For a long time, the traditional quality management in the construction industry is divided into three parts, quality assurance system construction, on-site quality acceptance and quality defects management of finished products.The quality management of this model is carried out in the form of construction tasks, in the strict sense, the quality process management of the engineering structure itself is not carried out.With the increasing application of BIm in the construction industry, the process of building industrialization continues to advance.By means of structural components, standardized components, production processes, fine matching procedures and acceptance items.So that it is possible to explore the management of quality acceptance based on component.

CRTS Ⅲ slab ballastless railway track is an innovative slab ballastless track with completely independent intellectual property rights of China. As a new structure type of line construction for passenger special line, a complete set of construction techniques has been summed up.With the development of CRH (China Railway High-speed) Technology, the application of CRTS Ⅲ slab ballastless railway track will be increasingly more extensive. Currently, with the continuous application of new technologies such as BIM (Building Information Modeling), IoT(Internet of things), big data, and etc., the construction site management is also improving in refinement, information, scientific degree. The development of delicate adjusting information management system for the slab ballastless railway track enables the storage of the construction data in track plate installation process in a true, complete and timely manner, which is later used for analysis and application to realize the full life cycle management of slab ballastless track construction in real sense. The system is of great construction guidance value and technical research value.

According to the needs of the construction quality supervision, we construct the index system of for engineering quality comprehensive evaluation. Base on the analysis of single project quality evaluation index, regional engineering quality evaluation index and attribute quality index and so on, the whole city engineering quality level is evaluated. A engineering quality comprehensive evaluation management platform is developed, which is working in wuhan's Quality Supervision Station and provide basis for decision-making for quality supervision and management.
