i think steel frame buildings are resistant, it is the composite action of the steel frame and otherments that are together with the frame that help make them support; is that right? >> yes. that includes the walls, the floor diaphragms. but the fire was really bad. this is what they were trying to do here is a fire break here. in addition to the heroic fire break that stopped the fire on van ness. >> dynamited around here. not just earthquake or fire damage, it was dynamite damage. >> one of the interesting stories is the amount of dynamiting they were doing in some cases was so excessive it was damaging buildings that survived the earthquake and fire because they were blowing up the building 2 blocks away. the classic story is on the post office. it survived the earthquake and fire fine, but didn't survive the dynamiting of the next-door neighbor's building. >> they threw up flaming shards. and set the buildings alight. >> for an old steel frame, you see the beam and column and you can see the frame is shown there. on the side of the building, it is more solid with brick. the older

and the steel could be reused? >> it is hard to say at what point we would exercise the cancel option, but the order would include purchase of raw steel and the fabrication and delivery. if at that point but project does not go forward, then we would be meeting to employ this deal elsewhere in the portfolio. if at some point the project receives approval sooner, we could exercise our determination rights at any other point in the delivery stream. >> is there a point where it would be harder to use this field? >> it is specialized for this building, not for the site. you come put it somewhere else. it is a building that will look like the building we envision for pure 27. is that correct? >> yes. could be. >> could be, is that what you said? [laughter] what i am getting at is we would be able to use whatever funds are expended, that still could be utilized elsewhere and not be out significant funds regardless of the point in time within which we had to terminate. >> correct. there are many materials we do inventory.

with steel. she has created a sculpture made from steel columns salvaged from ground zero. the force of the collapse left the steel pieces, many longer than ten meters, twisted and broken. over 100,000 tons of steel were retrieved from the site. after a decade, pieces were distributed, free of charge, to many locations in the u.s. and around the world, to build memorials. a london group commissioned miya to create the sculpture. at first she felt the work would be daunting. the daughter of an american father and a japanese mother, she was inspired by the fact that a lot of the steel in the twin towers came from japan. a u.s. government report says almost half the steel was produced by major japanese producers at the time. >> some of it is from japan, it's even more meaningful to myself, as a japanese and american heritage. >> reporter: this steel from ground zero was coated by rust. but after sanding and polishing it, miya made the material reflect like a mirror. miya had seen to it that no one c

at good win steel. if you look at the entire eastern span, we have most of the piles and the foundations, these massive footing boxes that the bridge sits in come from exotic places like vallejo, california, corpus christi, texas, and up in oregon and washington. so there are a number of different place that is contribute to providing different structural elements. if you are looking at steel in particular, there is more domestic steel in the entire eastern span than any other foreign steel component. if you look at the final bridge, a little over 75% of the steel for the eastern span is fabricated in some u.s. mill. >> is there some updated total for the price tag for this project? is it still $6 billion for the price tag? >> it is about that, $6.3. the toll bridge oversight committee, which consists, caltrans and others, and they put out reports that says how we are doing financialally. along with that, there is a $900 million contingency. that is all downloadable from the bay bridge site? >> are you

>> the brand-new glass and steel building. when we build brand-new high rise buildings they're required to meet the minimum standard of the building code. the building code is a minimum standard document. can you choose to build beyond it. few people choose to build buildings that are immediately occupiable after an earthquake. most build buildings that won't collapse, which is what the building standard is. they won't collapse and they can be repair side whed

steel cable, steel or chicken wire mesh that the workers work on. we have wooden platforms on top of the mesh. you see this guy struggling a little bit to get in place. these guys had to do some different things than we had to do. but again you can see there the cat walk creates the geometry of the bridge. in the 1930's when those came out that is when bay area residents saw what the west bands looked like. that is what you are seeing right now. in the past few weeks away put our cat walk in place. you see a couple of film images of what you will see on site as they connect to the top of the tower. this is our back expand, the short expand that goes toward the island. also online we have a couple of quick methods of i think this is some of the electrical work that was done to put the lighting system in place as we get ready to place the main cable. here is a shot for scale that you can see. you see one person working there. the lights are the exact same fixtures that were used on the memorial bridge in 2002. american bridge procured them and is usin

it survived a fire as most steel framed buildings -- i'm sorry. survived the earthquake as most steel-framed buildings did. here is the chronicle building. it also survived the earthquake. the chronicle building is made up of two buildings in front. at the time of the '06 earthquake they were building the rear annex, which was the tallest building west of the mississippi. this building survived until the fire came. the fire did a lot of damage here. there is the examiner building. it also survived the earthquake, and the fire came. >> really interestingly, steel-framed buildings were a newish thing in the turn of the century. how many do we have in the city? >> from that vintage, that are actually still here, we probably have 30 or 40. but what was interesting is, the robeling steel institute sent a team out here. there is a document where they went through the buildings. all the buildings they reported on went through the earthquake just fine. >> one didn't. the williams building. >> interestingly enough, the williams building was not in the book

now's a good time to purchase steel. prices are low and the market indicates that prices will rise over the next six months. in order to include the less we will include an option to terminate this purchase order, which means that the project is disapproved, we could cancel the installation and perhaps the fabrication. furthermore, we may continue to pursue this purchase because the lower cost steel may be reused, either with port projects are other projects. if we were to delay this package until march 1, we would encourage delays, obviously, but also seven months of cost escalations, which we anticipate to be about $150,000. just to summarize, we can move forward with the release of $9.4 million and continue a reserve of $8 million. supervisor chu: thank you for that information. i definitely would feel more comfortable leaving on reserve that portion, so i would be comfortable moving forward with the 94 $4 million but not the $8.4 million as the detailed. given that we had actually put this reserve on budget and finan

it would be pouring it probably on a steel kind of thing. but at this point, the process changed largely during -- after world war ii. set up rebuilt belgium, rebuilt france, rebuilt -- so before all our glass was domestic and after world war ii it became foreign. they had all the new factories and we had the old ones. so they set up a product, and they would pour it and polish it automatically, so it was perfectly flat. and that was the origin of the polished plate. then, subsequently a process came up called float glass. and that was just revolutionized the industry because they poured glass out on a bed of hot tin, voluntary-in tin. why this -- vol tin tin. how they came up with that -- they just poured it on the bed and it was self-leveling and they made it so fast, cooled it down -- i mean you go to the factory in stockton and it's just like making cellophane or whatever. this comes in, comes out, bam. and it's now, you know, inexpensive and quick. and so the word -- technically it's not polished but it's just plate. it works. and so th
