If you've finalized an Alternate Submission but would like to withdraw it, the steps to un-submit are similar to how you would un-submit your primary submission as outlined on our Can I un-submit my bid once it has been submitted and finalized? article.
Once you click on the Submissions page, you can view your Completed Submissions.
Your Alternate Submissions will show "Alternate #1", "Alternate #2", etc. next to your Vendor Organization name so you can easily identify them. Click on Actions then View, this will take you to the respective Submission Receipt.
You can then un-submit by clicking on Click here to un-submit your submission.
NOTE: You may only un-submit a submission so long as the project is still "Open" and the Project Closing date has not yet passed.
