Deepsound Posted March 29, 2011 Report Share Posted March 29, 2011 Height : 50 m # of levels : 15 Earthquake resistance : magnitude 9 # of workers : 300 Heating : geothermal energy + solar panels Building : 2 days Insulation + interior decoration : 4 days Total : 6 days... Water saving included. Just look at this... Quote Link to comment Share on other sites More sharing options...
Deepsound Posted March 29, 2011 Author Report Share Posted March 29, 2011 According to you, is it possible to use this to rebuilt Chch ? I'm thinking to the homeless people, providing them fastly a place to live. Quote Link to comment Share on other sites More sharing options...
Ira Posted March 29, 2011 Report Share Posted March 29, 2011 Earthquake resistance : magnitude 9 Is that magnitude 9 with a very shallow epicenter directly below the building? Or 50 miles away and deep? 200 miles? Magnitude is worthless for comparing building stress. According to you, is it possible to use this to rebuilt Chch ? I'm thinking to the homeless people, providing them fastly a place to live. 2 days to build the building, 12 months to get permits, 24 months to build the tooling to construct the prefabbed parts.

alanmin4304 Posted March 29, 2011 Report Share Posted March 29, 2011 Most people in Christchurch have no desire to live or work in multi storey buildings or in brick or brick veneer buildings because of the damage done to many of the buildings built that way. For the same reason buildings with large areas of glass that would break in a quake are not popular either. Most people you talk to would be happy to live in a single storey weatherboard home even though some of them tried to bury themselves with the liquifaction.

Adrienne Posted March 29, 2011 Report Share Posted March 29, 2011 Great in theory. The problem will be getting the workforce to build multiple prefabbed parts. NZ just doesn't have the population base to draw from. We have a fairly new 3 storied boarding house next to us at the school where I live. A lot of it (concrete slab walls etc) was constructed off site and trucked in, then put in place using cranes. Even with 12 months planning they ended up pouring a giant concrete ceiling/flooring beam on site, as the people off site constructing it were unable to keep up with the pace. I agree, I can't see ChCh people wanting to go back into multi story buildings. I am going back down there in two weeks and I am not terribly happy that the only motel accomodation we can get is in a 2 storied block. When I was down there about 3 weeks ago I vividly remember watching the two level building next door to where we were staying leaping around in the 4.8 that struck while we were there.

alanmin4304 Posted March 29, 2011 Report Share Posted March 29, 2011 I was talking to a young English guy in the house accross the road a few days ago and he said that coming from England he was very keen to buy a brick house rather than a weatherboard "T" house like they were renting. After the quakes they now have their heart set on a weatherboard place. Sister in law with husband and four kids lives in a two storey house in Templeton which has avoided any real damage. The bedrooms are all upstairs but everybody sleeps downstairs. The timber frame houses we tend to build are very flexable which means they will move a lot but generally return. The upstairs of course realy gets serious about the moving a lot and scares a lot of people. We have friends who sustained no real damage to their flat but are still sleeping in the car in the driveway. Quote Link to comment Share on other sites More sharing options...
Deepsound Posted March 30, 2011 Author Report Share Posted March 30, 2011 Is that magnitude 9 with a very shallow epicenter directly below the building? Or 50 miles away and deep? 200 miles? Magnitude is worthless for comparing building stress. Yes I know it's not so simple. Here are the only informations I could find about : Level 9 Earthquake Resistance: diagonal bracing structure, light weight, steel construction, passed level 9 earthquake resistance testing 6x Less Material: even though the construction materials are much lighter(250kg/m2) than the traditional materials(over 1500kg/m2), the floors and walls are solid with surefootedness, airtight and sound-proofing 5x Energy Efficient: 150mm thermal insulation for walls and roofs, triple glazed plastic windows, external solar shading, heat insulation, fresh air heat recovery, LED lighting, yearly HAVC A/C energy consumption equivalent to 7 liters oil. 20x Purification: after 3 levels of purification, the purification efficiency for fresh air reaches 95%-99.9%; air exchanged 1-2.5 times per hour, and indoor air is 20x cleaner than out door air 1% Construction Waste: all components are factory made, construction waste, mainly package materials, result from on site set-up only and amount to 1% of the total weight of the building. Environmental friendly, comfortable and secure elements. Sustainable building. Quote Link to comment Share on other sites More sharing options...
Deepsound Posted March 30, 2011 Author Report Share Posted March 30, 2011 @ Alan & Adrienne : Yes, you're right, the timber frame houses are more adapted for. I wasn't thinking about building something as higher as this one. Even if it is technically possible, it is just psychologically unconceivable because of the trauma. I was just impressed by the speed and thinking of the homeless. I would tend to say yes, but according to you, is it a good alternative to use prefab wood frame homes instead of brick houses, usual in Chch ? And as Ira said, what about the permits ? I don't know the shipping cost though, but does it sound definitely as sci-fi to import it if it can't be produced locally ? (sorry, I'm ignorant about NZ economy and the costs inherent in shipping) Because, as you said Adrienne, if NZ doesn't have the workforce, anyone can build pretty fastly a pre-engineered wood frame panelized home with a project manager or just in DIY, depending on experience. There are now some models, with eco-construction standards, healthy and well insulated, which don't look like prefabs anymore. :dunno: Quote Link to comment Share on other sites More sharing options...

spoon Posted March 30, 2011 Report Share Posted March 30, 2011 placemakers frame and truss in harewood were building relocatable accommodation , im not sure if they still are but they were pumping them out pretty fast. even though it was aq 6.3 and the 7.1 we had did less damge the magnitude of the quake dosent effect that too much there is a measurement called peak ground accelartion from wiki "Peak ground acceleration (PGA) is a measure of earthquake acceleration on the ground and an important input parameter for earthquake engineering. Unlike the Richter and moment magnitude scales, it is not a measure of the total energy (magnitude, or size) of an earthquake, but rather of how hard the earth shakes in a given geographic area (the intensity). The Mercalli intensity scale uses personal reports and observations to measure earthquake intensity but PGA is measured by instruments, such as accelerographs, and it generally correlates well with the Mercalli scale.[1] The peak horizontal acceleration (PHA) is the most commonly used type of ground acceleration in engineering applications, and is used to set building codes and design hazard risks. In an earthquake, damage to buildings and infrastructure is related more closely to ground motion, rather than the magnitude of the earthquake. For moderate earthquakes, PGA is the best determinate of damage; in severe earthquakes, damage is more often correlated with peak ground velocity.[1]" http://en.wikipedia.org/wiki/Peak_ground_acceleration we had a measurement of 1.8 - 2.2 depending on the area bare in mind 0.5 would topple most major cities around the world Quote Link to comment Share on other sites More sharing options...
Sophia Posted March 30, 2011 Report Share Posted March 30, 2011 I find it hard to believe that NZ doesn't have the workforce or the natural resources to fix itself. Most of the time it lacks a decent leader to get people together to do it is all, in my opinion anyway. I also think we could feed and clothe ourselves pretty well without needing to import if China didn't make things so irresistably cheaply.

SamH Posted March 30, 2011 Report Share Posted March 30, 2011 They really needed to count the "man hours" on that video too. Several hundred men working over two days is probably equal to a dozen or so guys working over a year. Quote Link to comment Share on other sites More sharing options...

smidey Posted March 30, 2011 Report Share Posted March 30, 2011 that is great to watch but it reminds me of the idea of a rechargable electric car. "Hey, look at me in my car with no emmisions at all, the world is saved!" meanwhile, back at the ranch there is a coal or nuclear plant generating the energy in the first place. all that construction method does is make the building erection happen faster by shifting the labour from on site into a factory which does save time in the long run but not a major percentage over all.

livebearer_breeder Posted March 30, 2011 Report Share Posted March 30, 2011 They are designing electric cars that recharge off there own kinetic energy. We have the technology, unfortunately everything is owned by large greedy conglomerates that will squeeze as much as they can get out of humanity before changing. Humanity has a big problem. The earth is getting angry Quote Link to comment Share on other sites More sharing options...

smidey Posted March 31, 2011 Report Share Posted March 31, 2011 my brother in law has a prius & is getting about 5.5L/100km out of his. the latest nissan micra is rated at 6.6 (the prius does more open rd driving so the micra will rate better in those conditions) so the gap between them isn't that great. especially when you take into count the $6k he just spent putting new batteries in the prius.
