A Visualization System for Improving Managerial Capacity of Construction Site

In this paper, we propose a solution to improve the construction management capacity. Our solution contains three parts: a Location Identification System, a Work Progress Management System, and a Statistical Analysis & Visualization System. The Location Identification System locates the equipment and the worker inside the construction site, by using Bluetooth Low Energy (BLE) Beacon and Android Smart Phone Device. The location information is sent to the server that away from the site. The Progress Management System (PMS) collects the work progress information and transits the information to the server through a wireless network. The Statistical Analysis & Visualization System, which runs on the server, computes the distribution of each worker and saves the result as a heat map density. It also computes the progress ratio and the deviation ratio, according to the original work plan. At last, the system displays the progress ratio and the worker distribution together for each area in the

Development of Work Traceability System Using RFID Technology in Plant Construction Management

Abstract: In this study, we evaluate the applicability of RFID tags and developed material management system and the work traceability system in plant construction. The examination results indicate that RFID tags and GPS systems were usable enough. About the work traceability, we solved administrative problems of the digital photographs and suggested a method to prove an original or an imitation of the digital photography. And, it was able to reduce time to search for construction materials by the developed systems and time to make a report using digital photographs.
