I really don't know. I think we need trained professional/expert to comment on such construction.
I noticed you like to raise questions on the safety/integrity of construction projects. There are many such examples, here is one of them..
You also commented some time ago with colorful language that the CEO of the biggest company in this country is leaving !!
Corinthia, Is it wrong to raise such issues? I am concerned because I live near this stretch of road and will eventually use the LRT. Raising such issues is to share and avoid mishaps. That particular contractor caused three mishaps already and that caused me to have little confidence on its work. FYI a large crane positioned below that stretch was too close to the main flow of traffic. I was a few meters from it when it swung its arm over the top of my car. I sat there helpless and I wonder how you wouldfeel ifyou were in my place.
You can raise this issue about my postings with Mr Chang and have the posts deleted.

Did I say it is wrong ? You are entitled to what you deem fit to ask..
Someone made a typo error of your name and you raised a question to him…
Why not you spare a moment to think how he feels ??
