Cost of concrete and reinforcement
Cost of concrete and reinforcement
(OP)
For an acedemic exercise I would like to get an idea of the relative cost of concrete and reinforcing steel in different countries. Could you give me an approximate cost for:
Concrete delivered and placed. $/m3
28 day cylinder strengths 32,40,50 and 60 MPa or closest equivalent.
Steel reinforcing bar cut, bent, delivered and fixed. $/tonne
Yield strength 500 MPa or closest equivalent.
16mm or less diameter
20mm or greter diameter.
If you don't know the exchange rate the local currency will be fine. Just let me know the country and the currency.
I'm just looking for ball-park figures, and the relative cost of concrete to steel is the important thing.
Thanks in advance.

RE: Cost of concrete and reinforcement
20 - 40 MPa Concrete (Type 10, Low Alkali S.F. blend)
Horizontal Concrete, Slabs, Bridge Decks, etc. $500/m3
Vertical Concrete, Walls, Piers, etc. $400/m3
Large Pours, Footings, etc. $350/m3
Includes forming, rebar placement, casting, finishing, curing, stripping.
Grade 400 deformed Bar (400MPa)
All Sizes: $2.25/kg (cut, bent, delivered, etc.)
Assumes that transportion is within say 50 km of fabrication/batching location(s) and would likely increase concrete costs by ~10% for 40 & 50 MPa strengths. I would stick with the figures above for <30MPa as well.
RE: Cost of concrete and reinforcement
All figures for "in-place" product so transportation, pumping, mixing, etc is included.
RE: Cost of concrete and reinforcement
KLF - based on your repiles, would $225/m3 be reasonable for concrete only (without forming or reinforcement)?
Qshake - concrete sounds expensive, did that include formwork and/or reinforcement?
Any numbers for the extra cost of higher strength concrete? It must cost something.

RE: Cost of concrete and reinforcement
We have done tenders in the past where the total cement is a bid item ($/kg cement). Contractors would play funny games with this item and I think its more or less dissappeared from use, in this area anyway.
I just went back through some of my older tenders and found these highest & lowest unit values from successful contractor's (low-bidder's) values:
the lowest bid value (footing): $99/m3
the highest bid value (bridge deck): $700/m3
