SUMMARY OF CHANGES

SECTION 00 10 00 - SOLICITATION

The required response date/time has changed from 18-Aug-2020 02:00 PM to 24-Aug-2020 02:00 PM.

SECTION 00 21 00 - INSTRUCTIONS

The following have been modified:

DOD SAFE INSTRUCTIONS

The Offeror’s bid shall be submitted electronically, as described below. The Offeror’s bid shall not contain classified data. The use of hyperlinks in bids is prohibited.

NOTE: The only authorized transmission method for bids in response to this solicitation is electronically via SAFE online submission. NO OTHER TRANSMISSION METHODS (EMAIL, FACSIMILE, REGULAR MAIL, HAND

CARRIED, ETC.) WILL BE ACCEPTED.

The Offeror’s bid must be received by the Government by the date/time specified in the solicitation.

Offerors shall electronically submit their bids using the following link:

h ttps://safe.apps.mil/

Within SAFE, please send bids to both Contract Specialist Ashley Stewart at ashley.l.stewart@usace.army.mil and to Contracting Officer Rosalind Shoemaker at rosalind.m.shoemaker@usace.army.mil.

Failure to properly submit a bid by the time due will render it late, and late bids will not be read. As this is an electronic submission subject to internet connectivity and other potential network traffic issues, offerors are cautioned to plan accordingly.

INSTRUCTIONS FOR SUBMITTING ELECTRONIC BIDS: In effort to reduce paperwork and cost, all bids shall be submitted electronically through the SAFE site. Submission shall be in Adobe PDF format. You are limited to five (5) maximum files per upload (total size cannot exceed 2GB). If you have a large number of files, recommend that you combine or ZIP your files before uploading to the SAFE site. Offerors may use compression utility software such as WinZip or PKZip to reduce file size and facilitate transmission.

REQUEST FOR UPLOAD CODE: In order to electronically submit a bid through DoD SAFE, offerors must email Contract Specialist Ashley Stewart at ashley.l.stewart@usace.army.mil and to Contracting Officer Rosalind Shoemaker at rosalind.m.shoemaker@usace.army.mil no later than five (5) working days prior to the bid due date to receive a request code which will allow for file uploads via the SAFE site.

Offerors that fail to email to request a code no later than five (5) working days before bid submission date may not be able to receive a request code in time to upload their submission.

FILE DESCRIPTION: Include a “File Description” for each file(s) you upload. The “File Description” will be included in the email notice to each of the recipients you choose to have access your file(s).

NOTE: Do NOT enter Privacy Act Data (Personal Identification Information (PII)) in the File Description.)

Submission shall be in Adobe PDF format.

INSTRUCTIONS TO FOLLOW ON THE SAFE WEBSITE: Once at the SAFE website select the “Drop-off” icon. This allows users without a CAC or users whose computer is not configured to read a Common Access Card (CAC) the option to access the SAFE site as a guest.

After selecting the “Click Here” link you will be prompted to add your personal information, file information, recipient (Government representative) information and email settings.

When completing your file information for transmittal via the SAFE website, you will be required to enter the email address for all recipients. For this solicitation, the recipients are the Contract Specialist and the Contracting Officer.

The email address for the Contract Specialist for this solicitation is ashley.l.stewart@usace.army.mil AND the Contracting Officer is r osalind.m.shoemaker@usace.army.mil. The E-Mail address of the Government Employee who initiated the request code will be automatically entered. The Offeror must enter the E-Mail address for both the Contracting Officer and Specialist. The Offeror can enter an additional E-Mail address if desired. After entering the email address, click the ADD button to add the person(s) email to the “Recipients List” of your response. When your bid is submitted, a notification will be sent to the recipients you added.

NOTE: Do NOT send the SAFE site packages to group email accounts.

Even if you successfully upload your bid to the SAFE site, notification will not be sent to the government recipients until you verify your email address. Entering an incorrect email may result in the rejection of your submission for lateness. An Offeror can confirm proper submission by the ‘Drop-Off Completed” screen which generates based on proper file submission.

NOTE: It has been reported that documents are more quickly uploaded into the SAFE website when using a Firefox web browser. The Government cannot verify that this is true and offers no guarantee that Offerors will have more success utilizing any particular browser.

RECEIPT OF SUBMISSIONS:

For the purposes of establishing whether a bid submission is considered timely, the government considers the date and time the submission is completely uploaded into the SAFE website. For bids larger than the 2GB capacity of the SAFE website and require multiple submissions, the Government will consider the date and time the last submission is completely uploaded into the SAFE website. Do not assume that electronic communication is instantaneous. It can take several minutes or even hours in some cases.

The government will not be responsible for submissions delivered to any location or to anyone other than those designated to receive bids. Offerors are responsible for ensuring that bids are submitted so as to reach the designated recipient. Offerors are responsible for allowing sufficient time for the bid to be received in accordance with the instructions provided.

Because uploaded documents expire in DoD SAFE, the submission of bids should only occur during a limited window of time from 1200 (noon) on 12 August 2020 17 August 2020 to the due date, in order to ensure that the submitted bids don’t expire before the bid opening officer has time to download the bids and conduct the bid opening.

Offerors are responsible for ensuring that they submit the submitted bid does not expire prior to bid opening on Monday, 18 August 2020 2:00 PM Monday, 24 August 2020 2:00PM
