Within the materials lies Schenkelberg’s remarkable talent for recapturing wonder. “Symptomatic Constant” is a massive work. It starts as rubble on the marble floor with plaster dust and shards of ceramic, resembling a shore of beach glass, then steadily the work grows up into the high space of the lobby’s ceiling with fabric draped to an old cast-iron heating register. Schenkelberg builds in layers with architectural salvage culled from the site itself as well as local thrifting. Her cultural archeology is distinctive in its details and restless as the whole of her ship-like installation.
