Financier, philanthropist, and art collector Eli Broad is suing a German sub-contractor that was hired to create a unique, latticed facade for his forthcoming flagship museum. The Broad Collection, or The Broad for short, was slated to open in downtown Los Angeles by the end of 2014, but officials announced in February that the date had been pushed to 2015 due to construction delays. The $140-million institution will house approximately 2,000 contemporary artworks, including pieces by Jeff Koons, Takashi Murakami, Cindy Sherman, Andreas Gursky, and Mark Grotjahn, from the collection of Broad and his wife, Edythe.

The lawsuit, filed on Friday, May 30 in Los Angeles Superior Court, accuses Seele Inc., an architectural engineering and fabrication firm based near Munich, of numerous infractions, including breach of contract, fraud, deceit, and unfair competition. Seele was brought on by Broad and the museum’s general contractor Matt Construction in late 2011 to create the institution’s “veil” -- a honeycomb-esque facade that wraps around the building’s exterior and is expected to be one of The Broad’s most distinctive features. Seele has helmed numerous projects in the U.S., including creating striking exteriors for the Seattle Central Library and the New York Times’s Manhattan headquarters.
