INSTALLATION OF PRECAST CONCRETE CONDUIT 1.0 SCOPE This specification describes the method for installing precast concrete conduit. 2.0 APPLICATION This specification applies to all Con Edison districts. 3.0 GENERAL

This specification provides for the installation of underground precast concrete conduit suitable for the housing of electric cable. These conduits shall be used and installed by Company forces and contractor personnel for new work and for replacement of conduit.

4.0 DEFINITIONS

4.1 Bend - Any change in the direction of the conduit center-line in the horizontal,

vertical or any intermediate plane is to be considered as a bend if the change in direction is greater than 5°.

4.2 Offset - Any displacement of the conduit center-line parallel to itself is to be

considered an offset.

4.3 Dip - A dip is a double offset, the second of which returns the conduit center-line to its original alignment.

5.0 MATERIAL

5.1 Straight Sections - The conduit material shall be in accordance with Con Edison specification EO-1042. The conduit shall be of a square external cross section and shall have a concentric bore and dimensions as per drawing EO-7875-D.


4

5.0 MATERIAL (Cont'd)

5.2 Bends - Bends shall have a concentric bore and square external cross section along their entire lengths and dimensions as specified on drawing EO-9489-C. The 20 foot radius bends shall be used for primary cables. When field conditions prevent the use of 20 foot radius bends, 10 foot radius bonds may be substituted. The use of 5 foot radius bends shall be restricted to service or mains cables, or primary cable from a street trench to a sidewalk transformer vault. The 3 foot radius bends shall be limited to use on intervault ties.

5.3 Split Conduit - When a conduit is field split for installation around existing cable,

either singly or in banks of conduit, it shall be secured as shown on drawing EO-9138-C. Two clamps or straps shall be used per conduit length. When clamps are used, the bolt of the clamp shall be faced in a direction so as not to interfere with any adjacent conduit. Stainless steel ties (EO-100,612) can be used as alternates to the clamps. The maximum length of a split conduit run shall be 75 feet.

5.4 Couplings - The conduits, which are double male end types, are joined with a force

fit plastic coupling as per EO-1179. The plastic coupling, when used for split conduit, shall be cut and wrapped around the ends.

6.0 TRENCH PREPARATION

6.1 Excavation of the Trench - The trench shall be excavated so as to provide a nominal cover of 24" over the highest conduit. The bottom of the trench shall be graded smooth and tamped to minimize initial settlement and to avoid "point" support of conduits. All stones projecting into the trench bottom shall be removed, and the voids backfilled before conduits are placed. Where streets are not to final grade, the cover shall be measured from the final grade, or the existing grade, whichever provides the deeper trench. If due to subsurface conditions the cover is less than 20", the duct shall be protected by 3/8" steel plates the same width as the trench. Adjacent plates shall overlap by two inches. Where possible, provide a 4" layer of clean, well-tamped backfill (Type 3/8" as per EO-8085) between the plate and the top of the duct bank. Trench widths shall be in accordance with EO-7907-D.


5

6.0 TRENCH PREPARATION (Cont'd)

6.2 Rock Protection - In rock excavations, the conduits shall be bedded as per the procedure in Con Edison specification EO-1181.

7.0 INSTALLATION

7.1 Material Inspection - Prior to installation, an inspection of the general conduit condition shall be made by the installing party, whether it be Company forces or contractor personnel. The inspection will include a random check of sections with a mandrel.

7.2 Alignment - The conduit shall be laid in as straight an alignment as possible

maintaining concentric bore and flush joints to permit smooth, easy pulling of cable without damage. A maximum permissible offset of 3 inches in any 4 foot of length will be accepted. Standard precast concrete bends shall be used in all cases where greater changes in alignment are necessary. Double male end joints shall have the plastic couplings forced on snugly to provide a tight seal. All bends shall be laid so that they are tangent at the point of joining. Care shall be exercised to prevent the introduction of foreign material.

7.3 Formation - The conduits shall be laid in the trench in the recommended formation,

specified on drawings EO-7326-B, EO-5571-B and EO-7907-D and as directed by specific layouts. When two or more conduits are installed in a duct bank, the joints must be staggered a minimum of 4 inches, both in the horizontal and vertical directions. When changes in the formation of a bank of conduits within a duct run are necessary, the transition shall be accomplished in as straight an alignment as possible, maintaining continuous earth support under the conduits.

Where specified, gas mains and precast concrete conduits shall be installed in a common trench with clearances as shown on EO-5571-B.


6

7.0 INSTALLATION (Cont'd)

7.4 Construction of Dips and Offset - An offset in any plane of more than 4.6" is to be made by means of 20 foot radius bends. A maximum of three, 20' radius, 5.625° precast bends are used to change the direction of the duct line, followed by a number of tangent sections of conduit to obtain the required distance of offset and three 20' radius, 5.625° precast bends to return the duct line to a direction parallel to its original direction. Drawing EO-9706-C shows the method of making duct deviations for dips and offsets. The approximate values of the offset and required horizontal distance from the start of the offset to the point of maximum deviation are given for a few possible combinations.

7.4.1 An offset of 4.6" or less may be made by cocking the straight sections of

conduit. However, the misalignment of each 4' conduit section is to be limited to 3" as measured at the outer end of the section being installed and at right angles to the projected center-line of the previous section of conduit.

7.5 Points of Entry - Bell end conduits (EO-9799-D) shall be used as the terminal

conduit sections for smooth, precise entry into the manhole wall and carefully cement-grouted into position, as indicated on Drawing EO-9508-C.

7.6 Closing - Closing a section of conduits with double male type ends shall be

accomplished by the use of adapters. Each adapter has a female end which shall be with a section of straight PVC or fiberglass not longer than 1 foot in length and of the same nominal diameter as the conduit in the run. The PVC or fiberglass conduit shall be encased with a concrete protective coating at least two inches thick.

8.0 BACKFILL - The material, procedure, and testing shall be as described in Con Edison

Specification EO-1181. 9.0 INSPECTION AND ACCEPTANCE

9.1 Specification EO-1063 gives the procedures to be followed and the requirements to be met for acceptance of the conduit system.

9.2 Any method used to clean the conduit must be accomplished in a manner that will

not damage the smooth bore. Any damaged conduit must be replaced with new conduit.


7

10.0 REPLACEMENT

10.1 Vacant Duct - Repairs to conduits shall not be permitted. All individual damaged or impaired lengths of conduit shall be removed and replaced with new conduit meeting specification requirements.

10.2 Loaded Duct - Replacement of conduits which are removed from around existing

cables shall be accomplished with precast concrete conduit, field split. Couplings for the field split conduit shall be cut and installed as stated on paragraph 5.4. PVC snap together split conduit as replacement conduit shall be limited to primary cable and it shall be concrete encased.

10.3 Adapting - Joining precast concrete conduit with conduits of other diameters or

material is not recommended. In exceptional cases where this cannot be avoided, use concrete adapters, as per EO-1042, for this transition.

11.0 PULLING LINES – Pulling line installation is described in Con Edison specification EO-

1063. 12.0 PLUGS - Duct ends that do not terminate in manholes or service boxes shall be closed

with duct plugs as shown on drawing EO-10864-D. Plugs should be installed at the end of each day's work to prevent entry of foreign material.

All fittings, adapter, expansion joints, and bends shall be fabricated of the same filament wound material as the conduits. All joints shall use manufacturer approved adhesive and application procedures. Pullout strength of all joints shall meet or exceed the axial pull requirements of NEMA TC14, latest edition, “Joint Separation”.

6.0 ANCHOR/SUPPORT REQUIREMENTS

The span between supports shall comply with the conduit manufacturer’s loading specifications, based on the heaviest primary cable used within the Con Edison system. All supports are to be mounted to existing bridge structural members using galvanized fasteners (HDG per ASTM A123 or A153). Welding to bridge structural members is not permitted. The use of anchoring systems, such as concrete expansion bolts mounted to the underside of the bridge deck, is not permitted. The support configuration and bracing system shall be designed for appropriate dead loads, live loads, wind loads, and axial sliding friction loads from thermal expansion/contraction, and also due to cable pulling operation. Cable pulling loads shall be calculated as per EO-1090. Configurations of supports are to be selected as to minimize bending at the mounting hardware and interface with the bridge structural member. All support design configurations shall be submitted to Con Edison Engineer for review and approval.



7.0 EXPANSION JOINT REQUIREMENTS

For bridges with spans between 200 feet and 400 feet, two expansion joints are required. One located at the center of each half section of the bridge.

PREPARATION OF CONDUIT FOR CABLE INSTALLATION

1.0 SCOPE

This specification covers the preparation procedure to be followed prior to the installation of distribution cable in underground conduit systems.

2.0 GENERAL

The operation described herein shall be followed prior to the installation of distribution cable in conduits.

3.0 OPERATION SEQUENCE

3.1 The following sequence of operations shall be employed as specified below 3.1.1 Previously unoccupied conduit Perform operations 3.2 through 3.6

inclusive 3.1.2 Previously occupied conduit Perform operations 3.3 through 3.6

inclusive

3.2 Operations

These operations may be performed by either Company or contractor forces as necessary.

3.2.1 Rod duct 3.2.2 Brush duct

3.2.3 Clean duct

3.2.4 Perform mandrel operation

3.2.5 Install 1/2" steel rope, 9/16” steel rope or 1/4" polypropylene rope

3.2.6 Secure poly rope in structure




3.3 Duct Roddinq

Rodding is performed from the duct entrance in one structure to the corresponding duct exit in the next structure on the conduit run

3.3.1 Rodding serves to:

a. Establish that a clear passage through the conduit exists between adjacent structures.

b. Provides a means of installing various lines to perform subsequent

cleaning, mandreling, and cable pulling operations.

3.3.2 Rodding operations are performed either manually or by means of vehicle mounted power systems. Manual operations utilize continuous long length (600') fiberglass snakes or segmented fiberglass rods.

3.4 Brushing

Brushing is performed to remove any soil or debris that might have entered the duct since it was installed. This could occur during initial backfilling operations or during the service life of the installation as groundwater washes soil through the duct system. While individual deposits of this soil may be minor, it is removed to prevent accumulations at the nose of the cable during installation operations. This pile up may be so severe as to wedge the nose of the cable tight enough to obstruct the duct. The brushing operation will continue to the extent necessary to ensure free passage of the mandrel. All brushing will be performed in the direction of the cable pull.

3.5 Cleaning

When accumulations of soil and debris are such that the rodding device cannot pass from one structure to another, a water jetting operation shall be employed. A source of pressurized water is connected to a hose line that terminates in a nozzle assembly. This nozzle is fed into the conduit to the point of the obstruction by means of a rod or snake. The water supply is then turned on and allowed to impact upon the blockage and wash the accumulated debris away. Once the debris has been removed or softened, the rodding device or snake can be passed through and the conduit cleaned in the normal manner.




3.6 Mandrel

3.6.1 The purpose of the mandrel operation is two fold

a. Establish that a specific size passageway exists from one end of the duct to the other.

b. Establish that the alignment of the duct is such that horizontal and

vertical bends meet the specified minimum radii requirements.

3.6.2 Use of Mandrels

a. The first consideration should be the length of the cable pull. If an extra long pull (greater than 550 feet actual length) is planned, the conduit system must be aligned so that the 20 ft. radius mandrel will pass.

b. After length, the next most important factor is cable size; large

cables require better conduit systems. Large cable in a fairly long pull (300-500 feet) also requires a near perfect system (passing the 20 ft. radius mandrel).

c. Cases where the conduit system is under 300 ft. long and the cable

is large or the system is from 300 to 550 feet long even with small cable require the 10 ft. radius mandrel to pass.

d. Short pulls and small cable only require the passage of the flexible

mandrel.

3.6.3 Care shall be taken to monitor both travel speed and the line tension so as to assure that any obstructions may be noted and that no damage is done to the duct.

3.7 Final Actions

Upon completion of the mandrel operation the following action shall be taken: 3.7.1 If cable pulling operations are to be performed immediately, ½ inch

steel rope or 9/16 inch steel rope pulling line shall be installed in the conduit.




3.7.2 If the cable pulling operations are to be performed at a later time, a ¼ inch polypropylene rope shall be installed in the duct and properly secured in each structure. Duct entrances shall be plugged with polyethylene plugs.

SECTION I – GENERAL REQUIREMENTS

1.0 SCOPE

The scope of this document is a general guideline for the prevention of damage to high pressure pipes and coating for underground 69, 138 and 345 kV cable systems (electric facilities), caused by construction on (“outside plant”) properties not owned by CECONY. The guideline provides information such as:

a) general instructions and notification requirements prior to any construction activities; b) clearance requirements; c) precautions/protections to be made; and d) special notes during construction activities

The guideline is not applicable for solid dielectric or self-contained oil-filled cables. Specific work plans for these type of Transmission Feeders shall be reviewed with Con Edison for approval.

1.1 APPLICATION

This instruction applies to all Consolidated Edison Company of New York, Inc. (CECONY) organizations and contractors, and outside “third party” organization with oversight responsibility for municipal public improvement contractors and non-municipal contractors, commencing or engaging in underground construction activities associated with excavations, foundations, and demolitions within the vicinity of CECONY’s existing underground transmission system.

2.0 DEFINITIONS

2.1 CECONY refers to Consolidated Edison Company of New York, Inc.

2.2 Contractor is the construction firm hired by the Property Owner or Project Manager to perform the construction services.

2.3 Designated Contact is the contact person identified within the Project Manager Company and the Property Owner who has the responsibility to communicate on all of the planned construction works to be carried out safely.

2.4 Encroachment Area is the area where the ground disturbance occurs within 25 feet on land of the centerline of the Assumed Location of the existing electric facilities.

2.5 Assumed Location is the location of underground facilities determined from the subsurface investigations, such as record drawings or utility mark outs on streets.

2.6 Known Location is the Assumed Location that is visually confirmed from hand dug test holes. Both horizontal and vertical locations of underground facilities shall be field verified at, (a) every proposed crossings, (b) every turn in direction, and (c) a minimum of two locations along a straight run of the existing Transmission Electric Facilities. A use of vacuum excavations is an acceptable means of

http://ceng/



SEPTEMBER, 2018

exposing underground facilities.

2.7 Professional Engineer is the engineer, currently licensed in New York State, hired by the Property Owner or Contractor to perform the engineering/design services.

2.8 Property Owner is the entity that has legal jurisdiction or ownership of the work area or new facility being installed.

2.9 Tolerance Zone is the area in which soil must be removed by non-mechanical means, such as hand excavations methods, to expose subsurface utilities in absence of test pits. It is 2-ft clear distance on both sides of the Assumed Locations and the width of the existing Transmission Electric Facilities.

2.10 Trained Personnel refer to someone who is capable of identifying existing and predictable hazards in the surroundings or working conditions, has authorization to take prompt corrective measures to eliminate the hazards, and is trained and experienced in utility installation and inspection.

2.11 Transmission Electric Facilities refer to underground transmission feeders 69kV and higher and associated circulation piping.

2.12 Wingback is the required longitudinal distance of a pipe to be exposed by excavation in order to achieve the desired relocated position.

3.0 INSTRUCTIONS

3.1 GENERAL INSTRUCTIONS

3.1.1 Follow the requirements outlined in the State of New York Department of Public Service NYCRR 16 Part 753, “Protection of Underground Facilities”.

3.1.2 Perform subsurface investigations and mark-outs prior to planning and performing any work in the Encroachment Area of the underground Transmission Electric Facilities.

3.1.3 Mark-outs of the Assumed Locations of the underground facilities must be refreshed periodically, by the Contractor, to ensure underground facilities locations are always clearly identified over the entire project duration. If at any time the underground facilities marks become illegible, work must be stopped until the locations can be re-identified.

3.1.4 Contractor shall provide proper support of all exposed Transmission Electric Facilities during excavation activities.

3.1.4.1 A work plan, including pipe support design and calculations, shall be submitted to CECONY Engineering for approval, at least two weeks prior to performing any work in the Encroachment Area of the electric facilities. Refer to section 3.4 for pipe support design criteria.

3.1.4.2 For management of excavated soils, refer to section 3.5, “Backfill”.

http://ceng/



SEPTEMBER, 2018

Page 5 of 13


3.1.4.3 CECONY Transmission Operation shall review the work plan on an as-needed basis and shall inspect the work area for pipe support, moving process and coating conditions prior to backfill.

3.1.4.4 The approved work plan shall be obtained by the Contractor prior to commencement of any work.

3.1.5 In absence of test pits, excavation within the Tolerance Zone shall be performed by hand only. Saw-cutting pavements within the Tolerance Zone is allowed with blade depths less than the confirmed asphalt pavement thickness.

3.1.6 For Known Locations, a zone of protection shall be established by shielding the exposed facilities from damage that could result from falling debris, i.e. rocks, concrete, compacted soil, etc. Machine excavation or additional saw-cutting of pavements may then be allowed as directed by CECONY Engineering or CECONY Field Representative.

3.1.7 Maintain clearances and separation distances to the existing Transmission Electric Facilities to the maximum extent possible at all times. Refer to section 3.2 for clearance and separation distance requirements.

3.1.8 Only Trained Personnel should work in the vicinity of exposed underground Transmission Electric Facilities.

3.2 CLEARANCES AND SEPARATION DISTANCE

3.2.1 Existing Transmission Electric Facilities within the Tolerance Zone must be protected in place. In general, a minimum of 3 feet of cover over the electric facilities shall be maintained. When less than 2 feet of cover is authorized because of special conditions, suitable guards shall be placed over pipes as described in CE-TS-3352. Clear distance between the guard and the pipe shall be a minimum of 6 inches. Contractor may be allowed to move the existing Transmission Electric Facilities by following the requirements described in section 3.2.2 and 3.4.4, or the new facilities must be relocated.

3.2.2 Maintain both the following minimum required vertical clearances and horizontal separation distances between existing Transmission Electric Facilities and the new subsurface facilities:

Field Guide for Working around Electric Transmission Lines

Last Review Aug 2011. Presented at Dielectric Leak Prevention Committee April 2009. Document origination: June 13, 2006.

FEEDER TYPES

HIGH PRESSURE FLUID FILLED (HPFF) FEEDERS

HPFF feeder pipes (“Oil‐o‐static” a trade name) are installed with anywhere from one to eight pipes and may include oil return line(s), and may have cables and dielectric fluid inside. See Figure 1.

Sometimes oil return lines are not located in the same trench or on the same street as the conductors. Refer to the appropriate maps and plates for their exact location. When found in the same trench they are usually located above and offset from the feeder pipes but interference with other utilities may have required them to be installed in between or on the side of the feeder pipes.

SOLID DIELECTRIC (SD) FEEDERS

SD feeders are a newer type of feeder and do not have dielectric fluid in them or oil return lines. SD feeders usually are housed fiber‐reinforced Epoxy (FRE) with concrete around the duct bank, but may also be housed in pipe or concrete duct. See Figure 2 & 3. SD feeders may also be direct buried, especially near/within substations.

GAS FILLED FEEDERS

Some transmission feeders consist of pipes that are filled with nitrogen gas; they are called gas‐filled feeders. Their pipes are similar in construction as the HPFF feeders.

LOW PRESSURE AND MEDIUM PRESSURE

There are low pressure and medium pressure transmission feeders as well which may be installed in ducts, or in some cases, may be direct buried. With these systems, the cable is impregnated with oil as well.

GENERAL INFORMATION

Transmission feeder cables exists at voltages of 69KV, 138KV OR 345KV (“Feeders”). Information on transmission feeders can be found on a Composite maps (by borough/county) or individual feeder maps, conduit plates, and sub‐surface drawings (“10 scales”). Most newly installed HPFF pipes and SD feeders have communication control lines associated with them; the majority of the feeders do not. Detail drawings of Bridge crossing are available through the Public Improvement Engineering Group. Some transmission feeders were installed directly in the concrete on bridge crossings without steel protection plates over them, so caution must be taken working on bridges. The backfill used around electric transmission lines is typically sand (either Type 3/8 or thermal sand).

Coatings on feeder pipes and oil return lines may be coal tar and should always be assumed to contain PCBs and ACM unless tested otherwise.

At some locations, the feeder pipes or duct bank can be installed through a sleeve to pass around or under adjacent facilities. The sleeve will be larger than the pipe running through it. Generally, this sleeve will be bare steel and will be in line with the Code 753 markings.

Transmission manholes almost always have dual openings (i.e. two manhole covers). Transmission manholes also almost always have “gas valve box covers” associated with the manhole, which contain cathodic protection test stations. See Figure 4.

If oil or fluid is in the soil or if the pipe is leaking, notify #9, your supervisor and EH&S immediately (follow GEI 2.01 Spill Reporting). Utilize spill kits as required and once the spill has been properly reported, call Transmission Operations (718) 204‐4488 or 4489 to inspect and repair the leak.

Field Guide for Working around Electric Transmission Lines

Last Review Aug 2011. Presented at Dielectric Leak Prevention Committee April 2009. Document origination: June 13, 2006.

BEFORE EXCAVATING Refer to the most current version of the M&S, Conduit, and C&DO plates as well as the Composite Feeder Maps. The feeder maps are available from Transmission Engineering (212‐460‐2914 or 212‐460‐4189).

Ensure that Code 753 markings have been made. Note – the Transmission Lines will be marked “Oil‐O”, “HPP”, “Trans‐FRE”, or “Trans‐STL.” Renew markings as required throughout duration of excavation activities.

If marks are not accurate or missing, contract the area FPG CCI or PI Operating Supervisor (Staten Island): Manhattan: 917‐939‐7912 Bronx: 347‐234‐0125 Brooklyn: 646‐584‐7333 Queens: 917‐559‐3593 Westchester: 347‐672‐8180 Staten Island: 646‐879‐2729

Hold a field meeting with the excavator before work begins. Supervisors/Mechanics/CR/Inspector must review project limits, methods and procedures to support, protect and maintain Con Edison facilities.

Ensure that the most current facility plates and maps are on site.

SAW CUTTING AND MACHINE USE

NO SAW CUTTING of the pavement is permitted directly crossing over feeders or oil return lines that have been identified in the work area, regardless of whether facility is noted shallow cover or not.

Except for removal of asphalt and concrete base, there shall be no mechanical excavation within the tolerance zone of feeders until the location of the facility and any associated piping has been found. HAND DIG ONLY.

TEST PITS

Hand excavated test pits shall be performed to verify the markouts and location of all critical facilities within the work zone as per Code 753 requirements. In addition, critical facilities within 5’ of a work zone, that crosses and run parallel to the work zone, shall be located before beginning any intended excavation with hand excavated test pits. Test pitting shall also be performed as required, to verify the location of critical facilities for extended trenches and excavations. If test pits are to be used to confirm the exact location of the feeders and associated piping and comply with standard excavating requirements by hand and machine.

FEEDER PIPE INSPECTION

If the feeder pipes are exposed, NOTIFY CORROSION OPERATIONS TO INSPECT THE PIPES. If the coating needs repair or removal, the Corrosion Group will notify Underground Transmission to arrange for Company forces or a contractor to do this work. If for some reason Gas Corrosion cannot respond, notify Transmission Operations directly and they will send someone to do the inspection.

CORROSION OPERATIONS PHONE NUMBERS: 718‐579‐1498 or 718‐579‐1216. Inform them of the Feeder number and location.UNDERGROUND TRANSMISSION PHONE NUMBERS: 718‐204‐4489 or 718‐204‐4488. 24‐hr phone number (718)393‐8999

RESTORATION

When pipes pass within 2’ of a water main/service, a Con Edison approved ½” thick rubber sheet (class & stock #059‐5306) shall be installed between the pipe(s) and the water main/service. There shall be an overlap of 6” between sheets if more than one sheet is required. The rubber sheet(s) shall overhang the water main/service by 18”. The rubber sheet should never be wrapped around the feeder pipe. All backfill around transmission feeder pipes and oil lines MUST conform to company specifications. Refer to Specification EO‐1173‐5 “Specification for Controlled Backfill for HP Cable Pipe Installations” for requirements. For additional information on restoration, please refer to CE‐TS‐3352 (“General Specification for installation of High Pressure Pipe for 69KV, 138KV and 345KV Cable Systems, Section 1 – General Requirements”), which can be found on the Central Engineering Website (http://ceng/ceng).
