webfact Posted October 4, 2017 Share Posted October 4, 2017 Three possible causes for the collapse of a bridge in Chai-nat are identified By Chalarntorn Yothasmutra The Engineering Council of Thailand has summed up three possible causes contributing to the collapse of a bridge under construction in Chai-nat province. The council president, Mr Thanet Veerasiri, said on Wednesday that the steel structure supporting the concrete pillars could not stand the weight of the concrete blocks and the vibrations from a cement mixer truck at the construction site might have shaken the supporting concrete poles to the point that caused the concrete blocks to cave in, prompting the truck driver to jettison from the truck. The riverbank where the construction was under way sustained more soil erosion than the opposite side of the river, resulting in a gap in soil where the supporting concrete poles were driven into the river bed.

Somtamnication Posted October 5, 2017 Share Posted October 5, 2017 Yes, correct: The first was bad construction. The second was bad construction and the third, you guessed it, bad construction. Link to comment Share on other sites More sharing options...

Only this isn't fun and people's lives were at risk. Vibrations from a concrete mixer? Dear Lord above us that's amateur construction. Link to comment Share on other sites More sharing options...
SkyNets Posted October 5, 2017 Share Posted October 5, 2017 "Vibrations from a concrete mixer" so the tick-over of a diesel engine damaged the supporting concrete poles? Whats going to happen when Somchai drives a full minivan into it? Link to comment Share on other sites More sharing options...

dinsdale Posted October 5, 2017 Share Posted October 5, 2017 They seemed to have missed a 4th and 5th possibilities. 4th, two nearby motorcycles started their engines at the same time and the 5th which is the most likely, cost cutting in construction and construction materials so pockets could be filled.

The second was bad construction and the third, you guessed it, bad construction. None of the above. It was the rain as it affected the river bank. The rain get's blamed for everything that goes wrong in Thailand. And when it occasionally does something right like help grow rice they tax it.

Artisi Posted October 5, 2017 Share Posted October 5, 2017 Guess they didn't look at incompetence as a cause .... Nah! couldn't be that - this is the hub of highly skilled construction engineers. Link to comment Share on other sites More sharing options...

JAG Posted October 5, 2017 Share Posted October 5, 2017 There were three possible causes: 1, The bamboo wasn't strong enough. 2, The bamboo wasn't long enough. 3. The bamboo wasn't thick enough. Link to comment Share on other sites More sharing options...
ChrisY1 Posted October 5, 2017 Share Posted October 5, 2017 It's been 3 or 4 days now....this is a catastrophic failure .......detecting the exact reason should have been determined by now.....and not just give 3 vague guesses! But, this is the usual way a cover up is developed here in Thailand for an incident of this nature... It will cost the company, but they will likely not lose too much face or money, if and when a reason for the collapse is published. Link to comment Share on other sites More sharing options...
Happy Grumpy Posted October 5, 2017 Share Posted October 5, 2017 The fault is clearly with the Burmese laborers for not understanding Thai engineering. Surprised the rebar wasn't hooked up to the mains and it electrocuted everyone. Link to comment Share on other sites More sharing options...

The Old Bull Posted October 5, 2017 Share Posted October 5, 2017 Every bridge has three potential sources of problem 1. Design 2.Construction 3.Maintenance If any of these three are not properly addressed the bridge will fall down. Link to comment Share on other sites More sharing options...
