SANITARY SEWER IMPROVENKNPS
FOR THE
CITY OF ROXBORO. NORTH CAROLINA
DETAIL SPECIFICATIONS

General - The City of Roxboro proposes to construct an eight (8) inch
polyvinyl chloride sanitary sewer south of Stephens Drive as shown on
Engineer's Drawing 95-40 and in accordance with these Detailed
Specifications. All work will be performed with City personnel and
equipment. In general. approximately 1.057 linear feet of eight (8)
inch FVC pipe will be installed from a saddle manhole installed over
an existing 21 inch PVC interceptor along Marlowes Creek and extend
east along a tributary to Marlowes Creek to serve lots along Stephens
Drive. Pipe, manholes. silt fences, rip-rap and other appurtenances
will be installed as indicated on the Drawings. A Detail Sheet along
with a Cover Sheet have been prepared by the Engineer for this
project. These Drawings, along with the Specifications herein.
indicate the scope of the work and the quantity and quality of
materials necessary for the construction of this project.
' The City of Roxboro will locate and uncover all services and pipe
line crossings for all utilities and storm drainage ahead of
construction to permit adjustments to the grades of the proposed
construction. Should any utility be damaged during construction, such
as to cause leaks or jeopardize public safety, the City of Roxboro
will immediately repair the utility before continuing construction.
Field surveys conducted by W. M. Piatt and Company did not indicate
any existing underground utilities other than the interceptor along
Marlowes Creek that would be encountered during construction.
' The City of Roxboro will handle the construction work in such a
manner as to maintain traffic along Stephens Drive for the purposes of
delivering machinery and equipment and will provide, erect, and
maintain the necessary adequately worded signs, barricades. suitable
' and sufficient lights, and danger signals in substantial conformance
with the Manual on Uniform Traffic Control Devices for Streets and
Highways, as published by the Bureau of Public Roads; and provide, if
necessary, a sufficient number of watchmen to take all necessary
precautions for the protection of the work and the safety of the
public.
' The North Carolina Sedimentation Control Act of 1973 will be
complied with during the construction of this project. All creek or
ditch crossings will be rip-rapped as shown on the Drawings. Silt
fences will also be installed in locations as shown on the Drawings.
' Seeding and mulching as hereinafter specified will be accomplished as
soon as possible after areas of construction are completed. All work
' areas will be cleaned after each days construction to prevent any
deposition of silt during a rain. State personnel inspecting erosion

control will have access to the site.
All necessary alignment and grade stakes for the construction of
the proposed work will be established by the Engineer. Easements to
the widths shown on the Drawings will be obtained by the City of
Roxboro for the purposes of construction and long term maintenance.
All work will be confined within the defined permanent and temporary
easements so as not to disturb or destroy private property.
The proposed gravity PVC sanitary sewer will be installed to
location, elevation, and grades as shown on Drawing 95-40 and as
hereinafter specified:

and outlets will have flexible rubber sleeve boots cast in place. All
manhole bottoms will be built-up using Class "C" concrete forming an
invert and flow line through the manhole as shown in detail on the
Drawings. Inverts will be trialed smooth free of any burrs that may
trap debris or retard the flow of wastewater through the manhole.
A "Saddle-Type" Manhole with a flat top will be installed over
the existing 21 inch interceptor along Marlowes Creek. This manhole
will be four (4) feet in diameter and conform to all related standards
hereinbef ore specified for concrete manholes. The top of the manhole
will extend three (3) feet above existing ground elevations with a
four (4) inch ductile iron vent extending one (1) foot above the 100
year flood elevation of 554.00. The ductile iron vent will conform to
2

ANSI Specifications A 21.51-1986 and be tar coated. The pipe will be
Class 50 wall thickness in accordance with ANSI Specification A 21.50
latest revision. Connections will be flanged manufactured per ANSI
A21.15-83 and will be standard Class 125 per ANSI B16.1. All flanged
' connections and fittings for the four (4) inch ductile iron vent will
be installed as shown on Drawing 95-41 for the "Saddle-Type" Manhole.
Prior to setting the "Saddle-Type" Manhole, a six (6) inch
concrete foundation will be poured underneath the existing 21 inch
interceptor. The foundation will be poured using Class "A" concrete
' reinforced with Grade 60 deformed steel bars meeting the requirements
of ASTM Specification A 615-81a.
Manhole Frames and Corers - All manhole frames and covers, except for
' the "Saddle-Type" Manhole, will be Dewey Brothers Model 2001 with
perforated covers with four (4) vent holes. The minimum average
weight of all vented manhole frames and covers will be not less than
310 pounds. All manhole rims and covers will be machined at contact
'
points to make an even and smooth contact between rim and cov er. The
words "Sanitary Sewer" will be cast on the sewer manhole covers.
Frames and covers will be thoroughly cleaned of slag, etc.... and will
be coated with a hot application of quick drying asphalt base dip.
The frame and cover installed for the "Saddle-Type" Manhole will
' be a Dewey Bros. MH-RCR-17 B. The frame and cover will have a minimum
average weight of 256 pounds and sealed watertight by the use of a
rubber gasket and 4-5/8 inch stainless steel bolts. The words
' "Sanitary Sewer" will be cast on the cover. The frame and cover will
be coated with a hot application of quick drying asphalt base dip.
Manhole Steps - Manhole steps will be composite polypropylene plastic-
steel construction. All manhole steps will be reinforced with a No. 3
deformed steed rod. Plastic manhole steps will be those manufactured
by M. A. Industries. Inc.. or equivalent.

Trenching - All trenches will be open cut from the ground surface on
line as shown Drawing 95-40. No trench in advance of pipe laying
operations will be opened than is necessary to expedite the work. The
trench will have a minimum width of 16 inches plus the outside pipe
diameter and the maximum width of the trench at the top of the pipe
will not be more than 24 inches plus the outside diameter of the pipe.
Trenches will be excavated below the pipe invert a sufficient distance
to provide space for stone bedding as required by field conditions and
as hereinafter specified. Bell holes will be excavated at each pipe
joint to prevent point loading at the bells or couplings.
The width of the trench in rock excavation will be two feet
greater than the nominal diameter of the pipe. All trench rock
excavation will be carried six inches below the invert of the pipe.
The excavated area will be brought back to grade with crushed stone.
All trench rock will be disposed of off-site. Select compactible fill
material will be brought to the site as acceptable backf ill for the
replacement of trench rock.
3

' Backfilling - After the pipe has been laid. backfilli.ng will be done
as follows: Backf filling along the sides of the pipe above the spring
line and to a level 12 inches above the pipe will be carefully done by
hand using select material placed in layers not more than 6 inches
thick and thoroughly compacted with mechanical tamping equipment using
care to insure that pipe alignment and grades are not disturbed.
Except for line in drives or paved areas as hereinafter specified,
' backfilling from this elevation up may be placed in layers not
exceeding 12 inches thick, kept reasonably level and compacted to 90%
of maximum density as determined by ASTM Specification D698-70
(Standard Proctor Test). Should settlement occur, the City of Roxboro
will bring the ditch back to grade, including reseeding as necessary.
Backfill will not be permitted when trenches are flooded. or
material is too wet (or dry) for proper compaction.
1
All blasting operations will be conducted in strict accordance
with existing ordinances and accepted safe practice relative to the
storage and use of explosives. Blasting will be done only by
experienced men. and extreme care and precautions will be used to
prevent injury to workmen, to the existing pipes, buildings. or other
structures either below or above the surface of the ground.
Sufficient warning will be given to all persons in the vicinity of the
blasting.
In trenches with unstable bottoms, crushed stone will be placed
under and around the pipe as necessary for a stable trench.
All trenching operations will meet or exceed OSHA requirements
for shoring, blasting, and the safety to the workers. It will be the
responsibility of the City of Roxboro to be knowledgeable of these
requirements and to implement such OSHA regulations during
construction and trenching operations.

Stone bedding will be required under all laying conditions. A
minimum of six (6) inches of stone will be placed under the pipe in
order to provide uniform bedding. Stone will also be placed along the
sides of the pipe to the spring line. All stone bedding used will be
3/4 inch. No. 57 stone.
In trenches with unstable bottoms, the Engineer may require the
pipe to be supported in concrete or by additional stone bedding to
depths underneath the sanitary sewer approved by the Engineer. Where
the bottom of the trench is in unusually poor soil which will not
support the weight of the pipe and which cannot be properly
reinforced by the addition of stone. the pipe will be supported by
creosote timber as directed by the Engineer.
Pipe and Pipe Laying - All materials. equipment, and labor for laying
and j oining the pipe in the trench will conform to these
specifications will be furnished by the City of Roxboro. The City of
Roxboro will have an experienced pipe man in charge of all pipe work.
Pipe laying in general will be in accordance with ASTM Specifications
1 C12-72.
No pipe will be laid within ten feet of excavation in earth or
within thirty feet of rock which must be blasted for removal. The
open end of all pipes will be plugged when pipe laying is not in
progress, and all pipe will be protected against injury from falling
' rock when blasting.
Prior to being lowered into the trench, each pipe will be
inspected by the pipe foreman with all faulty pipe rejected and
' removed from the jobsite. Each joint of pipe will be placed in the
trench with the bell end upgrade. The barrel of the pipe will be
uniformly supported on the foundation. Joints will be made-up as
' recommended by the manufacturer of the pipe.
