In the electric transmission industry, many professionals face complex challenges when it comes to foundation design and retrofit. Engineers, architects, and construction experts often encounter issues related to structural integrity, soil pressures, and the proper installation of foundations. Additionally, ensuring the longevity and safety of structures, as well as addressing issues such as corrosion and grounding, are critical concerns. Without a solid understanding of these aspects, there’s a risk of costly errors, structural failures, and compromised safety standards.

The Transmission Structure Foundations Design course provides a comprehensive overview of foundation design and retrofit. The course equips participants with the knowledge and skills required to analyze soil pressures, implement proper anchor bolt load transfer, and make informed decisions about rebar placement. Additionally, it covers essential topics such as backfill design, corrosion protection, and grounding considerations, ensuring that structures are not only safe but also durable. With this workshop, professionals are better equipped to deliver high-quality, long-lasting, and secure construction projects, meeting industry demands and utility expectations while reducing the risk of structural failures and costly rework.

• Analyze soil pressures surrounding existing and potential transmission structure foundation locations
• Define and differentiate Caisson Foundations, Direct Embedded Foundations, Grillage Foundations, Gravity Foundations
• Explore foundation retrofit designs
