A sealed bid is a supplier submission that remains inaccessible to the evaluation team and other bidders until the closing deadline and formal opening. The method is intended to limit information leakage and unequal revisions, but fairness still depends on clear specifications, secure handling and documented evaluation.
How does a sealed-bid process work?
The buyer issues common instructions, receives bids through a controlled channel, locks access until close, records the opening and evaluates only eligible submissions against the stated criteria.
When is it appropriate?
It suits requirements that can be specified clearly and compared on predetermined commercial and technical criteria. It is less suitable when the solution must be developed collaboratively through dialogue.
What controls preserve integrity?
Use a single deadline, tamper-evident or access-controlled storage, named opening participants, conflict declarations, version control and a record of late or withdrawn bids.
Can bidders clarify or revise?
Clarifications should explain an existing submission without allowing an unequal material change. If the process permits revised offers or a best-and-final round, apply the same rules and opportunity to eligible bidders.
What should the award record show?
Keep the solicitation, bidder communications, bid receipt and opening log, evaluation evidence, approvals, disqualification reasons and final award notice.
