The Denver Performing Arts Complex (DPAC) Parking Garage is an eight-story structure with capacity for 1,700 vehicles. 360 Engineering provided engineering services for replacing the storm drain piping, as well as consulting related to temporary relocation and protection of the facility’s mechanical and plumbing systems. The team performed multiple site visits to observe existing conditions and, based on detailed field notes and photos, prepared construction documents for replacing area drains, roof drains, and associated piping.
