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.

Yes, correct: The first was bad construction. The second was bad construction and the third, you guessed it, bad construction.

Like a big game of Jenga. 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. 

[SkyNets]

"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?

[KIWIBATCH]

"Vibrations from a concrete mixer"....absolute BS......and they call themselves engineers...!!!!

[dinsdale]

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.

They are Engineers on Paper only.News paper Engineers (like a news paper you got to Buy one if you want one)

Got to love how everyone in the pic wears them "safety" helmets. Wonder how many did while work was in progress.

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. 

[Jdietz]

I blame gravity. It sucks.

Is that along with the safety boots ....... 

[Artisi]

Guess they didn't look at incompetence as a cause  .... Nah! couldn't be that - this is the hub of highly skilled construction engineers.

[coulson]

Not a single one of them wearing proper PPE

And check this guy out.....

I'm particularly impressed by the safety moccasins, safety trainers and safety flipflops!

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.

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.

[Happy Grumpy]

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.

Safety helmet and sandals ?

Now I know why they like to mix concrete by hand.

And the guy on the right has no hard hat. I guess he probably has an amulet instead.

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.

 

[wakeupplease]

Maybe just corrupt and cutting costs as is normal here

Don't forget materials, the best design in the world won't overcome improperly mixed concrete.

not sure 3 -4 days is sufficient to detect the exact cause ,unless of course it is very obvious, if it's design or construction related it could take quite sometime for a thorough investigation - but this is Thailand and guess we could sort it after lunch if weren't  too busy.
