At its own discretion, the Work Team may also consider Alternative Technical Concepts (ATCs). An ATC is a suggestion from a bidder that a different technical concept from that required by the draft RFP may provide greater benefit to the Kingdom (for example, that constructing a facility with 20 percent greater capacity would reduce the unit cost of output to the Kingdom). If the Work Team believes that an ATC suggestion has merit, the RFP may be amended to reflect this suggestion. However, in this event, the Third File and all associated information shall be updated to reflect the revised project concept and shall be submitted to the Supervisory Committee for review and approval with the Final RFP.
