Cost of Reinforced Concrete Columns
Cost of Reinforced Concrete Columns
(OP)
Hi guys,
I have a situation where some isolated 800 x 300 reinforced concrete columns (2.5' x 1') have been offset from the gridline. There are no architectural requirements to have these columns this dimension at this particular location, so I was wondering if it would be more economical to provide a 400 x 400 (1.25' x 1.25') square column in this location if it is easier to form and build and therefore, reduce cost.
What is the contibuting factor to the cost of reinforced concrete columns, should I call up all columns the same dimension for the re-use of forms or would reducing the material used be more economical?

RE: Cost of Reinforced Concrete Columns
I think what you are hinting at is also true to an extent...that odd shaped rectangular column forms are more expensive than square column forms which many times are formed with standard form systems...but I think that some form systems are fairly versatile.
