Construction Standards, Specifications & Standard Details

Effective July 1, 2018, the City will adopt the North Carolina Department of Transportation (NCDOT) standards as its official Construction Standards. 

The City will no longer reference the specifications issued in 1991 (retained below).

The City will continue to utilize the construction details listed below, as they are unique to City construction and are not adequately addressed in the NCDOT Standards.  Conflicts should be addressed by senior staff in the Engineering Inspections or Development Review groups.
