Hi All , I may suggest we meet at the Ara Damansara show room on the 12.3.2012 (Monday ) Time 1 pm ( Lunch Break ).

Attendance draw down :- ( at least we can have a joint discussion and know each others) .

A) Johnlhtoh

As my dad called the project manager, he said already finished more than 1K piles.
Because the part above ground was chopped off so we can't see them.
Will start do piles from LRT side & move towards block B. Will complete by April.

This is what info i got la.

Dear Alternative80

I have spoken to Mr Chong who told me the same story . I queried him further that The pile once they drive in to the ground. They must do " PILES LOAD TEXT " to ensure the driven Piles have no further piles settlement inside the ground . He cannot answer Me but need to refer to The project manager again .

Anyway , Our main focus is that their work progress looking from the photos provided is FAR FAR behind schedules.

I wonder is there any Civil engineer in our midst that can assist us??

to assist you guys in terms of ???

you seem knowledgable enough about the issues at hand and matters pertaining to foundation.

just to add on a bit. piling through injection matter does have its merit. the process is less noisy compared to conventional driven piles (those bong bong bong type). piles are basically driven to 'set'. set meaning it has achieved its intended strength. how they determine this is vide their loading of the injection machine onto the pile itself. as the pile is unable to be driven/injected in further to the ground through the desired load, thus it is deemed 'set'.
the other scenario would be having the foundation to rely on friction. this method requires the pile to be driven to set by length. the friction through the surface contact of the piles and the soil itself will provide the required strength to hold the building either from further sinking or uplifts (if any).
but having said all the above, it all boils back down to good supervision. without proper supervision and implementation, the contractor can still cheat lah as in reporting false length, using less injection force as intended.

and fyi, static load test (as per your "PILES LOAD TEXT") is not carried out on all piles. it's only performed on selected piles and there's load to failure or load to certain pre-determined loads. of course, there's also various other tests that can be carried out subject to their engineer's recommendation such as PDA, PIT, statnamic, MLT, etc.

cheers!

who's the main contractor and who's the piling contractor by the way?

Hm true, i think u got the point also.
Anyway, what is the expected completion date? JAN 2013?

Dear Kochin.

Tq so much for your explanation . It enlighten me lots . I m sure you are a civil engineer. ( RU a purchaser too ? )We need ppl like you ! BTW i don not know who is the main con neither the Piling contractor.

That's why we need to meet up and confront the developer and find out more Before its too late ! So far nobody responded to my suggested time and date . Perhaps somebody can Spear head this exercise ?? I will definitely be in it.

from the first page:

Property Name: Eve Ara Damansara
Type: Serviced Residence
Location: Ara Damansara
Built-Up: 680 sf & 1,065 sf
Bedroom: Studio & 2 bedrooms
Tenure: Freehold
Minimum Price: 379,100
Completion Date: End of 2013
Developer: SM Land Group

Then I start to worry about it then.
My parent's Pelangi Utama also took 3 years to complete but slow progress at first 1 year (Roughly same situation like eve suite now).
I wonder if eve suites can be completed 20 floor + shoplot at bottom within 2 years.

What could be the real reason work is so slow? Units not sold yet?

Look out for the sign board at project site for info of the various parties involved in the condo development.

Gather, discuss, note down what to ask and meet the developer is no harm and have peace of mind. Start to exchange phone number, a leader call to arrange all for time and place.

1 floor 1 month, 20 floors, need 20 months..

If 1 month 1 floor, not only buyers need to worry, the contractor also need to close shop. Average have to achieve 2 to 3 floor per month for typical floor. To complete in 2years is a very tight schedule but possible. If after piled 1000 nos as claimed and yet to start any load tests such as MLT and PDA, the work dont seem well planned. Load test should have been done now and continue with pilecap. The progress is too slow.

1st.. it need alot of manpower, 2nd.. the structure if not strong enuf then start another floor is risky.. could collapse.

Progress depend on planning. Manpower is part of planning. If any building can only progress at the pace of 1 floor per month becoz "structure not strong enuf then start another floor is risky..could collapse" then max building height can only goes up to 36 storeys @ 1 month per floor for 36months or 3years S&P juz to complete the structure. Developer need to have 4years S&P for taller building.

Concrete needs time to cure to achieve its optimal strength. If developer rushes the schedule and rush building quickly it might even compromise the structural integrity of the whole building. From my experience at least 2 weeks' of curing is needed for concrete slab to cure before it achieves its maximum strength. Of course you can plan and do everything without time wasted but then it will cost a lot of $$$$. I don't think a small time developer has the resources to do so and even if they did it will cost a lot more. A similar case is not long ago in Sentral the whole floor collapsed while casting the floor slab, something similar like this can happen.

It is pretty clear that this developer is behind schedule, obviously they are not revealing the true reason so investors have to keep the pressure up on them.

To achieve max strength should be 28 days, not 2 weeks. Collpase at Sentral due to failure of formwork support and not failure of the casted slab. There is term call "slab back propping" to check adequacy of temporary works. Regardless small or big developer, S&P is still same 3years for both.

Yes fuji it is 28 days but a lot of developer does not wait for that long, normally at least 2 weeks.

No matter how u look at it this development is behind schedule. I actually find it hard to believe that someone said the developer said they have already driver in over 1000 piles. If they did you would see left over piles all sorts of other debris all over, not some brand new piles laying around like nothing has happened.

northface, jz to correct u again, its the contractor dont wait, not the developer. But in fact dont have to wait if using back propping. And its a fact that by looking at the photos, the progress is damnn slow!! And the reason behind, only the developer knows.

Added on March 5, 2012, 11:51 pmFr the photos, after the earthwork, the piling jz started but not 1000nos driven as claimed.

Watever is it, they r behind schedule now n we purchasers demand an explanation from SMLand...
