The project included the oxygen supplying system, the ventilation and air changing system measure of tunnel environment, monitoring and comprehensive treatment on airborne dust and toxic and harmful gases, hygiene intervention with builders in Fenghuoshan Tunnel construction. In the worst sector of the whole Qinghai-Tibet Railway line, we acquired a good achievement of the lowest incidence rate of altitude disease. Hence the Fenghuoshan Tunnel was joined up in advance, which set up a new record for frozen soil tunnel construction at high altitudes. The application of health care measure for tunnel construction promised rapid results.展开更多

Most of international sustainability rating systems consider IEQ as a key perspective for developing sustainable buildings. Educational buildings include large number of people which increase the need to provide appropriate IEQ. Accordingly, there is a critical need to frequently assess of IEQ in this type of buildings in order to maintain the satisfactory level of IEQ. This paper aims to develop a framework for assessing and improving the IEQ of educational buildings in Saudi Arabia through measuring the IEQ parameters and integrating these results with Building Information Modeling （BIM）. The key IEQ parameters considered in this study include thermal comfort, indoor air quality and visual comfort. These parameters have been measured by comfort-sense system, indoor air quality meter and light meter respectively. The measured data are integrated with BIM model in order to track the IEQ problems, and to develop IEQ history over time. By using the proposed framework, the IEQ can be tracked and improved. The IEQ assessment framework has been implemented on educational building in Saudi Arabia as a case study to validate the process and perform the necessary modifications and improvements.展开更多
