"I encountered a problem on my last project while working with a civil engineering firm we had hired. The plans had gone through the planning department and were approved. Our crew had installed the rebar for the foundation according to the engineer's rebar schedule, and when the inspector came out, the work did not pass inspection because the rebar schedule was incorrect. I had to have the civil engineer come out and redo the rebar schedule to pass the inspection. The engineering firm said that we would have to pay extra to draw up new plans, but I insisted this was their mistake and therefore they would have to pay. In the end, they drew up the correct rebar schedule at no charge, and the project passed the next inspection."

When describing the problem you encountered with an outside firm, avoid speaking negatively of anyone involved. When you talk negatively about others, it shows that you may not have the character and morals the company is looking for in a Construction Manager.
