>> welcome to culture wire. we will look at the latest and greatest public art project. recently, the airport unveiled the new state of the art terminal. let's take a look. the new terminal service and american airlines and virgin america was designed by a world- renowned architecture's firm. originally built in 1954, the building underwent massive renovation to become the first registered terminal and one of the must modern and sustainable

terminals and the united states. the public art program continues its 30-year legacy of integrating art into the airport environment with the addition of five new commissions that are as bold and dynamic as the new building. >> this project was completed in record time, and we were able to integrate the artist's early enough in the process that they could work with the architect said that the work that is completed is the work that really helps complement and instill the space as opposed to being tucked away in a corner. >> be experience begins with the glass facades that was designed with over 120 laminated glass panels. it captures the experience of being under or over clouds when flying in a plane.

depending on the distance or point of view, it can appear clear for more abstract and atmospheric. the subtle colors change gradually depending on the light and the time of day. >> i wanted to create an art work that looks over time as well as working on in the first glance. the first time you come here, you may not see a. but you may be able to see one side over the other. it features a couple of suspended sculptures. each was created out of a series of flat plains run parallel to each other and constructed of steel tubing. >> it is made up of these strata. as the light starts to shift, there is a real sense that there is a dynamism.

>> it gives the illusion that this cultures might be fragments of a larger, mysterious mass. >> the environmental artwork livens it with color, light, and the movement. three large woven soldiers are suspended. these are activated by custom air flow program. >> i channeled air flow into each of these forms that makes it move ever so slightly. and it is beating like a heart. if-0 when as of the forces of nature moving around us every second. >> shadow patterns reflect the shapes of the hanging sculptures. the new terminal also features a

children's play areas. both of the market the exploratory n.y. -- exploratorium. the offer travelers of all ages a playful oasis. using high quality plywood, they created henches shaped like a bird wings that double as musical instruments. serving as a backdrop is a mural featuring images of local birds and san francisco's famous skyline. >> in the line between that is so natural, you can see birds and be in complete wilderness. i really like that about this. you could maybe get a little snapshot of what they are

expecting. >> it is an interactive, keck sculpture that is interacted with by the visitor. >> they are a lot about and they fall down the belt. it moves the belt up, and if you turn that faster, the butterflies fall in the move of words. >> the art reflect the commission's commitment to acquiring the best work from the bay area and beyond. in addition to the five new commissions, 20 artworks that were already in the airport collection were reinstalled. some of which were historically cited in the terminal. it includes major sculptures by the international artists. as a collection, these art works tell the story of the vibrant

arts scene in the early 1960's through the mid-1980s's. the illustrate san francisco's cultural center and a place of innovation that is recognized and the love throughout the world. one of the highlights is a series of three left tapestries. they are on view after being in storage for 20 years. these tapestries representing various gardens. from his years of living in san francisco. hydrangeas, chrysanthemums, and whilst dahlias in rich, deep shades as they make their way to the baggage area. they can access behind-the- scenes information and interviews with the artist through an audio to work. it features archival audio as

well as interviews with living artists. he can be accessed on site by dialing the telephone numbers located near the artwork or by visiting the commission's web site. the public art speaks volumes of san francisco as a world-class city with world-class art and culture. for more information, visit >> i work with the department of environment and we are recycling oil. thank you. we can go into a refinery and we can use it again. they do oil changes and sell it

anyway, so now they know when a ticket to a. hal>> to you have something you want to get rid of? >> why throw it away when you can reuse it? >> it can be filtered out and used for other products. >> [speaking spanish] >> it is going to be a good thing for us to take used motor oil from customers. we have a 75-gallon tank that we used and we have someone take it

from here to recycle. >> so far, we have 35 people. we have collected 78 gallons, if not more. these are other locations that you can go. it is absolutely free. you just need to have the location open. you are set to go.

>> welcome to the department of building inspection brown bag lunch. you are always invited to join us on the third thursday. today, we have a special program about san francisco's neighborhoods geology. we have frank, the geotechnical engineer who will walk us through a lot of this. we also have an architect who knows a lot about the history of

the city. he keeps his eyes open and has a lot of information to share. we also have the chief building inspector. we are going to go through this by having frank give us a brief overview of the geology of sentences go. then we're going to look at a series of slides around the city. and see how the geology of the city affects the environment. their special problems and issues that arise we will try to answer questions as we go, particularly related to how the environment release to the underlying geology of the city. those are questions that rarely get asked. this is a chance for you to join us and ask your questions as well. welcome, frank. i see that you brought a big aerial photograph with overly

geology. >> it is a big google map with overly geology. the different colors depict the different formations or deposits beneath san francisco. san francisco is a young environment. it is a relatively young environment. the basement rock beneath san francisco is known as the franciscan complex or formation. it is throughout the city, most notably twin peaks, edge hill, telegraph hill. every once in awhile, you hear about those who make the news with a rock fall or landslide. usually occur in the telegraph

and twin peaks. . above the rock are the soil deposits. the most common is dune sand. it is nothing but rocks that has been worn down from the sierras and deposited along the beaches. the wind blew that dune sand over most of the city. it is this mustard color. on the avenues, it is very thick. it can be up to 400 feet thick. as you moved south across slope boulevard, that is the tolar foundation. it was named after the first to score every in -- after the

first discovery in the cemetery. the man was out there and noticed this material was unique. he started mapping it. he traced it all the way up to slope. the dune sand generally has the consistency of sugar. it is fine grained sand. it is usually loose. it is poorly graded. the colma foundation can be the same stand but it is denser. it may have to play in it. it is much stronger. it is an excellent supporting material. it is up to 10,000 years old on the dunes and. the colma is 40,000 to 60,000 years old. in some areas, it may be as old as 130,000 years. as you move across the city and get to the border, you get to

ground that was originally under water. that sits on top of bay mud. wea is ak ve-- that is a very y with the consistency of jello that has been left in the refrigerator for several days. the others are residuals soil. they are either a product of the weathering of the underlying law. peluvium is soil that has been deposited by gravity. san francisco, dune sand, colma, and the others. very simple.

because san francisco is so young. -- because san francisco is so young, it is riddled by faults. i have a map that shows the faults across the bay area and san francisco. the granddaddy of all of these is the san andreas fault. it is the longest. it can generate the greatest earthquakes. >> it is just south of san francisco. it goes offshore down here. >> from my house to the fault is about 3 miles on average. >> the closest area in san francisco to the fault is this area here in the southwest part of the city. people said that the closer you are, there are conditions that exacerbate issues. >> the fault's effect on

development depends on the fault type and soil component. the san andreas is the main fault. there is the hayward fault. the difference between the two is that the san andreas is predominantly offshore. the hayward fault actually crosses beneath populated areas and poses a larger threat. as we speak, there is a 67% probability of a major earthquake on one of these faults in the next 30 years. it is of major -- high probability. it is a magnitude 6.5. the 1906 was 7.9. the 1957 earthquake was 5.7 on

the san andreas. the loma prieta was 7.1. it was so far with it we got a little effects of it. that is the overview of the geology. >> i would like to setup a wonderful old chart of san francisco from the 1850's and 1860's. let's look at this northeast corner of the city. it is really interesting. i am sure that frank has a lot to say about it. the thing i find absolutely surprising about this is that there is this large area called mission bay. out in the middle of the bay is mission rock. many of you have been to mission rock resort. this is part of the shore line now. look how far off shore it was in the 1850's.

this has all been filled. many of these areas are now filled. let's talk about that. >> this is montgomery street. e have thembaradero -- now we have the embarcadero and marina. this map is the infamous lipofaction map. the green areas are the areas that will have potential lip ofaction. that is a loss of strength of material when it is subjected to vibration. it can occur in sand and silt.

those have to be saturated or below the ground water level. you can almost type dismount tie t --tie this map -- this area right here is the same as this one. it is all silt and will liquefy. the marina is in this area here. you can correlate the advancement of the shoreline of san francisco with the potential for liquefaction. >> it is a perfect example. it is all sold and liquefaction. >> treasure island is unique. it was originally developed to be the location of the world fair with the understanding that once it was finished, that would become the location of san

francisco international airport. it is 11,000 feet long. in those days, the thought that was more than enough to land any conceivable airplane. they thought it was ideal. they said that we have all kinds of sand out in the bay from the sacramento river. we will take the stand out of the bay and create this island. the sand is loose and below the water. it liquefied in 1957. it liquefied in 1989 during the loma prieta. it was similar to what happened in the marina. >> as they move along and developed treasure island, the developer also has to provide stabilization programs. >> the sand has to be strengthened so that it will not liquefy. the buildings have to gain

support below the sand in more confident material. >> we were talking about the waterfront. here's the very building. here is the intersection of the water and the land. the area where the ferry building is now was what? >> it was silt. to create the embarcadero, they had all of this exposed rock. they decided to mine telegraph hill for the rock and build a levee and bill in behind the levee. they blasted the rock. it was illegal but they did it anyway. they took the rock and built a rock dike all along here.

beneath the fill the latem are of this mud with the consistency of jello. that layer may be as thick as 110 feet. >> is bad dyke founded on the mud -- is the dike founded on the mud? >> it is. 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 recently provided a small boat docking on the waterfront. there are very few places where you can stop on the
