Asking the question, what is a highrise building . What what makes this different from any other building . We have the architect for this project. This is actually two projects . That is correct. We are building a little over 100 units, hud found it, affordable housing. There is a community center, Child Development center, a youth center, and there are a couple of retail spaces, the tenant of which is still to be determined. Are these highrise buildings . They are. A highrise building is a building that is more than 75 feet from the point of Fire Department access on the ground to the floor of the highest occupied floor of the building. Correct. Im glad we agree. It is important to agree. This is a highrise building. This will also be a highrise building. They started construction yesterday. Are the standards for a high rise building for affordable housing, sponsored by the government, are the standards of construction the same as they would be if we were to build a highrise luxury b
The floor above . Because the slabs on grade is a conventional slap, it is not post tension. One of the things the building designers do is to make the floor as thin as they reasonably can. There are several benefits to that. First of all, it reduces the mass of the building. We have 7. 5 inch slab. Conventional slab would probably be 10. 5 inches, which is about 25 more concrete mass. It also reduces the overall floor to floor height, which helps with the architectural facade and the square footage. One of the things people are always looking at is decreasing the floor to floor height, especially in San Francisco where we have clearly defined height limits, and maybe could squeeze another story and there if you are good at it. We see a lot of people struggling with the thickness of all these assemblies, both the Structural Assembly and non structural which might be above the ceiling, where we have the heating, ventilation, plumbing, fire sprinklers. You say that the finish of the conc
Between market and mission streets. We have all of the people who are part of the project, including the contractors, the design engineers, soil engineers, structural folks.

Be heated and cooled with forced air, that is where you get the dropped ceiling. Also, corridors and public areas. The dwelling units do not have airconditioning . They do not. They have heating but not air conditioning. Do they have outside air . Absolutely, they have windows and they also have a system called zduct, which provides for a share even when the windows are closed. One of the reasons they have the systems, ever since 1974, chapter 12day of the Building Code requires that you have sound transmission isolation between dwelling units so they cannot hear their neighbors, and between the residential units and the cars at outside. That specifically says that if you are in one of these noise areas, which are on the transit corridor, that you must design the building such that you can ventilate the resident units with the windows closed, meeting all the Noise Control requirements. You close the windows and you still have enough ventilation, which is why people use zducts. That is
Long well heading out to the mcarthur maze with no major problems, it is getting busier at the toll plaza as well and as you can see metering lights are being turned on, lets go back to the desk am being. Oh, my gd, its nose is up in the air. Two 16yearold girls died in the crash. We have more about the disaster, we have katie and travel is delaying for another look at fso, alex, you spoke with the chairman of ntsb a little while ago . Reporter thats right, dave, the head of the ntsb told me earlier this morning they will likely sit down and interview the pilots later on today and that will be an important interview. They are trying to get a sense of what went wrong in flight 214. The wreckage remains here at fso. This was just a training flight and saturday was the first time he had flown that particular type of plane into fso. It was a boeing 777 and of course he came up short slamming the tail into the runway. These are photos released by the ntsb. Oral the pilot is experienced and
