4 SPECIAL PROVISION PRIMARY ELECTRICAL SERVICE DISTRIBUTION SYSTEM 4/11/2013 PART 1 GENERAL 1.01 SECTION INCLUDES SCOPE OF WORK 1.02 Scope of Work A. This work consists of designing and constructing a Cleveland Public Power Underground Primary Electrical Service Distribution System replacement, at the locations shown on the drawings and as described below. The Contractor shall furnish all labor, plans, drawings, design calculations and all material and equipment required to design and construct the Primary Service Line Replacement in accordance with this Specification. The replacement concrete encased duct bank will consist of a series of 6 foot x 12 foot x 7 foot standard CPP Manholes with a 6 5 PVC concrete encased duct bank. The duct bank will commence at the existing CPP manhole located in the Southwest corner of the intersection of Father Frascati Drive and W. 73 rd Street, extends north along W. 73 rd Street through the railroad underpass and then east to interface with an existing CPP manhole located adjacent to the bridge abutment along Edgewater Drive. B. Work will include the removal, and replacement of existing CPP primary electrical facilities, both aerial and underground at the following locations: 1. Aerial service beginning from a wood pole at the intersection of W. 70 th Street and Father Caruso Drive (W. 70 th Street, Sta Lt.±), crossing over Father Caruso Drive to a wood pole located at Father Caruso Drive, Sta Lt.±. 2. Aerial service from the intersection of W.70 th Street and Father Caruso Drive, (Father Caruso Drive, Sta Lt.±), crossing north over the Norfolk Southern Railroad tracks to a wood pole located at Father Caruso Drive, Sta Lt.±, and traversing down the hillside to a wood pole located along Eastbound Exit Ramp Four of the West Shoreway /Edgewater Drive Interchange (Pathway, Sta Rt.±). At this service pole the aerial service transitions to an underground duct bank to an adjacent manhole (Pathway, Sta Rt.±). 3. Underground facilities from the adjacent manhole located along Eastbound Exit Ramp Four of the West Shoreway/Edgewater Drive Interchange (Pathway, Sta Rt.±)., extending to an existing manhole located adjacent to a bridge abutment at the intersection of Eastbound

5 Exit Ramp Four and Edgewater Drive (Edgewater Drive, Sta Lt. ±) passing through a second manhole located on the right side at the end of Eastbound Ramp Four (W. 73 rd Street, Sta Rt. ±). 4. The aerial service located along the left side of Father Caruso Drive between W. 67 th Street and W. 70 th Street will require removal to permit the construction of temporary railroad tracks, to shift the railroad alignment south to permit construction of the proposed W. 73 rd Street railroad overpass structure. CPP will install a temporary aerial service feeder to replace the section of aerial feeder between W. 67 th and W. 70 th Streets. Upon installation of the temporary aerial feed by CPP, the existing aerial service will require removal. Coordination with CPP will be required. 5. All proposed work will be coordinated with, and approved by CPP prior to any construction work beginning. 6. The 6 5 concrete encased duct bank shall be installed a minimum of four feet in depth below top of grade/top of roadway sub base. A minimum of 1 foot of clearance will be required between the duct bank and all other utilities. Any deviation from the minimum depth and minimum clearance between the utilities must be coordinated and approved by CPP prior to any construction work beginning. 7. Coordinate with CPP for manhole and duct bank details and requirements. 8. The removal and relocation of an existing aerial/underground telecommunications line following a similar alignment with the electrical primary service is required. The design/build status of this work will be determined during construction and is not included with this work. The contractor will contact and coordinate with the appropriate telecommunications company for guidance on the removal and relocation of this line. Any required work will be coordinated with the Engineer for direction. C. Subsequent to Notice to Proceed and prior to beginning any design and/or construction work on the Primary Electrical Service Distribution System, the Contractor shall schedule a Site Visit and Pre Design Meeting with Cleveland Public Power to review and coordinate all of the work required and have a full understanding of Cleveland Public Power s standard requirements and specifications for the work involved. Cleveland Public Power s standard specifications and requirements will supersede any requirements and conditions outlined in this specification. Additional information and/or standard details not included with this Special Provision may be provided by Cleveland Public Power for compliance with their standard requirements. The proposed primary service duct bank design must be submitted to ZCPP for their review and approval. Shop drawings of all required materials must be submitted to CPP for their review and approval.

6 D. It may be necessary to employ the services of Norfolk Southern flagmen to cover the work requirements on and/or adjacent to Norfolk Southern property. Coordinate with Norfolk Southern the project design and construction requirements to determine the requirement for Norfolk Southern flagmen. Cost for the flagmen will be part of the bid cost. Separate payment will not be made PRE APPROVED LIST A. The prime Contractor must select one of the specialty contractors prequalified with the Department per the Ohio Revised Code through and shall identify the specialty contractor on his proposal at the bid opening. No substitution will be permitted without written approval of the Engineer. Substitution after the bid opening will not be grounds for changes in bid prices AVAILABLE INFORMATION A.

31 CPP CONSTRUCTION NOTES Contact Ohio Utilities Protection Service, two working days prior to start of construction. In Ohio, call toll free It's The Law. All power conduit runs are to be constructed by using 2", 4", 5", or 6" pvc schedule EB conduits, encased with a 3" concrete envelope, unless otherwise noted. The concrete envelope is to be 4000psi (City of Cleveland Concrete Mix). A rugged polyethylene material warning tape capable of resisting high or low ph conditions must be placed above the electrical conduit bank. This warning tape is to be six inches wide, red in color, and imprinted with the words, "DANGER - BURIED HIGH VOLTAGE CABLES BELOW". This tape is to be placed 6" above the newly installed duct bank. This shall conform to the standards as set by Ohio Utilities Protection Service. As an option, contractor may elect to encase CPP's conduits in red concrete. Both methods are approved by Cleveland Public Power and are recommended by Ohio Utilities Protection Service. All conduits runs are to be installed at a minimum depth of 2'-6" below the existing and/or proposed grades, or as shown on the profile sheets, except those that are under any railroad or RTA tracks. The conduits will be installed at a minimum depth of 60" below the rail ties. Also, at any railroad crossings, conduits are to be encased in a steel pipe. See drawings issued by Cleveland Public Power for details. Vertical and horizontal curves shall have a minimum radius of no less than 30 feet. These curves are to be constructed by using the appropriate 5 couplings, and associated chord lengths of conduits as noted on the plan view and/or as shown on the Conduit Curve Construction Chart. Any other curve design, field changes, or the use of preformed radius bends must be approved by the Engineering Department of Cleveland Public Power. All manhole outside walls and conduits runs are to have a minimum clearance of 5' (face to face), horizontally from all water lines. Vertical clearance shall be at a minimum of 1'-6", or as shown on the profile sheets of the project. Clearance between other utilities shall be 1, unless noted otherwise. CPP's duct bank shall cross over or under other utilities at an angle of no less than 45. Any conduit runs that are crossing any steam lines shall have a minimum clearance of 5', or as shown on the profile sheet of the project. In the event that this cannot be accomplished, notify the Engineering Department of Cleveland Public Power prior to the installation of our conduits. Each newly constructed manhole shall be free of all foreign objects and debris. The contractor shall also provide a pulling line in each of the new conduits. All manhole covers should be inscribed with the Cleveland Public Power logo "CPP". The contractor shall provide Cleveland Public Power with as-built plans of the newly installed conduit system, showing both vertical and horizontal locations. These locations shai1 be at 50' intervals. All elevations are to be based on Cuyahoga County Regional Geodetic Surveys. Page 7 of 20
