Agreed. No need to flog the skeleton of the horse.
V. Bala has already corrected his spokesman that it should be called a flood.

And touching the concrete aka surface will not cause sinkholes...
I think you mixed up concrete works with road surfacing.
How does a sinkhole form? "Cover-collapse" sinkholes occur when groundwater causes underground gaps that grow so big the ground above can’t support them.
Water from a ruptured underground waterpipe can have the same effect.
Nonsense. Service detection is mandatory if you want to carry out any earthworks in SG. This rule is very strictly enforced. I know that from personal experience.
And touching the concrete aka surface will not cause sinkholes...
It is a loss of groundwater, creating an empty space underneath and the soil loses pressure.
Waterpipe is constantly under high pressure. The effect is different.

and sinkiehole. you are stuck in this shittyland after you go into it and cannot get out.
agree?

The effect of soil being removed, leaving an empty space aka hole is the same.
Depending on the nature of what lies underneath, the reasons can differ.
Sinkhole caused by ruptured waterpipe will look like this.
Nonsense. You are talking rubber stamping exercises. The rules are weakly enforced. It is finger-pointing routine and downstreaming the blame. I know that from personal experience. And when I say concrete, I do not mean roads only I mean buildings and structures as well. You see more concrete roads in Shanghai than Singapore.
We would see many many more incidents with underground services damaged by excavations if the rules were as weakly enforced as you claim. It is not just rubber stamping.
If there is one thing that the Singapore contractor fears its having his jobsite delayed or stopped because the excavator damaged a cable or pipe. The fines are very high.
wheres the hole?
If you are familiar, you should know how the PE system is abused. 65 yeard PEs are used to endorse highly contentious projects, which I know I few. They sign off knowing they are so old sure no caning or lighter sentence. Early PE standards are very low. Also to sign a piece of rubber stamp paper can cost 800SGD just to certify obvious things that need not get certified like put a 50kg safe on steel plate in the office. The high fines are just loud air noise. Do you think the Nicoll Highway crash was not known before the incident? Do you think the MRT problems were unknown till today? All necessary voices were raised but our high and mighty LTA bo huey. You can bury paperwork, you cannot bury engineering science.
