so you nail the plywood to the sill. and you nail the plywood to every stud. that's simple enough; right . at the top of the wall, you have th a double top plate. you should run your plywood all the way up and nail it to this upper top plate. that's ideal. all right. with no gaps no horizontal gaps. all the way from the sill up to the top. >> page 7 shows that clearly. it gives you a post, preretrofit condition and post retrofit condition with the plywood where they nail it up to the underside of the floor joift. >> if you are lucky enough to have a house where your garage level, floor level is higher, quite tall, most likely one sheet of plywood will not reach and you need to -- you will have a horizontal joint between a pliwood sheet you need to put a block in between the studs in order to nail the plywood sheets together to the blocking. all right. now look at this. this is the top of the wall. all right. there's at double top lay. it's hard to see, i'm sorry but this is the floor sheeting diagonal sheeting the floor joi st and this is a piece of block like

or basement walls to add plywood in shorter segments. longer is better, of course. you don't want to go over board and for example, cover one entire wall with plywood and leave the others bear. you are making it worse. the best thing to do is to distribute the installation of plywood as evenly as possible around the perimeter walls much the simpson book shows a picture of that. >> page 13 and 14. >> those typical for most san francisco houses especially be

there's no plywood there.hat's the wall that really needs to be stiffnd up because that's the short dimension of the house. >> in '89 and most earthquakes in san francisco, buildings don't fall forward. they don't go towards the street. they lien over or rack , so wha you really want to do is anchor bolt all the way around the perimeter of the building, you may put plywood in the side walls but it's the front and back that is critical. because the building wants to, it's usually narrow or tall and it wants to rollover. you want to plywood the front and back if you can and maybe add a footing in the middle. it's amazing the minimal amount of strengthing you can do is enough to give a building an excuse to stand up. >> we've looked -- i have and i know pat has looked at hundreds maybe thousands of earthquake damaged buildings. the smallest investment in structural improvement will prevent buildings from collapse >> it's not just the damage. you have to live somewhere else while in is going on. all the things you

it was under plywood and carpeting for about 30 years. this was amazingly preserved underneath all of that when it pulled up. >> how to the ventilate this? are these operable? h[ph>> they are not. we have a cool air intake from the bay. because of the atrium, it would be nearly impossible for any air conditioning, so we have cool air intake on the bayside. that cools the building down. when i first artwork in here, i was fascinated with all the arches, the repetitive arches. the original architect used it as a symbol of the talks in rome, a symbol of how important the water and the waterways are to us city. -- to the city. it looks like an aqueduct structure. >> what are the uses of this floor and above? >> we have about 10 it office spaces, private businesses, law firm, financial management, lobbying firms. there are all local businesses. -- they are all local businesses, very supportive of the marketplace. >> i know that some part of this building, the water goes underneath, the bay water is under there? >> yes. >> is it under the whole

it's a given on wood homes that adding plywood is an automatic. >> it stiffness the building up every. here's a guyana doing tile work in the garage there. you have a contractor, you have to open the wall up. do a little earthquake work,ái every project you do. here we have a building for lease, one of the issues we see commonly, i get a lot of questions how safe is my building. is it safe? no one knows when they lease an apartment or home or whatever they're leasing, how safe it is ask your landlord or homeowner. ask your engineer, how safe is my bill something they assume i the building department let's i be occupied it has to be safe. i want to point out a few other things we have on the table tha you should be taking a look at. there's this wonderful guide book called putting down roots in earthquake country and it wa publish fwid united states geological survey. it was in the paper the other day and it looks like an ad and it was in with a lot of ads, so people tossed them. i would pick one of these up. we have a lot of information here in the building department you need any hel

if we close out and we put some plywood, we know it will have graffiti on it. we know that people will not respect this space. they are opening up their businesses, their buildings and they are saying, let's invite young artists in and let's have these artists go at it in great very visually stunning storefronts. >> this is a pilot project that was started by the mayor as part of his local stimulus plan in partnership with the mayor's office of economic and work- force development. we carried this space in the mission. we were hired to curate this project. we have been the ones that have been handling all of the day to day working with the artists helping to secure their locations. >> we are doing projects in central market, the tenderloin, the bayview, and the 24th street corridor. >> we are looking at the history of the neighborhood and their ability to translate a the kind of things that go on on a day- to-day basis. >> we have over 200 applicants. it was wonderful to see how many people participated. these people clearly understand the neighborhood. >> this

a broken piece of plywood was also left. weber's told the bell likely had help. it weighed up to 600 pounds and was in plain view from the street accessible only from stairs or wheelchair ramp and was priceless dating back to 1901 with the original church was built. the st. michaels 800 member congregation is parade someone will help find that piece of history. time is important because police say there's a chance it might be destroyed. >> the bell was made of bronze, that is my understanding and it is one of our concerns that it was taken and sold as scrap metal. >> reporter: today at the scrap metals shop many notices coming about stolen items and she says a 600-pound bronze bell would garner more than $900. >> they tend to take it some place to get it chopped up and get rid of, the to not try to sell it. >> reporter: this is not the only historic bell stolen. we've learned today that there was another bell stolen that dates back to 1808 stolen but the botanical gardens in san francisco on march 10th. in either of these cases the thieves could be facing felony

and you are also going to state that you are installing plywood sheathing at the -- at the bottom level of the building. on that permit will be -- if you come in on a monday morning you will leave on the monday morning with your building permit and start work any time. as long as you fill out the application completely. >> as i said, the general guidelines and tips for the voluntary strengtheng are adding bolts one size does not fit all. all buildings are different. i refer to the sunset richmond houses if you have a victorian there could be a crawl space and that space may be harder to do the work. i'm not saying you shouldn't do it but it may be a different approach on how to get access to the area. i want to talk about installing the anchor boltses. i have done quite a few of them in san francisco. if you are handing with tools or construction equipment this is something you could accomplish. my estimate for installing an anchor bolt is 30-75 a bolt. so the it's better, the easiest place to do the work is in that typical open garage basement where the walls where there is no sheet ro

i put very thick plywood on the roof. >> how thick to support a story falling?(laughter). >> thanks for helping me out. (laughter). >> the rialto building. this is interesting building that survived the '06 quake. >> it did. in some of the reports it is reported it had undergone earthquake damage. if you look more into the building. in the 1907, they basically explain the damage is dynamiting. this is a building they tried dynamite apart to create a fire break, and the building wouldn't do it. it said no because it is a steel framed building. and as a class steel frame buildings are very resistant to both earthquakes and dynamite. >> am i right? i think steel frame buildings are resistant, it is the composite action of the steel frame and other elements 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 aroun

his doctor desperately appealed to people across the area to donate they were frantically shipping plywood into the hospital, some even arrived in the hospital. >> in the hospital it was dramatic, we had three runners running between the operating room and the blood bank. there was one person at any one time gathering bags, one waiting for more product, a third person in the door coming to collect another round of products. >> reporter: many people across the bay area he'ded the doctor's call and donated blood. there is no doubt that that went a long way to helping this fehr and perhaps many other patients, and dana, the other thing here i want to tell you about is i ran in the police chief of the fremont police. i said how is the officer doing and will he be able to serve again. and what he told me was it's a long way from knowing that, right now they are worried about, you know, recuperation and they have to cross another bridge, will he be an officers again. that's a tough conversation he'll have with his fam lee. >> a long road, we wish him the best. joe vasquez in oakland, thank you.

people and plywood poured in from all over. there were new schools and talk of new beginnings.evees and flood walls, but no less distrust of the corps that built them. some neighborhood bounced back, yet some still languish. if it was an equal opportunity storm, some think the recovery has been less so. still, there's a spirit down here that did not exist before katrina symbolized by the once-hapless states winning the super bowl. they say that which doesn't kill you makes you stronger. folks who survived katrina are proud they have weathered the test of a lifetime. that's the "cbs evening news." special coverage of katrina five years later continues tomorrow on the saturday the "early show." for katie couric and erica hill, i'm harry smith in new orleans. i'll see you sunday morning. good night. captioning sponsored by cbs captioned by media access group at wgbh access.wgbh.org [ son ] i'm a good son. dependable. i call my mom every week. i even bought her a computer with my new citi forward card. then one day... have you seen this? she "friended" me. there's a whole album.
