Using sonotubes in caisson construction primarily simplifies the pouring process. Sonotubes are designed as cylindrical forms that facilitate the pouring of concrete into a specific shape, ensuring that it maintains its form while it sets. This ease of use helps minimize complications during the pouring phase, allowing for a smoother and more efficient workflow.

Their design ensures that the concrete retains its consistent shape and dimensions, which is critical for structural integrity once cured. Additionally, the lightweight nature of sonotubes makes them easy to transport and handle on-site, further simplifying the construction process.

While the other options touch on attributes of sonotubes, they do not capture the most significant benefit related to the construction workflow and efficiency offered by these forms. For instance, although sonotubes do contribute to structural integrity once filled, that’s an indirect benefit of their primary role in shaping and simplifying the caisson construction process.
