Chapter 5: Contact Lists
Consultants with Project Specific Issues
•Designer coordinates with Project Manager.•Project Manger works with District or Responsible Office, as needed
•E-mail, with Designer and Project Manager’s contact information, works well to expedite responses. Carefully select the “cc: group”•Project Number, Letting & Production Dates
Chapter 5: Contact Lists
Example Pay Item Groups•334- 1- AA Superpave Asphaltic Concrete, TN•700- 1- AB Single Post Sign, AS
Chapter 6 Pay Items
Opening pay items•Item structure is already in the BOE•Valid/Obsolete dates may apply•minutes-24 hours
Creating new pay items•Additional Size, shape, etc.•Other operations?•General use, new specs?•Project Specific/Limited use? •Developmental/Experimental?•minutes to several days, depending upon specs, standards, other coordination
Chapter 6: Requesting Pay Items
Open/New Pay Item RequestsNO FORM needed, just e-mail
Financial Project IDLetting datePay item number and descriptionCost data, if available
For commonly used items, a related pay item number is acceptable.Supplier/Manufacturer cost + installation

Chapter 6: Requesting Pay Items
Coordination Team•Representatives from Design, Construction, Maintenance, Traffic Ops, and other offices•Coordinate the implementation of Pay Items, Specifications, Standards, and other issues
Management Team•Managers from these offices•Resolve policy issues, set implementation dates/goals
Chapter 6: Requesting Pay Items
Generic Pay Items•Format 000-AAA-BBB, where •AAA = Design Groups /Category and •BBB= sequential numbering 1, 2, 3, etc.

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
Generic Pay Items
•Coordination between plans, specs, and pay items•Specifications Description MaterialsConstruction or Installation requirementsMethod of MeasurementBasis of Payment
•PlansLocationDimensions/quantity
Chapter 7: Design Tools
•Coordination between plans, specs, and pay items
Chapter 7: Design Tools
Specs: Book, SPs, TSPs, Developmental, Supplemental
Plans: Structures, Roadway, Lighting, Signals, etc.
Estimate: Item Number, Description, Units, Prices
Standards:E-book, IDS
Plan Notes should NOT be used to change, duplicate, or override the specifications or standards.
Chapter 7: Design Tools
Project Specific Details- good
Duplicating Specs- bad

Chapter 10: Formatting Pay Items
If you don’t see a pay item that you need, please ask.
•Existing/available Item groups•Request that an item be opened/activated, if needed•Request that we restore an old item/structure, if neededVerify that old specs/standards are applicable
•Request that we create a new item group•Consider requesting a Developmental Specification and Pay Item•Consider a Generic Pay Item
