The basic water-cement ratio shall be maintained. 4. Forms, reinforcing and subgrade surfaces shall be wetted just before concrete is placed. Wetting down of areas around the work is recommended. 5. The temperature of the concrete when placed shall not exceed 90°F. 6. In extremely hot (90°F and above) and windy weather, sunshades, windbreakers, fog sprays, or a combination of such items shall be used during finishing operations. These provisions shall also be implemented if more than 30 minutes elapses between pours. 7. When weather conditions require concrete to be placed with a temperature greater than 90°F, the Contractor shall submit to the Owner’s Representative a concrete mix design which accommodates high temperature placement. This high temperature concrete may include plasticizers and retarding admixtures to meet the design specification. The Owner’s Representative shall approve any changes in the mix design prior to use. 3.12 COLD WEATHER INSTALLATION A. All concrete work done when the ambient air temperature is 40°F (or forecasted to drop below this temperature within twenty-four (24) hours after concrete placement) shall be in conformance with ACI 306 “Recommended Practice for Cold Weather Concreting” and the following: 1. Mixing water shall be kept well above freezing temperature. 2. Maintain concrete temperature above forty (40) degrees F for at least seventy-two (72) hours after placement. If water cured, protect against freezing temperatures for the duration of the curing period. 3. Concrete forms and reinforcing steel may need to be insulated in order to maintain a local ambient temperature above forty (40) degrees F. Exposed concrete surfaces may also need to be insulated after concrete placement to maintain a surface temperature above forty (40) degrees F. 3.13 TESTING AND LOGS A. The Owner shall contract with a third-party testing company to make compressive test specimens, with each set consisting of five (5) compressive test cylinders made and cured in accordance with ASTM C31 and C172, current edition. B. For drilled pier foundations, one set of compressive test specimens shall be made for each twenty-five (25) cubic yards of concrete placed or at least one set of cylinders made at each foundation, whichever is greater. C. For direct embedded foundations, one set of compressive test specimens shall be made for each twenty-five (25) cubic yards of concrete placed. DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 37 D. Testing of the cylinders shall be handled by the testing company through a qualified testing laboratory, and the cost of testing shall be borne by the Owner. One (1) sample shall be tested at seven (7) days, and three (3) at twenty-eight (28) days. One cylinder shall be held for additional testing in the event of a low break. E. In any case where the strength of the test cylinders for any portion of the work falls below the requirements specified herein, the Owner’s Representative may require the Contractor to secure test specimens of the hardened concrete represented by these cylinders. Specimens shall be secured and tested in accordance with ASTM Designation C42, current edition. If the specimen test further substantiates that the concrete represented by the cylinders and specimens is below the strength requirement specified herein, the Owner’s Representative may order such concrete removed and replaced at the expense of the Contractor. F. The third-party testing company shall also perform tests prior to concrete placement to determine the temperature (ASTM C1064), slump (ASTM C143) and air entrainment (ASTM C231) in accordance with the referenced ASTM designation, current editions.

All work shall be done in a neat and workmanlike manner. Special care shall be taken to ensure that all arms, crossarms, braces, fittings, hardware, and other fixed metalwork are installed in their correct positions. Structures shall be placed accurately and in a correct position of alignment and grade. C. The steel poles shall be handled such that damage to the finish is avoided. D. Every tubular steel structure installation shall have provisions for the installation, testing and preparation of reports for transmission structure grounding, as shown on the Drawings. E. The Owner’s Representative shall inspect each structure and complete the inspection report (sample form on the following pages). All deficiencies noted on these forms shall be corrected by the Contractor prior to acceptance of the line by the Owner. PART 2 - PRODUCTS (NOT APPLICABLE) PART 3 - EXECUTION 3.1 DIRECT EMBEDDED POLE EXCAVATION AND BACKFILL A. Contractor shall have full responsibility for reviewing and checking all such information and data, for locating all Underground Facilities, for coordination of the work with the owners of such Underground Facilities during construction, for the safety and protection thereof and repairing any damage thereto; the cost of all of which will be considered as having been included in the Contract Price. B. Pole holes shall be excavated with straight sides twelve (12) inches larger in diameter than the bearing plate of the pole to allow room for placing the pole into the hole. C. Frozen earth, wood, leaves, decaying matter, or any material subject to decay shall not be used in backfilling. If any water is present in the hole, the water shall be removed from the hole by the Contractor before the backfill is placed. DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 39 D. Rock and other excess excavated material remaining from pole holes located on cultivated land and other unsuitable places shall be removed and disposed of by the Contractor. E. Holes for embedded steel poles shall be drilled according to the depth shown on the Drawings. See standard embedded foundation detail TM-107 for typical concrete backfill placement details. F. For all tangent steel poles, the top one (1) foot shall be drilled twenty four (24) inches greater than the pole’s bearing plate diameter and the remaining depth of the holes will be bored a minimum diameter of twelve (12) inches greater than the pole’s bearing plate diameter. G. A 12” thick preformed concrete plug shall be placed in the bottom of the hole to meet the requirements for concrete at the bottom of the pole as shown on the TM-107 drawing. The plug can be poured early and while it is still green the pole may be set and the remaining concrete poured. The plug may also be poured early and allowed to cure before being placed into the hole. If this is done, the Contractor shall coat the entire surface of the plug with a concrete bonding agent to ensure complete bonding of the wet concrete to the plug. H. Pole backfilling material for tangent steel poles shall be concrete per Section 22040, Concrete Foundations, of this specification. I. The poles are to be set in the hole taking care not to allow the poles to rub on the side of the holes. J. If the concrete in the bottom of the hole becomes contaminated with dirt, the pole will have to be removed and the dirt cleaned from the concrete plug before continuing. A small amount of dust contamination is unavoidable and a short spray of water prior to concrete placement will be sufficient to clean the concrete. K. The poles shall be centered in their holes and/or brackets and plumbed with a transit on the longitudinal and transverse axis. The transit on the transverse axis shall be used to check cant. L. Structures shall be supported with sufficient means to resist the lateral loads on the poles through any inclement weather. The temporary support(s) shall be left in place from 12 hours to 24 hours, depending on wind and weather conditions. The Owner’s Representative will have final authority as to when the support system can be removed. M. Once the structures are plumb and the support is installed, the concrete may be placed. The pole hole shall then be filled with concrete, vibrating from the bottom to the top. The structures shall be watched for movement through the transits throughout the pour. If movement is perceived, the pour shall be stopped and the structure shall be replumbed and/or re-canted before the pour is continued. N. The concrete backfill above grade shall be sloped according to the TM-107 drawing. DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 40 O.

All structures shall be constructed in a workmanlike manner and in accordance with the details on the Drawings. Some of the Drawings may be typical only, and the Contractor shall not be entitled to any additional allowance for minor modifications which may be required. Poles shall not be left unset in holes for more than thirty (30) days. B. For wood structures, not more than one (1) class of pole may be used for any structure, nor may a combination of butt treated poles and full length treated poles be used for any structure, without permission of the Owner’s Representative. C. Where raking is not required, poles shall be aligned as follows: The center of the pole top shall be in vertical alignment with the center of the pole at the ground line when viewed from any direction. Vertical misalignment shall be held within a tolerance of four inches (4") provided that no pole is misaligned in a direction opposing that of another pole in the same structure. However, in any series of structures repetitive misalignment of poles shall be considered poor workmanship and shall be corrected. D. Angle structure poles shall be raked against the conductor strain such that the pole deflects not more than one inch (1") for each ten feet (10') of pole length above ground, after all conductors are installed at the required tension. E. All tangent poles shall be set in alignment with one another and plumbed. These poles shall remain plumb after the conductors are strung. At angle structures where suspension insulators are used, the poles shall be offset on the bisector of the angle so that the conductors shall align directly with the conductors of the tangent structures in both directions. F. Where existing tangent poles are visibly out of plumb and/or as indicated in these specifications, the pole will be re-plumbed. The contractor will submit means and methods to Owners Representative for approval prior to work. Backfill per these specifications. G. Poles shall be set within the following tolerances: 1. Single pole structures -- Plus or minus four inches (+4") parallel to and perpendicular to the conductors. 2. Multi pole structures -- Plus or minus four inches (+4") parallel to the conductor. Perpendicular to the conductors the poles shall be set plus two inches (+2") and minus one inch (1") between adjacent poles. DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 41 3.3 STEEL POLES A.

The structural nuts shall be locked into place with split type lockwashers and tightened to recommended torque value per bolt diameter and material. D. Beveled washers shall be used on sloping or beveled surfaces where required to provide a proper fit. E. Only wrenches approved by the Owner’s Representative shall be used on the work, and the use of any wrench which may deform the nut shall not be permitted. F. All structural metals shall be handled with care to avoid bending or damaging. Pieces bent in handling may be used only if they are straightened in accordance with procedures set forth by the Manufacturer and approved by the Owner’s Representative. G. All structures shall be assembled, aligned and all bolts tightened and/or torqued as required by AISC code of Standard Practice, current edition. After final tightening and before any attachment is made to the structures, the alignment shall be checked. H. Field welds required for steel structure adjustments or miscellaneous additions shall not be made unless authorized by the Owner’s Representative. All welding shall be performed by a welder qualified per AWS, and as required by the pole manufacturer. I. All structures shall be installed in a workmanlike manner. All poles except for those that are cambered or raked shall be set in alignment with one another and plumb. The center of the pole top shall be in vertical alignment with the center of the pole at ground line when viewed from any direction.

The structures are to be assembled on the ground and erected as a complete unit. The sections of the pole should be aligned on the ground and supported, typically with wood blocks, in such a manner that they will readily fit together. Care should be taken to prevent dirt, stones, etc. from getting trapped between the mating surfaces. B. As an alternate, structures may be assembled in the air. The Contractor shall be responsible for any damage caused by dropping one pole section onto another. 3.5 SLIP JOINTS A. All slip joint structures shall be jacked together according to the Manufacturer’s Instructions. B. Use of a hydraulic jacking device is available for rent or purchase from the Manufacturer. C. To facilitate the assembly, mating surfaces may be lubricated. Oil is not acceptable to be used as lubricant. Care should be taken not to use a lubricant that will later leak from the joint and stain the pole. Soapy water has been used successfully for this purpose. D. Jacking forces should be applied until the joint is tight with no more than small gaps visible. Forces in excess of the maximum force shown on the erection drawing should not be applied. The Drawing also shows the minimum force which should be applied to assure good joint tightness and the correct lap length. E. A final check should be made to ensure that the specified minimum overlap has been achieved. Anywhere between minimum and maximum splice is considered an acceptable joint, provided the joint is tight. 3.6 ERECTION A. Prior to lifting the structure, any slipover joint below the crane attachment point should be secured to prevent any possibility of separation during lifting. B. The structure must be attached to the crane: 1. above the center of gravity of the entire assembly including the weight of all equipment mounted on the structure before erection. 2. to the main pole member(s) or, if to the arms, the attachment(s) must be close to the pole(s). 3. as high as possible since higher attachment will result in more vertical alignment of the assembly while suspended above the foundation. C. Care should be taken to operate the crane very smoothly as jerking will cause impact loads which could damage some portion of the structure. D. Structures with baseplate and anchor bolts shall be set with the baseplate level to within 0.1 inches. DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 44 E. Structures shall not be erected on concrete piers until fourteen (14) days after the concrete has been poured and 3000 psi concrete strength has been achieved, and with approval of the Owner’s Representative. F. Wire shall not be strung on the structures until twenty-eight (28) days and/or 4000 psi concrete strength has been achieved, and with approval of the Owner’s Representative. 3.7 BOLTED JOINTS A. Multiple-bolt, moment connections (e.g. arm-to-pole connections, flange connections): Bolts should be tightened in accordance with the latest edition of AISC, and in accordance with Manufacturer’s recommendations. B. Single-bolt, pinned connections (e.g. swing brackets, cross-bracing, pinned crossarms): Bolts should be tightened until the bolt head and nut are snug against the outer plates and the nut locking device is fully engaged. All plates do not need to be in contact. C. Cantilever arms: Before tightening the arm attachment bolts, the arm should be rotated toward the base of the structure to remove all play in the connection. While tightening the bolts, care should be taken to ensure that the arms all remain in the same place. 3.8 STRUCTURE GROUNDING A. Equipment for measuring structure footing resistance shall be furnished by the Contractor. Suitable devices for these measurements include any meters designed specifically for performing a three-point fall-of-potential test, such as the Megger DET3TD device. The testing equipment shall be periodically calibrated, with a Certificate of Calibration kept on file with the Contractor. B. Contractor shall measure the ground plate resistance at each structure, per the manufacturer recommendations for the testing equipment referenced above. Initial testing shall be performed prior to the connection of the grounding system to the structure. C. The maximum ground resistance for any structure is 25 ohms. The Contractor shall record ground resistance measurements for each structure location on a Ground Resistance Report (sample form included in the following pages), which shall be submitted to the Owner’s Representative for review and approval. D. As a minimum, the Contractor shall provide and install one ground plate per each embedded pole. The ground resistance shall be measured and recorded and, if the desired resistance is not achieved, the Contractor shall continue to install additional ground rods until the desired ground resistance is achieved.

Contractor shall provide grounding for the protection of personnel. PART 2 - PRODUCTS (NOT APPLICABLE) DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 51 PART 3 - EXECUTION 3.1 HANDLING A. Care shall be exercised to avoid kinking, twisting, or abrading the conductor in any manner. Conductors shall not be trampled on, run over by vehicles, or dragged over sharp rocks. The wire on each reel shall be inspected for cuts, kinks, or other imperfections. Injured portions (or crooked or imperfect splices) in the wire shall be cut out and the wire re-spliced. Bends of less than the minimum bending radius shall not be permitted. To avoid damage to the conductor, the Contractor may be required by the Owner’s Representative to reinforce the reels or rewind the conductor on new reels. Re-reeling of conductor because of reels damaged by the Contractor shall be at the expense of the Contractor. No payment shall be made for any reinforcing of reels. B. Reels of conductor shall be picked up with a spreader bar to prevent crushing of the conductor and/or the reel. C. Braking of the reels shall be positively controlled by means of a mechanically adjustable device and shall be applied in a manner which will avoid damage to the conductor, reel and line structures. 3.2 STRINGING A. Conductors shall be pulled over suitable rollers or stringing sheaves properly mounted on the pole or crossarm to prevent binding while stringing. Stringing sheaves may be hung on insulator strings or traveler slings (chokers) of equal length or attached to the structure arms with suitable hooks or clamps that properly distribute the load on the arm. The stringing sheave shall support the conductor within twelve inches (12") of its permanent elevation when clipped in. B. Any part of the structure subject to abrasion by the pulling line or conductor shall be protected against damage by suitable lagging. The pulling (sock) line shall be connected to the conductor with a swivel connection and a stocking type grip. The open end of the stocking type grip shall be bonded with equipment approved by the Owner’s Representative. Tail wires of the grip shall be taped down so that the grip will run freely in the sheaves and will not damage them. Sheaves damaged by pulling lines shall not be used on the conductor. C. The conductor shall not be permitted to contact any object which may damage it. When tension is used to clear obstructions, the tension shall not be permitted to exceed the sagging tension prescribed for the portion of the line involved. Adequate guards shall be provided where there may be danger of the conductor being run over by vehicles or damaged by other equipment and/or objects. The conductor shall not be left in contact with the ground, plant matter, or any conducting or semi-conducting material longer than three (3) days. D. Unless otherwise specified by the Owner’s Representative or in these Specifications, the conductors shall be strung by the controlled tension stringing method. DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 52 1. Neoprene lined (or approved equal), double bullwheel type tension stringing equipment shall be used to string conductors by the controlled tension method. The equipment shall have a bullwheel diameter and groove sizes that will in no way damage the conductor. It shall be of a type capable of maintaining preset tensions and pulling speeds. Sufficient continuous tension shall be maintained to keep the conductor clear of the ground or obstructions that could damage it or that could be damaged by it. Sheaves shall be designed and used so that the pulling line does not damage them or deposit foreign matter in the liners that may damage the conductor or be deposited on the conductor. 2. The maximum pulling tensions shall not exceed 110% of final sag tension. The cable pullers, tensioners, and pulling machines shall be located as near midspan as possible, but in no case shall the slope of the conductor between the pulling machine and stringing block at the first structure be steeper than four (4) horizontal to one (1) vertical. The length of conductor pulled in one operation shall be limited to that length which can be sagged satisfactorily, as approved by the Owner’s Representative. E. During stringing operations and before sagging, if it becomes necessary to leave the conductor in the stringing blocks for longer than eight (8) hours, the conductor shall be left at reduced tension. The percent of sag, the spans involved, and the time interval shall be noted and this information forwarded to the Owner’s Representative. F. The use of wire reels must be carefully planned to minimize the number of full-tension splices. Every attempt should be made to maximize wire reels and limit the number of partial reels left over at end of the project. G. All wire set-up locations shall be reviewed and approved by the Owner’s Representative prior to wire installation. 3.3 SAGGING A. Prior to sagging, all guys shall be pulled, all angle structures raked, and all deadend structure baseplates shall be level. B. Conductors shall be sagged by the Contractor in accordance with the Stringing Sag Tables furnished. Each conductor shall be sagged individually for the temperature at the time of sagging. All conductors in a sag section shall be treated uniformly with respect to tension and time intervals during stringing and sagging. Sagging operations shall not be carried on when, in the opinion of the Owner’s Representative, wind or other physical conditions prevent satisfactory sagging. C. Contractor shall be responsible for contacting the Owner’s Representative to determine the need for offset clipping. Contractor will give the Owner’s Representative wire setup locations four (4) weeks prior to required time for Owner’s Representative to calculate offset clipping requirements. D. The length of conductor sagged in one (1) operation shall be limited to that length which will permit attainment of the correct sag. Requests for the installation of anchor snubs shall be DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 53 submitted to the Owner’s Representative for approval. Anchor snubs shall not be located so close to the structures that the crossarms will be overloaded. Temporary anchoring of the conductor shall not be permitted on any structures except deadend structures at the normal point of attachment. Conductors shall not be left attached to temporary anchors for more than ten (10) days, unless otherwise approved by the Owner’s Representative. E. Spans used for determining the correct sag shall be, where possible, longer level spans that resemble the ruling span listed on the stringing charts for the section of line being sagged. The sag shall be determined on both sides of angles of more than ten degrees (10°). When sagging a conductor section of more than four (4) spans, the sag shall be determined at or near each end, but not less frequently than at 5,000 foot intervals. In unusual situations, additional determinations may be required. After the conductors have been pulled to the correct tension, as many successive spans as can be observed from the instrument positions shall be examined for uniformity of sag. Determination of the sag shall be by means of return wave method, or by use of a transit or theodolite with targets, all of which to be furnished by the Contractor. Targets shall be positioned after stringing of the conductor. F. It is acceptable to use a dynomometer for sagging operations if verified by use of a transit or theodolite with targets as described above and as approved by the Owner’s Representative. G. The wires must be sagged in accordance with the stringing sag tables provided with the construction drawings. The wires shall be sagged within a tolerance of +3” and -0” of the specified sag. Under no circumstances shall a decrease in the specified sag be allowed. H. The air temperature at the time and place of sagging shall be determined by a certified thermometer placed inside a piece of conductor of the type and size being strung. This assembly shall be suspended a minimum of five feet (5') above the ground in an exposed, sunlit area. The temperature at which the conductor is sagged and the spans in which sags are measured shall be recorded and signed by the Contractor and this information shall be given to the Owner’s Representative. (A sample form is included on the following page) I. Any foreign matter (such as pitch, paint, grease, etc.) on the conductor and fittings shall be removed by non injurious methods before the conductor is final sagged. J. Prior to sagging a new section of conductor, the insulator strings on at least three (3) suspension structures adjacent to the new section shall be clipped in. These insulator strings shall be in a plumb position, plus or minus one inch (+1"), upon completion of the sagging of the new section and during plumb marking. K. All conductors in a sag section shall be sagged, plumb marked (if required), and clipped in during one continuous three (3) day period. 3.4 CLIPPING-IN A. Suspension clamps shall be installed so that the insulator string hangs in a vertical plane through the point of the insulator string attachment to the structure, with the structure properly aligned. Torque wrenches approved by the Owner’s Representative shall be used to tighten the suspension clamps to the torques recommended by the hardware manufacturer. DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 54 B. All conductors in a sag section shall be clipped in as follows: 1. In flat terrain, upon completion of sagging, clipping in shall begin at the second structure from the forward end of the pull and progress back on line, structure by structure, until all structures are clipped in. 3.5 SPLICES AND DEADENDS A. If splicing is approved for this project, it shall be performed in the presence of the Owner’s Representative. Splices shall not be made within fifty feet (50') of a structure, nor shall there be more than one (1) splice per conductor in any span. Splices shall not be installed in crossings over railroads, roads, highways, transmission lines, or rivers. Splice sleeves shall not be installed within one hundred feet (100') of a deadend. Whenever splices are made under tension, come alongs shall not be placed nearer than twenty five feet (25') to the point of the splice or deadend. B. The conductor shall be laid out straight for a distance of fifty feet (50') and straightened before preparation of the ends for splicing or deadending. The portion of the conductor damaged by the grips shall be cut off before the conductor is spliced. The aluminum strands shall be cut back a distance that will leave not more than one eighth inch (1/8") between the ends of the conductor strands and the compressed steel sleeve. Before compressing, the ends of the conductors and the bores of the compression sleeves shall be thoroughly cleaned, and an appropriate amount of oxide inhibiting joint filler compound shall be placed inside of the compression fitting. The lay of strands shall be tightened before the first compression is made. The compression process shall be carefully performed so that the completed assembly is as straight as possible. If, in the opinion of the Owner’s Representative, the completed assembly requires straightening, it shall be straightened on a wood block by the use of a sledge and shaper, wood maul, or hydraulic press. However, if the steel sleeve of a two piece sleeve is bent too much to slip inside the aluminum sleeve, it shall be straightened by constantly applied hydraulic pressure, or it shall be replaced. The steel sleeve shall not be straightened by pounding it with any type of hammer or maul. C. After compression has been completed, all corners, sharp projections, and indentations resulting from compression shall be carefully rounded. All other edges and corners of the fittings that have been damaged shall be carefully rounded to their original radiuses. Nicked or abraded surfaces shall be carefully smoothed. Tape, tape residue, and excess filler paste shall be removed from the fittings and conductor. D. All compression fittings shall be installed in accordance with the procedures recommended by the manufacturer. All compression tools and equipment required for the splicing or deadending of overhead conductors and shield wires shall be furnished by the Contractor. E.

Damage is defined as any deformity on the surface of the conductor which can be detected by eye or by feel. Damage includes but is not limited to nicks, scratches, abrasions, kinks, basketing, popped out strands, and broken strands. B. Depending upon the severity of the damage and the length of the damaged section, repair shall be made by carefully smoothing the conductor with fine sandpaper, covering it with Preformed repair rods, or by cutting and splicing. All options shall be discussed with the Owner’s Representative prior to performing the work. C. Kinked, basketed, or severely damaged sections of conductor shall be cut out. When there is repeated damage in the same span or in consecutive spans, all conductor in these spans shall be replaced. D. When one (1) aluminum strand is broken or nicked deeper than one third (1/3) its diameter, or when a number of strands are reduced in area not exceeding the area of one (1) strand, a Preformed repair rod shall be installed. When more than one (1) strand is broken or the conductor is reduced in area by more than one (1) strand, the damaged section shall be cut out. E. Not more than two (2) splice sleeves for repairing damage shall be applied in any two hundred feet (200') of conductor, except at the direction of the Owner’s Representative. Compression repair splice sleeves shall not be installed within fifteen feet (15') of a suspension structure. A minimum of twenty feet (20') of conductor or shield wire shall be cut off on each side of the damaged section. 3.7 JUMPERS A. Jumpers shall be so proportioned and hung that under normal conditions they will meet the clearance requirements of the National Electrical Safety Code (NESC), current edition. B.

Where unusual conditions cause impaired clearance, the Owner’s Representative shall issue specific instructions. C. Oxide inhibitor compound shall be used on all jumper pad connections. 3.8 CLAMPS AND JOINTS A. All contact areas shall be thoroughly cleaned before installing parallel groove clamps and copper to aluminum joints, whether bolted or compressed. The contact areas and bolt holes shall be coated with oxide inhibitor compound. The contact areas shall be wire brushed through the coating to remove any oxide film. The fittings shall be installed without removing the compound. After the installation of the parallel groove clamps, the grooves at DENTON MUNICIPAL ELECTRIC RFP EXHIBIT 2 – TECHNICAL SPECIFICATIONS REV 0, 10-31-2024 Page 56 the sides and ends of the clamp shall be filled with compound. The compound to be used shall be Burndy "Penatrox A" or its equivalent, as approved by the Owner’s Representative. Bolts shall be brought down hard, but the threads must not be overstressed. 3.9 GROUNDING A. In addition to the grounding provisions of applicable national, state, and local safety codes, the following requirements shall apply: (1) The Contractor shall place electrical grounds at both ends of the line or section of line being worked on under the Contract and also at such intervals along the line as the Owner’s Representative may direct, using ground sets to be furnished by the Contractor; (2) Grounding sets installed at both ends of the line or a section of line shall remain in place until completion of the work by the Contractor. These provisions shall not prevent the Contractor from furnishing and installing as many additional grounds as he deems necessary for the protection of his own workmen against static electricity and accidental contacts with foreign circuits. B. Grounds shall be firmly installed to avoid loose or intermittent connections. All grounds furnished and placed by the Contractor for protection against static electricity shall be of adequate size and shall be clearly visible for inspection. Grounds shall be flagged with a red cloth placed in a conspicuous place on the conductor at the point of grounding.

All material removed from existing facilities shall be done in a neat and workmanlike manner and shall be disposed of as directed by the Owner’s Representative. B. Material to become the property of the Contractor shall be all removed wood poles, down guys, anchors, crossarms, bracing, insulators, nuts, bolts, hardware and miscellaneous conductor fittings. All removal materials shall be removed from the project and disposed of in an appropriate manner by the Contractor. The Owner may elect to salvage any removal materials, as directed by the Owner’s Representative prior to performing removal work. PART 2 - PRODUCTS (NOT APPLICABLE) PART 3 - EXECUTION 3.1 CONDUCTOR AND SHIELD WIRE A. Removal assembly units cover the furnishing of all labor, equipment, and devices for the removal of existing units of construction. Except as noted herein, once the material is removed it shall become the property of the Contractor. B. Fiber optic cable and switches removed shall be returned to the Owner. The fiber optic cable shall be carefully rolled on a reel in reusable condition. C. Conductor shall be placed on reels or coiled and returned to the Owner. D. The Contractor shall inspect all removed transformers for functional and structural damage and paint condition. If no damage is observed, the Contractor shall reinstall the transformers in their new locations as indicated on the plan and profile sheets. If damage to the transformers is visible, the Contractor shall return the transformers to the Owner and shall acquire the appropriate replacement transformers. The Owner reserves the right to substitute or change any transformer during the transfer process. E. The unit removal prices shall include all material and labor required to reinstall in accordance with specifications any conductors temporarily detached. The Contractor will reinstall at his own expenses any other units removed by him for his own convenience. F. The removal units are specified by the prefix I and followed by the assembly unit designation for existing assembly units to be removed, For example, an I-A1 signifies the removal of an A1 assembly unit. G. The following special notes apply to specific conductor or anchor removal units: Page 64 1. Conductors. The conductor removal unit covers the removal of conductor or cable and reeling or coiling it in a workmanlike manner. The Contractor will retain possession of all jumpers, tie wire, armor rods, connectors, and other conductor accessories removed. These items will not be returned to the Owner. a. The removal unit for each size of conductor or cable is shown by the prefix I followed by the conductor or cable type; thus an I-Raven signifies the removal unit for Raven (1/0 AWG, 6/1 ACSR) conductor. 2. Anchors. Only anchor rods are to be removed by the Contractor in anchor removal units. The anchors will be left in the ground; thus an I-TA signifies the removal of any anchor rod. If the rod cannot be unscrewed, the end of the rod will either be cut off or bent down so that the rod will be at least 18 inches below ground. 3.2 POLES A. All poles shall be removed in their entirety and the pole hole(s) backfilled with material that is nearly the same as the native material at the structure site. Backfilled holes shall be compacted and additional fill added if needed so that the grade is slight raised and after settling will be flat. Borrowing of backfill from the right of way shall be at the approval of the Owner and/or the Owner’s Representative. B. All concrete caisson foundations and guy anchors shall be removed to at least 3 feet below grade. The Contractor will be responsible for disposing of all materials from the job site, and furnishing backfill to place in the holes remaining from the caisson removal. C. All steel poles removed shall be handled in a workmanlike manner and delivered to location as indicated by Owner or Owner’s Representative. D. Poles. The same unit designates all poles of the same height, regardless of pole class. Thus an I- 30 signifies the removal of a 30-foot pole of any class. The Contractor is not required under this unit to remove from the pole any ground wire or pole numbering attached to the pole. This unit includes the refilling and tamping of holes in a workmanlike manner unless they are to be reused. This unit requires the complete removal of the pole. E. Pole-top Assemblies. The unit of removal of pole-top assemblies includes, in addition to the removal of the assembly itself, any necessary handling, re-sagging, and retying of conductors in those cases where an existing pole top assembly will be removed and replaced by a new pole-top assembly and where any existing conductor is to be reused. The unit of removal of pole-top assemblies also includes any holding or handling of mainline or tap conductors at tap lines, angles, and dead-ends where such is involved, and reinstalling of such conductor in accordance with the specifications; for example, an I-A5-4 will include the disconnection of the tap conductors, snubbing off the tap line at the nearest practical point and the reconnection and re-sagging of these tap conductors if necessary to the new tap assembly when installed.
