Pile footings may be square or rectangular in shape, but may also be which other shapes depending on the number of piles in the group or the arrangement?

Explanation:
Pile caps are shaped to fit the layout of the piles they tie together. When piles are arranged in patterns other than a simple rectangle, the cap follows that pattern. For three piles, a triangular cap fits the arrangement; for six piles arranged around a center, a hexagonal cap is efficient; for eight piles in an octagonal layout, an octagonal cap makes sense. This geometry helps distribute the load evenly among piles and keeps the reinforcement practical around the cap.
