DART – Let's Go.

Doing Business with DART


Large Purchases
Goods or services requirements greater than $50,000 require competitive bids or proposals. Large purchases are formally advertised by notices in the media, broadcast on the DART web page at, and distributed via notices to appropriate firms in DART's vendor database.

The two basic methods of procurement used for large purchases are Invitation for Bids (IFB) and Request for Proposals (RFP).

For IFBs and RFPs, DART awards contracts to the vendor who demonstrates the capacity and willingness to perform (e.g., proper equipment, manpower, financial resources, technical know-how, etc.) An award is made to the responsive and responsible vendor.

The solicitation is provided to interested vendors. The document includes a detailed purchase description and/or statement of work, contractual terms and conditions, and instructions on how to submit an offer to DART.

For each solicitation issued, DART assigns a Contracts Specialist as primary point of contact to assist vendors. In addition, a conference is generally scheduled well in advance of the bid/proposal submission deadline so that vendors can visit and obtain clarifications from DART.

Small Purchases

Goods or services less than $50,000 are purchased using DART's Small Purchase procedures (purchase orders). A purchase order is awarded if the price offered is determined to be fair and reasonable, and the vendor can meet delivery.
