To ensure you receive timely notifications of all amendments and updates to this posting, we strongly encourage all interested parties to use the "Follow" feature within SAM.gov. To do so:

1. Log in to your SAM.gov account.

Why this is important:

• Notification: Once you follow this notice, SAM.gov will automatically send an email to your account whenever it is amended or updated.


• Correct Links: Each update to a SAM.gov posting generates a new, unique web link. Bookmarking a page or using an old link will take you to an outdated version. The email notification you receive from following the notice will always contain a direct link to the latest version.


• Verification: The upper right corner of a posting shows a "Version" box, however it always displays "Current Record" regardless of what version you are viewing. You must manually check the version dates using the dropdown and select the latest. Following a posting and using the emailed link ensures you are viewing the latest version and avoids having to manually verify.
