Civil Designers use computer-aided design (CAD) programs to draft, produce, scale and fine-tune drawings and maps for key infrastructure and construction projects. This may include roads, bridges, railways, earthworks, and commercial, industrial, and residential developments.

Their tasks and duties include preparing conceptual and formal design drawings using CAD programs or other engineering software for review by engineers, interpreting civil engineering drawings and building plans, preparing designs for land subdivisions, road infrastructure, drainage, sewer and water systems, ensuring designs take into account associated planning, survey, traffic, electrical and landscaping requirements and reading maps and land surveys to note land grading, nearby structures and other factors that could affect the placement of new installations.
