Visualizing 200 Years of History Under Capitol Hill
By Elliot Carter
Thousands of federal employees, elected officials, and visitors walk across the Capitol Grounds every day. This 250 acre complex includes an underground visitor center, three library buildings, seven office buildings, a dedicated power plant and police headquarters, three Metro stations and one massive train station. The Capitol grounds look like a big park when viewed from the sidewalk. But when I walk around The Hill I try to imagine the underground world that can't be seen.
Here are some screenshots from a 3d model I have been working on in Sketchup, an architectural rendering program. You can see how the waves of construction expanded and connected the buildings on The Hill.
