Application Deadline: Open until filled
The primary purpose and responsibility of a Civil CADD Technician is to utilize computer aided design drafting (CADD) to design accurate plans for a road project and other civil construction projects. From preliminary survey of a project with modern surveying instruments to total design on a CADD platform to the finished job of staking/inspection of a project. One function of a CADD Technician is to organize data from surveys and other sources to be efficiently used and permanently stored for reuse. Will function as a CADD operator and/or survey crew chief for Public Works Department projects as needed.
