A constraint inventory is a systematic record of all route limitations, organized for reference and action.
Organization Options
Sequential (by route position)
- Ordered from origin to destination - Natural for following the route - Easy to use in the field
By Type
- Grouped by constraint category - Easy to assess overall constraint profile - Useful for resource planning
By Severity
- Critical constraints first - Focuses attention on key issues - Useful for go/no-go decisions
Data Fields for Each Constraint
Location
- GPS coordinates - Mile marker or route reference - Nearest landmark or cross-street
Identification
- Constraint type (clearance, weight, geometry) - Structure or feature name/number - Specific limitation
Measurement
- Quantified value where applicable - Measurement method noted - Uncertainty or variability noted
Status
- Constraint | Clear | Conditional - Mitigation required? - Mitigation in place?
Evidence
- Photo reference - Survey date - Surveyor identification
