• Others – Safety, Failing Infrastructure
Potential Hurdles:
• Antiquated equipment & cost to replace
• New workflows and lack of training
• Difficulty embracing new technologies
• Local, State, Federal rules & regulations
• Computers needed to process the data
• Difficulty working with the data
• Technology moving at a rapid pace
• Others – Limited Access to Site, Real Time Alerting…
What lies ahead?
• Do we really know….
• Microsoft HoloLens & Trimble Collaboration
