How many people today in the concrete contractor’s office can identify the exact mix that is needed by reading the specifications on the project in the bid stage, create the proper mix without overlooking the most important characteristics of the concrete and not overload it with unnecessary products?

How many people in the same office can pick up the phone and call the Design Engineer and ask the questions regarding the properties of concrete specified? 

Many ways concrete can be either enhanced by the pump operator, mason and the superintendent on the job, and can be wrecked by the same people. Keeping the concrete on the job for too long, adding more water than the mix requires, over finishing the slab, etc. can eventually make the contractor a liable party for non-conformance.

And, as long as we are on a conformance issue of concrete on the project, who evaluates the people that are inspecting and testing that concrete? I am confident to say, that there are far and few between people representing the contractor in the field in a professional matter, assuring the contractor that all regulations and codes are met.
