As buildings become taller and more complex, establishing clear evacuation routes becomes very important in the event of a fire or other emergency. In this paper, Wireless Sensor Networks (WSN), Radio Frequency Identification (RFID) and real time escape route guidance are integrated to accomplish a real-time fire evacuation system to guide along an evacuation route. When the emergency event occurs, the system provides evacuation route guidance to people for them to be able to avoid danger. Moreover, in the proposed system, an intelligent evacuation route is provided by indicating in digital signage the best evacuation route as well as pertinent information to improve the chances of survival for users. The proposed system also supplies real time environmental information to fire fighters assuring better efficiency in their rescue operations.

The traditional construction schedule planning methods are mostly based on the project activities list broken down by the experienced engineers who primarily analyze the work content of construction drawings, and the activity durations estimated by simulating the construction process according to the conditions of the construction site. However, such an approach does not only give hard time the new engineers without experience, but is also unable to capture the dynamic risk factors while estimating the construction duration. As a result, the planned schedule is usually inaccurate and ineffective. To tackle the abovementioned problem, this paper presents a BIM-based Visual Risk critical path Scheduling System (BIM-VRcpSS) to assist the construction scheduler in developing a more accurate and effective schedule. The proposed BIMVRcpSS provides functions of risk-based Critical Path Scheduling Method (R-CPSM) based on seven different risk levels. It also equips the construction schedulers with a 3D BIM visual simulation tool to better estimate the activity durations compared with the traditional 2D approaches. Moreover, with the aid of a cloud data based system, the construction schedulers are able to fine-tune duration estimates by considering the impacts of different risk factors without spatial and time limitations. As such, the proposed BIM-VRcpSS can increase the duration estimation accuracy of construction activities, and improve the traditional scheduling approaches.

In recent years, Taiwan launched railway reconstruction projects to promote urban renewal and rural development. As the area of reconstruction projects is adjacent to the railway in operation, there are hidden risks to construction personnel and safety of the railway operations. The composite pier engineering method can improve construction safety and reduce risk. This paper presents a case study and discussion on risk management to provide the lesson learn for reference.

The reinforced concrete is widely used in the current building system; there are several finishing-free concrete surface techniques for the time being, but the undesirable phenomena affecting flatness and smoothness, such as air voids, pores, honeycombs and cold joints on the completed surface often appear. For this study, the Vibration Degassing Machine (VDM) was created and patented which is used to conduct the second partial ramming modification on the interfaces between concrete and formworks that eliminates the air voids on concrete surface efficiently and reduces the pits after removing formworks to enhance the smoothness on concrete surface which ideally presents the beauty of original design.

Tourist hotels are part of service industry, thus fire safety issues are particularly important. Due to the complexity of the hotel’s construction, most of the tourists are not familiar with the environment. In case of fire it would be hard for them to evacuate the building. Therefore, this study collects and organizes documents, regulations and cases. By applying risk management this study summarizes the key items of the fire safety risk assessment application are: Whether fire evacuation facilities have been blocked and major risk items must be examined daily.
