Design of Transmission Lines, Structures, and Foundationsinterpro.wisc.edu/RA00065 See upcoming dates
This in-depth course provides you with the latest criteria and practical techniques used in the design of transmission lines, structures, and foundations. You will learn transmission design concepts that use traditional methods and modern software and participate in class design exercises.
Course topics include:
- Single and multiple pole wood and steel structures
- Latticed steel towers
- Conductor design and behavior
- Line assessment and upgrading concepts
- Strength analysis for joint use
- Foundation design
This up-to-date course applies to the design of new transmission lines and the upgrade of existing ones.
Who Should Attend?
- Transmission line design engineers
- Structural engineers
- Consulting engineers
- Design and drafting technicians
- CAD technicians
Experienced individuals and those recently assigned to transmission line projects will benefit from this course.
Note: This course does not include training on the PLS-CADD computer program.
Important: However, several classroom exercises in both transmission line design and foundation design will be computer-based. We recommend you bring your own laptop which must comply with the course laptop requirements. Computer rental is available for a $300 weekly fee. If you prefer to rent a computer, please indicate that choice when enrolling in the course.

Otto J. Lynch
Otto J. Lynch, PE, is the President and CEO of Power Line Systems and an internationally known expert in transmission line design and the PLS-CADD computer program. He has conducted numerous seminars and training sessions in its use and applications. Prior to joining Power Line Systems in 2000, Mr. Lynch was with Black & Veatch for over 12 years doing civil/structural design for substations and transmission lines. He has designed several families of lattice steel transmission towers and has worked on transmission projects ranging from 69kV to 500kV utilizing wood, tapered tubular steel, lattice steel, concrete, and laminated wood structures throughout the world. Mr. Lynch is a pioneer in integrating LiDAR (Light Distance and Ranging) aerial survey data into the PLS-CADD program for transmission line rerating and reconductoring projects. Mr. Lynch is an expert in all the computer programs that will be used throughout the course.
Vicki Schneider, PE, PMP, is Director of Engineering Services for Mortenson Engineering Services, Inc. in Minneapolis, Minnesota. She has over 20 years of structural/foundation engineering experience in projects for electric utilities, fabricators and EPC (engineer-procure-construct) projects. Over the years, she has also worked as a design team member on hospitals, banks, hotels and event centers for above grade and foundation designs. Mrs. Schneider has significant experience as the Engineer of Record on substation and transmission line projects. Her substation structural design and transmission line experience ranges from 34.5kV to 500kV for all aspects of design including, but not limited to, shallow foundations, spread footings, direct embedded poles and drilled piers.

Several classroom exercises in both transmission line design and foundation design will be computer-based. For this purpose, we ask that participants bring their own laptop computers. It is not required but having a laptop will be helpful in participating in our short computer-based exercises.
Computer rental is available for a $300 weekly fee. If you prefer to rent a computer, please indicate that choice when enrolling in the course.
Computer Hardware Requirements
Your laptop must have a 64-bit processor, Microsoft Windows 7, 8, or 10 installed, and at least 200 MB of available disk space. An external two-button mouse is also recommended.
You must have administrative rights on your computer so that the transmission design exercise software, PLS-CADD/LITE, and the foundation design software, CAISSON, can be installed.
A copy of PLS-CADD/LITE and a copy of CAISSON will be supplied at the start of the course, along with a free temporary license to use this software.
Computer Software Included with Course
The transmission design concepts presented in this course will be illustrated through design examples using the line design program PLS-CADD, developed by Power Line Systems, Inc. You will receive a copy of PLS-CADD/LITE (a sub-set of PLS-CADD), its instructions, and a free six-month license to use the PLS-CADD/LITE program that calculates sags, tensions, loading trees, and thermal rating of overhead conductors.
