b) Understanding township, range, and section lines


2. Measurements

a) Length ― pacing, 100-ft tape, Rolatape (wheel),      rangefinder, vehicle

b) Turning and bisecting line angles ― 100-ft tape,

pull-finder, hand compass, transit

c) Structure alignment ― range rods, binoculars,



3. Elevation profile and object height

a) Measuring changes in elevation using a hand level

b) Measuring height and elevation using an Abney

level or clinometer

c) Using a transit and level rod for surveying a

complete elevation profile


4. Special techniques

a) Running offset lines around obstacles

b) Busting-in between two points

c) Extra long distance alignment


5. Total station (introduction and overview)

a) Description of equipment and accessories

b) Programming the job and conducting a survey

c) Transfer of field data to AutoCAD

aerial photographs                                  continued

OVERHEAD STRUCTURE DESIGN:  The student will learn to design overhead electrical distribution structures.  Tables and graphs will be provided for the student to lookup design values for immediate application in the field.  He or she will also learn to make basic calculations to determine strength and maximum allowable spans for wind and ice loading, plus total guy load due to tension and wind.

  3. b) Climbing and working space for operating personnel
  4. c) Separate lay and random lay of underground cables in a joint use trench
  5. d) Position of power and communication cables in an underground duct system


  1. Joint use contracts
  2. a) The anatomy of a joint use contract
  3. b) Owner and renter responsibilities
  4. c) Permitting and application procedure

  1. Performing make-ready surveys
  2. a) Establishing attachment positions and measuring clearance
  3. b) Preparing construction specifications and cost estimates

UNIQUE STRUCTURES:  The student will learn to design special structures that require additional strength due to extreme wind load, long spans, and multiple circuits.  This section also includes designing steel pole and unguyed wood pole structures.


  1. Extreme Wind Loading
  2. a) Evaluating pole strength for extreme wind applications
  3. b) Example problems


  1. Double Circuit
  2. a) Configuration options
  3. b) Guying techniques
  4. c) Vertical spacing between circuits
  5. d) Maximum span lengths


  1. Steel poles


  1. Un-guyed line angle poles


Workbooks and manuals will be supplied for the specialized instruction.  Each student will be required to supply a personal copy of the National Electrical Safety Code and RUS Specifications.  Each student should bring a scientific calculator and note taking materials to each seminar.  The students will work class problems both in groups and individually.  These problems will involve both the lookup tables and calculations based on the material contained in the manuals.  The instructors will answer questions and go through the solutions to the problems.  The instructors will also be available to discuss ideas and questions to a reasonable extent after normal class hours.                         


The course of study leads to certification as a qualified staking technician.  The certification will be awarded after the student accomplishes well-defined tasks and demonstrates a working knowledge of the subject material though observation and completion of comprehensive written tests.  The classroom and field training is divided into three phases of four domains each to be taught in three separate four-day seminars).  To achieve certification, the student must attend all three seminars and pass a test for each of the twelve domains.  Students may re-take any test if their first try is unsuccessful.
