Rebar price per Kg

[Mixtli]

Hi everyone,

I'm just starting a peer review of a concrete project and was wondering about the rebar price per Kg (mat and labour) to have an appreciation of the savings we could get.
Any ideas about this?

Thanks in advance to everyone

 

[cvg]

what country
what currency
what type of project
what is the structure?
what type of rebar?
how large - rebar and structure and total project size?
bridge, nuclear power plant or garden wall?
residential, commercial, industrial, highway project?

Do you need price per kilogram or price per Newton?

 

[hokie66]

nutte,
Now you are just being silly.

 

[Mixtli]

Sorry, i should've said it is in Canada and it's a foundation wall.

and Nutte, "talents" would be fine.....

 

[cvg]

foundation wall for a house or 5 story building? These important missing details will prevent ever getting a $ estimate.

 

[Mixtli]

I've never gotten an estimate like for construction before, and forgive my ignorance, but why this missing info is needed to know the approximate cost? do you need to know the quantity? if you need the quantity and gages I can give you that.

If you are looking for approximate costs, the details may not be that important. It you are looking at trying to justify changes for theoretical cost savings the details become more important.

Within a normal range of common rebar sizes, the material cost of the steel does not vary appreciably.

Changing the bar spacing will increase the cost of labor.

Adding additional fabrication to the rebar will increase and be compounded by the number of bars. This could also impact the timing. Both can increase the total cost.

Splices will increase the total tonnage and the labor cost because extra steel is used to transfer the loads (laps) from bar to bar.

If you get into the real costs to justify a change in the design, you need the details to come up with a theoretical savings. There are also the normal references that are used for cost estimating that are based on averages with not no details, but assumed percentages.

If you look very close in a review, you need details or a CPA, unless it is a small job.

on top of what Dick said, costs can also vary with the following:

the size of the job - larger jobs usually result in some cost savings over smaller jobs;

varies with the location - in the city may be cheaper due to more competition and skilled labor.

shipping the steel a long way may add to the cost;

Type of rebar - are you using standard rebar, welded wire mesh, pvc coated, z-bar?

 

[apriley]

If you're looking for a rough cost for typical rebar, our last job was bid at about 70 cents a pound (US). Since I believe the US dollar is slightly higher than the Canadian dollar, you can probably adjust it down slightly.

Interesting Dick.
Every single thing means cost, but what is the difference between 10M@10 Vs 15M@12 in terms of costing? the price per Kg will change wheather is 10M or 15M?. and if so, by how much?
Changing the spacing will increase the weight, and as the cost is per kg, the labour and material are increased by the amount the weight is increased; is it linear? maybe not, but how linear can one be with a rainy day? or a too hot day? that for sure will affect the cost of labour? Adding additional fabrication could affect more the cost, but how much fabrication can be added to a rebar? it is not a W beam with a cope cut. Laps are function of the weight.

Thanks Apriley, that's what I wanted to know!!!, just one question, does it include mat and labour? I mean roughly.
Thanks again Apriley, I am having an interesting conversation with the other guys, though!!

Antonio -

You are splitting the hairs too thin without any real information. Is this a top secret government job, a learning exercise or just a general analysis? - I recall the terms "approximately" and "roughly" being used.

The real engineering is an art that comes with the creation of the proper, constructable design using all the facts involved.

Two dollars a kilogram for material plus two dollars a kilogram for labour. That is a firm quote.

Come on guys, you are giving him a hard time for sure. The guy just wants a rough estimate, not a quote.

Antonio, there is a high variability on cost as it has been pointed out. Heavy bars are faster and cheaper to fabricate and install for the same weight (to a point). Slabs are esier to install than vertical pieces, bended pieces more expensive than straight ones. Distance to fabrication yard counts, more the size of the job, if it is a small job, transport eats a lot of the value and the delivery does not fill a truck, are there several suppliers competing with each other? is it a city or countryside job... all commnon sense stuff really.

Having said that, and with all the necessary disclaimers, a good conservative price would be up to 2 dollars per kilo, installed, that should give you an idea of the cost but I am not mistaken the cost should be below that.

I have heard steel will be going up but earlier this summer base pricing:

Black bar = $.35 USD /lb = .77 USD /kg
Epoxy bar = .50 USD / lb = 1.1 USD / kg

If its a large order and is purchased bundled reduce that by up to 25%.

This is pricing I have got for Upstate NY not including delivery.

I often use US$2 per pound for planning purposes for public works projects, considerably higher than VTEIT's number. However, I rarely estimate rebar cost, it is usually lumped in with cost of structural concrete except for very large structures such as bridges.

 

[Mixtli]

Dick, not a top secret job, but top my mind there's no need to provide more info than necessary. You recall good. What does that art thing have to do with this, lol?

Kelowna, thanks man. you started like the others, but then landed on a nice answer. Better yet, you called your fisrt paragraph a disclaimer, which is what everyone should do when talking engineering, cause nothing is written on solid rock, right?

So, guys, instead of asking a good amount of questions, why don't you just write your disclaimer and then contribute with your answer.

I worked on the estimation business for a number of years, and I know exactly what kind of factors influence the cost of rebar. I just don't know what is the price range these days!!!

Cvg, there you go, thanks...

fyi, deformed rebar costs around US$1300/tonne down here in Australia, the country without recession.

 

[Mixtli]

what do mean by deformed?, like when it's already in the final shape or form, like say a stirrup?

Is it so? that Australia had no recession? it was bad for Us here in Canada.
