Cavar Construction was a New Orleans-based American construction company during the mid-20th century. It was founded by Jimmy Cavar, who developed extensive ties to the Marcano crime family and the Democratic political machine and used blackmail to force politicians to perform favors for his company. Cavar was notorious for having his enforcers beat up hippie protesters, take compromising photos of public figures for blackmail, and for his wide-ranging influence, and he was even under contract to build the new city hall during the late 1960s. In 1968, Lincoln Clay killed his major enforcers and even sabotaged his construction crane, damaging his power. Clay then confronted Cavar at the site of the new city hall construction site and forced him to work for him instead, and Cavar's operations were placed under the supervision of Clay's subordinate Vito Scaletta.
