OVER THE MOUNTAIN AND THROUGH THE SWAMP Foundation Alternatives for Extreme Access Conditions

摘要

The Koolau-Wailupe project illustrates micropiles as a deep foundation solution for electric transmission structures in rugged terrain and on steep slopes, featuring low overhead clearance. Where conventional construction methods were not possible, and the ability to construct the foundations exclusively by helicopter support provided the owner with a constructible alternative. Leveling platforms and segmented materials offered additional benefits to construction, and the use of innovative steel pile caps enabled the project team to work flexibly around a variety of weather-related challenges.
