IL SB2189

Requires the Illinois Department of Transportation to make advance payments to consultants for preparatory work, initial personnel, equipment, supplies, and incidentals before projects begin.

Sets the advance payment amount at 10% of the total contract value, to be paid 14 days prior to the consultant starting work.

Specifies that the advance payment is not additional compensation but rather an advance on the total contract amount, with the 10% deducted from future progress payments or the final contract amount.

Takes effect immediately upon becoming law.
