1. SCOPE
This specification covers the design, materials, welding, inspection, protective coatings,
drawings and delivery of steel transmission single pole structures. The proposal
submitted by the manufacturer shall include field bolts, locknuts, vangs, attachment
provisions for arms and/or insulators, anchor bolts, base plates, and other necessary
items to make a complete structure. .lca files are available upon request. Manufacturer
shall optimize pole designs based on provided loads.
2. DEFINITIONS:
Cambering - the fabricating of a slight convex curve in a pole or crossarm
D/t - the ratio of the diameter of a tubular pole to the steel plate thickness
Engineer - a registered or licensed person, who may be a staff employee or an outside
consultant, and who provides engineering services. Engineer also includes duly
authorized assistants and representatives of the licensed person.
Ground Line - a designated location on the pole where the surface of the ground will be
after installation of a direct embedded pole
Load factors (LF) - a multiplier which is applied to each of the vertical, transverse and
longitudinal structure loads to obtain an ultimate load

structure when the structure deflects from its unloaded position
Point of Fixity - location on the pole at ground line or below ground line where the
maximum moment occurs
Pole twist - Spiral rotation of a pole section relative to the pole end. It is caused by the
residual stress in the steel as received from the mill, the clamping force holding the tube
shells together and the heat applied during the seam welding process.
Raking - the practice of installing a straight pole out of plumb, or at an inclined angle
w/t - ratio of the width of the pole (flat-to-flat) to the plate thickness
Ultimate load - the maximum design load which includes the appropriate load factor
specified

5. GENERAL REQUIREMENTS
The design, fabrication, allowable stresses, processes, tolerances, and inspection shall
conform to the ASCE Standard, Design of Steel Transmission Pole Structures (Manual
72), latest edition, with the following additions and/or exceptions:
a. Design
(1) Pole designs shall be prepared from the attached Pole Replacement Schedule A
and configuration drawings (Attachment B of this Specification). Pole designs
shall be 12-sided galvanized steel. The H-frame structure cross arm shall be 8-
sided galvanized steel. The H-frame structure mounting strap shall be galvanized
steel.
(2) Wind pressures shown in the loading criteria shall be multiplied by the
appropriate shape factor applied to the poles. Pressures in psf shall be
computed as follows:

p = W x Cd
Where p = pressure on projected area of the pole normal to wind, W =
wind pressure, and Cd = shape (or drag) factor.
Shape factors for computing the wind on poles are:
(3) The maximum design unit stress shall be the minimum yield strength as
stated in applicable ASTM specifications for the particular application and
types of loads, including load factors.
(4) Poles shall be designed with a maximum of two joints. Field welding shall
not be allowed as part of the design of a new pole. The shaft joints to be
made in the field shall be slip joints or bolted flange joints. Slip joint length
shall be at least 1-1/2 times the largest inside diameter of the female section.
Bolted flange joints shall be used for medium angle and heavy angle guyed
structures and cross-braced H-Frames.
Manufacturer shall verify slip joint fit before shipment. Joints should not
interfere with joints, step nuts, ladder clips, or jacking nuts.
Sufficient jacking lugs and permanent orientation marks shall be provided at all
slip joints to ensure proper alignment and complete overlap of the joint.
(5) The ultimate load in guys shall not exceed 65 percent of the rated
breaking strength of the guy.
(6) Design of anchor bolts shall be in accordance with the ACI-318-1983
Edition, Building Code Requirements for Reinforced Concrete, assuming a
concrete strength as specified by the owner.
When anchor bolts are specified, they shall have the top 2 feet galvanized.
Anchor bolts shall be threaded at the top end a distance equal to the baseplate
thickness plus the thickness of two anchor bolt nuts plus 2-1/2". Each anchor
bolt shall include two heavy hex nuts.
Welding on anchor bolts will only be allowed in the bottom 12 inches. Only
one length of anchor bolt shall be used on each pole. Anchor bolts/clusters
shall be plainly marked to indicate the structure type, structure number,
orientation, and top of concrete. Anchor bolts shall be designed to be shipped
as a rigid cage with top and bottom plates holding the anchor bolts in place.
The anchor bolt thread shall be protected during shipping. The anchor bolts
shall be welded to the holding plate in the bottom of the cage. The top template
shall be designed to be removable and to support the assembled cage during
lifting and setting operations without detrimental deformations. Bolt clusters

shall be designed to be rigid enough to withstand the normal jolts of shipping,
handling and installation with no displacement of bolts from the proper
positions within the cluster.
The removable template at the top shall be marked to show the centerline for
tangent structures and the angle bisector for angle structures. Matching
marks are to be on the base plate of the structure so proper alignment can be
made.
(7) Minimum plate thickness for all pole components shall be 3/16 inch.
(8) Structures which are to be direct embedded shall have bearing plates and
ground sleeves. Bearing plates shall have a diameter not more than 2 inches
greater than the maximum pole diameter.
Galvanized poles shall have a drain hole at the bottom. The drain hole shall not
be more than 20% of the bottom plate surface area.
Direct embedded and vibratory caisson steel poles shall have ground sleeves.
Ground sleeves shall have a minimum length of 4 feet centered at ground line.
The ground sleeve shall have a minimum thickness of 3/16 inch and shall
be centered at the ground line. A seal weld shall be provided around the
ground sleeve. The ground sleeve shall not be considered in strength
calculations.

The maximum difference in tapers between two pole sections measured
by the diameters shall be .20 inch/ft. for poles with variable taper.
(10) Poles with elliptical cross sections shall have a minor axis dimension equal to
at least 75 percent of the major axis dimension.
(11) All unguyed angle poles or unguyed tangent deadends shall be precambered to
remain plumb when the calculated deflection at the top of the pole exceeds 1.5
percent of the pole height under an initial conductor tension loading of 60 degreesF,
no wind, and no load factors. Pole height shall be the height of the pole from
the top of the baseplate, or designated ground line, to the top. Tangent poles
with unbalanced vertical loadings shall be precambered for the previously
stated conditions.
(12) Arms shall be designed so the end of the arm is at the specified height under
a loading of initial conductor tension, 60 degreesF, no wind, and no load factors.
Arms shall not deflect vertically more than 12 inches at the end of the arm
under heavy ice conditions (without any load factors applied).
Arms shall be upswept or straight, tapered, steel tubular members, of any cross-
sectional type, which meet the dimensions shown on the attached drawings.
Arm end plate connection details for hardware attachment shall be typical of
those shown on the attached drawings. The arms shall be hermetically sealed
when a painted finish is specified. Galvanized arms shall have drain holes
where appropriate.

(13) Lifting lugs are optional. The manufacturer shall supply all instructions for
handling and erection of poles and arms.
(14) In the design of connections for vangs, brackets, or stiffeners attached to the
pole shaft, care shall be taken to distribute the loads sufficiently to protect the
wall of the pole from local buckling.
(15) Thru-vang shall penetrate both sides of the pole with attachment holes on
both sides.
(16) Each pole shall be permanently marked on the pole shaft 60 inches above
ground line and on the bottom of baseplate or bearing plate with the
following identifying information: manufacturer's identification, structure
type, height, structure number, ultimate groundline moment, owner name, and
