Wow, don't you think you are going out on a limb a bit.
Having been in Dubai for a month how are you able to make such 'confirmation'? Have you reviewed the quality of many buildings designed and constructed by many archites/engineers/contractors. Standards obviously would required that you have considered the codes, factors of safety, and checked the culations. I would think this would take time...
It is perfectly correct that for most small buildings the design is oversized however the matter is else:
Again, you looked at the design for "most small buildings"?
Engineering studies are usually carried out by unqualified people so each singularity in any building could lead to a serious issue if not checked properly by a third part reviewer qualified.
How do yo know this? Have you evaluated many engineering studies and the qualifications of those who performed the evaluation. Which studies are required to be reviewed by qualified third party revieweres and how many of those have you found to be reviewed by unqualified engineers?
Additionally,on site, nobody controls what the contractor is doing. Some drawings approved by the Third part checker and approved by DM are modified by the contractor on site.
Are you talking about your experience in your particular job or are you generalizing. "Nobody controls" is that because the party contracted to do so is negligent, lazy, or... Would you think that there is a "professional" obligation on your part (or your employer) to point out this failures for the greater good of the public (if these might lead to economic or personal injury lossess).
Many owners begin to complain about durability of concrete here in UAE.
Low cement quantity, low cement ratio are a big problem here.
How do you know this? Have you reviewed and studied reports about cement quality. And are those for one project or many projects? Or is it rumor/innuendo...
Same with cement ratio? Have you reviewed reports about the concrete placed in any building and found the w/c ratio to be low? And if so, has the contractor not been notified? Does he have an obligation to correct? If not, then what is the basis for the statement...
Many accidents occur during the construction works. Unqualified people on site is responsible for this issue.
Accidents do happen but they may not be indicative of the qualifty of the Works (buildings, bridges, etc.)
Do you remember in August that one excavation work was flooded due to unproper dewatering calculations on site?
I don't remember but this has to do with preparation for the Works and not with the qualifty of the Works themselves. Accidents do happen, many times due to negligency and sometimes due to fatigue.
I thought you had only been here for a month? How do you know about the August flooding and that the calculations were improper?
Do you remember that during construction a bridge collapse two weeks ago?
I do and this has to do with 'false work" (scaffolding during the construction of the bridge) again not representative of the quality of the construction itself.
My "questions" above are by no means meant to defend the construction industry or to infer that you are not knowledgeable. However, I often hear statements of "poor quality" being made by individuals who are not qualified to make them. I mean not qualified to make such statements about an entire industry or building standards in general. The poor quality of bathrooms, tiling, kitchen cabinets, lobbies, and finishes are not necessarily indicative of poor quality when it comes to safety or durability of the structure itself.
What occurs many times is that rumors of "bad construction" are passes around and someone comes along and says "I am a structural engineer and..." without any substantiation (other than the statement) and then others say 'well it must be true....".
I imagine there are some crappy contractors and engineers out there but not just in Dubai - which keeps consultants, insurance companies and lawyers in business. Everyone needs to eat.
