How to Become a MoDOT Vendor for the Purpose of Obtaining Plans

MoDOT project plans can be accessed electronically using MoDOT's plansroom.

Plans can be viewed online by anyone. To download plans requires MoDOT vendor access to the plansroom system. Please see below for information on how to receive a vendor number.

Prime Contractor:

All contractors bidding on MoDOT construction projects must be prequalified to bid before any bid is accepted from them.  During the prequalification process a vendor number is assigned and can be used to access letting information.  Please follow this link for more information on becoming  prequalified to bid and obtaining a prime contractor vendor ID.


When a prime contractor selects a subcontractor to work for them, the subcontractor must register with MoDOT before they can work on our right-of-way.  A vendor number is assigned during registration.  Please follow this link for more information on registering as a subcontractor. 

Not a Prime Contractor or Subcontractor, But Still Want to Download Plans?

The plansroom system that allows access to download plans requires a vendor number.  If an entity has not received a vendor number by performing  contracting work with MoDOT, a vendor number can be issued for the sole purpose of accessing the plans.  Please see the section below for more information. 

The following information is required to be assigned a MoDOT vendor number:

Name, address, e-mail address, and phone number.

After submitting this information, you will be assigned a vendor number.  Once a vendor number is assigned, the new vendor will have full access to download letting information by the following morning.
