http://www.safetyculture.io/case-studies/level-10-construction Working on a 54-story high rise building in the middle of downtown San Francisco comes with its unique challenges. One million people commute into the city on a daily basis. Level 10 Construction needed to ensure the building could resist earthquakes of an 8.0+ magnitude and be occupiable the very next day. SafetyCulture iAuditor was number one tool of choice to ensure not only the safety of workers, but the one million commuters surrounding the site each day. They performed 2.5 million man hours with no loss-time injury.
