History of the Bell Bottom Pier

In 1916, while observing the construction of foundations for a residence, Willard Simpson became enthralled by local well driller, Ed Duderstadt, drilling deep holes with an 18-inch diameter auger powered by a mule walking around in a circle. He enlisted Duderstadt to drill similar holes (down to hardpan) for a foundation system he was experimenting with. Filling the slender cylindrical hole, which bypassed the site's unstable upper soils, with concrete and re-enforcing bars. Simpson used the resulting piers as his foundation supports, and the drilled pile (or pier) foundation system so much in use today was born!

Simpson also pioneered the concept of reaming out the bottoms of these drilled shafts to enlarge their bearing area to better carry increasingly larger building loads. In the early days, these bottom-belled piers were accomplished by lowering a construction worker down the shaft who then formed the under-ream by hand. Later, in the 1920's Simpson and Duderstadt collaborated in developing a first-of-its-kind mechanical device to under-ream pier shaft bottoms.
