This study summarized the case study of a course development of introductory engineering design considering the characteristics of civil and environmental engineering. The course mainly depends on conducting the design projects. The self-developed text book for the course consists of learning and activities of the core elements for the creation and decision of ideas and two independent design projects. Especially, the design project drew from a survey of students majoring in civil and environmental engineering and is well knitted to help students obtain the potential for soft-landing at higher major courses.
