The request for field services is the direct responsibility of the
developer or builder and should they neglect to request same (or request
same less than 48 hours prior to need, and field services cannot be
scheduled), all work accomplished without field services will automatically
be considered unacceptable. Extreme care should be taken to avoid
this situation, since:
(a)
All construction not accessible for complete visual inspection
must be reestablished in such a manner as to allow for same before
it will be accepted.
(b)
All construction which is subject to curing and hardening and/or
which must be compacted (e.g., portland cement concrete, bituminous
concrete, backfill, subgrade, etc.) must be tested in such a manner
as to allow for complete evaluation before it will be accepted.
(c)
A complete schedule of the required tests, examinations, etc.,
required in specific instance will be provided by this office.
B.
Owner. The owner's Plant Superintendent shall be notified at least
48 hours in advance that inspection is required. Notification may
be made either in writing or verbally, but in either instance, notification
must be received prior to the said 48 hours.
(1)
Verbal notification shall be made at: (856)461-0700. The request
for inspection is the direct responsibility of the developer or builder
and should they neglect to request same (or request same less than
48 hours prior to need, and inspection cannot be scheduled), all work
accomplished without inspection will automatically be considered unacceptable.
Extreme care should be taken to avoid this situation, since:
(a)
All construction not accessible for complete visual inspection
must be reestablished in such a manner as to allow for same before
it will be accepted.
(b)
All construction which is subject to curing and hardening and/or

normal work hours, all costs will be the responsibility of the property
owner. Additional staff requirements will be determined by the Sewer
Department.
(3)
Any work performed outside normal business hours without proper scheduling
with the Sewer Department must be properly inspected and approved
by the Sewer Superintendent or a designee from his department. In
order to ensure a proper inspection, the Sewer Department can require
the removal of any materials that may be covering the lines that were
worked on by the contractor or homeowner.
(4)
The work site of any emergency work or work done during normal business
hours shall be maintained in a safe condition and free of hazards
to the public. Failure to maintain a safe environment is cause for

normal support grade and refilled with compacted granular material.
(13)
Materials excavated:
(a)
The materials excavated shall be stored compactly on the side
of the trench and kept trimmed to be of as little inconvenience as
possible to travel and adjoining properties. All streets shall be
kept open for travel unless otherwise directed by the Engineer. All
bituminous gravel, stone surface, gravel base course and topsoil shall
be kept separate from other excavated materials and shall be used
as the final layer in the backfill operation where appropriate.
(b)
Before excavating any existing surface, topsoil shall be stripped
to a minimum depth of six inches and stored for reuse as final grade
where planting is proposed.
(c)
The contractor shall not remove from the site any sand, gravel
or other soil excavated from the trench which may be suitable for
backfilling until backfilling is completed.
(d)
Surplus material remaining after the proper backfilling of trenches
shall be used to till in low areas or where shown on the profiles.
Other surplus materials shall be transported and placed by the contractor,
at his expense, at a location within the Township as determined by
the Engineer.
(14)
Removal of water:
(a)
The contractor shall at all times provide and maintain ample
means and devices to promptly remove and disperse all water or sewage
entering excavations and structures dry until all work therein is
completed.
(b)
The contractor shall dispose of the water from the trenches
and excavations in a manner satisfactory to the owner, developer and/or
owner inspector, without damage to adjacent property. In no case shall
water or sewage be allowed to enter new lines. Sewage shall not be
discharged onto the ground or into the stormwater system.
(c)
If groundwater and subsoil conditions along the line of the
work are such that the contractor cannot successfully remove water
or provide a stable trench by ordinary trench pumping and bailing,
or when necessary to protect the work, workmen, public, under- or
aboveground utilities and structures, pavements and public and private
property, the contractor shall, where designed by the Engineer, furnish
and provide the necessary equipment, power and labor to employ the
well point method of trench dewatering. The well point system or portions
thereof shall be removed by the contractor upon the completion of
backfill, and the holes remaining from the points shall be backfilled
and thoroughly tamped.
(15)
Shoring and sheathing:
(a)
The contractor shall be responsible for the installation of
shoring and sheathing on all faces of the excavation where it is necessary
to ensure a suitable, dry, and/or safe excavation, to eliminate settlement
of, or damage to structures or items adjacent to the excavation, to
preserve the bearing capacity of the soil, to keep the excavation
within the narrowest possible limits, to protect work from damage,
and to provide conditions acceptable to the Engineer and all interested
agencies.
(b)
Bracing shall be installed so that there is no stress on or
displacement of any part of the completed work until the construction
thereof has proceeded far enough to provide the necessary strength,
as determined by the Engineer.
(c)
Any damage to pipelines, road structures, etc., occurring through
settlement, soil pressure, cave-ins, shifts of sheathing, or any other
causes associated with the contractor's activities shall be repaired
or the damaged items replaced by the contractor without cost thereof
to the owner.
(16)
Backfill and compaction:
(a)
After each joint has been made, inspected, and approved, backfill
shall proceed immediately. The space between the pipe and the bottom
sides of the trench shall be backfilled by hand and thoroughly tamped
with a light tamper. Fill shall be placed uniformly on both sides
of the pipe in six-inch layers using the material obtained from on-site
excavating, except for the use of select backfill material where indicated
on the plans or as directed by the owner's inspector.
(b)
Backfill to a height of two feet above the top of the pipe with
earth free from stones, rock fragments, dirt clods or frozen material
greater than two inches in largest diameter, and thoroughly tamped.
(c)
The remainder of the trench shall be backfilled in twelve-inch
layers, loose measure, each layer thoroughly tamped. Dampening of
the material to be tamped may be required by the Engineer.
(d)
In light soils such as sand, loam, or light gravel, the trench
may be backfilled carefully with a front-end loader at a maximum rate
of one cubic yard per load. Each load shall be placed immediately
on the previous load.
