Research On Post Evaluation Of Expressway Construction Project

Since 1980's, expressway develops quickly in China, this rapid development speed must encounter some difficult questions while it brings instructive experiences. if the experiences and questions cannot be summarized in good time, it will restrict the expressway healthy and steady development.To sum experiences and lessons, perfect constructed project, improve constructing project, guide intending project, enhance expressway construction project investment decision level and management level, it is necessary to perform expressway construction project post evaluation. As a part of basic construction procedure, expressway construction project post evaluation is indispensable information feedback tache in the project management cycle, In the expressway construction project post evaluation, experiences and lessons in the project management cycle can be summarized, then more project management level can be improved and perfected. Performing expressway construction project post evaluation in China represents that the expressway construction management mechanism enters a sound and perfective stage step by step. researches on this field both at home and abroad, the dissertation makes a detailed and systematic study with sufficient exemplifications about the theory, the methodology and the application of the expressway construction project post evaluation.Firstly, by comparing the different concepts, scopes and the internal mechanisms of construction project post evaluation both at home and abroad and also by reviewing the present theories and methodologies of construction project post evaluation, the dissertation points out that China still lacks a full and normative estimate system, so that theory needs to be linked up with practice, the content to be adjusted, the methods to be innovated, and the manipulate ability to be built up.Secondly, the theory of control-feedback and the theory of sustainable development constitute the theory of dynamic management based on sustainable development, which approaches theoretical foundation of construction project post evaluation with the theory of cost-benefit analysis. Four important methodologies-the methodology of logical framework approach, the methodology of statistics and forecast, the methodology of with and without comparison, and the methodobgy of AHP are being discussed, the theree-stage management system and mechanism are discussed, too.Thirdly, the project process is full analyzed in the dissertation. based on the summaries of existent post-evaluation reports of some highways, according to those...
