In an effort to prevent train accidents on a new $2.3-billion, 10-mile-long extension line in San Francisco, the Berryessa-Valley Transportation Authority/Bay Area Rapid Transit (BART) team is installing a railroad intrusion-detection system (RIDS) that uses warning devices originally developed for protecting shipping ports from break-ins.
Social media, mobile devices, apps and drones are finding new roles helping stakeholders—such as construction companies and their personnel and jobsites—who have assets at risk when they confront shifting disasters, such as hurricanes and wildfires.
Unmanned Aerial Systems pilots are flying close to landslide-prone terrain to collect higher-resolution elevation data than traditional aerial imagery can deliver, and they’re doing missions in scant hours—putting near real-time monitoring of dangerous slopes within practical reach.
Geospatial Media and Communications, an India-based market research firm, released a market report on August 2 about the state of Geospatial and BIM use in the construction industry and linking it to the construction economy as a whole
Since Los Angeles joined San Francisco Bay Area cities last October in tightening seismic standards for non-ductile concrete buildings and multi-family, wood-frame structures with parking underneath (ENR 11/9/15 p. 16),

A new application turns hard-to-manage physical documentation into a searchable cloud and mobile-enabled database to save time spent searching for operational and achieved facility management documents.
To help remote communities and developing nations adopt sustainable energy infrastructure, Oregon State University researchers recently released an open-source, small-scale hydropower assessment modeling package.
Because it can moderate the damaging effects of earthquakes, base-isolation is a technique used primarily in seismically active regions. ENR takes a look at some of the largest applications of base-isolation technologies in the world.
