Contractors cannot produce comparable proposals if they receive different information. One may price a basic covering replacement while another includes drainage correction or equipment coordination. A shared project description reduces avoidable ambiguity.
What to do next
Provide the same records, access information, and requested outcomes to each bidder. Ask them to identify deviations explicitly. Compare those differences before comparing price so a broader recommendation is not mistaken for an unexplained premium.
