Sticky Situation
Having just been grouted minutes ago, the top half of caisson no. 238 gets pulled out along with its casing at 9:02. "That's about the worst thing that could happen," says Jones. The crew will spend the rest of the morning re-drilling the shaft and installing a new foundation. Occasionally, concrete seeps outside of the corrugated liner during a pour, causing the "sticky" problem.
