Bidding time is the period of time between the date of notice or distribution of the Invitation for Bids and the time and date set for receipt of bids.

The conference may be designated as "attendance mandatory" or "attendance optional". The conference should be held long enough after the Invitation for Bids has been issued to allow bidders to become familiar with it, but sufficiently before bid opening to allow consideration of the conference results in preparing their bids. Nothing stated at the pre-bid conference shall change the Invitation for Bids unless a change is made by written modification to the Invitation for Bids. Amendments shall be supplied to all those prospective bidders known to have received an Invitation for Bids. If the conference is mandatory, the amendment shall be supplied to attendees only.
