Barry Bloom, owner of Assured Power in Milwaukee, Wis., knew something was wrong last year in the late stages of a renovation project to create a new Radisson hotel in nearby Menomonee Falls.

Bloom decided to take action after he found among the project documents a list of the other subcontractors. “I thought, it’s kind of strange I’ve never talked to these guys,” he says. “So I started calling them, one by one.”
