Does the 1.9 mile Klystron Gallery have to account for the curvature of the earth during construction?

Aside from walls (e.g. the Great Wall of China), the Klystron Gallery is listed as the longest man-made structure. Given its length, are there special engineering considerations that needed to be taken to deal with the curvature of the earth, or is the curvature not a significant factor at 1.9 miles?

The main accelerator is a linear beam projector buried 30ft under ground which is straight as a laser beam. The building above it is probably a series of connected, traditionally built facilities which conform to the ground. If they didn't take into account the curvature the buildings at the ends would have an inclined floor.
