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

Traffic Accommodation (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 and 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 high water 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 survey and study 
• Structural Analysis: Rails, Superstructure, Substructure, Foundations
