Large amount of construction resources and their scattered locations in a civil construction site make it extremely difficult for project managers to effectively utilize the resources. In order to manage construction resource effectively, a Radio Frequency Identification (RFID) technology was used in this research. RFID tags for metallic objects were attached to structural components used in a cable-stayed bridge. The RFID reader and antennas were installed at the construction site for tracking the structural components and the acquired data were transferred to the head office via Local Area Network (LAN). The proposed RFID system enabled real-time monitoring of the construction materials in the civil construction site.

Construction progress monitoring is a critical task for construction managers. Traditionally, site superintendents walk the construction site to verify the progress report and understand the current state of construction processes. To get rid of the time consuming process, this research proposes a construction progress monitoring system comprised of a network type closed-circuit television (CCTV) camera, a wireless local area network, and image processing techniques. A civil engineering construction site was selected and the system is able to capture the images of the construction processes. In this paper, the hardware architecture of the system and its initial application results are presented with some promising outcomes.
