Watch as a crew of 350 construction workers attempt to pour the top floor of a skyscraper in the middle of Manhattan, in less than 90 minutes. From the second water is added to the concrete mix, its already starting to harden and if it doesn`t make it from the plant to the site, reach the 60th floor, get poured and smoothed out all in 90 minutes, its useless and a day of work is lost. Can this crew get the concrete into Manhattan and up 700-feet in the air to get the job done before their 90-minute deadline dries up?
