CONCRETE

These are examples of concrete on the GW Main Campus.  The railings, steps and sidewalk are all concrete.

This is the underside of a parking garage.  The concrete is supported by METAL steel beams.

I was shocked to see that the ceiling for the inner rooms of the National Gallery of Art are formed concrete.  It's widely used through out the building.

Concrete is a very diverse building material.  It can be used for walls, interior and exterior, floors and ceilings.  Here are examples of reinforced and formed concrete.
