Plans for projects involving more than ________ cubic feet require certification by an architect or an engineer registered in Indiana.

The requirement for projects involving specific cubic footage to be certified by a registered architect or engineer in Indiana is in place to ensure that design and construction standards are met for larger-scale projects. When a project exceeds 30,000 cubic feet, it is perceived as substantial enough that the complexities involved necessitate the oversight of a professional who is intimately familiar with building codes, engineering principles, and safety regulations.

This threshold is established to protect public safety and ensure that structures are designed and built correctly. Projects below this threshold may be deemed simpler or more manageable, potentially allowing less stringent oversight. Therefore, the 30,000 cubic feet figure serves as a benchmark for the level of expertise required to certify the plans, aligning with state regulations that emphasize safety and accountability in construction practices.
