DISCLAIMER: While Multnomah County is extremely confident in the full functionality of this system, as a legal matter, notification services offered through the site are not guaranteed and users of the notification service are ultimately responsible for reviewing postings to the site. Multnomah County disclaims all liability for damages from use of this site or the information it contains.

INCLEMENT WEATHER/EMERGENCY SITUATIONS: In the event of inclement weather or emergency situations, electronic bid or proposal submission date and times will remain unchanged. For construction/transportation bids that require additional documentation after bid opening, those documents will be required by 10:00 am on the first business day after County closure or delays. Please refer to the Sourcing Event for updated information, if any, on the time for Bid/Proposal submission. 


For new suppliers who do not currently have access to MMP, you will need to complete an MMP Supplier Access Request Form. In order to allow the County sufficient time to review your request, the MMP Supplier Access Request form should be completed no fewer than 5 days prior to any Sourcing Event closing date you wish to participate in.
