Underground parking garage layout for the G1 level of a multi-story structure. This plan features an irregular geometric boundary with coordinated vehicular circulation paths, parking stalls, and structural columns positioned along grid lines. The layout includes multiple access points with entrance/exit ramps, designated traffic flow directions, and integrated service areas. The design incorporates strategically positioned structural elements to support upper floors while maximizing parking capacity. A coordinate reference system is visible in the drawing, providing precise positioning for construction alignment. The asymmetrical floor plan adapts to site constraints while maintaining functional circulation throughout the parking level.
