when they dumped the rock into the bay mud, it was like dumping rock into jello. it went down into the mud so that they could build off of that. it then took the angle of repose. it is stable. san francisco came and built piers on piles over the top into the water. >> the piers are built up over the water. >> refusal is when you cannot advance the pile anymore. this is under the bay mud over there. they meet refusal. they gain support and bearing on top. saltwater attacks concrete. in the old days, they did not understand the effects of salt water, chloride on concrete and steel. a lot of these piles may have started out 24 inches in diameter. they may only be eight or 10 inches in diameter now. whatever steel was in there is long gone all along the waterfront. >> wonderful buildings. at the double dog and a beer. >> this is wonderful. it is right on the waterfront. it is due piles. >> that is the location of what is now the san francisco port authority? >> yeah, port offices. and there is a new office there and slip. this is one of the few places where they recent

rock week. 100 years later, the weak rock cannot stand there anymore and it fell. this slide is a long sansome street, where the city chose to protect sansome street and the cars, and they built this catchment wall. the sole purpose of this wall is to catch rocked that falls from private property. >> and every year or two, we get a call saying that rocks have fallen down the road and spilled over. this is the famous slide where we had a building at the top fall down this hill. this is the 22 street building. this was a watercolor done in 1945 by david mandel which -- by david mandelowiz. this building started gradually falling and sliding down. >> they had to replace the street right there. and in the process of jack hammering out the old st., they weakened the rocked. then the rockfall occurred. it undermined the building. once the building was undermined, it could no longer state occupied, and the decision was made to remove the building. as you recall, it made headlines. eventually, the building was removed and a new wall was built. the lot where 22 once sat is s

the rock under here is franciscan. it is sandstone. it is probably the hardest rock in san francisco at this location. we have just recently completed an investigation for the expansion of cathedral school, and they chose to go down 20 feet below the surface of the street, and it was incredibly hard. it was harder than the concrete that was placed as a foundation. the rock beneath the concrete was 10 times stronger than the concrete that is used to support the building. >> okay, moving to another part of the city, this is the eastern side. >> this is on army street? >> yes, this is army st., se. look at all that stuff. it is an active city. >> a lot of the old industrial, the american can co., goodman lumber. all that good stuff. >> wow. >> and this building is one of the examples of remaining 1906 earthquake damage. it has been repaired above, and that is where they repaired the damage. what did they found these buildings on, back in the early days? >> those days, remember i mentioned early on, it would use of redwood grillage and they
