Stage 2 - Selection of Accelerated Bridge Construction Projects Appropriately selected ABC alternatives can substantially reduce construction time, impacts to users, and improve safety. Alternatives should be considered very early in the scoping process (concurrent with the Bridge Scoping Worksheet) to allow for potential adjustments in letting date, project schedule, funding, design duration, and time needed for pre-fabrication of bridge elements. This tool should be used during the scoping process to determine whether the following bridge related issues are present or should be considered during project development. The more questions that have “Yes” or “Possibly” as answers, the more likely that accelerated bridge construction (ABC) techniques may provide a viable solution. This tool should be filled out and recorded by the District Project Manager, with assistance from the District Bridge Engineer, Traffic Engineer, Resident Engineer, and the Bridge Preliminary Plans Unit and Regional Bridge Construction Engineer. Refer to pages 3-6 of this document for additional instructions and guidance. Prepared By: Date: District: Additional Assistance Provided By: Project Information: Bridge No.: TH: Let Date: ADT On: ADT Under: Project Description (work type, major roadway work also required?, anticipated duration): Question/Issue Yes No Poss N/A Comments Is it likely that this project will include complex traffic control schemes, long detours, or significant user impacts due to bridge construction? Is it likely that this project will have an extended duration (more than one construction season, or extend into late fall) due to bridge construction? Is bridge construction on the critical path of this project? Are there any issues regarding construction timeframes (e.g. fish spawning, bird nesting, high water, permits, major events)? Are there critical features or services on the route that need to be considered (e.g. hospital, emergency services, transit, school buses)? Could additional width be needed on culverts, bridges, or shoulders to maintain traffic on the existing route or the detour route? Does the existing bridge have features that make it difficult to accommodate staging (truss bridge, slab span, beam spacing issues, etc.)? Is it likely that temporary bridge structures will be needed? Could there be a need to maintain railroad traffic?
