General Contractor
This page lists all the steps for subcontractors needed to work with Black & Veatch. This includes how to get paid, the subcontractor prequalification process, finding open bidding opportunities, and the forms you should send on the job.
They almost always pay on time, the only problem is- if there is an issue with an invoice you've sent in, their AP department will not tell you and when it becomes passed due, it is EXTREMELY hard to get them to answer an email about what happened. It takes higher up project managers to finally get responses from that department.
