| 1416867 | 2016-03-05 00:45:00 | because balconies are designed to hold the weight of it being full of people. . Yeah and lifts say X number of people too....or x kg. Then you work that out and reliase it's about 60-70kg per person, and you look around and see some of the people in there with you are way more than that. So that would be the lift manufacturers fault? Decks are designed to fit a number of people comfortably, not jammed in like rats and all jumping up and down. Not to mention, how old it was too..... |

| 1416869 | 2016-03-05 01:31:00 | the thing that i see is there is holes in the walls for the 11 or so joists, but the balcony only has 2-3 joists sticking out like the broke under the floor. it will be interesting to find out the cause of it. |

| 1416870 | 2016-03-05 01:35:00 | "Another witness said, "you could see it bouncing, yeah and the balcony was just bouncing up and down. You heard it crack and just saw the end of it. Police had told them to stop but they didn't and it collapsed, falling 4m on to the bitumen below, he said." www.radionz.co.nz Like I said, Darwin Rules :badpc: Cave Creek was different. The basic design was ok, but instead of the cantilevered beams being bolted to the base structure as per drawings, they were nailed. When loaded the nails just pulled out, the timber didn't fail. (All the best DOC field staff who would normally have built the thing had left due to eternal restructuring and cost cutting) |

| 1416873 | 2016-03-05 02:25:00 | i may been wrong on part of it. just seen a another pic and it looks like a lot of the joists where attached by hangers. that would explain why theres only a few bits of joist sticking out of the balcony. |

| 1416874 | 2016-03-05 03:24:00 | Personally I wouldn't trust any domestic cantilevered balcony that didn't have any support columns. Then there is the water ingress problem that could cause hidden rot. Maybe rental properties with balconies should be checked periodically by a suitable building inspector or structural engineer, like the bush walk bridge structures are in the Wellington Regional Council area. |
