A complex flowchart and decision matrix, titled "EP-10 vs Alabama Buys Decision Matrix," helps users determine the appropriate procurement method for different goods and services related to highway infrastructure and maintenance. The flowchart begins by asking whether a purchase order is for equipment, materials, supplies, or services related to construction, maintenance, or right of way. If not, it goes to Alabama Buys, except for certain facility exclusions like rest areas or fuel stations. If yes, it proceeds to further questions. If the purchase is for equipment or repairs related to highways, it directs users to the "Purchase and Repairs of Equipment (PRE)" method on pages 3 and 4, which advises obtaining multiple quotes when possible. For road building materials, it directs users to the "Road Building Material (RBM)" method on pages 3 and 4, which provides an example of materials like dirt and gravel and advises obtaining multiple quotes. For supplies and services for maintenance and operation, it leads to five procurement methods: Transportation Invitation to BID on page 5, Transportation Special Procurement on page 6 (with an example of concrete and asphalt), Transportation Small Purchase on page 6, Transportation Sole Source on page 6, and Transportation Request for Proposals on page 5. A separate path also branches off for Transportation Emergency Procurements on page 7, which requires multiple quotes for emergencies. A note at the bottom indicates that referenced page numbers indicate where the detailed process for each method can be found.
