-All temporary structures at the construction stage are collectively called falsework. As part of the falsework, the importance of system shoring support (SSS) is often overlooked in construction projects, thus causing increasing accidents from SSS collapse. The 2014 occupational accident statistics of the Council of Labor Affairs show that most occupational accidents occurred in the construction industry, and fall and collapse were the most common accidents in the construction industry in Taiwan. Although the SSS is commonly used in construction, no well-defined instruction for the installation and required safety facilities for SSS have been established to provide a dependable guide. The status of SSS used in falsework of construction projects and the types of potential accidents and relevant examples will be investigated. With building information modeling (BIM), this study defined the relevant SSS facilities with the 3D modeling of BIM. This research drew the actual status of the erection of SSS on the construction site with the Revit from Autodesk to provide a communication platform for engineers, SSS contractors, and labor safety and health personnel. The corresponding preventive measures in terms of safety passages and stairs have been proposed for the reference of engineering personnel in construction site. Through the help of this study, the construction falsework safety can be enhanced and the accidents of SSS can be minimized.

-The content of fire cause investigation is not only the fire prevention as reference but also the significant gist to improve firefighting. But in point of fire site investigation, mostly were using handwriting document for recording information at present, obviously lacking with carrying convenience and recording instantaneity. Meanwhile, after causing of fire, the investigation work also utilize building information captions to display the original fire scene and identify the ignition point. But traditional two dimensions floor plan is limited to provide architectural spaces information, usually can't represent the actual appearance of the building. If using three dimensions Building Information Modeling (BIM) outputting the relevant elevations, perspectives information and so on to assist the reviewer mind produced visualize and spatialize information. The smart handheld device becoming more and more popular in recent years, it has matured software and hardware communications technology. By using the hardware of smart handheld device to support the need of investigating items in fire investigation into electronic check and form filling.This research uses two-tier system architecture, respectively for the client and server. The server side uses both WAMP as the operating system, and MySQL as the database engine. The client side is used with PHP technology. Based on the studying illustration result, this system not only provides the data storage of inspection results, but also can be used for the relevant units in the future review.
