Well, you put us in a pickle. We do not know the ins and out of the job. It may be that he is attempting to make up for a low bid to begin with, or trying to pad the profit like you suggest. Or, it may be that he feels the labor cost really need to be that high. Aren't you getting other bids? Can you reject his bid and ask for new? Is it a problem of time? Extras are sometimes counted on to make a profit, as the job is bid with little or no profit. Ask the contractor about his bid, maybe he will explain, or maybe he will come down some. Usually, if you are open and honest with someone they will be the same with you.
