NOTE: The following list provides guidelines for State Bridge Office Discovery Phase work. It is not intended to be all inclusive.

Traffic Accomodation (Determined by KDOT with Consultant input)

• State Route detour
• Local Route detour
• Sho-fly detour
• Offset alignment
• Traffic thru construction (staged construction)
• Special traffic "events" to avoid
• Conflicts with other State and/or local projects
• Accident Data

Geometrics

• Review Bridge SI&A data for functional obsolescence
• Consider width requirements for AADT, % Trucks, accident data, route continuity
• Consider vertical & horizontal clearances
• Consider bridge rail , modify or replacement options
• Estimate bridge width and approximate length needed

Structural

• Review Bridge SI&A data for structural condition
• Review Load Ratings
• Review Bridge Packet for maintenance problems
• Is a Bridge Deck Condition Report needed
• Repair, Rehabilitate or Replace
• Propose feasible scopes
• Select appropriate structure types to consider
• Select LL & deck protection, route continuity requirements (heavy industrial)
• Type of survey needed: Total replacement, substructure reused

Hydraulics

• Review Bridge SI&A data for scour, debris problems, and hydraulic adequacy.
• Review inspection files for Underwater Inspections, Scour Calculations
• Start Hydraulic Assessment Checklist (existing structure, drainage data, reports)
• Review FEMA Maps, Drainage Reports
• Type of hydraulic survey needed: Special study needed, typical bridge survey
• Contact District for historic highwater information

Report Summary

• Scope or scope options
• Estimate of TS&L
• Cost estimate or estimate range
• Type of field survey needed
• Other things which could affect the project

Additional Work (add to Discovery Phase)

• Historical Preservation considerations (if necessary)
• Hydraulic survery and study
• Structural Analysis: Rails, Superstructure, Substructure, Foundations
