Exploratorium at the Piers:  A Joint Effort (Clip)
Running Time:
00:04:17
The Exploratorium’s new home has an ace up its sleeve for the next big earthquake—a single seismic joint, 300 feet long and two feet wide, will isolate the entire pier structure from the rest of San Francisco. Watch here as the bulkhead at Pier 15 is readied for the installation of the seismic joint.

Science in the City:  Rebuilding Doyle Drive (Clip)
Running Time:
00:03:50
At the southern end of the Golden Gate Bridge, a construction project to rebuild the elevated freeway ramp formerly known as Doyle Drive is underway. Senior bridge engineer John Walters tours us through some of the new seismic technologies being installed, including a seismic joint designed to handle several feet of longitudinal movement and a spherical bearing that allows for three-dimensional movement. Walters also points out a temporary structure built over the historic Presidio Pet Cemetery to protect the grave sites while providing a platform for the construction overhead.
