Rebar mechanical splice - ballpark cost?

Rebar mechanical splice - ballpark cost?

Rebar mechanical splice - ballpark cost?

(OP)
Does anyone have a rule of thumb for this?  (something like 'a mechanical splice costs about the same as a XX diameter lap splice')

I've tried contacting splice vendors for cost info, but I'm really more interested in installed cost of a mechanical coupling compared to the installed cost of a lap.

Also, would anyone care to name a particular favorite brand of mechanical splice?

Thanks for your time.

In the electric power plant business, Cadweld Mechanical Splices are often considered to be "the best". (Our specifications would say something like "...Cadweld mechanical reinforcing steel splices, or equal..."

As for installation costs, at a time long ago - as a Contractor, assuming that installation cost equals material cost was usually a reasonable assumption (if we did not have better data). However this applies only to items of MINOR value in an overall project estimate - I would never do this as a significant part of bid preparation.

Just a thought, but some manufacturers have done time studies on their products and will give you a range of time in man-hours to install their product.  Ask and see if they can help you out.  It is a another place to start if you don't have your own cost data.

You have dollars per lb. vs. cost per coupler plus time - It will vary depending on size.  If you say one minute per coupler (at $1 each) at rodbuster price plus overhead of $60 per hour = $2 each.  If your average lap is 4 lbs and cost is $0.50 per lb, that would be about a wash (these are numbers I pulled out of ... the air).  

Check your lbs per splice - by bar size, and confirm the other info.  Coupler $ will also vary by size.

One caveat - some manufacturers will give optimistic prices so their products are purchased.

RE: Rebar mechanical splice - ballpark cost?

I have been working in the highway industry, mostly in bridge design, for the past seventeen years.  I don't recall ever hearing a Contractor asking to use a mechanical splice in leiu of a lap splice.  We use mechanical splices for rebar in several cases, so the Contractors are aware of them.  Given this, I would be shocked to hear it was more economical to use a mechanical splice.  Having said that, laps for #14 or #18 bars are very long, and the bars are very heavy.  We almost never use #14 or #18 bars for this reason.  I would use bundled #11s first.
