What the source says

ILLINOIS Amount of Bond: Shall be fixed by such officials, boards, commissions, commissioners or agents awarding the contract in an amount sufficient to complete the contract including the payment for all labor and material whether by subcontractor or otherwise. Labor and Material Covered: Material used in such work and for all labor performed in such work, whether by subcontractor or otherwise. In addition the Public-Private Partnerships for Transportation Act grants the Illinois Department of Transportation (IDOT) and the Illinois State Highway Tollway Authority the necessary powers for the development, financing, and operation of transportation projects through public-private agreements with one or more private entities. Bid, performance and payment bonds or other security determined suitable by IDOT, including letters of credit, are required. Notice Required: Every person furnishing material or performing labor, either as an individual or as a subcontractor for any contractor with the state or any political subdivision thereof, has a right to sue on the bond provided, however, that any person having a claim for labor or material as aforesaid shall have no such right of action unless he shall have filed verified notice of claim with the officer, board, bureau or department awarding the contract within 180 days after the date of the last item of work or the furnishing of the last item of materials and files a copy of the notice with the contractor within 10 days after filing the notice with the agency officer or political body clerk or secretary awarding the contract. The claim shall be verified and shall contain: (1) the name and address of the claimant; the business address of the claimant within the State of Illinois, and if the claimant be a foreign corporation having no place of business within the State of Illinois, the notice shall state the principal place of business of said corporation, and in the case of a partnership the notice shall state the name and residence of each of the partners; (2) the name of the contractor for the government; (3) the name of the person, firm or corporation by whom the claimant was employed or to whom he or it furnished materials; (4) a brief description of public improvement sufficient for identification; and (5) a description of the claimant’s contract as it pertains to the public improvement, describing the work done by claimant and stating the total amount due and unpaid as of the date of the verified notice. Time for Suit: No action shall be brought on the bond later than one year after the date of the furnishing of the last item of work or materials by the claimant. Public Improvement Lien: Illinois provides a lien on unexpended funds due the contractor. To preserve the lien, written notice of the potential claim must be sent to the public authority and contractor prior to the payment of the unexpended funds. Notice must be provided to the clerk or secretary, as the case may be, of the local government unit. A prime contractor can force a subcontractor to file its claim for lien by giving notice to subcontractor and if the subcontractor fails to file its lien claim within 30 days of notice, the lien is forfeited, otherwise suit must be filed within 90 days after filing the notice of claim. The suit must make the prime contractor and any intermediate subcontractors defendants. Notice of the suit must be received by the public authority within 10 days of filing. On state jobs, the suit must be filed not less than 15 days before the date on which the appropriation will lapse. Contract Bond Excluded: Under $50,000 for work performed for the State, and for all other political subdivisions under $5,000. A political subdivision may allow an irrevocable bank letter of credit in lieu of a bond on contracts under $100,000 if motor fuel tax funds, federal-aid funds or funds from the state are not used. Penalty for Failure to Take Bond: No special statutory provision. Statutory Citation: Illinois Compiled Statutes, 30 ILCS 550/0.01 to 550/3.
