ENR interviewed Robert Mitroff, chief planning and development officer with the Bay Area Rapid Transit Authority (BART) for the February 2017 cover story on transit construction trends. These are condensed excerpts from the interview.

For us, monies from the counties are good, because it's money—but often it is money that is purely serving localized needs. It can be difficult to get [everyone] to focus on system-wide needs like maintenance facilities and train cars. That’s why we need the federal and state program.
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.
