ABSTRACT
A progressing transmission construction boom has notably affected the availability of qualified construction personnel and equipment along with other resources for transmission construction projects. One solution to the limited outages and resources for foundation construction is prefabricated foundations (PFF). The most common existing applications of PFF focus on the support of transmission line structures primarily in the form of grillages and direct embed foundations. In 2017, our team conducted three pilot projects utilizing PFF designs for both station and transmission line projects. Over the course of these pilot projects, our team observed and documented significant improvements reducing the cost of foundation construction, minimizing construction schedules, and improving field worker safety. PFF provide varying and circumstantial advantages over conventional cast-in-place foundations when optimal site-specific soil conditions are present for the support of station and transmission line structures.
