Legendary Builders
The Engineering Department is where Builders work, and Free Building Speedup Time is what they give. Four Legendary Builders exist: Lucas, Noah, Carter and Anderson.
The game data lists two Free Building Speedup Time lines for them. The first is +32m at every star. The second starts at +0s and is the one stars improve: +6m, +12m, +18m, +25m and +31m.
