Purchase Requisitions in the amount of $100,000 and above require Chancellor approval.

Purchase Requisitions in the amount of $500,000 and above require Presidential approval.

Purchase Requisitions in the amount of $1,000,000 and above require approval of the Board of Trustees, unless they are exempt by the Policies of the Board of Trustees 5C-3(c)(2).

Responsible Party Action


Prepares and submits Purchase Requisition and letter of justification. If sole source justification is requested, submits Sole Source Justification form also.

If utilizing Grant accounts, documents must be approved by Grant and Contract Accounting within the Office of Sponsored Projects Administration.

If utilizing Foundation accounts, documents must be approved by SIU Foundation.
Department should know that purchases over the Small Purchase Maximum require formal comparative pricing or sole source justification.

Department should provide sufficient specifications to permit development of an Invitation for Bid Quotation or Request for Proposal.

For sample letters of justification see Presidential Letter Requirements. (completed by Procurement Services)

Insurance Requirements for IFB/RFP:
Prior to sending the Purchase Requisition and Invitation for Bid/Request for Proposal to Procurement Services, please contact Risk Management to determine if insurance is required and what the limits should be. Any information obtained from Risk Management must be in writing and forwarded to Procurement Services with the Purchase Requisition and Invitation for Bid/Request for Proposal.

Department submits a listing of Suppliers that should receive a copy of the Invitation for Bid/Request for Proposal. Buyer, at their discretion, may solicit additional Suppliers. 

All requests over the Small Purchase Maximum must be advertised for a minimum of 15 days on the Illinois Procurement Bulletin. Department must plan purchases in consideration of the additional time that will be needed to process these transactions due to the advertising requirement.

Specifications submitted should not be proprietary or otherwise unduly restrictive. Specifications cannot be photocopied or otherwise identical reproductions or drafts prepared by a potential bidder. Failure to provide adequate specifications with a Purchase Requisition will cause additional delay in processing the transaction.

Intent to purchase on a sole source basis must be advertised on the Illinois Procurement Bulletin at least 15 days and a public hearing will be held in Springfield for input from any interested parties. 

Department must submit a Sole Source Justification form that is detailed and sufficient enough to withstand a challenge by others. A difference in price between potential Suppliers, in and of itself, is not justification for a sole source purchase.

Department should consider that if a challenge to a requested sole source procurement is found to be warranted, the purchase transaction may be withdrawn as a sole source and will be handled under an Invitation for Bid/Request for Proposal solicitation process resulting in further delay in completing the transaction.

Posting an intent to make a purchase, as a sole source on the Illinois Procurement Bulletin will provide increased exposure, which could result in a challenge of this method of selection by other Suppliers.
The Director of Procurement Services must approve all requests for sole source justification.

Note: Emergency Purchases on Purchase Requisitions more than the Small Purchase Maximum as required by the Illinois Procurement Code are permitted in case of:  threat to public health or safety, to protect against loss of or damage to State property; to prevent or minimize disruption in State services; or to ensure integrity of State records.
