Engineering Technicians read and review project drawings and plans to determine the sizes of structures, observe project sites and evaluate contractors’ work to detect problems with a design, and help to ensure that project construction conforms to design specifications and applicable codes. Also, Technicians confer with engineers about preparing plans, evaluate field conditions, and develop plans and estimate costs for constructing systems and operating facilities. During and after projects, Engineering Technicians use computer design software under the charge of engineers, set up and help maintain project files and records, and prepare reports and document project activities and data.
