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.

Exploratorium at the Piers:  Jitterbugging: Pouring Concrete at the Piers (Clip)
Running Time:
00:01:51
Pouring concrete is an ongoing feature of construction at the Piers. This footage, captured in July 2011, shows the well-choreographed process involved, from pumping the concrete into rebar-latticed slabs via remote-controlled overhead boom, to vibrating the concrete to get rid of air pockets, to flattening the surface using 2x4s (“screed”) and rakes (“come-along tools”), to tamping in (“jitterbugging”) bits of sand and gravel, to the final smoothing and leveling of the finished surface. This pour created an extension to the southeast apron of Pier 15, adjacent to what will become the East Gallery.
