Equipment not stocked in the general warehouse can be obtained through either a small purchase or a blanket order. The small purchase is most useful and practical for infrequently purchased items (items purchased once or twice a year). Three bids are required for small purchases over $5,000, unless a sole source purchase justification is submitted to the Procurement Division (PRO). Purchases of equipment over $25,000 are handled as an Open Market purchase by the Comptroller of Public Accounts (CPA).
