ARTICLE 15. RECEIVING BIDS, MODIFICATIONS, OR WITHDRAWALS

Bids received prior to the time set for opening will be securely kept unopened. The officer whose duty is to open them will decide when the specified time has arrived and no bid received thereafter will be considered unless: (1) they are sent by registered mail or by certified mail for which an official dated post office stamp (post-mark) on the original Receipt for Certified Mail has been obtained and it is determined by the District that the late receipt was due solely to delay in the mails for which the bidder was not responsible; or (2) if submitted by mail (or by telegram if authorized by the Contracting Officer), it is determined by the District that the late receipt was due solely to mishandling by the District after receipt at the District agency: Provided, that timely receipt at such agency is established upon examination of an appropriate date or time stamp or other documentary evidence or receipt within the control of such agency.

Bidders using certified mail are cautioned to obtain a receipt for certified mail showing legible, dated postmark and to retain such receipt against the chance that it will be required as evidence that a late bid was timely mailed. The only evidence acceptable in this matter is as follows: (1) where the Receipt of Certified Mail identifies the post office station of mailing, evidence furnished by the bidder which established that the business day of the station ended at an earlier time, in which case of the time of mailing shall be deemed to be last minute of the business day; or (2) an entry in ink on the Receipt for Certified Mail showing the time of mailing and the initials of postal employee receiving the item and making the entry, with appropriate written verification of such entry from the post office station of mailing, in which case the time of mailing shall be the time shown in the entry. If the postmark on the original Receipt for Certified Mail does not show a date, the bid shall not be considered.

The time of mailing of late bids submitted by registered or certified mail shall be deemed to be the last minute of the date shown in the postmark on the registered mail receipt or registered mail wrapper or on the Receipt for Certified Mail unless the bidder furnishes evidence from the post office station of mailing which establishes an earlier time.
