Architect Arthur Erickson created an instant identity piece for the city of Fresno with his new City Hall building. A. Zahner Company created the roof system. Due to the shear size of the building, the seams of a conventional standing seam roof would have disappeared. These seams that you see here are 6 inches wide and almost 6 inches tall.
In this view showing a portion of the back side of the building, the shadows make the seams more visible.
