Assembling any Turrell show is a complicated affair. Unlike a show of paintings and sculpture, every piece must be built on site, and even more than with most installation art, his work requires elaborate modifications to the museum itself. Windows must be blocked off or painted black to obscure the outside light; zigzagging hallways are constructed to isolate rooms; and each of the rooms has to be built according to Turrell’s meticulous designs, with hidden pockets to conceal light bulbs and strange protruding corners that confuse the eye. Even the drywall must be hung and finished with exacting precision, so that each corner, curve and planar surface is precise to 1/64th of an inch. It can take hundreds of man-hours to finish a single room; he was erecting 11 at Lacma.
