This Old House - Season 32 Episode 18

Master carpenter Norm Abram and host Kevin O'Connor stop by one of LA's major movie studios to find homeowner Kurt Albrecht at work in the animation division where it can take his team up to five years to make a feature film. Back in Silver Lake, things are moving a bit quicker, as Kevin finds the front of the house intact, but the back of the house is opened up wide from demolition—no walls or roof remain. Site supervisor Angel Leon shows Kevin the result of three weeks of work—a massive foundation form for the new addition that will meet LA's strict seismic code and "hillside ordinance" regulations. Two of the biggest challenges are getting five loads of concrete delivered up the narrow winding streets, and the 3000 psi mix that tends to set up quickly in the California sun. Up in Stockton, California, Norm visits a facility where they replicate real earthquakes with the help of a "shake table" to assist them in developing ways to protect buildings—and therefore people—from damage.
