SPIDACalc Structure Analysis Software has revolutionized the world of pole loading and has made its mark in the utility industry. Today, SPIDACalc is implemented in over 225 companies across the United States, Canada and Caribbean. Recognized as a user-friendly software, SPIDACalc focuses on the integrity and construction of utility structures.

SPIDACalc utilizes the latest software technology and a geometric nonlinear finite-element analysis engine to drive pole loading, pole strength and guying analyses to power clearance evaluations and structural calculations. These analyses are configured to test against a variety of safety standards including the National Electrical Safety Code, California’s GO95 and Canada’s CSA standards.
