Can artificial intelligence be develooped and perfected fast enough to help address the construction industry's skilled labor gaps and supply chain problems? Can robotics take over time-consuming tasks that are not a good use of workers' time?  These questions and more filled three days of attendee networking and construction technology presentations and discussions at ENR's FutureTech conference held May 4 through 6 in San Francisco. AI was again a hot topic among the more than 700 construction, architecture and engineering professionals who attended, but deep dives into robotics on construction sites, cloud-enabled workflows, 3D printing of structures and improved stakeholder relationships also generated new insights.   About "95% of AI pilots fail to deliver value," said Alan Espinoza in an opening keynote address.…
