NIGP Codes for Design and Construction Contract Solicitations

NIGP Codes 

Facilities and Business Services Administration, Design and Construction Division

All searches and notifications on Buy4Michigan are based on National Institute of Government Purchasing (NIGP) codes. It is important that all Professional Services Contractors (PSCs) developing bid documents for the State of Michigan identify the appropriate codes for their projects to maximize participation and all suppliers and construction contractors understand the codes the State will be using to ensure they are aware of all solicitations in their area of expertise.

To assist PSCs, vendors, and construction contractors, the State has reviewed the entire NIGP listing and created a tailored listing of the NIGP codes we anticipate will be used on the majority of our projects. This does not prevent the use of other codes, however, we feel most of our projects will fit into these codes. This tailored list of codes is attached. Should a project require a service code not found here, please discuss this with your project director.  


As an example, a roofing project could use "90922 Building Construction Non-Residential" as the general code with "91066 Roofing, Gutters and Downspout Maintenance and Repair" and "91473 Roofing and Siding" as the specific codes.
