Overloaded soil truck likely causes concrete slab collapse in Bangkok

Because  - Somchai the road builder -  "That looks OK, you could drive a truck over that..."

Definitely MEA fault. Even if truck carrying 36 Tonnes the concrete slab should have been designed for 54 Tonnes (1.5 times SWL, Safe Working Load)

Appears the slab didn't fail the road base (support) did.

If that is the case why is slab bent in the middle? would expect slab to be straight if it didn’t fail.

OK think of this way. Lay a piece of wood between 2 bricks and jump on it. It breaks. Lay that same piece of wood on a solid surface and nothing happens.

Had the slab been supported equally and continuously or sufficiently that would never have happened. More of an engineering fail than the concrete.

Also looking at it but couldn't be sure, it looks like 2 separate slabs. The fold appears to be a joint.

But if the slab had of been on a solid surface there would still be a solid surface in place when slab removed. How would MEA be able to carry out underground work if a solid surface in the way?

The article clearly states “Concrete Slab” singular if 2 Separate it would have said “SlabS”

But then we are just hypothesising.

I reckon that Somchai the road builder, probably signed someone else's signature on the clearance form for, "All work here carried out to spec." and has now run away.

Doesn't need to be a solid surface to be fit for purpose. Like I said more an engineering fail. As for the slab/slabs for it to fold in that way as a single slab it would indicate a lack of, or complete absence of any reinforcement, again an engineering fail.

So again the point I am making is the concrete didn't fail the application did. Wonder who, if anyone signed off on the works 😊
