About This Item
691-1985 is a technical standard titled Use Guide for Transmission Structure Foundation Design, focused on guidance for designing foundations that support transmission structures in power applications. It addresses the practical engineering considerations involved in selecting, sizing, and evaluating foundation solutions for overhead transmission support systems. For utilities, designers, and project teams, the document can help improve consistency in foundation design decisions and reduce avoidable structural and site-related risks.
About 691-1985
This standard provides a use guide for transmission structure foundation design, which places it in the area of power system infrastructure and civil-structural engineering. 691-1985 is intended to support the design process by clarifying how foundation requirements may be approached for structures that carry transmission lines. In practice, it is relevant where foundation performance, soil conditions, load transfer, and structural stability need to be considered together. The document is most useful as a technical reference for engineers working on transmission projects.
Where is 691-1985 used?
691-1985 is commonly used in planning and engineering work for overhead transmission line projects, especially where tower or pole foundations must be matched to site conditions. It may be applied during route development, foundation concept selection, and detailed design for new builds or upgrades. The guide is also relevant to utility engineering teams, consulting firms, and contractors involved in transmission structure installation, where foundation choices affect constructability, reliability, and long-term support performance.
Importance in practice
In practice, this standard matters because transmission structure foundations must perform reliably under vertical, lateral, and uplift loads while remaining appropriate for local ground conditions. 691-1985 can help improve design consistency and support better coordination between structural and geotechnical work. Using a defined guide also assists with procurement and review, since project stakeholders can align on expected foundation design considerations. For power infrastructure, that can reduce risk, improve safety, and support more dependable service over time.
