(3)Avoiding interference between MRT stations and neighboring households caused by exhaust gases – ventilation openings facing a six-meter area outside the stations.

2.The two goals of designated restricted building area are：

(1)Remind applicants that during the time that new buildings or renovations are constructed within the restricted building area, the mutual impact between buildings excavation and MRT facilities must be considered in order to avoid impacting the safety of MRT facilities and operations during excavations and, in turn, affecting the safety of public works.

(2)Assist architects who are constructing new buildings or remodeling buildings to fully understand potential construction risk factors during the planning and design phase in order to avoid the occurrence of occupational safety incidents during the construction of buildings and impacting the safety of MRT facilities and operations.
