Oregon Revised Statutes Public Facilities, Contracting and Insurance § 279C.412

(1) A public improvement contract estimated by the contracting agency not to exceed $100,000 may be awarded in accordance with intermediate procurement procedures for competitive quotes established by rules adopted under ORS 279A.065. A contract awarded under this section may be amended to exceed $100,000 only in accordance with rules adopted under ORS 279A.065.

(2) A procurement may not be artificially divided or fragmented so as to constitute an intermediate procurement under this section or to circumvent competitive bidding requirements under this chapter.

(3) Intermediate procurements under this section need not be made through competitive bidding. However, nothing in this section may be construed as prohibiting a contracting agency from conducting a procurement that does not exceed $100,000 under competitive bidding procedures.
