TAISEI decided to deploy a paperless process with DWG files centralized in the cloud, using Microsoft OneDrive for Business. This enables real-time synchronization of DWG files between the design teams, who produce the DWG drawings using ARES Commander, and the construction workers, who view the drawings on iPads. But the next challenge was to deploy a Mobile CAD solution on more than 4,000 iPads to enable the construction workers to read, annotate, and eventually modify these drawings on site.
