You expect support to be a given for software you use every day. Especially one as vital to your team’s success as your estimating software. MC2 is so old, support and updates don't exist. Don’t you want software that grows with you in your current projects?
If your preconstruction software is MC2, then you're probably feeling left behind. Consider the benefits your team gains by having a tool that is constantly improving, like DESTINI Estimator.
