LACK of rebar support
LACK of rebar support
(OP)
What are the standards for placing rebar support chairs for a driveway in a commercial construction application. I am asking because I have evidence that the contractor ran out of chairs and went forward with the pour because of major pressure from the construction manager. I represent the client, but before I escalate this issue I need to make sure I am right. I have attached a picture that shows a worst case scenario.

However, ACI-318 gives no minimum support spacing; the code gives the required clear-cover. Thus the number of required support chairs is the number needed to support the rebar at the required clear-cover. The code doesn't care if it's one support chair or 1000 support chairs.
