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.
