COMING IN JULY 2026

Sponsored by the Task Committee on Overhead Power Line and Substation Foundations of the Committee on Overhead Power Line Structures of SEI Technical Community the Structural Engineering Institute of ASCE

Overhead Power Line and Substation Foundations: State of Practice, Basics, Type Selection, Geotechnical Topics, and Specialty Analysis, MOP 160, provides an overview of the best practices and recommendations regarding the analysis, design, and construction of electrical overhead power line structure and substation structure foundations and summarizes the most common foundation design considerations.

Topics include

• Basics of overhead power line and substation foundation design,
• Foundation type selection,
• Subsurface geotechnical exploration,
• Geotechnical design parameters,
• Special foundation design considerations,
• Seismic design,
• Evaluation of existing foundations,
• Survey results,
• Below grade-corrosion protection of foundations
• Concrete and grout, and
• Concrete foundations anchorage design.

Companion manual to MOP 161, Overhead Power Line and Substation Foundations: Design Loads, Strength Factors, Threshold Criteria, and Design/Construction Methodologies, MOP 160 will provide comprehensive information to engineers with varying foundation design experience to help make informed, uniform decisions regarding transmission line and substation foundations.
