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
