Costs 10) Network service will cost extra for the owner, due to a) Vault and primary-voltage duct bank cost b) Increased fault current levels c) Possible contribution to GPC to receive this premium level of service 11) GPC cannot provide a detailed estimate until the following are provided: a) Electrical riser diagram that includes # and size of mains, voltage, and metering required b) Electrical Panel Schedules allowing GPC to determine demand loads c) Utility/Civil Site Plan indicating the location of other utilities and other possible conflicts

23 SECTION 1 CONDUIT SYSTEMS Material Selection The standard conduit material for the construction of underground conduit systems is PVC, Type DB-120. This conduit is stocked in 5 foot and 10 foot lengths in both 4 inch and 6 inch diameter. The 5 foot lengths are lightweight and easily handled, thus permitting installation in "tight" excavations where trench jacks and foreign utility crossings are encountered. Other conduit materials are a schedule 40 PVC. This conduit is stocked in 10 foot lengths and is used for bridge crossings and tunnel/casing installations. Galvanized steel conduit usage is limited to special installations requiring strength such as pole risers. Its use in underground conduit is not recommended because of the possibility of a cable fault damaging the conduit or welding itself to it. A damaged conduit can result in damaging the newly installed cable or make removal of the failed cable impossible. Plastic spacers are used to support the conduit and are manufactured in specific sizes and separation. The spacers stocked are for 4 inch and 6 inch PVC conduit with a 2 inch separation between ducts. The spacers interlock both horizontally and vertically and are stocked interlocked two wide. Spec. Page 1.11 lists all standard conduit materials for the 4 inch and 6 inch sizes which is presently stocked. Split PVC conduit is used for rebuilding damaged ductlines containing cables. This material uses the tongue and groove method and is available in 10 foot lengths. Smaller diameter conduit can be used for individual services to small customers where additional load should never be required. This material and its accessories are not stocked and must be purchased. Construction Plans Detailed drawings will be prepared by the Underground Network Engineering Section in Atlanta. Prints of these drawings will be furnished to the Company's Underground Network construction crew or to designated contractors who will bid the job. The successful bidder will be responsible for construction of the entire job as shown on these prints. These prints show the proposed conduit systems, manholes and/or transformer vaults required by the Company, as well as existing Company conduit systems, manholes and/or transformer vaults. The prints also show the various foreign utilities existing in the proximity of the proposed construction (i.e., gas, water, sewer, telephone, steam, etc.). This information was obtained from field surveys by the Company and from records kept by the various utilities. Previous experience with these utilities has indicated that their records are in many instances somewhat inaccurate and incomplete. Also, there are few records of the location of service taps. The user of these prints shall therefore be aware PAGE 1.01

24 that while due effort is exercised to assure accuracy, certain discrepancies might be found. The foreman responsible for the job (whether Company or contractor) should note any discrepancies found in the field as well as any minor changes in actual construction on his prints and return them to the Company for posting. Any major construction changes must be approved by the Underground Network Engineering Section in Atlanta. Materials Furnished to Contractor If the conduit system is to be constructed by a contractor, the Company will furnish the following materials: conduit, conduit bends, conduit couplings, conduit plugs, and conduit spacers. The contractor will be responsible for obtaining the material from the Company and keeping up with it once it is in his possession. He will also be responsible for the balance of the materials required for the construction of the conduit system. Excavation The trench required by the conduit shall be carefully excavated at the location and to the depth as shown on the construction drawing(s) furnished by the Underground Network Engineering Section in Atlanta. The width of the excavation shall be such as to allow a minimum of 3 inches for the concrete envelope outside the outside ducts on both sides of the conduit. Since the sides of the excavation are used for the sheathing forms, they should be trimmed smooth to give a uniform vertical surface throughout. For general excavation requirements see Power Delivery Bulletin No. 8-7, Safe Practices for Making Excavations. Conduit Construction All conduit and couplings shall be inspected prior to installation. Any conduit found that is damaged (broken ends or bells, holes, flattened sides) shall not be used in the main conduit run. However, it is permissible to use damaged conduit at locations requiring a short section if the damaged portion can be removed. Plastic base spacers shall be placed across the bottom of the trench at about 5 feet intervals so they form the grade for the first row of ducts. The bottom row of spacers shall provide a space of not less than 3 inches between the bottom of the trench and the outside of the bottom row of ducts. The first row of ducts shall be laid on the base spacers. All conduit shall be fully pushed into the bell of the previous piece installed. It is suggested that all PVC conduit be cemented together. However, if the fit between the conduit end and the bell end is tight, the cementing operation may be omitted. If the fit is tight, the conduit may have to be driven together by placing a block of wood against the last section of conduit and striking it with a hammer. Do not strike the conduit directly with the hammer. All conduit bends and all conduit installed in casings, tunnel liners or bridges must be cemented together to prevent it from coming apart during the concrete encasing, or temperature cycling for conduits installed on bridges. For conduit that is to be cemented together, apply an even coating of cement (C-7660/7662) on the surface of and around the entire conduit equivalent in length to the depth of the bell end. Immediately insert the conduit into the bell end with a slight twisting motion until it bottoms home. Do not twist or turn the conduit after it has bottomed out as this will weaken the bond PAGE 1.02

25 Intermediate plastic spacers shall be placed across the first row of ducts and interlocked with the base spacers. The next row of ducts shall then be placed on the intermediate spacers until the last ducts are installed. Finish up the formation by interlocking an intermediate spacer over the top ducts. In this manner a rigid skeleton PVC conduit structure is progressively built up to the full height of the formation. If an existing damaged conduit line containing cables is to be repaired, it shall be repaired using split plastic conduit using the following procedure: Carefully remove the concrete from the damaged conduit(s) and expose several inches of undamaged conduit on each side. The exposed conduit(s) should be squared off as much as possible. Cut the split conduit to the proper length and snap it in place around the cable. Secure the two halves with the plastic straps furnished. Use a split PVC repair coupling and install one at each end where the split conduit joins the existing conduit. Secure the couplings with nylon straps and wrap the couplings with plastic tape to prevent the entrance of concrete into the conduit. Finish the repair by encasing it in concrete. If the conduit does not contain a cable, it can be repaired with a section of standard PVC conduit. Slope Conduit lines shall be installed with either a single slope which drain from one manhole to the next or with a double slope with drain toward both manholes. The slope of any conduit line shall not be less than 0.25 percent, or a fall of 3 inches in 100 feet. Construction of conduit lines containing valleys shall be avoided. Since such a conduit system cannot drain, time may render this system useless. If construction of a conduit line containing a valley is unavoidable, a ductline drain shall be installed at the lowest point of the conduit system (see Spec. Page 1.29 for details). Concrete Envelope All conduit systems shall be encased in concrete to minimize the possibility of a digin and for mechanical strength during future utility construction projects. The concrete to be used shall be a 2500 psi mixture containing #7 stone (maximum 3/8 inch diameter) per Georgia Power Company Specification NWC-11. The concrete shall be machine mixed to the proper mass consistency capable of flowing down the concrete chute and around all of the ducts. If it is mixed too wet or sloppy it has a tendency to lift and float the entire conduit structure requiring that it be weighted down or anchored against the wall or base of the trench. When pouring concrete over the conduit structure, it shall be poured at a slow rate to insure the flowing of concrete between and under each individual duct to prevent voids. Concrete shall be poured to a height of not less than 3 inches above the outside of the top layer of the conduit structure. This can be determined by using the protruding intermediate spacers as a guide. When dropping concrete from a great height, portable chutes shall be used to break the fall of concrete on the duct and to prevent separating the concrete mixture and damage to the conduit system. If the pouring is stopped, the end of the pour shall be allowed to seek its own slope in order not to produce a vertical break and weaken the structure. Foreign utilities in close proximity to the conduit system shall not be encased in concrete. If necessary, construct a box around the foreign utility or otherwise protect it from encasement PAGE 1.03

26 Backfill If shoring has been installed to the bottom of the trench, it shall be left in place a minimum of 4 hours before it is pulled out. If left in place too long, it will be difficult to remove. An effort must be made to remove all of the shoring installed so as to minimize the amount of wood left in the excavation. Backfilling can be started as soon as the concrete has set enough that it will bear the weight of a man walking on it. The backfilling shall be well tamped and shall consist of dry dirt free from rocks, paving material, wood, rubbish and other foreign material. The trench may also be backfilled with a flowable fill with a consistency of approximately 300 psi. Street Restoration If the original street surface consisted entirely of concrete, the trench excavated for the conduit line shall be finished with a minimum thickness of 10 inches of 3000 psi high early concrete flush with the existing surface. If the original street surface consisted of asphalt, the trench excavated for the conduit line shall be finished with a minimum thickness of 10 inches of 3000 psi high early concrete to be leveled one inch below the existing surface. The remaining one inch shall be filled with asphalt. If the conduit line was installed in a state highway, the street shall be repaired according to State Highway Specifications (see Spec. Page 1.93). If the conduit line was installed in a sidewalk, the sidewalk must be replaced with like kind material. Pole Riser When installing a conduit connection to a pole, a 10 foot section of G.I. conduit shall be temporarily installed on each conduit and properly aligned to the pole before any concrete is poured. The conduit coupling immediately below the sidewalk area must be one for adapting a PVC conduit to a G.I. conduit (see Spec. Page 1.57, item 4B). Abandoning Conduit Conduit lines to be abandoned shall be sealed at both ends with cement. Conduit bends at poles shall be cut level with the surface grade and sealed with cement. Responsibilities The foreman in charge shall be responsible for keeping the excavation free of water and debris and for protecting it against damage by cave-ins, etc. When construction is stopped at the end of the day or during inclement weather, all ducts shall be closed with conduit plugs to prevent the entrance of mud or foreign matter into the ducts. If required, the excavation shall be steel-plated at the end of the day so as to allow the movement of vehicular traffic. The foreman in charge shall also be responsible for exercising all possible precaution for the protection of property belonging to others than the Georgia Power Company against damage and also for providing as much as possible for the unhampered use of such property during the construction and afterward. This applies to such matters PAGE 1.04

27 as the protection of lawns, protection of trees against an undue amount of damage to roots, supporting sidewalks, driveways, foreign utilities, etc., where they might be cracked or broken when undermined, and supporting long runs of pipe crossing the trench against a possible break PAGE 1.05
