Trenching and Silt Fencing:
For Pipe Trenches:
a. Excavate trenches to true line and grade as shown on the Contract Drawings, except where
field adjustments are necessary to avoid other underground utilities. All alignment changes
shall be subject to the Engineer's approval.
b. Accomplish trench excavation with equipment suitable for this type of service. If backhoes
or drag lines are used, the size of bucket must be such that the width of trench excavated is
compatible with the diameter of pipe to be installed.
c. Construct sides of the trench as near to vertical as possible, taking into consideration the
type of soil encountered, applicable safety requirements, and the width of area in which the
lines are installed. Operations resulting in wide top dimensions sloping directly to the pipe
shall not be permitted. Trench width from a point one (1) foot above the crown of the pipe
to the bed of the trench shall not exceed the diameter of the pipe bell plus 12 inches on
each side of the bell unless special permission of the Engineer is secured.
d. Excavate the bottom of the trench to assure a firm bearing support uniformly throughout
the length of the pipe. Excavate a space under and around each bell to relieve it of any
Ioad. Blocking under the barrel or bell will not be permitted. Where ground water
conditions are encountered, the Engineer may require dewatering equipment to be
provided.
e. Remove rock or boulders encountered in the bottom of the trench to a depth six (6) inches
below the grade of the pipe. Place a suitable tamped foundation of earth material to bring
the bottom of the trench to proper sub -grade over rock or boulders.
£ When unstable conditions are encountered at the invert elevation of the pipe and
dewatering or similar measures will not prevent or cure this condition, suitable stabilization
material shall be placed in the trench.
g. When pipe laying is not in progress, plug the open end of the pipe to prevent entry of water,
dirt, tools, or other foreign platter into the pipeline. Do not use the pipe as a means of
carrying groundwater away from the work area.
2. Temporary Silt Fence:
a. Filter fabric to be of polypropylene, nylon, polyester, or polyethylene yard with a minimum
standard strength of 30 pounds per linear inch, a minimum 85 percent filtering efficiency,
and a minimum slurry flow rate of 0.3 gallons per square foot per minute. Fabric should
contain ultraviolet ray inhibitors and stabilizers to provide a minimum construction life of
six (6) months.

linear foot steel. Wood shall be a minimum six (6) feet in length, and steel posts shall be
at least five (5) feet in length.
c. Install silt fence on low side of stockpiles and undeveloped right-of-ways, parallel to
surface waters, and in locations shown on the Contract Drawings. Extend fence around
approximately 90 percent of the perimeter of the stockpile.
d. Construct silt fence as shown on the Contract Drawings.

barricading should include posted warning lights.
3. Protect existing structures, utilities, sidewalks, pavement, and other facilities from damage
caused by settlement, lateral movement, undermining, washout, and other hazards created by
earthwork operations. Protect root systems from damage or dry -out to the greatest extent
possible.

construction drawings regardless of character of materials and obstruction encountered. In the
event that rock is encountered, the Contractor shall remove it at no additional cost to the owner.
7. Stability of excavations shall be maintained by sloping of the sides and shall comply with local
codes, ordinances, and requirements of agencies having jurisdiction_ Where space restrictions
prevent sloping of the sides, shoring and bracing of the walls shall be employed in full
compliance with OSHA requirements_ In the case of pipe installations, sheeting shall remain
in place until backfilling progresses to a stage where no damage to the pipe will result from
removal.
The Contractor shall attempt to prevent surface and subsurface water from flowing into
excavations. The Contractor shall provide equipment, materials, and work necessary to
dewater any accumulation of water in the excavation to prevent softening of the soils,
undercutting of footings, and changes to the soils detrimental to the stability of the
improvements_

avoided as a result of subsequent methods of compaction. Extreme care shall be exercised in
backfilling operations to avoid displacement of pipe and structures either horizontally or
vertically. Backfill consolidation by ponding water is not permitted. Compaction of each layer
of backfill and the top 6 inches of subgrade shall achieve a 90 percent maximum dry density
as measured by AASHTO method T-99.

This control panel is for timed dosing applications. When
the timer enable float is up, the timer will start timing for the
duration of the "Off' time and when complete, the pump will
start for the duration of the "On" time. Both Off and On
times are adjustable. This pattern repeats until the timer
enable float lowers and turns off. The Low float acts as a
redundant of and will also activate the alarm. If the level
reaches the High float switch, the alarm will activate.
