Precast columns are often built with what features cast into their sides?

Precast columns are often designed with haunches or shelves cast into their sides to provide structural support and facilitate the attachment of other building components. These features are essential for enhancing the overall stability of the structure, particularly in multi-story construction. The haunches can help with load distribution, offering a more robust connection point for beams, floors, or other attachments.

By incorporating these elements during the precasting process, it streamlines construction and minimizes the need for additional onsite modifications. This feature also helps in accommodating mechanical and electrical systems that may need fastening in certain locations. Overall, the use of haunches or shelves contributes to the efficiency and integrity of the construction process.
