1.
General Requirements.
A.
Introduction.
(1)
These specifications cover the requirements construction of
all of the Township's water and sewer line facilities. These specifications
are intended for and apply to all such projects whether directly constructed
by (a) contractor(s) under contract the Township, or constructed by
a land developer who in turn employs a construction contractor(s).
(2)
Where the term "Township" is used herein, it shall mean the
Municipal Sewer and Water Authority of Cranberry Township, its employees,
management, or Board, as is appropriate for each occurrence of use
of the term. When necessary or the Township may call upon its engineering
and/or legal consultants for advice and direction.
B.
Inspection of Construction Work.
(1)
All work performed in connection with the extension modification
or improvement of public water or wastewater facilities within the
Township shall be required to conform with all Township rules and
regulations and shall be inspected during construction by an authorized
representative of the Township.
(2)
All completed work shall be required to meet the approval of
the Township and shall be changed, modified, replaced, removed or
otherwise corrected by the contractor to such extent as directed by
the Township.
(3)
The work will be periodically or continuously inspected during
its progress and when completed, shall be in inspected jointly, by
the Township and the contractor.
(4)
The contractor shall keep on site, and make available upon request
by the Township, a surveyor's rod and level for the purpose of spot
checking elevations as the work progresses.
(5)
The contractor shall also keep and make available a 300 feet
surveyors tape for the purpose of spot checking distances and for
the purpose of the contractor providing off-set measurements as the
work progresses.
C.
Rights-of-Way.
(1)
The alignments and locations of the proposed pipe lines and
appurtenances are shown on the plans on which street, highway and/or
other acquired rights-of-way limits have also been superimposed. No
pipe line shall be relocated outside of the street or other right-of-way
within which it is shown without obtaining the formal written approval
for such chance from the Township.
(2)
Where a special pipe line right-of-way is obtained through private
property, the minimum permanent width for operation and maintenance
purposes shall be 20 feet; the width of the temporary right-of-way
obtained through such private properties for initial pipe line installation
and construction purposes shall be 40 feet, 10 feet of which shall
be located adjacent to and on the outside of both limits of the permanent
right-of-way. The minimum distance between the center of any longitudinal
pipe line and the right-of-way limit line shall be five feet. All
construction activities shall be confined within the 40 feet wide
construction right-of-way as much as possible.
(3)
The contractor shall, however, make his own arrangements for
office space, materials storage yards, change trailers, sanitary facilities,
utility services, debris disposal sites, and for ingress and egress
to any location along the pipe line project for which the contractor
desires or requires use and, for which the Township has been granted
no such right-of-way.
(4)
Proposed pipe lines and appurtenances may also encroach upon,
right-of-way occupied by pipelines or other facilities owned, operated
and/or maintained by other utility companies and/or governmental agencies.
It shall be the responsibility of the contractor to notify the appropriate
representatives of those agencies in advance of performing any work
therein and, to conduct all construction activities in accordance
with the respective regulations appertaining thereto. The contractor
shall utilize the PA One Call System as required by law. The PA One
Call telephone number is 1-800-242-1776.
(5)
The position of water and sewer lines proposed to be constructed
in connection with land development projects shall be such that, regardless
of the sequencing of various utility line construction gas, power,
telephone, water, storm sewer, sanitary sewers, etc. no pipe line
shall be aligned longitudinally, along either the water or sanitary
sewer lines, any closer than three feet. It is imperative that such
minimum distance be maintained along all sanitary sewer and water
lines to provide space required for future maintenance and/or repairs.
(6)
The separation between sanitary sewer and waterline pipe(s)
shall be in accordance with the regulations of the Pennsylvania Department
of Protection, in accordance with Detail Drawing SW-5.
D.
Control of Pipe Line Elevations and Alignments.
(1)
The contractor shall confirm the elevation of all existing facilities
to which proposed facilities will connect, as well as the profile
of the existing and/or finished (in the case of land development projects)
ground lines, prior to commencement of construction, to confirm compatibility.
(2)
All sewer lines shall be required to be constructed and the
elevations and alignment shall be controlled by the use of laser equipment.
Sewer line construction shall begin at the manhole with the lowest
invert elevation unless prior approval is granted by the Township.
Water lines shall be installed on uniform slopes as indicated on the
profiles to assure that the air release valves (where indicated) will
function effectively. Similarly, such grade controls of waterlines
shall also be implemented to assure that blow-off assemblies are properly
located.
(3)
The contractor shall employ competent field survey personnel
as may be required to control grades and/or alignment of proposed
facilities and to assist the Township by obtaining information during
construction progress, and for purposes of preparing as-built record
drawings.
E.
Traffic Warning Signs, Barricades, Lights and Control.
(1)
Where pipe lines and/or other facilities are constructed along
State Highways and/or Township Streets, and where construction activities
may otherwise impede normal vehicular traffic patterns on said highways
or streets, the control of traffic shall be accomplished in accordance
with the details set forth in Publication 203 of the Pennsylvania
Department of Transportation, the title of which is "Work Zone Traffic
Control."
(2)
The position of work zone signs, erection of signs, sizes of
signs, details and configuration of signs, traffic channelizing, tapered
lengths/spacing, cones, drums, vertical panels, lighting devices,
arrow boards and all flagging conduct and activities shall conform
to the details described therein. The location and configuration of
traffic control methods shall conform to those graphically illustrated
on the appertaining Table 5 and Figures 5 through 23 shown in the
publication. The contractor shall submit a traffic control plan and
procedure (conforming to the above referenced Publication 203) to
the Township for approval, prior to commencing with field construction.
F.
Exploratory Excavations.
(1)
Some of the proposed pipe lines and appurtenant structures are
somewhat flexible with respect to alignment. Therefore, in those existing
streets, roadways, berms or other areas expected to have a number
of underground utility lines, where there are large trees which may
be saved by realignment, and where the Township so directs, the contractor
shall make appropriate exploratory excavations for the purpose of
locating said lines.
(2)
In all instances, the costs associated with exploratory excavations
shall be the responsibility of the contractor, and any realignment
of pipelines shall be approved by the Township.
G.
Existing Utility Lines — Location, Protection and Hazards.
(1)
The plans show those underground water lines, gas lines, electric
lines, cable TV lines, telephone lines, sanitary sewers, storm drains,
conduits and other similar utility lines and appurtenances for which
said location information was either made available to the designer,
or was observed in the field. Neither the number of such underground
facilities nor their respective types, sizes and/or locations can
be assured or guaranteed and it is therefore, the responsibility of
the contractor to obtain such additional information; as is required
to properly complete the work in compliance with the specifications,
and to contact the owners of the various utilities in the area prior
to starting and during performance of the work accordance with 73
P.S. § 180.
(2)
The approximate location of any power and telephone poles and
guy poles along the route of the work is shown on the drawings and
the overhead lines supported by all such poles shall be observed and
located by the contractor prior to commencement of the work.
(3)
The contractor shall be completely and solely responsible for
any and all property damages, bodily injuries financial losses and
interruption of service that results from or are attributable to his
construction activities and, which affect water lines, gas lines,
electric lines, telephone lines, drain lines, sanitary and storm sewer
lines and all appurtenances and service facilities connected thereto.
Restoration of all such disturbed facilities shall be accomplished
immediately after incurrence thereto.
(4)
Water, sewer, gas, power and telephone service to dwellings
or places of business shall be maintained with a minimum of interruption
throughout the construction of the contract work. No such service
shall be intentionally interrupted without the approval of the respective
utility company concerned, and without first giving due warning to
the occupants of said dwelling or business establishment. At least
three working days notice of an interruption in service shall be given
to the Township so that the Township may notify its customers.
(5)
In some areas, it may be found that existing pipe lines are
in a location where construction of the proposed work cannot reasonably
proceed until the utility has been relocated. The contractor shall
make all necessary subsurfaces investigations and shall locate such
utility mains far enough in advance of the trenching work so that
work progress is not unnecessarily interrupted.
(6)
Attention is directed to the fact that the proposed work could
be in close proximity to overhead power lines which transmit electric
current at high voltages and which, if disturbed or contacted during
construction, would be hazardous to construction personnel and/or
other persons. The contractor shall, therefore, properly protect such
wires, pole supports or other power line appurtenances to avoid disturbance
to those facilities, and shall operate all machinery and conduct all
other construction activities in a manner which will assure protection
of all construction personnel and other persons against said hazards.
(7)
Work in the vicinity of the existing underground gas lines and
appurtenances is also hazardous because under certain conditions,
such materials are flammable and/or explosive and, the contractor
shall avoid all temporary and permanent supports and other required
protection to prevent exposure of the same to construction personnel
and/or other persons. Where such lines are exposed during construction
and leakage is detected, construction work in those areas shall be
immediately suspended, the owner of the pipe lines shall be immediately
advised of the condition and the construction work shall not resume
until all repairs have been properly completed.
(8)
The construction activities required to be performed in the
conduct of the work may necessitate the interconnection, interception,
surveying, inspection, removal, replacement and repair of certain
existing manholes, sewer pipes and appurtenances. Said items are conveying
all wastes and runoff discharged to and infiltrating into the public
sewer system within the area served, which wastes may contain and/or
generate toxic, noxious oxygen depleting or other liquid or gaseous
substances harmful to human beings.
(9)
The contractor shall also provide all personnel with all tools,
clothing and other devices necessary for such safe practice, including
appropriate waterproof clothing, respirators, protective glasses,
mechanical air blowing equipment to pre-ventilate manholes and other
chambers, explosive atmosphere detectors, ladders, safety harnesses,
etc. No work shall be performed under any unsafe conditions and if
same is detected at any time, the contractor shall, therefore, thoroughly
instruct all personnel involved in such work so that appropriate and
complete safety practices are observed at all times.
2.
General Notes.
A.
Shop Drawings.
(1)
Prior to delivery to the job site, the contractor shall supply

other areas where construction equipment and activities impose damage
to ground surfaces shall receive six inches of screened topsoil.
(4)
After the topsoil has been spread, all lawns shall be restored
by raking the area disturbed by construction. An application of an
approved fertilizer at a rate of 50 pounds per 1,000 square feet shall
be made. Said area then shall be completed with peat moss, mushroom
manure or other approved grass seed shall be sown. The contractor
shall be responsible for restoration of all settlements and for properly
preparing the topsoil, applying fertilizer and mulch and planting
the seed, but will not be responsible to water those restored areas.
(5)
All shrubbery which is removed temporarily to accommodate construction,
shall be promptly replaced after backfilling is completed and shall
be fertilized and otherwise treated to insure restoration to a condition
existing prior to construction.
(6)
Shrubbery which is not successfully removed and replaced, shall
be placed by the contractor for the period of 18 month maintenance
bond.
(7)
