Architect, Engineer and Construction Business Directory Help

The directory includes both diverse and non-diverse owned businesses. It is comprised from many sources, including a large portion of WashU’s current businesses (identified as a “Yes” under “WashU Supplier?” in the results box), business included on WashU’s Master Contractor List, businesses who have a relationship with other regional anchors, current and prospective business who have registered on WashU’s supplier registration portal, and businesses from 3rd party resources, such as Reference Solutions.  

Information is updated on an on-going basis. If possible, new suppliers are added monthly. 

Each box contains a small eraser that allows for that specific selection to be cleared/reset. The entire page can be cleared/reset by clicking the button, near the end of the page. 

Disclaimer – This tool should be used as a resource to find businesses.  Additional fact finding will be necessary to determine if a supplier listed in the directory meets specific requirements. Please contact the Resource Management department if help is needed in this area.
