Chapter 6 Requesting Pay Items

Caution: Read the rules!

Great for utility items

Complete rules in Chapter 6. Here is a brief summary of the rules:

Must not be used if there is an existing pay item. Must not be used to violate or circumvent standard pay items. Must not be used to circumvent the approval process on developmental items. (No “testing” without Product Evaluation or Materials Office involvement) Must not be used as a work-around for a pay item that has been rejected for statewide usage by Central Office. Must not to be used for sole-sourcing of materials/ methods for items of work.

Generic Pay Items

Complete rules in Chapter 6. Good Examples:

Utility Items without existing pay items“Single use, Unique work”- Skyway lighting“Unusual”- boat dock

Remember:No tracking, no project or cost historyNo applicable specs/standards
