Is casework considered a type of millwork in commercial projects?

In commercial projects, casework is often included within the broader millwork scope for simplicity, especially when one shop fabricates both. Contractually, it may be labelled as millwork even though the construction approach is more standardized.

From a technical standpoint, casework usually follows preset sizes and details, while millwork involves more customization and site coordination. The distinction matters most during detailing, pricing, and installation, where assumptions about tolerances and flexibility can differ.
