Tremie II

thread255-423825

Tremie II

Tremie II

(OP)
I am currently working on a project involving the construction of bored piles and I encountered this specification of "tremie II" in the construction drawing issued by the design engineer.

I searched high and low for the definition of "Tremie II" and am unable to find any information about it. I am aware of the tremie concreting method but not sure about the "II". Is there even a "I" and "II"?

Can someone please enlighten me about what it means?



Thank you in advance.

***I am sorry, I posted in the wrong section. Can the admin help me place this thread in "Foundation" instead? Sorry for the mistake.

RE: Tremie II

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.

RE: Tremie II

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

RE: Tremie II

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

Keep reading!

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.

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

RE: Tremie II

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.

RE: Tremie II

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

RE: Tremie II

(OP)
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.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.
