3.4 ASSEMBLY
A. 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 7483 – TECHNICAL SPECIFICATIONS
REV 0, 08-22-14
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 rod 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 install one ground rod (two 10-foot sections) driven into
undisturbed soil (outside the pole excavation) with the top of the rod buried 2 feet below
grade. 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. The Contractor shall record the final resistance value along
with the total number of rods installed at each structure.

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 7483 – TECHNICAL SPECIFICATIONS
REV 0, 08-22-14
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 7483 – TECHNICAL SPECIFICATIONS
REV 0, 08-22-14
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 7483 – TECHNICAL SPECIFICATIONS
REV 0, 08-22-14
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. Bolted deadends, when specified, shall have bolts torqued to manufacturer’s specifications
with a torque wrench approved by the Owner’s Representative.

Page 64
G. The following special notes apply to specific conductor or anchor removal units:
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.
Pole-top Assemblies. The unit of removal of pole-top assemblies includes, in addition to the removal
of the assembly itself, any necessary handling, resagging, 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 resagging of
these tap conductors if necessary to the new tap assembly when installed.
