Bidding Information for Contractors

Contractor Registration

Effective July 1, 1996, Montana law requires all contractors to register with the Montana Department of Labor and Industry. On Federal-aid projects, contractors must register prior to executing a contract. On State-funded projects, bidders must be registered prior to submitting a bid. For information regarding this requirement, contact the Department of Labor and Industry at 406-444-7734 or TTY 406-444-5549.


Prequalification is required only for some Specialty Types of work at this time. No other prequalification is required.

Contractor Identification (Vendor) Number

All bidders need a Contractor Identification (Vendor) Number issued through the Contract Plans Bureau to bid on a project using Expedite or Bid Express. To get a new number or find out what your existing number is call the Contract Plans Bureau at 406-444-6212, 406-444-6215 or 406-444-6216.

Expedite Software

All contractors are required to use the latest version of the Expedite software to prepare their bid electronically. This means the bid information is inserted into the program and saved to a disk or cd.

Bid Express is a second bidding option. Bid Express is an On-line bidding system that also uses the Expedite software. Bid Express is a service you will need to purchase thru to submit bids. The sign up process will take approximately 2 weeks. An electronic Bid Bond is recommended if submitting On-line bids.

When filling out your bid with the Expedite software please make sure the name of your company is correct and is the same on the schedule of items, proposal, and bid bond.

Bid Files

The Bid Files are electronic files that are used in conjunction with the Expedite software and contain all of the project bid items. The Bid Files can be downloaded from our web site for all projects. These files should be downloaded to a disk or CD to be turned in with the Hard Copy of the bid.
