30+ Years Providing Project Management Expertise

Since 1984, we have provided project management solutions to companies in the Engineering and Construction industries. We got our start as a Primavera solution provider, primarily guiding Contractors and Owners on using CPM scheduling tools to their advantage. In 2008, we recognized a need for our customers to work more collaboratively with their teams outside of their organizations like Architects, Engineers, and Subcontractors by sharing documents and streamlining construction processes like RFIs and Submittals. So, we created VPO.
