Productivity Rate - Rebars

Hi Jim,

You can start by collecting actual data (manhours, daily erected tonnage, actual dates), After that you can prepare your actual productivity rates on site.
You have to indicate in your study whether the steel fixers formed the rebars on site or they only erected it.
In case that the steel fixers formed the steel and later on erected it, then you can have separate productivity rates for formation and erection.
You can also make a chart for the delivery of steel rebars to the site.
From your productivity rates, you can analyze the effect of weather, working in shifts, suppliers of steel rebars, ..etc on your project.

Thanks for your kind and professional suggestions.
You really help me to build up the basic concept for my project. But may I ask for one more favor.

Are there any journals or readings related to this topic?
Or
Are there any books related to this topic?

(I have searched a lot for this topic and found little on this topic)

Thanks alot!

Hi Jim,

Once we have had this post in PP (regarding the temperature effect on productivity rates):

Also if you want to find a site which offers productivity rates, then you can find that in: http://www.planningplanet.com/output_page.asp?choice=outputs and

Jim,

When you do your productivity studies, make clear what type of structure rebar is fixed to. Horizontal slabs are likely to have considerably higher productivity rates than vertical walls for example. Another distinction to make is rebar diameter – generally the larger the diameter the higher the productivity rate.
