You are contractor and there is confusion in the contract documents regarding structural requirements for the roof. The owner feels that you are obligated to provide a much more costly system than you bid and the architect agrees. This confusion has the potential of costing you your entire profit and you aren't about to give in. There are no requirements in the contract for exactly how the parties are to proceed; one option you have is to take the owner to court (to litigate.) Give two reasons why might you be reluctant to use litigation to resolve the problem. Explain.
