• Otto J. Lynch

  President and CEO

  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

  Director of Engineering Services

  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.
