Any proposal or modification to proposal received at the location designated in the RFP after the time and date set for receipt of proposals shall be considered "late" unless it was received prior to the contract award and any of the following applies:
Any request for withdrawal or request for modification of an offer received after the time and date set for receipt of proposals is late.
A late proposal, late request for modification, or late request for withdrawal shall not be considered, except as provided in this section.
A late modification of a successful proposal which makes its terms more favorable to the District shall be considered at any time it is received and may be accepted.
A late proposal, late modification of offer, or late withdrawal of offer that is not considered shall be held unopened, unless opened for identification, until after award and then retained with unsuccessful offers.
If any information received electronically is unreadable, the contracting officer immediately shall notify the offeror and permit the offeror to resubmit the unreadable portion of the information. The method and time for resubmission shall be prescribed by the contracting officer after consultation with the offeror, and documented in the contract file.
