Abstract:Taking the Shenzhen Wanghai Road Expressway Reconstruction Project as an example, the important factors affecting the promotion of major projects are analyzed. These factors are the necessity and urgency of project construction, the construction duration, the function orientation, the traffic volume prediction and the engineering scale control, the coordination with other related major projects, the social stability risks and the engineering investment. Based on this, a large amount of scheme optimization and argumentation work was carried out, which eventually enabled the project to be retained and continue to advance. The successful experience of this project can provide reference for similar projects.
