Quality is one of the most vital aspects of a construction project, and inspection is the most important task in construction quality management. Despite the application of advanced information technologies, the omission of check items and in-efficiency of entering inspection results from paper-based inspection records into computers and collaboration among the construction stakeholders remain to be major problems. This paper proposes an approach to make the process of construction quality management more effective and collaborative by developing a system based on the integrated application of building information modeling (BIM) and indoor positioning technology. First, the system requirements of the collaboration platform are analyzed based on the standards for construction quality inspection in China, the technologies to be used for its implementation are justified, and a process model for the collaboration of multiple stakeholders is established. Next, the system architecture is developed, and the algorithm for generating inspection tasks and the technique for integrating with indoor positioning technology are formulated. Finally, the implementation of a prototype system is presented, and the effectiveness and efficiency of the approach for construction quality management are verified by using the system in an on-site test.

With the concepts of Smart City attracting the industry, the method of managing spatial information has become a hot research topic. Relating to this topic, GIS and BIM are two critical technologies. Although the application of GIS has a long history and BIM has also developed for over 10 years, their integrated application starts a new direction and is still at the early exploration stage. To better understand this newly expanded field, we review previous works in the field from the perspective of research and relevant application platform. Based on that, directions of future research are discussed. [ABSTRACT FROM AUTHOR]
