National Gallery of Art
The east wing of the National Gallery of Art was designed by I.M. Pei and built from 1974-1978. This post-tension concrete structure is clad with marble creating dramatic angles and a triangular planning grid. BCA was hired to perform a materials investigation of the marble cladding to determine the cause of moisture infiltration and movement throughout the building. BCA surveyed the exterior with the aid of a boom lift for up-close inspection.
