If I see correctly, your pile is Ø180cm. Maybe designer ask you to use two tremies in order to shorten the concreting time? We do it in case of diaphragm walls, never saw that in piles.

Just guessing.

I would look to the project specification to find the definition of "Tremie II". If it is not there, ask the design engineer.

You can show anything on a drawing as long as you define it in the specifications.

Keep reading!

Agree that you will need to dig into the specs. But, are you located in Malaysia? I found this:

Look at their products list...

Thank you everyone for the response. I have read the specs and it only described the tremie method of concreting which is the norm, not addressing the true meaning of the "II".

Okiryu is right, I'm in Malaysia. Basing on the web page Okiryu shared, I'm guessing the "II" might be describing the workability of the type of concrete best for tremie e.g. high slump.

I'll continue digging and share what I find here. Once again, thank you all for sharing.

f-d:
And try to make sure the specs and dwgs are consistent... else, you may have to live with the specs...

Whether the specifications or the drawings control should be clarified in the contract for construction. We always make the drawings control in case of conflict.

In your clouded area, I think 0.35 is the W/C ratio...

Hi everyone. I actually contacted the concrete mix supplier and inquired.

Apparently, the number represents the slump of the concrete, considering the workability needed when dropping the concrete through tremie method.

Tremie I = 125mm +/- 25mm
Tremie II = 175mm +/- 25mm
Tremie III = according to the designer's specifications. If I remember correctly, if bi-directional static load test is employed, the test pile will require concrete with slump of 200mm due to the sacrifical jack. In this case, tremie III will be used.

He also said that in order to achieve the required slump, admixture are used although he did not go into details.

I am not sure if this is only common in Malaysia but if your country employs this categorization, please share.

Again, thank you for your feedback and help.
