This Library page was created to compile, in one location, articles and web links containing information relative to the survey/engineering procedures utilized by the field offices here in the North Carolina DOT. Many of these are copies of HTML documents from various sites on the web and were placed here for the content of information. Therefore, the navigation menus on these copied pages will not work. If anyone should find information that they think needs to be included onto this page, please contact the Project Data Support Group to see if we can acquire permission for it.
