I work in an industrial facility where all of our 13.8KV incoming feeders are routed in duct banks with large concrete manholes for pulling and splicing feeder taps. These manholes are spaced at approx. 600' intervals. I am working to add two new incoming feeders. We have not added any duct bank since I started working here, so I don't have any experience. Are there more economical solutions than the concrete manholes? I have had one contractor mention fiberglass manholes, but I don't know anything about this option. Any ideas would be greatly appreciated.
