Civil engineering technicians typically do the following:

• Read and review project drawings and plans to determine the sizes of structures
• Confer with engineers about preparing plans
• Use computer aided design software under the charge of engineers
• Evaluate pre-construction field conditions
• Observe project sites and evaluate contractors' work to detect problems with a design
• Test construction materials and soil samples in laboratories
• Help to ensure that project construction conforms to design specifications and applicable codes
• Develop plans and estimate costs for constructing systems and operating facilities
• Prepare reports and document project activities and data
• Collect data and prepare analyses
• Set up and help maintain project files and records

Civil engineering technicians typically work under the charge of licensed civil engineers. These technicians generally help civil engineers, performing some of the same tasks as the engineers. However, because they are not licensed, civil engineering technicians cannot approve designs or supervise the overall project.

Civil engineering technicians assume varied duties on the job. They sometimes estimate construction costs and develop specifications. Other times, they prepare drawings or survey land. They also may set up and monitor various instruments for traffic studies. These technicians' duties often require familiarity with and use of various computer programs to design projects, collect and analyze data, prepare correspondence and reports, and manage file systems.
