probably the same size installers prefer to use solid. it's required by code in swimming pools, but this is an easier, when it's stranded, it's easier to use. this is probably the cable of choice in concrete. this is the classic wire and number four to be encased in concrete at the bottom of a footing to get a good ground. >> look at some of these things here. >> here is another cable. it's nonmetallic cable. it has four conductors in it like the other cable. it's a larger size. it's for a 100-amp meter. it has a white, black, and red of probably number four and number eight ground wire in it, nonmetallic cable. >> this is the big stuff now. >> this would be a theater to a panel board versus, how about this one here? this is a single conductor. the wire will go in a conduit for a commercial installation and would supply a 200-amp panel board. >> how big does it have to be for 400? >> two sets. or you can use something called 500 which is a conductor twice as big as this. >> hard to work with. >> you have the choices in installing. two set

first elevators were installed for moving materials in the 1860's. in the 1870's, the first passenger elevator was installed, and that allowed building heights to go up to about seven floors. starting in the 18 eighties, 1890's, the first electric elevators were installed. that allowed for buildings to go up even higher, even more than 10 floors, and those were the first elevators that became representative of what we consider modern elevators today. >> so the height of buildings is related to elevator technology. >> both of these technologies encourage architects to build taller buildings. engineering and materials science provided a higher quality of steel to build with, and having passenger elevators meant it was the necessary anymore to climb a long flight of stairs to get to the top of the building. the elevator made the upper floors of the building more attractive than they were before. >> here we were at the historic st. francis hotel, which was actually a representation of the evolution of elevators. can you tell us more about san francisco h

the advantage of these installations is that they install it for free. they maintain it for 25 years and we get the power in the school at exactly the same rate we would pay if it came across a wire from hetch hetchy, so it's sort of the universal win-win of going green. now, on the flip side we're also doing some of our own installations so we're trying both. we have just finished the first one that they did for us at el dorado and the puc subcontracted the work out to their solar provider commissioner. the project was done complete on time and on schedule with the group and in fact the grand opening of the installation, and i think commissioner wynns was due to be one of the keynote speakers happened to fall on the day of the connecticut tragedy and it was canceled so that is still to happen so i can't speak to the particulars commissioner. can i get you the information. i can tell you that first one was done over the summer. it went smoothly. the school is delighted and we're hoping to move forward. we think thurgood marshall that has a great flat roo

at&t is seeking your approval to install 12 panel antennas. under the city's wireless guidelines located at octavia and lombard. with the america's cup anticipated traffic in that area. we have experienced exceptional growth, upwards of --. one thing will learn about the super bowl, traffic surged 80 percent over last year. between 8-9 p.m. when the lights went out, our customers used 78 gigabytes of data inside the superdome equivalent to 234 social media messages or 10 days of streaming video. 73,000 voice calls made. it is clear that our world is changing. we have increased growth on our networks day in and day out. we are upgrading our network as you know everyday in the city and around our territory to account for those customer needs. we look for your support in approval of the site. i want to thank department staff and michelle for their time and energy spent on the site. thank you. >> commissioner wu: let's open up for public comment. ms. duffy? >>: my name is joy duffy, i lived in arena and -- area for over 50 ye in. arsi find that th

the wire will go in a conduit for a commercial installation and would supply a 200-amp panel board. >> how big does it have to be for 400? >> two sets. or you can use something called 500 which is a conductor twice as big as this. >> hard to work with. >> you have the choices in installing. two sets of these or one set of 500's. >> when somebody orders this grounding electrode, how much do they usually order? >> by national code, we need 20 feet. >> 20 feet has to be buried. >> in the rebar. we need 20 feet. so whatever we need longer, we can cut extra. >> so 20 feet plus what it takes to get. >> whatever they want to. >> cut us off a little bit. >> david, let's talk about energy efficiency. i know fluorescent lights and bulbs are a big issues right now. people are changing old-style fluorescent bulbs. what's the old one, the new one and the savings? >> the standard of the industry were t-12. this was a four-foot lamp. the 12 stands for and and it's about four or five times more efficient than the typical incandescent light bulb. in the energy to increase energy efficiency. they have

installed we want them installed properly to make sure they are not attached to the drywall. we have a advocate who had a suggest to get a portable commode railings and but they said someone should steal it and so it's something that needs to be securely put in place and is permanent and wouldn't get stolen and benefit best all people as well as seniors and as far as the telephone jacks we surely advocate for the lifeline system that california create but what is the point in advocating for such a system if you don't have functional telephone jacks for them to be using. so the program itself cannot be fully complemented. >> thank you. >> next speaker? >>> michaelline i'm with senator and disability actions these are not are not movies but the semi circular canals in your head that perceive position and is it's common with people as they get older i have been noticing with myself when you change your head position you get a feeling of vertigo because the impulses are not being processed correctly, this is a common situation with older people. why when is the most dangerous roo

after the conduit installation at these locations. that work is anticipated to begin in june 20 fourteenth after the paving work is completed. >> we had approved that earlier this year? >> that is correct, july, 2012. >> last year. >> yeah. the final request is from bart, for the 24sth st. pedestrian improvements. bart requested 200,000 in funds and -- as part of the larger 24 street pedestrian proven project. this project specifically will focus on sopwith plaza and includes installation of two cub ramps, public artwork, landscape improvements such as artistic fencing. bart's 24th street north -- project is a continuation. this project was from eight community-based plan -- prop k will be leveraging 2.1 million, bart anticipates construction of this project will begin in february 2013 and concluded the end of this calendar year. this request as required financially neutral amendment to the prop aa strategic improvement, five-year prioritization program to -- from fiscal year 2013-14 to 14-15. to enable bart to award and begin constru

installed test pads for concrete performance. so it's been run very cleanly, very efficiently and very safely and we have received very good reports. with a warded the primary construction work to shimmick. we have our structural steel package out to bid and initiated requests to determine cast note production capacity and awarded the specialty consultant contract to prepare the cast note to augment the super structure package and we have that package currently out to bid. we have completed the performance test program and started preparation of the bid package addendum. with responsibility to the transit center construction documents we completed the risk and vulnerability assessment update for the epentire program and completed the needs assessment for enhanced it and communication systems. in to 12 we awarded a number of contracts and additions to the ones i mentioned for personnel and material services, below grade structure and grounding systems. we completed five relocation trade packages which you have in front of you. and

i am wendy bean and i oppose the installation of the antennas. i live in a building that is less than 300 feet from the proposed site of the installation. there haven't been many studies done on the effects of -- potential effects of radiation from antennas and there has been some and the higher incidences of cancer rates and a lot of them were done with controlled groups of thousand to 1500 people within 300 to 400 meters of the e erection of towers which is three to four times the distance from where the proposed installation site is. interestingly enough on february 22, 2013 something called the buy initiative report was publishd and this is a study of 1800 new studies regarding the effects of radiation and they include abnormal gene transcription, toxicity and stress proteins, loss of dna repair capacity and human stem cells, reduction in free radical, toxicity in humans and animals and host of other issues, sperm function and effects on the fetus and off spring and cranial development animals exposed to cell phone radiation and during pregna

we do not install them. we can ensure that the venue install a sound limiter to a system. some limiters are only effective for what we call dj music or prerecorded and mixed on site. for a live band, though it would be great if they work, they do not. because of the nature of the sound equipment needed. there needs to be a soundboard with lots of lines in and out. a dj equipment is simple. one source in and one source out. for live band you could have as many as five, or 36. huge concerts like at at&t park. you could have as many as 150. on the dj board, the sound reaches a certain level and the equipment is not allowed to go beyond. it is like setting a dial. >>: mission commissioner borden. >> commissioner borden: you mentioned that permits go with the person. how does that work? if i own a business called borden and antonini, is it under my name or i can open up a new business and call it city hall ventures. my point is that if people on multiple businesses, is assigned to the person of the business name? if so people permit history on venues that these people own? how

it's quicker to install. >>: mmhm, quicker to install and you don't need a footing to put it on.an put it in the middle of the wall. just stick it right on there. >>dean: and so how does it go on? how does the installation differ from let's say installing regular thick 4" veneer stone. >>: well a thick 4" veneer, you start at the footing and you put mud down and you keep stacking it. this you don't need to stack it. you stick it. you put some mud on the back of the stone. and it just ... give it a little wiggle and it just sticks right to the wall. >>dean: and that's sitting on top of a mesh. >>:well, we've got the tar paper. and then this is our weep system which any water does get back there, it weeps down the tar paper. comes out the weep system. there's little holes under here so we want get to there. it comes out the holes and then we put our mesh on and we put a brown coat on and then the stone goes right on top of that. >>dean: okay. then what do you do once it sets up? how do you strike the joints and stuff? >>: well what i do is i grab my grout bag and i get some mud in

efficient projects over installing the sol ore or combining power spue in many of the cases, it would be a city project and the city would have the responsibility. and the answer we have also received from the l p i is that. that ultimately is a contractual detail that would have to be looked at as part of each individual project and so not to minimize it that we would have to have that contractual negotiations with every private property owner for the six-hundred solar sites that we are attaching to rooftops and the first time, a rooftop get a leak, that would be a concern because it will be one of the ways that a contractual obligation is tested as to who bears the responsibility of a roof leak for any of the 600 projects or 550 energy initiate projects whether then replacing light fixtures or widow energy improvements or the 300 combined heat and power facilities put in the basement or on top of the roof and so it's a very large contractual and project management challenge and that is one of the key operational relatives that is present in addition, to the fm risk where we have spe

, efficiency installations. most importantly behind the meter in customer's property and what that is about is -- it means it's after the meter that pg&e has on the house so what you're doing by doing small diverse local installations like that behind the meter you're avoiding a lot of cost of transmission and distribution that you would otherwise have to pay pg&e, and so that's the key to that model, and along with that you get the benefit that because you're installing a lot of small renewables and efficiencies installations you're creating a lot of jobs. right now the model that local power put forward looks like 3,000 a year, so it's very important that we keep on that model, but what we saw in the last week is that because of some of the critiques of that model we have been working on for a couple of years the staff has proposed going to a completely different model that is building large solar farms at a distance in front of the meter so they have go through pg&e transmission and distribution lines and the

it says one of them number nine, full upgrade at aps install one curb ramp. for me to understand it better is -- i couldn't find anything in the report. is there something else to look at to get more details? >> we have harvey quan can hear it. he's from the signal section from sfmta and happy to meet you with after or even better [inaudible] >> good morning commissioners. through the chair, commissioner yee i think you're referring to intersection number nine which is circular monterey and one of the challenging ones in the city. the scope of the project there is basically remove all of the signal and for the people coming from monterey and we going to install a curb ramp at one of the corners where it's missing and install the signals for the hearing impaired. >> does this -- one of the issues on that corner or on that intersection is that there is a median on monterey boulevard, and it's about 18 inches -- maybe 12 inches wide, so if one doesn't make it across and you're standing on a median and the traffic coming off the freeway they're going like 50 mile

look, they say that iran, they've installed even more advance centrifuges. what does this mean when they install more advanced equipment and how close can they be to potentially achieving a nuclear bomb? >> the enrichment hulls are huge, could hold up to 20,000 centrifuges. so they have a lot of empty space. the fact they're beginning to install the second generation centrifuges and perhaps more advanced equipment demonstrates that they're not inhibited in terms of expenditures on the nuclear program. the more reactor grade uranium they have, the easier it would be to create a large number of nuclear weapons quickly. many estimate they have enough low enriched you're uranium to t eight in a few weeks' time. if we legit myself -- >> eight nuclear weapons in a few weeks time says u.s. embassador john bolton. next sunday we'll talk about what they did or didn't achieve when they start talking on tuesday. >> thank you, eric. >> thank you. we want to tell you about new information on high profile cyber attacks that put our national security at risk and threatened

there are a few buildings in other major cities where they have installed wind turbines on the roof.rbines in buildings are effective. >> the discussion was do we do that or not? and the answer was, of course. if they're not perfect yet, they're building a building that will last 100 years. in 100 years someone is going to perfect wind efficient turbines. if these aren't right, we'll replace them. we have time to do that. >> the building that's two renewable energy generations. wind turbines located on the north facade. two different levels of photo volume takes. >> we have over 600 solar panels and three platforms on the building, and four integrated wind turbines. the wind turbines and the solar panels produce 7% of the building's energy. and we're reducing the use of energy here by 32% in the office building. >> the entire building is controlled by a complex computer system which monitors and adjusts air, heating and lights as well as indoor shades. >> the building is going to be a smart building. it's going to have all integrated features. so, it has a monitor on the roof that kn

and it is not a simple installation because we have databases that he has to install and customize on computers. in addition to that, he's responsible for creating databases, amending them, tweaking them for interfacing with our consultants such as the project that we have for online complaint filing. he's responsible for our server maintenance and the like. and, so, what i am proposing in staffing is an additional attorney and a new position which is an information systems business analyst assistant. i've talked about the occ's aging cars and how no matter what, they must be retired in 2015. and we use the cars in this case. our chief investigator rolls out to every officer involved shooting and, so, the chief investigator has a car 24/7. the rest of the investigators rely on one -- the other car, and that car is used or the investigators to go out in field and also for our support staff to make deliveries and pick up deliveries from the hall of justice. so, in conclusion, without a budget augmentation for staff and replacing two object -- obsolete cars t would affect the effectivene

the request is install up to [inaudible] on the roof top building and residential care facility. the facility -- because of the institutional nature is proposed on a location preference one site. staff is submitting the staff report staff has received two emails and a call oppose the project based on necessity, health concerns and design concerns. staff is proposing -- is recommending approval with conditions. >> project sponsor. >> good afternoon commissioners i am teddy [inaudible] and from at&t and i am here with the firm that conductedded radio frequency testing at this location and the third party review that was required. we are seeking your approval to install this facility consisted of nine panels that will be on the roof top of the building with transparent blinders to integrate this into the building. this is a preferred location and with the guidelines. the site contains a three story institutional building known as on lock day services that provides day time residential care. the site is necessary to coverage and capacity in the area which are served by the muni rail

we have the installation, the regional installation command and also partners with the operational foresite. we allow the operational foresight, we maintain those but then we coordinate, cooperate, with the operational foresight once the call comes in for support. so we're able to do that obviously through memorandum of understandings and we have agreements and our wing operating orders allow for the fact the operational control, at least under operational response, maintains with the operators. the third aircraft wing maintains operational control but we send our operatives out to be controlled by the civic sight. we're comfortable with that and that's matured a lot in the last couple years. >> talked a lot about command and control and agreements and moving resources. one other question that came up yesterday we were discussing yesterday is how do communications occur specifically with regard to when we start talking about air ops and moving air resources around, how do we ensure that we have that interoperatability that we discussed so much yesterday between the different components. >>
