After evaluation of the price analysis, taking into consideration the schedule of estimated contract payments, the Owner may require that the amount of Contract Performance Guarantee be increased at the expense of the bidder to a level sufficient to protect the Corporation against financial loss in the event of default of the successful bidder under the Contract (3% of the Corporation’s cost estimate). 20.1.4 If a bid price appears to be unusually low in relation to the services to be rendered, the bidder will be requested to submit a written breakdown of his price calculation.
