Envelopes must be rightfully marked as ORIGINAL or COPY. The Project Proponent's name and address must also be written to enable the LGU-PBAC to return the Bid unopened in case the Bid submission is declared late.
If the envelopes are not properly sealed and marked as instructed, the PBAC shall assume no responsibility for the misplacement or premature opening of the submitted Bid. A Bid which is opened prematurely for this cause will be rejected by the PBAC and returned to the Project Proponent.
