It seems to me that the developer cut corners by building this apartment house with wood instead of steel and concrete. Reply Posted by The Milkshake of Despair 2 years ago Actually the corner cut was to defer getting the sprinklers up and running. Had they been installed and charged when the fire broke out it would not have spread so quickly. Reply Posted by AnonArch 2 years ago MoD, how in the world do you get the sprinklers “up and running” during the framing stage? The pipes do go up at certain points, but there are numerous issues and alterations during construction that do not allow the sprinkler system to be initiated to well into the duration of the project. If you were to fill and drain the pipes during each change and head adjustment there would be no water left at Hetch Hetchy! Reply Posted by The Milkshake of Despair 2 years ago AnonArch – You segment the sprinkler plumbing into under-construction and completed portions. The completed portions can be charged and active while the rest of the building is under construction. Periodically some under-construction segments are connected to the completed segment. During each “annexation” the system needs to be depressurized and you’re back to being vulnerable to a fire, but only for a short period of time. The extension of the completed and charged section of the sprinklers doesn’t need to be done every time a new floor panel is completed. It could be done once a month for example, not even wasting a swimming pool’s worth of water. On this 360 Mission case it looks like floors 1-7 were all framed. If the sprinklers were active on those floors they would have gone a long way towards preventing this fire from spreading so fast.

Reply Posted by Sierrajeff 2 years ago Periodic sprinkler charging and system expansion would have wasted a heck of a lot less water than was sprayed to fight the fire… Reply Posted by AnonArch 2 years ago Apologies, I did not know the entire building was all framed. MoD is correct if this was further along in construction than I was aware. Reply Posted by Hill 2 years ago Tip to the noisy TV news choppers that tormented the neighborhood for hours and hours on Wednesday – save money and aggravation, get your sky shots with an inexpensive drone. Reply Posted by Rillion 2 years ago Uh, we just had a thread about commercial uses for drones about a week ago. It had previously been banned but a judge ruled against the FAA’s ban. So while the news cannot yet use them, they may be able to in the future. Reply Posted by Wai Yip Tung 2 years ago The drone is super awesome. Lucky that the neighboring buildings are not affected. Reply Posted by RobBob 2 years ago Also they make special refrigeration units to freeze water in pipe segments so that connections can be made live without the water being shut off. Alternatively to keep the entire existing section running you can weld a new pipe with a valve onto an existing pipe and then use a special drill with seal to drill through the old pipe inside the new pipe. Then while removing the drill you close the valve, adding a closed T to the existing connection. Then you can add in your new section of pipe and open the valve when the new section is complete.
