Research On The Success Criteria Of Large Scale Construction Projects

With its economy's rapid development, China has a large demand for large scale construction projects. The enlargement of the construction projects has caused increasingly serious social problems during the constructing and managing process. And the smooth implementation of large scale construction projects depends on all participators' vigorously supports for their characteristics of huge investment, long construction period, wide influence, numerous participators and strong system, as well as other stakeholders of the project. Therefore, we need to apprise all the relevant sides of the project base on their goals' realization. The determination of success criteria is the foundation of appraising the large scale construction projects. Only if the criteria determined, we can carry on the accurate, objective and fair appraisal of the projects. So far, the analysis of construction project from the stakeholders' angle has just at the stage of exploration. There is vital significance to explore the success criteria of large scale construction projects from the view of stakeholders. It can speed up the engineering project management mechanism reform, raise the construction management level and increase the project investment benefits.This article carries on a thorough research on the success criteria of large scale construction projects with the stakeholders' theory, and establishes a scientific and comprehensive appraisal frame. The appraisal index from the stakeholders can well break through the original appraisal frame of the financing-centered economic dimension and avoid the construction enterprise's lacking foresight action. Meanwhile, the index can guarantee the scientificity and comprehensiveness of the success criteria so as to promote the overall efficiency of the projects. The application of the theory on success criteria of large scale projects is an innovation with important practical guiding significance.From the view of the projects whole life cycle, large scale construction projects' success should be regarded as a system behavior with the aim of satisfying all the stakeholders' benefits as far as possible, and optimizing the performance of the triple bottom line including the economy, the society, and the environment. Therefore, we should introduce system-thinking into the research of success criteria and construct the synthetically three-dimensional appraise model based on the whole life cycle, the triple bottom line and the success dimension of large scale projects. It has not only fully manifested the core value of the projects' success, but also enhanced the harmonious degree of large scale projects.Based on the domestic and overseas research results of the stakeholders, this paper determines the key stakeholders of large scale construction projects through the questionnaire survey method. Furthermore, the method has been classified by three dimensions of urgency, influence and the initiative which based on the SPSS statistical method and field effect method. The result shows that there are great differences between different attention degrees of the stakeholders. Effective communication and balanced benefit requests are needed to realize the success criteria of the projects. Upon which, this study carries on an empirical analysis of the benefit requests of the stakeholders and provides the sorting benefits request of the stakeholders. On the other hand, in order to clear the identification degree of the stakeholders, it carries on a comparative analysis of their different demand sorting.The success of the projects largely depends on whether the success criteria can realize the optimization of the benefits request of the stakeholders. Based on the benefits request of the key stakeholders, combined with the review of success criteria, this paper expounds the success criteria of projects from three aspects--the time dimension, the stakeholders dimension and the project objective dimension. Considering the biggish differences of the success criteria during different construction stages, this paper carries on a respective statistical classification for the success criteria of large scale construction projects at the stage of decision-making, implement and operation, and then establishes a modified model through the factor analysis method and the main composition of analysis method.The key to guarantee the large-scale project success is to balance the benefits distribution of interest bodies. By analyzing the relationship between project success and the scale, and the relationship between dependence and diversity of project interest bodies, this paper constructs the Large Scale Engineering Project Success Criteria-Planguage (LPSC-P) System. And considering the different evaluation time points, it builds the LPSC-P-D system at project delivery and the LPSC-P-O system after a time of project operation. This system makes the success criteria of large-scale project much more practical, and its correctness is verified by the qinghai-tibet railway project. Judged by the LPSC-P System, the qinghai-tibet railway project is a very successful project not only at the delivery, but also after a time of operation.
