In the traditional experiment teaching of civil engineering, students’ practical ability can not be comprehensively cultivated due to their rareness of participating activity. As a result, undergraduates’ innovation spirit is restricted. Based on features of different professional laboratories in Faculty of Infrastructure Engineering, Dalian University of Technology, the opening modes for undergraduates of each grade were proposed aiming to cultivate their innovation abilities. Important problems for opening the professional laboratory were firstly addressed as follows: reforming the management system, the cultivation objective, and assessment method of undergraduates. Entering laboratories, joining in research programs, and reforming the thesis instruction mode were the main modes of opening laboratory to undergraduates.
