NBI Conversion:• On inspections• Check Classifications, particularly of ADE’s• Consider your target: by count or deck area• Dial in a small group, then compare to a larger one
• NBI Deterioration• Classification, again.• Again, small group, then compare to a larger one
• Risk Assessments• The types of Risk you need• Policies for Risk
• Work Candidates• Work entered by planners and inspectors• Action Types• Estimated Costs
• Utility• Don’t include AADT, do things which can improve• Including Risk assessments• Weight Profiles for just risk, just scour, just seismic, just preservation
• Elements• Get the elements you need for proper management, consider the
units and roll them up.• Element Relative weights and NBI relative weights
• Benefits• Name them for the effect, not the work• 100% effective can lead to infinite loops• NBI Deterioration
• Action Defs• Network Level actions• Indirect cost formulas• Syntax of formulas
• Project Categories• Make them your spending categories
• Funding sources• Less useful than originally envisioned, and you don’t have to use it.
• Network Policies • Name policies with a count of how many branches are included
• Lifecycle policies• Start simple, then complicate.
• Structure Weight Formula• AADT order of magnitude swing• Deck Area• New Mexico combined solution
• Min Proj cost• Programs
• LCCA time frames• Subdivision profiles

Where do I start?The New Jersey Method:
What questions am I trying to answer?
What kinds of programs do I need?
What funding will I need for those?What performance measures will I need?
How would I like my projects broken up?
What work do I want recommended?
What factors matter to my decisions?

Remember: include in Utility the things which can be improved from doing work. Detour length and AADT are rarely fixed by maintenance work.
But if you include a formula, like AADT/# of Lanes, then work can improve things.

Consider the units of your costs.Idaho preferred to set their per/unit costs based on bridge item bid costs. But the optimizer budgets are given in total program costs.
Consider using indirect formulas to mark up the difference.

Focus on the Bridge Replacement first.
Then replacement of culvert, deck, then super.
Deal with repair frequencies after, if your agency has firmly set policies for these.
