Chapter 7
Foundations
Publication: Substation Structure Design Guide: Recommended Practice for Design and Use
Abstract
This chapter identifies various types of foundations that are commonly used to support substation equipment and structures, discusses geotechnical considerations for the design of substation foundations, and provides design considerations that may be unique to construction with a new or existing substation. It focuses on the design of new, cast-in-place concrete foundations. NAVFAC, while an older document, contains a wide breadth of information and considerations for the design of shallow and deep foundations. Choosing the appropriate type of deep foundation is dependent on the subsurface conditions and local experience and practice. The chapter provides additional design considerations. Such considerations can affect the design and performance of foundations and, where applicable, should be addressed by the geotechnical testing firm with recommendations for design or mitigation in the geotechnical report. Utilities may have unique load combinations and criteria for the design of substation structures and foundations based on regulatory codes, operational requirements, and regional experience.
