What principles apply to entrance and ventilation shaft planning on the Taipei MRT? (Civil Works)
Station entrances provide the link between the station concourse and surrounding streets. They shall be clearly identifiable as an entrance to the MRT system and shall be well lit. They may also cater to transfer facilities, including bus transfer, passenger drop-off, and park-and-ride facilities. Entrances may be integrated into MRT-associated developments but consideration shall be given to the requirements for flood protection and fire compartmentalization. Entrances to underground stations may be combined with other MRT structures such as ventilation shafts, firefighters' access or refuse storage. Each entrance shall be designed to suit its location. Design shall blend with the urban landscape and incorporate plants and kiosks when appropriate. The environmental control system (ECS) of underground stations requires ventilation openings for air circulation. Three independent shafts are needed for the use of air exhaust, fresh air intake and draft relief. The shafts may be combined into one structure or separated into two or three structures, depending on site constraints and architectural requirements. The ventilation shafts may be independent or combined with other structures such as entrances or joint developments.
