STEEL POLES FABRICATION

PS.1 SCOPE

This Specification covers the design, shop fabrication, delivery, surface preparation, galvanizing and related

items necessary to complete the steel poles as indicated on the Drawings and as specified herein. It is the

intent of this Specification to have the poles designed, fabricated and delivered in accordance with the most

advanced and modern technical and commercial practice. Poles furnished shall be complete, ready for use,

and suitable in all respects for the service indicated, despite omission of specific reference to any minor

component part.

PS.2 GENERAL

A. Work to be provided by the Contractor under this Specification shall include the following:

1. Steel poles designed, fabricated and finished as designated herein.

2. Schedules, Drawings, manufacturing and quality procedures, and other information and documents

specified herein.

3. Delivery of poles to job site.

B. The following work will be provided by others:

1. Foundation design and placement.

2. Unloading of poles and anchor bolts at job site.

3. Erection of poles.

C. Codes and Standards

1. Work provided under this Specification shall be in strict conformance with the latest edition and

latest addenda thereto, as of the time work is performed, of the applicable codes, standards,

regulation procedures and tests of the organizations listed in the paragraphs below.

2. Design detailing and fabrication of the poles shall conform to the requirements of the following:

a. American Society of Civil Engineers (ASCE), Standard 48-11, Design of Steel Transmission

Pole Structures.

b. American Institute of Steel Construction (AISC), Specification for the Design, Fabrication,

and Erection of Structural Steel for Buildings, ASD version.

SELF-SUPPORTED STEEL STRUCTURES PS-24 REV 9/15

ESC ENGINEERING, INC.

PS.3 DESIGN AND DETAILS

A. The structural analysis, design, materials, fabrication, inspection procedures, shipping, and

assembly shall conform to the general recommendations of the ASCE Manual No. 72 with

additions and/or exceptions as detailed in this Specification. Fabricator's practices which

differ shall be clearly itemized and submitted with the Proposal for the Engineer's approval.

B. Pole designs shall be prepared from the attached configuration drawings and design loads.

The structures shall be capable of withstanding all specified load cases including secondary

stresses due to specified foundation rotation, and disregarding the possible restraining effect

of conductor or shield wires. The structures shall withstand the loads without failure or

permanent distortion.

C. Regular 12 or 8 sided polygonal sections shall be used. Minimum plate thickness for all pole

components above the groundline shall be 3/16".

D. All pole dimensions shown are from underside of base plate or groundline to wire attachment

points.

E. Dead load of pole shall be included in the analysis along with the following overload factors:

NESC Heavy 1.5

Extreme Wind 1.1

Heavy Ice 1.0

Extra Heavy Snow 1.0

Normal (Camber/Rake) 1.0

F. Maximum foundation rotation under full design loads with overload factors shall be 1°.

Secondary stresses resulting from the foundation rotation shall be included in the design

calculations for all load cases except Normal.

G. Poles and arms shall be designed and cambered so that poles are plumb and arm end points

are at the specified positions under the designated camber (Normal) loadings. Cambering is

not required for less than 6" computed top deflection; poles with less than 6" deflection may

be raked by the line contractor during installation.

H. Welded wire take-off vangs shall be designed by the fabricator. The plates shown on the

Engineer's drawings shall be considered as minimum thicknesses. 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.

I. Poles shall have a nearly uniform taper throughout their entire lengths. The maximum

difference in tapers between two pole sections measured by the diameters shall be .20"/ft. for

poles with variable taper. Final appearance is important and limiting dimensions shall be

selected to avoid both the "tipi" and "smokestack" look.

J. Poles shall be designed with a minimum number of slip joints. No field welding shall be

allowed. Bolted flange joints shall be used for two-pole structures. Slip joint length shall be at

least 1-1/2 times the largest inside diameter of the female joint section. Jacking lugs and

permanent match marks shall be provided at all slip joints sufficient to insure proper

alignment and complete overlap of the joint. Erection drawing shall clearly show required

ESC ENGINEERING, INC. SELF-SUPPORTED STEEL STRUCTURES PS-25 P

minimum slip joint jacking forces.

K. The allowable shear stress for fillet welds shall be 50% of the tensile strength of the weld metal,

but not to exceed the corresponding stress for the base metal.

L. Structures which are to be direct embedded shall have bearing plates and ground sleeves. Bearing

plates shall be a minimum of 3/8" thick unless specified otherwise on drawings. Bearing plates

which are not stiffened shall have a diameter not more than 2" greater than the maximum pole

diameter. Ground sleeves shall have a minimum thickness of 3/16". Galvanized poles shall have a
