The complex challenge that Posillico faced was time. This project is a 55 acre landfill that needs to be closed in less than 1 year.

The solution by using multiple crews and rotating shifts has increased productivity. Also Posillico's GPS guided machinery can level the ground faster and more accurate than in the past.
