Prime contractor prequalifications

The Iowa DOT is now requiring online submittal of the Contractor’s Financial-Experience-Equipment Statement (Form 650004). The Form 650004 must be completed and submitted online from a computer, tablet or mobile device. You will be able to upload attachments and submit them with the form. Any other submittal format is not accepted.

To be prequalified to bid as a prime contractor on most work types, a contractor must submit via online a Contractor’s Financial-Experience-Equipment Statement (Form 650004) for review by the Department at least five calendar days prior to the scheduled letting date. Previously approved statements expire 18 calendar months from your financial year-end listed on the statement.

A current version of the Contractor’s Financial-Experience-Equipment Statement can be found by doing a search for Form 650004 in the Iowa DOT forms portal.

Please direct questions to DOT.Contracts@iowadot.us.

Effective with the January 20, 2021 project letting, some changes have been made to the Contractor’s Financial-Experience-Equipment Statement (Form 650004).

For a Compiled/Individually Prepared Statement, the maximum prequalification amount has increased from $200,000 to $400,000.
For a CPA Reviewed Statement, the maximum prequalification limit for an individual proposal has increased from $1,000,000 to $2,000,000.
The Authorization To Loan limit has increased from $500,000 to $1,000,000.
