Fab 4 &5, Beijing Semiconductor Manufacturing Corp.
Following the 8 inch Wafer Fab built by our client, this project is a 12 inch Wafer Fab and the first one of its kind in China. It consists of two Wafer Fabs and a Support Building, a Center Utility Plant, Administration Building and other auxiliary facilities.
The Administration Building is situated at the front of the building group, connected to the various factory buildings behind by covered arcade. A curved and bent facade expresses the flowing quality of the wafer production while mitigating the oppressive effect of a massive building. The Administration Building contains dining hall for 3,000, a 1,200 seat auditorium, and a four story high glazed winter garden to house staff lounge and recreation room which when lit at night, shines as a giant landmark.
To respond to Beijing's 40 degree Celsius summer temperature and minus 15 degree with sand storm in the winter, the exterior walls are composed of insulated metal and dual- layered glazing, with special insulation at the main Fabs for energy preservation. A special air circulation system is designed to withstand the attack of sandstorm.
