15 untitled works in concrete, 1980-1984The fifteen concrete works by Donald Judd that run along the border of Chinati's property (Chinati Foundation, Marfa, TX) were the first works to be installed at the museum and were cast and assembled on the site over a four-year period, from 1980 through 1984. The individual units that comprise each work have the same measurements of 2.5 x 2.5 x 5 meters, and are made from concrete slabs that are each 25 centimeters thick. Funding for the project was provided by the DiaArt Foundation
