This paper presents recent developments and applications of three- (3-D) and four-dimensional (4-D) modeling on two transportation projects and their added value for constructability reviews. Transportation projects are characterized by challenges, such as design complexity, right-of-way acquisition, utility relocation, and traffic management, which truly need to be addressed by constructability reviews so as to make projects successful by minimizing delays, cost overruns, change orders, and so on. The 3-D and 4-D computer-aided drafting (CAD) models are new emerging tools that can tremendously aid constructability reviews. Although the models are extensively used in building projects for this purpose, their use in transportation projects is limited. The 3-D and 4-D CAD models in building projects could also be applied to transportation projects. The 3-D and 4-D CAD model applications developed for the two transportation projects in this paper emphasize the value added by this new technology to communication, technical design checking, construction planning, and work area management applied to transportation projects.
