Question About Old Rebar Designation

[RanarT]

Hi Everyone!

I have an old civil drawing. I guess it comes from the 80's. This drawing was made by a British Consultant. My difficulty is to dechiper the rebar designation. In the drawings, one of the rebar is written as 1601. What does it mean? I want to know the diameter and the spacing. Here is the picture, I mark the rebar designation to decipher with the red mark below

Thanks for your help guys.

Looks like a rebar schedule tag.

Is there a table or schedule in the drawing set that defines the bar size and spacing?

Yes. There has to be a schedule somewhere. Also looks more like 60's or early 70's with the bent up bars.

Metric prefixes.

16 for a #5 bar.

10 for a #3 bar.

Etc...

Usually Seppe (and I think you're right in this case), although I've also seen the bar lengths coded in to the schedule designation.

I suspect 1601 is 16mm bar dia. bar number 01 on the bending schedule. Without the corresponding schedule it's hard to say for sure. Have you got a clearer shot of the drawing?

Definitely scheduled bars, and the 10 and 16 are probably the sizes. For the quantity and/or spacing of bars, you need the plan.

Hello everyone!

Thanks for the answers and I am sorry for the late reply.
This drawings are made by MW Kellogg. They built ammonia-urea Plant & its Supporting Facilities. The drawings which I attached above is the Jetty Drawings.

And I think that is the main problem. Since it is an old drawings, mostly the supplementary documents are lost. Do you guys have previous experience with this company? If you do, then maybe you have the Bars Designation. I assume that they have the standards drawings for the same works which is applied for other projects.

Thanks again for your help.

MW Kellogg was a Houston, Texas, USA company that was purchased by KBR & Halliburton and KBR has since spun off (with MW Kellogg) and is a company just called KBR and still headquartered in Houston, TX. They are still building fertilizer and ammonia-urea facilities.
