Washington D.C.

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.
