Based on IoT (Internet of Things) where its concept contains providing convenience to human life by connecting every objects around us, numerous projects have been done in civil engineering field. This paper has conducted the basic study on adopting IoT sensing technology and network system into harbor.

The objective of this study is to develop a bridge maintenance system utilizing NFC(near field communication) technology and mobile devices to enhance maintenance efficiency. The system consist of web program and mobile application. Web program was developed using java programming language that is object-oriented, and mobile application was developed using hybrid app that runs inside of a native container and leverages the device’s web browser to display locally hosted HTML pages. In additionally, this system had been designed to improve system usability and on-site applicability for convenient GUI (graphic user interface) environment.

The research was conducted for making accident-free and effective construction site to improve the smart construction site management environment by using new developed technology such as Internet of Things, Smart phones and GPS Tracking. The study recommends new construction accident prevention system using smart phone.

Quality control of concrete during its curing process is crucial when it comes to reaching the ideal strength. This paper presents the basic study of optimizing concrete curing process by using Arduino platform based on the maturity method. The research has suggested a quality control of curing process by visualizing the curing temperature and its strength from web. The maturity method was coded into the web which allows managers to monitor regardless their locations.

Currently in Korea, there are about 1200 dam (height 15m or more) Recently, natural disasters are caused by abnormal climate and they have caused a lot of damage. but many institutions about dam don’t resolve this problem because dam was owned and managed by other institutions. Therefore, to develop Web2.0 Smart Management System, it will be possible to combine different institutions and do efficiently intelligent management of dam.

In this paper, And improve the performance of the current bridge inspection systems Intelligent sensor platform of the bridge, Bridges Management and Control, U- disaster warning, Intelligent prevention, etc. The intelligence to maximize the capabilities of the existing bridge inspection systems It proposes an efficient management plan through a ubiquitous sensor network. Since these services are very important to minimize situations where the bridge disaster casualties. Through RFID, RTLS and smartphones, IT technology and sensor fusion, etc. Build bridges to the entire inspection time and unattended automated disaster detection system minimizes the time to invest in bridge inspection and efficiency is to be maximized.
