"After all it's there. If the EC does not have an existing contract, how do you tell the concrete guys to turn up a piece of rebar?" This is actually up to the GC to ensure that the rebar is made available to the EC. The way it is done here is they use a 36" "corner bar" snap tied to the #5 in the footer. This will come up in a block core which is knocked out for the EC and sprayed green so they won't pour it solid.
