What is CNC?

Definition of CNC in Construction
This is the architectural designation that will mostly be used to identify concrete as the material. Unfortunately there is no set or established nomenclature that is consistent on all documents throughout the United States. One architect or engineer may indicate concrete as conc. or simply spell out the entire word. It is always recommended that the glossary of specific terms for a particular project be reviewed to ensure understanding of the nomenclature used on this specific set of construction documents. Once the establishment of the nomenclature is established for the project, remember that there are always variations on a theme and the architect may identify concrete on a project in one manner and the structural engineer in another. It will require some experience and insight to establish the sensibility of all of the construction nomenclature on several projects from various architects and engineers.
