According to the recent trends which are the diversity of customer requests and the multi-function of buildings, A construction company's business has converted from the producer-oriented approach to the consumer-oriented approach. Therefore, each construction company is continuously trying to improve the quality level as a way of corresponding to customer needs in these changing situations. The quality is one of the main management targets which judge the success of a project along with the schedule, the cost and the safety. As construction companies execute the quality management which they aimed at, it should be completed within the optimum schedule and the limit of the budget. Accordingly, the importance of the construction site management to complete a project is continuously increasing. The construction site management is the systematic method to perform the project goals such as the quality improvement, the cost saving and the safety management, which organically operate one another, by procuring the manpower, the material and the machine in the right time. Specially, as the construction industry has based on the construction site, the establish of systematic construction site management, which can effectively correspond sudden changes of the construction business environment, is essential to maximize the construction productivity. On top of that, the necessity of the quality management method is increasing to accommodate customer needs more spontaneously in the construction site. These endeavors could guarantee their competitive power.

Various safety measures have been established and implemented in order to reduce construction accidents. However, statistics data on at construction sites still show higher accident and mortality rates than other industries. As a result of investigating the causes of accidents occurring in the construction industry, most accidents resulted from the failure of the system. Therefore, the existing safety management system of the construction site is monitored so that it operates properly in the field, and it is an important factor to actively participate in construction work. In order to overcome this, the government emphasized on-site inspections and planning and implementation confirmation by public institutes to ensure the effectiveness of the safety management system through amendment of the Construction Technology Promotion Act, but the orderer' safety capability and manpower are insufficient at present. Therefore, in this study, the safety management system, such as design for safety, safety management plan, safety check, safety management cost, etc. specified in the Construction Technology Promotion Act, is regularly checked and confirmed to improve the effectiveness of the safety management system as well as to improve the safety management system of the construction site by deriving measures to strengthen the public function of the government.

On construction sites, it is important to monitor the performance of construction equipment and workers to achieve successful construction project management; especially, vision-based detection methods have advantages for the real-time site data collection for safety and productivity analyses. Although many researchers developed vision-based detection methods with acceptable performance, there are still limitations to be addressed: 1) sensitiveness to the shape and appearance changes of moving objects in difference working postures, and 2) high computation time. To deal with the limitations, this paper proposes a detection algorithm of construction equipment based on Integral Channel Features. For validation, 16,850 frames of video streams were recorded and analyzed. The results showed that the proposed method worked in high performance in terms of accuracy and processing time. In conclusion, the developed method can help to understand useful site information including working pattern, working time and input manpower analyses.

Unsafe behavior is one of the major causes of construction accidents. Managing the behavior of workers in real-time is difficult and requires huge manpower. In this paper, a new real-time locating framework is proposed to improve safety management by collecting and analyzing data describing the behavior of workers to identify habits that may lead to accidents. The aim of the study is to identify working habits of workers based on their location history. Location data is used to compare with that of other workers and equipment. The results indicate that the reuse of real-time location data can provide extra safety information for safety management and that the proposed system has the potential to prevent struck-by accidents and caught-in between accidents by predicting unwanted interaction between workers and equipment. This adds to current research aimed at automating construction safety to the point where the continuous monitoring, managing and protection of site workers on site is possible.
