General Contractor
This page lists all the steps for subcontractors needed to work with DDC Group. This includes how to get paid, the subcontractor prequalification process, finding open bidding opportunities, and the forms you should send on the job.
I am not sure about other reviews. We have been a subcontractor on 12 projects and always got paid on time. Maybe you didn't complete the scope? I know they are strict on schedule and completion. Either way yes they are we in Chapter 11 BK, most large companies were at some point.
