, frozen
material, brush, trees, roots over 2 inches (50 mm) in diameter and
rocks over 6 inches (150 mm) in greatest diameter obtained from the site
during excavation.

E. Topsoil: Surface soil, approximately 6 inches (150 mm) in depth that
supports growth of vegetation and contains organic matter. Topsoil shall
be free from subsoil, debris, and stones larger than 1 inch (25 mm) in
diameter.

1.3 QUALITY ASSURANCE

A. Failure Criteria: Not limited to the following:

1\. Settlement of backfill below natural ground surface.

2\. Evidence of leakage of the piping.

3\. Malfunctioning of buried electrical or piping systems.

1.4 PROJECT AND SITE CONDITIONS

A. Borrow Sources: Shall be as approved by the Contracting Officer prior
to excavation.

B. Environmental Conditions:

1\. Excavate areas that have become saturated with oil, gasoline, or
bituminous products to a depth of 12 inches (300 mm) beyond contaminated
materials; backfill with approved material.

2\. \[Finish slopes according to the drawings.\] \[The final surface
shall be similar to a surface obtained by using a farm disk or harrow
parallel to the contours and shall blend with the adjacent terrain.\]
\[Hand rake as necessary to remove excess material in areas inaccessible
to construction equipment.\] \[Grade to produce a well‑drained
surface.\] \[Excess material from trench excavation shall be placed over
the backfill in an inverted \"U\" shape.\]

[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS

A. General: Material excavated shall be considered unclassified.

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

B. Fill Material: Shall be approved before use. Material from
excavations shall be used, unless it contains ice or frozen earth,
debris, high moisture content, or is specified in other sections to be
replaced. Materials removed in clearing and grubbing shall not be used
for backfill. Backfill shall not contain rock larger than
\[[   ]{.underline}\] inches (\[[ ]{.underline}\] mm) in diameter.

B. Crushed Rock Backfill:

1\. Plasticity Index shall be as determined by AASHTO T 90, not to
exceed 9 for portion passing No. 40 sieve.

C. Bedding: Shall be \[round\] \[or\] \[angular\] \[stone\] \[sand\]
\[or\] \[gravel,\] \[or other angular\] \[fine‑grained and free‑draining
soil. 1/2‑inch (13 mm) minus crushed or pit‑run aggregate.\] \[as shown
on the drawings.\] \[materials from the excavation that passes a
1‑1/2‑inch sieve.\] \[material approved by the Contracting Officer, with
a general size range from 1/4 inch to 1/2 inch (6 mm to 13 mm). \[One
hundred percent of the material shall pass a \[1/2\]‑inch sieve.\] \[Not
more than 5 percent shall pass a No. 8 sieve.\]

D. Sod Materials: Shall consist of the grass mat from a lawn or cultured
grass area, which has sufficient root mat to remain together when rolled
or removed from the trench area. Grass and soil, which will not
reasonably remain intact, shall be considered topsoil.

[PART 3: EXECUTION]{.underline}

3.1 PREPARATION

A. Clearing: \[Maximum clearing width is 4 feet (1200 mm) on each side
of the trench. Provide minimum disturbance to existing grass and sod.
Dispose of debris \[[ ]{.underline}\]. \[Clearing and grubbing shall be
according to Section 02231 ‑ Clearing and Grubbing.\]

B. Sod Conservation:

1\. Sod shall be cut in strips of sufficient width to allow trench
construction without loss of remaining sod.

2\. Sufficient soil shall remain on the root mat to cover the major root
system and assure growth when replaced. In no case shall this mat be
less than 3 inches (75 mm) thick.

3\. Length of sod strip shall be limited to produce a piece that can be
reasonably removed and replaced by one person.

4\. Trench work shall be planned to allow replacement of sod strip
within 72 hours of its removal. Sod shall be kept moist and protected
while removed from the trench area.

C. Topsoil: Strip topsoil, or in the absence of topsoil, strip the top 4
to 6 inches (100 mm to 150 mm) of surface material and store in
designated stockpile areas. Do not excavate into the underlying,
original topsoil at stockpiles. Place previously stripped topsoil onto
disturbed-earth areas upon completion of the backfilling operation.

D. Utilities: Before starting excavation, establish the location and
extent of underground utilities in the work area. Protect active utility
services uncovered by excavation. Notify the Contracting Officer
immediately if utilities are damaged. Damage to utilities shall be
repaired or replaced at the Contractor\'s expense. \[Repair to damaged
utilities shall be started immediately unless otherwise authorized by
the Contracting Officer.\]

E. Cutting Pavement, Curbs, and Gutters: Make cuts with parallel,
straight lines, 1 foot (300 mm) ( wider than trench width on each side
of trenches 1 foot and (300 mm) beyond each edge of pits\].

F. Protection of Excavation: Construct and maintain shoring, bracing,
underpinning, and sheet piling necessary to protect the \[excavation.\]
\[and\] \[adjacent structures.\] Remove protection devices when safe to
do so, or as authorized by the Contracting Officer. Portions wholly
buried by earth and at a distance of at least 18 inches (450 mm) from
permanent structures may be left in place in the completed work. The
exposed portion of the sheeting and shoring must be removed before
completing the backfill.

G. Dewatering: Keep the excavation dewatered so that pipe, forming, and
concrete work can be carried on under dewatered conditions. Dispose of
excess water \[by using natural drainageways near the site to the extent
of their natural capacity, when no erosion or other damage will be
encountered.\] \[in a manner that will avoid damage to adjacent
property.\] \[Contain water on Government property.\]

3.2 INSTALLATION

A. General:

1\. Restore disturbed areas of existing bituminous pavements.

2\. Restore disturbed areas of existing concrete structures.

3\. Do not install bedding material above \[water\] \[electrical\]
\[telephone\] \[and\] \[sewer\] systems until system testing is
completed and approval granted by the Contracting Officer.

B. Trench Excavation: Shall be as \[shown on the drawings.\] \[staked in
the field.\] \[Pipe\] \[and\] \[electrical\] \[and\] \[telephone\]
\[cable\] shall be 5 feet (1500 mm) below natural ground except
drainpipes which are daylighted.\] Excavate trenches in rock to a depth
of at least 4 inches (100 mm), but not exceeding 12 inches, (300 mm)
below pipe bottom.

1\. When over-excavation occurs, repair the area by backfilling with
approved bedding material and compacting to 95 percent maximum dry
density according to AASHTO T 99, Method C.

2\. When frost action occurs, remove frozen soil and replace with
approved soil compacted to 95% of maximum dry density as determined by
AASHTO T 99, Method C.

3\. When soil becomes saturated above the optimum moisture content,
compact after it has dried, or remove soil down to firm material and
place backfill before construction proceeds.

4\. Direct-burial cable trenches shall be excavated 150 mm (6 inches)
below required minimum cable depth. \[Cables shall be installed in
conduit under roads or paved areas.\]

C. Removal of Materials by Explosives: \[The use of explosives to remove
materials, which cannot be excavated without blasting, shall be done
according to Section 02302 ‑ Explosives.\] \[The use of explosives is
prohibited.\]
