San francisco is surrounded on three sides by water, the fire boat station is intergal to maritime rescue and preparedness, not only for San Francisco, but for all of the bay area. [sirens] fire station 35 was built in 1915. So it is over 100 years old. And helped it, were going to build fire boat station 35. So the finished Capital Planning committee, i think about three years ago, issued a guidance that all city facilities must exist on Sea Level Rise. The station 35, Construction Cost is approximately 30 million. And the schedule was complicated because of what you call a float. It is being fabricated in china, and will be brought to treasure island, where the building site efficient will be constructed on top of it, and then brought to pier 22 and a half for installation. Were looking at late 2020 for final completion of the fire boat float. The historic firehouse will remain on the embarcadero, and we will still respond out of the historic firehouse with our fire engine, and respond to medical calls and other incidences in the district. This totally has to incorporate between three to six feet of Sea Level Rise over the next 100 years. Thats what the citys guidance is requiring. It is built on the float, that can move up and down as the water level rises, and sits on four fixed guide piles. So if the seas go up, it can move up and down with that. It does have a full range of travel, from low tide to high tide of about 16 feet. So that allows for current tidal movements and sea lisle rises in the coming decades. The fire boat station float will also incorporate a ramp for ambulance deployment and access. The access ramp is rigidly connected to the land side, with more of a pivot or hinge connection, and then it is sliding over the top of the float. In that way the ramp can flex up and down like a hinge, and also allow for a slight few inches of lateral motion of the float. Both the access ramps, which there is two, and the utilitys only flexible connection connecting from the float to the back of the building. So electrical power, water, sewage, it all has flexible connection to the boat. High boat station number 35 will provide mooring for three fire boats and one rescue boat. Currently were staffed with Seven Members per day, but the Fire Department would like to establish a new dedicated marine unit that would be able to respond to multiple incidences. Looking into the future, we have not only at t park, where we have a lot of kayakers, but we have a lot of developments in the southeast side, including the stadium, and we want to have the ability to respond to any marine or maritime incident along these new developments. There are very few designs for people sleeping on the water. Were looking at cruiseships, which are larger structures, several times the size of harbor station 35, but theyre the only good reference point. We look to the cruiseship industry who has kind of an index for how much acceleration they were accommodate. It is very unique. I dont know that any other fire station built on the water is in the united states. The fire boat is a regionalesset tharegional assete used for water rescue, but we also do environmental cleanup. We have special rigging that we carry that will contain oil spills until an environmental unit can come out. This is a job for us, but it is also a way of life and a lifestyle. Were proud to serve our community. And were willing to help people in any way we can. Welcome. We are here doing our building San Francisco tour. Were going to have a very interesting tour of elevators in sanford cisco. We have all gotten into an elevator, the doors have closed, and it has carried us to our destination. Have you ever wondered how elevators were work . We check out the need outside the elevator using Current Technology and we learn about the latest destination elevated technology all here in San Francisco. We will also visit the machinery where all the behind thescenes gears control these incredible machines. We are very fortunate today to have an expert with those who is going to walk us are around elevators in San Francisco. Can you tell us about the history of elevators in San Francisco . The measure sure. The history of Elevator Technology evolves with the city. First elevators were installed for moving materials in the 1860s. In the 1870s, the first passenger elevator was installed, and that allowed building heights to go up to about seven floors. Starting in the 18 eighties, 1890s, 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 history here at the st. Francis . Sure. St. Francis demonstrates well the evolution of elevated technology. And substantially damaged the 1906 earthquake and rebuilt in 1907 or 1908, and extend it again in 1913. Then a new tower was added in 1932, so there is all sorts of Elevator Technology you can see at the st. Francis that very much represents the building history of San Francisco. I understand there is a really old elevator still operating here. That is right, the elevator installed in the 1913 expansion. We can go look at that. Lets go take a look. Here we are in a spectacular st. Francis lobby. Here is the clock. When people say meet me at the clock in the st. Francis. Lets look at that elevator. Ok, lets do it. Here we are in the elevator installed as part of the expansion, and this is the way it was originally installed about 100 years ago. It has a manual switch just like elevators did back then, and it runs on dc power. This was from a time before elevators ran on ac power. When did they switch . Decided to switch in the 1920s, so this elevator predicts that by about 19 years. The doors are also manual, so this elevator predates the use of Automatic Doors on elevators. Can we take a ride . Absolutely. Going down. How many troops do you think this elevator has taken in its lifetime . Millions. Yes, this one probably has. Certainly hundreds of thousands. Very smooth. It really does run smoothly. There we go. Take some serious operation. There we go. This is really beautiful. This is served by that old elevator we were just in. Built at the same time, also in 1913. What a gorgeous room. I think we should have a party here. That is a great idea. Lets look at the machine room for that old elevator. Ok, lets go. Here we are in the machine room with all these wonderful, old, a burly, industrialera equipment. Tell us what weve got here. This is really the beginning of a modern elevator. What we would describe as an overhead tractiongeared elevator. That type of elevator still exists. Even though this was made in 1913, elevators like this have continued to be manufactured up until the present day. So overhead means these cables attached to the top of the car. Correct, exactly right. Our hoist machine is located overhead, and this is a traction machine, so it is an evolution beyond the winding from elevator. This is the drive ship. This is the gear box, and this is original from 1913. It is a heavyduty design that we really do not see any more today. That is probably part of the reason why this elevator has already lasted close to 100 years. This is the break for the voice machine teh brake. We have the original controller here. Fortunately, the power is turned off. This room was built in 1913, but the National Elevator cut actually was not introduced until 1921. Tell us about this antique controller. What makes it different from a modern controller . The elevator is running on the original d. C. Power. Really simple in operation. Does not include a lot of the features we would have in an elevator today, Automatic Door operation, dispatching, push button operation. None of those features are present, but this is the original from 1913. On this side, we have all the relays that actually control the elevator. The Safety Service city circuit, position, speed, and control of the power to the motor. Here is a really interesting piece of historic machinery. Tell us about this. This is one of the main Safety Devices of the elevator system, and the device still exists today even on modern elevators. It detects if the elevator is going into unsafe over speed conditions. It is attached to the road itself, and the car over speeds, bees fly balls would come out, and the governor jobs would come out and grab on to the governor wrote, which would hold the break or the safety on the elevator to cause it to stop. If you have problems, i see right here, we call garfield 7171 for service. Member that is right. Operators standing by. From here, we are going to look at those wonderful elevators that go of the outside of the high rise building that Everyone Wants to take a ride in. Lets go do that. Here we are in the most exciting elevator in the city of San Francisco. This is the outside elevator that goes into the 32nd floor. Tell us about this. We are in one of the tower elevators now. These were originally installed in 1972. 1,000 feet a minute, outside observation elevators, so a great view of the city. Some of the most popular elevators in San Francisco, as you mentioned, and these cars run a lot. They run about 2000 starts per day. About 700,000 starts per year for an elevator like this, and these are pretty hard working. Must be hard to maintain these elevators. Mechanical devices in the rain. This is much more difficult to maintain. Normal elevator installation is all sealed from the elements, but in this case, it is all exposed to the outside, so there are issues with whether proofing and sealing the equipment from the elements. The controls and motors are up here on the top floor. Very simple similar to the elevators we looked at. This is similar to that technology. I saw a crowd of people downstairs waiting to take a ride on the elevated to get this fabulous view. That is a terrific view. Yes, it is great. Can you tell us about the history of the modern elevators . What we consider the modern elevator is the elevator with a safety device that was built in new york in 1853 in response to a freight elevator accident in new york city. Until that time, elevators were quite common in buildings but typically used just for handling freight. Elisha otis elijah otis successfully demonstrated the safety device he had created. Even of the elevator and he cut the device, and he did not fall. Everyone was impressed by that. In 1857, the oldest Brothers Company installed their first passenger elevator on broadway in new york. Believe it or not, many of those first elevators were actually started and stopped by a hand broke. What drove those old elevators . What was their motive power . In some cases, they might have even been hp. And then changed to electric . Electric cited to come in the 1890s, and that was around the time when the elevator stopped from Material Handling and started to be used more frequently for passengers. In 1878, there was a demonstration of the other thing that allowed architects to build taller buildings was the advent of a Higher Quality steel manufacturing. In 19003, the first production year track models were introduced, that it was when things took off. That mostly happened in new york city . Lower manhattan was the first place that took off, then chicago. Those early passenger elevators always had an attendant that would take a passengers request and then operate the car. The big change was the emergence of a electric elevators. Starting in 1880, the electric elevator allowed building dollars to go much higher. We evolved from steam hydraulic elevators to the electric elevators that are not that much different from what we are going to see now at the top of the tower. This is the steam room on the top of the state st. Francis. On top of the state francis. The equipment you see painted green, that is all the original equipment from 1972. We are just now in the middle of modernizing this equipment. Why modernize . Doesnt the equipment works fine . It does, it is of analog and intensive, and there are some additional controls. Let me introduce the foreman to you. This is vince. He can do a better job explaining the project details. What is happening here, what are you doing . We are doing a major modernization. We are tearing out the old system, logic controls, and generator controls, and we will be going over to solid state. This is not your standard selector. It does not have a tape that runs it. Because these are outside elevators these are unique to the city. And this is going away with the upgrade. That is right. None of these will be here. We have retrofitted three elevators so far and now were doing the outside cars. So this is what will be replacing this will be replacing the generator controller and control system. We are down to about 15 or 20 relays, down from about 100, which means much less maintenance. This thing had been running for about six months now, but we still have eight cars here to do. Great job. We have looked at past the elevators and present. Now lets look at the future. We are taking a look at some of the most exciting technologies in elevators. George, tell us about destination elevators. This is the technology of the future. Probably the biggest single investment in elevators. San francisco has embraced the technology more than any other city in the country. A big advantage with us is passengers get to their floors sooner and there is more opportunity of customization of features for individual service. Four issues of security and accessibility, this is a big advantage over traditional elevators. Digest i understand these are rehabilitated upgrades of existing elevators . Yes, these are upgrades to the original elevators from 1980. All the controls and wiring has changed but the physical mechanisms are the same. How much energy to these use . With all of the things that we did hear, Energy Savings is about 50 from where we started. That is a significant improvement for such a major system. Tell me how it works. This is the hall keypad, which controls the elevator. The system asks where you are going before you get into the elevator. Imagine you are going into the airport. You would not get on the first airplane departing, you would get on the airplane that is going to the city you are going. We are doing the same here. In this case, we are going to the ninth floor. This building has security, so i also have an access card, which gives us permission, and then we go to the assigned elevator, which is elevator a. And this is only stopping at floors 4 and 9. I do not see any buttons in here at all, except for the door and the alarm. We only have the standard buttons required by code and safety, but there is no need to have floor numbers anymore. And it does not make a lot of stops. It goes to your floor and everyone else. The system it efficiency, because we do not have to make as many stops, is a big improvement. We have invited jessie from the center for independent living to come and tell us how destination elevators interfaced with persons with disabilities. When destination elevators storfirst started appearing, thy presented a number of challenges to individuals with disabilities. What happened was, Elevator Technology outpaced California Building code. Building code has a number a provision that makes traditional elevators usable by people with disabilities, but destination elevators presented challenges, particularly with cited. How do you know to get from this keypad to your our corporate car . We had a terrific program where we develop and administer the bulletin, which your help, elevator companies, involvement from the public, and you can tell us the outcome of that. What is amazing about the process is we had both government and private industry, as well as people with disabilities at the table for three years creating these accessibility standards. What we are doing here is being looked at by the department of justice access board and state architects office. That is how good our standards are. Would you like to see . I am going to push the access key which will activate the voice. I want to go to floor 24. Ok, to the left. Elevator j has arrived. That was smooth. I am getting a text message. It is amazing, these destination elevators. Pretty soon, the signal that changes the system will be able to be routed through blue tooth and your phone, which is amazing. My iphone will be able to access the controls. In paris already, they are rounding the pedestrian signals through blue tooth and into peoples phones. So the future is really exciting and technology will make it quite a journey for everybody. Thank you for joining us. Thank you for having me. So now i would like to introduce the chief engineer. Can you tell us about your experience . There were a lot of anticipation about how people would respond. At first, we had to get in front of people to direct them from their habits. Early morning, they are more into carrying their coffee and going inside of the elevator and then spilling their coffee to hit the keys. We got right in front of them, stopped them and told them exactly what they had to do. That helped out a lot. The other thing that helped were the lights in the lobby would tell them where the elevator was. A lot of these systems have not done that. We were the first to do that. The nice thing is weve got less spills in the lobby, too. You get into the elevator in the morning, and somebody is standing in front of the buttons and you cannot get to it. People are fighting each other, spilling coffee and stuff, so this works out well. Once you get inside, you are going to the floor that you have already decided on the outside. It really helped traffic flow and security as well. Would you say your experience has been a good one . Excellent. Very positive. Lets go on a tour. Here we have the network control. There are two groups here. In case one fails. There is automatic redundancy. Each of these cables connect to each device and communicates with the main global server. The previous equipment was a relay control, and it was analog logic. This has many advantages in that it can be Custom Program to and can readjust to changes. It can do a multitude of things, like the lights blinking in the lobby. Those are all programs that can be controlled by this equipment. Before, this room was filled relay panels collect that clicked. They had had a big rotator that told the person or the elevator was. We can level these cars with an 1 millimeter. It used to vary on the temperature by up to half an inch. That caused tripping hazards. Now you walk out and it is a smooth transition. It is important for the disabled as well. Over here is the controller. But this does is it provides information to the elevator where to go. Receives commands from within the elevator and from the destination dispatched central dispatched central. These elevators are precisely the electronic breaks, so they need to be very precise. In accordance with the vfd to supply power to the elevator motor, which is right here. These are original d. C. Drives. D. C. Was in place at the beginning of elevators. It was easier to control. Currently, new elevators are ac drives. But they are so expensive to replace and waste of materials. We have made it more efficient by providing aid to the electrical system to drive it. This is controlled by the same transistor that controls the toyota prius. When the elevator is empty, the counterweight polls the elevator and it generates electricity by breaking. The same thing as in your toyota creosote or another hybrid car. Prius or another hybrid car. Here inside we have the ibtv drive. This is important for landing of the elevator. Also, acceleration and deceleration, if there is instability in a car, can be reduced. So we have taken a ride in an antique elevator. This was an elevator built in 1913. We have checked out current Elevator Technology. These were installed in 1972, outside observation elevators. It is not standard because there is no tape that runs it. But shane we have seen the future of the Elevator Technology. I am going to push the access key which will access the voice. This has precise generation of power, which is important for highly acrilan the landing of the elevator. What happens next week and not know but it will be exciting. Thank you for showing us this interesting technology. You. When i first moved here people come to San Francisco to be the person you want to be can be anyone you want. The community is so rich and diverse that im learning every single day San Francisco is an amazing photoy town historically been base on evolution and that applies to every single professional field including philanthropic arts today what i do is photo based art manifests traditional forest and some colonel lodge and other frames of Digital Forest is a meeting that has been changing like super rapid and the quality is not extended by the medium if you took forest in school or you get a job in a newspaper theyll give give you a list of how to create a philanthropic story my goal to break down that model and from a to b that is unique and allows the ability to incorporate different types of i believey about propels someone through the rise and a fall of their own experiences one of the main things im trying to contribute it unconditional narrative form the narrative art of photograph the in between of photos how does a group of photos come together as how to use the space between photos to alight emotional responses from the audience and bring innovation and create bodies of work that narratively function the way that photos do San Francisco as the commission came out and you visited me and one of their prerestricts was to find an art with enough work to fill a large says that a quad down the hallway downstairs and we hung that quad to feel like a train station that constant sensation from all Different Directions some of the major characteristic of the landscape festivities the blur of the train their 70 Miles Per Hour and theyre not perfect as opposed to to what landscape will look like it creates a dichotomy for people insides the train not just the story of the subject it is not just the visual design the composition juxtapositioning, etc. Not just all autobiography boohoo it creates pictures with meaning within them and then some of the portraits feel awkward some of them feel welcoming and the person that mime making the picture is really comfortable and other ones feel awkward and weigh i didnt and tense that sensation is counter to what we feel like makes a successful portrait that sensation makes that work it is hard to be an artist in a city is 100 percent focused an business the cost of living is expensive and to value your success not scribble on financial return creates a conflict between the paramount egos in San Francisco today. You see a lot of artists leaving for that reason because you need space to make work my ultimate goal to make work that firms people firms this gift and just the experience of life and of their worst and of the amazement the wonderment of everything around ushi, were l. Chair sesay good morning. I call the board of directors special meeting of september 10, 2020 to order. I am the board chair. The Board Meeting is being conducted pursuant to provisions of the brown act and recent executive orders by the governor to facilitate teleconferencing to reduce the risk of covid19 transmission. Ordinarily, the brown act sets strict rules for teleconferencing. The executive order has suspended those rules. As noted on the agenda, members of the public may observe this meeting by sfgovtv and they may offer Public Comment by calling the published Public Comment phone number. Id like to welcome members of the public and staff who are watching us live on sfgovtv
