Keeley Civil Spotlight: Casey West Transmission Line

Eastern Illinois | New Construction | June 2023

The Keeley Civil Team was called upon by a trusted partner for the construction of a new Transmission Line from Casey, IL to West Union, IL. This 22-mile, 345kV Transmission Line was completed on time and on budget.

Construction of this Transmission Line included using culverts and wood matting to provide easy access to structure locations and 36 cast-in-place reinforced concrete pier foundations. These 36 pier foundations consisted of four, 3-pole structures to tie the transmission line into the new substation; and eight, 3-pole terminal dead end storm resiliency structures. Throughout the entire project, 3,500 CY of concrete and 450,000 pounds of rebar were used. The Keeley team was able to self-perform the entire scope of work, ensuring a timely, safe delivery.

Efficient and effective communication was paramount for the success of this project. Concrete had to be hauled across many farm fields to the final pier locations, so the Keeley team built trusting, strong relationships with local landowners to ensure all transportation did not harm any land. Secondly, the easternmost structures were located near the Wabash River. Due to unforeseen weather conditions, the team had to mitigate flooding to maintain quality construction. Finally, the initial electrical outage needed to install foundations under the live line was rescheduled, causing a delay in beginning the project. However, due to Keeley’s Transmission Line expertise, self-perform capabilities, and dedication to exceeding expectations, the final project was completed ahead of schedule and to the utmost satisfaction of the client.
