Poorly Executed Surveys: Hidden Risks in Energy Transmission Projects

Geotechnical investigation through percussion drilling (Standard Penetration Test) is a critical stage in the development of transmission line projects, being essential for the proper design of the foundations of metal structures. Obtaining accurate data on subsurface conditions along the route allows for the geotechnical characterization of the terrain, supporting design decisions based on technical and regulatory criteria. In summary, the geotechnical survey not only technically underpins the foundation design but also contributes to the technical, economic, and operational feasibility of the project, being indispensable for the safety and durability of transmission lines. This study will demonstrate two important examples of how a geotechnical investigation conducted in accordance with…
