In the construction process, real-time quality control and early defects detection are still the most significant approach to reducing project schedule and cost overrun. Current approaches for quality control on construction sites are time-consuming and ineffective since they only provide data at specific locations and times to represent the work in place, which limit a quality manager's abilities to easily identify and manage defects. The purpose of this paper is to develop an integrated system of Building Information Modelling (BIM) and Light Detection and Ranging (LiDAR) to come up with real-time onsite quality information collecting and processing for construction quality control. Three major research activities were carried out systematically, namely, literature review and investigation, system development and system evaluation. The proposed BIM and LiDAR-based construction quality control system were discussed in five sections: LiDAR-based real-time tracking system, BIM-based real-time checking system, quality control system, point cloud coordinate transformation system, and data processing system. Then, the system prototype was developed for demonstrating the functions of flight path control and real-time construction quality deviation analysis. Finally, three case studies or pilot projects were selected to evaluate the developed system. The results show that the system is able to efficiently identify potential construction defects and support real-time quality control.

“…Real-time control of high arch dam construction quality and progress involves collecting quality and progress information about various construction processes with new technologies, including engineering control theory, network technology, simulation technology and data fusion integration [13], then rapidly and efficiently transmitting the information over a network to a server for analysis, and finally helping managers to provide feedback to contractors in real-time. This system is made up of an information collecting layer, an application logic layer and a service decision layer.…”

A complete scheme for solving the key scientific problems associated with high-standard, high-intensity continuous construction of high arch dams was presented. First, based on a coupling analysis of construction system decomposition and coordination for a high arc dam, a mathematical model for real-time control of construction quality and progress that considers complex constraints was developed. Second, a method of progress control was proposed based on a dynamic simulation. Third, a dynamic quality control mechanism was established based on construction information collected using a PDA. Fourth, a system for integrating collected information, progress simulation and quality control analyses under a network environment was developed. Finally, these methods were applied to a practical project to show that each aspect of a construction process can be managed effectively and that real-time monitoring and feedback control can be realized. Our methods provide new theoretical principles and technical measures for quality and progress control in the high arc dam construction process. construction quality, construction progress, dynamic simulation, real-time control, network, high arc dam Citation: Zhong D H, Ren B Y, Li M C, et al. Theory on real-time control of construction quality and progress and its application to high arc dam.High arc dams are generally located in mountainous regions or in gorges. These areas have complicated geology, steep terrain, deep valleys, high stresses and limited space. The length of the construction period and the safety of whole project are directly affected by construction progress and quality of high arc dam [1]. The construction process is complicated and dynamic. It can only be semi-structured and involves randomness, uncertainty. This uncertainty is influenced by many factors including the natural environment, structural form of the dam, technology, organization modes, machinery and building materials. This complex construction process cannot be represented by a simple mathematical model. Real-time control technology is an effective method for studying the technical problems associated with high-standard, high-intensity continuous high arc dam construction. Construction quality and progress control are important issues both domestically and internationally. By combining Auto CAD, P3 and ArcViewGIS, Poku et al. [2] developed the PMS-GIS system, which shows the progress of housing construction in a dynamic 3D image. Leung et al. [3] developed a construction site video monitoring system that integrates a wireless network, network cameras and a web-based collaborative platform for controlling building construction quality and progress. Xiao et al.[4] effectively controlled bridge construction quality using fast internet-based data acquisition and transmission as well as control decisions.

Utilizing finite element simulations of dams during each phase in the construction process, the temperature field and stress field at the t...

The conventional quality control method of core rockfill dam construction exhibit difficulty controlling compaction parameters accurately or ensuring construction quality. This is because it is easily influenced by human behavior or lack of adequate management. We therefore establish the timely monitoring indexes and control criteria of compaction processes by considering the characteristics and quality requirements of high core rockfill dam construction. Based on the established indexes and criteria, integrating GPS, GPRS and PDA technologies, a real-time compaction quality monitoring method is proposed. The relevant key techniques are proposed as well, including automatic collection of information and a graphic algorithm for rolling-process visualization. By the proposed method and techniques, a real-time monitoring system is provided to realize the precise automatic online entire-process monitoring of compaction parameters, including compaction pass, rolling trajectory, running speed of roller, vibration status and rolled pavement thickness. The application of the Nuozhadu project shows that the proposed system can control compaction parameters effectively and ensure better construction quality. Therefore, it might become a new way towards construction quality control of high core rockfill dam. core rockfill dam, compaction quality, real-time monitoring, quality control Citation:Zhong D H, Liu D H, Cui B.
