Confirmed Bidder’s Lists

We receive many questions on a regular basis related to bidder’s lists. Today, some of the most common questions regarding bidder’s lists will be answered in this article. How bidder’s lists are created and verified will be explained as well as the difference between a plan holder’s list and a bidder’s list.

One question that we get asked on a regular basis is, “Why are you calling me to confirm my interest in a particular project?”  Who does this help and how does this help them? Our process of compiling a list and calling to confirm interested bidders helps virtually everyone interested in the project. Sure, it is helpful to member companies, but it can also be helpful to non-member companies as well.
