Proposed AASHTO Guide for Bridge Preservation Actions

Many transportation departments have significant practical experience with bridge preservation and have developed conclusions regarding the effectiveness of bridge preservation actions based on those experiences. However, limited efforts have been made to identify, measure, evaluate, and document the short- and long-term performance of specific bridge preservation actions. Bridge preservation consists of actions to deter or correct deterioration of a bridge to extend its useful (service) life and does not entail structural or operational improvements beyond the originally designed strength or capacity of the bridge. Often practitioners apply preservation strategies on the basis of judgment or common sense using available resources. However, it is difficult to translate these strategies into coherent and convincing arguments in the absence of a quantitative measurement of bridge preservation effectiveness. The objective of this research is to develop a bridge preservation guide for possible adoption by the American Association of State Highway and Transportation Officials (AASHTO). The proposed AASHTO guide shall be developed based on data to be collected from representative agencies. At the minimum, the guide shall include: (1) a catalog of bridge element preservation actions and (2) the criteria and selection methodology of bridge preservation actions with associated costs and benefits for use in life cycle cost analysis and possible integration into a bridge management system. Accomplishment of the project objective will require at least the following tasks: Proposers are asked to develop a detailed research plan for accomplishing the project objective. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers' current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objective. The work proposed for each phase must be divided into tasks and proposers must describe the work proposed in each task in detail. PHASE I - Planning: Task 1. Conduct a critical review of existing technical literature, pertinent international and domestic scans, the reports prepared under National Cooperative Highway Research Program (NCHRP) Project 14-23 (see Special Note A), and other NCHRP projects. In addition, the review should include owner and industry practices, the Federal Highway Administration (FHWA) Long Term Bridge Performance (LTBP) Program, and other research findings from both foreign and domestic sources. Task 2. Identify the required data to be collected in order to achieve the research objective and propose 8 agencies for data collection considering diverse service environments. The project panel will select at least 4 agencies for data collections under Phase II. Task 3. Prepare a list of bridge preservation actions to be developed under Phase II. Task 4. Prepare a detailed outline of proposed AASHTO guide. Task 5. Develop the data archiving and sharing plan as described in Special Note C. Task 6.Prepare Interim Report No. 1 that documents Tasks 1 through 5 of Phase I and provides an updated work plan for the remainder of the project no later than 3 months after contract award. The updated plan must describe the process and rationale for the work proposed for Phases II through IV Note: Following a 1-month review by the NCHRP, the research team will be required to meet with the project panel to discuss Interim Report No. 1, if necessary. Work on Phases II through IV of the project will not begin until authorized by the NCHRP. Phase I shall be limited to $15,000. PHASE II - Catalog of Bridge Preservation Actions: Task 7. Collect and perform data mining to achieve the research objective. Information from agencies should be augmented by documented research. Task 8. Develop the catalog of bridge preservation actions focusing on the bridge elements that significantly impact the bridge service life (e.g., bridge deck, joints, coated steel, etc.). At a minimum, the catalog shall include: action type; material; description; cost; and how long the action lasts and when it should be applied based on condition. Task 9. Propose a method, for further analysis in Phase III, to establish <span>the criteria and selection methodology of bridge preservation actions using life cycle cost analysis with supporting examples. Task 10. Prepare an annotated description of each section and subsection of the proposed guide along with the expected level of detail of each subsection. Task 11. Prepare Interim Report No. 2 that documents Tasks 7 through 10 of Phase II and provides an updated work plan for the remainder of the project no later than 6 months after Phase I approval. The updated plan must describe the process and rationale for the work proposed for Phases III through IV. Note: The contractor shall meet with the project panel 1 month after submission of Phase II deliverables. Work on Phase III of the project will not begin until Interim Report No. 2 is approved and the work plan is authorized by the NCHRP. Phase II shall be limited to $85,000. PHASE III - Draft Guide for Bridge Preservation Actions: Task 12. Establish the analysis of the proposed method according to the approved Task 9. Task 13. Prepare the proposed AASHTO guide based on the outcome of previous tasks Task 14. Prepare Interim Report No. 3 that documents the result of Tasks 12 and 13 no later than 8 months after approval of Phase II. Note: Work on Phase IV of the project will not begin until authorized by the NCHRP. PHASE IV - Final Products: Task 15. Update the proposed AASHTO guide after consideration of review comments. Task 16. Prepare a final report that documents the entire research effort. Note: Phases III through IV shall be limited to $200,000. Following receipt of the draft final report, the remaining 3 months shall be for NCHRP review and comment and for research agency response and preparation of the revised final report. SPECIAL NOTES: The agency final deliverables (final report, handbook sections, and Appendix E) prepared under NCHRP Project 14-23 contain information on possible <span>bridge preservation actions. Proposers are encouraged to review these materials and, if appropriate, to consider the described bridge preservation actions as a basis for the bridge preservation actions that will be developed in this research. A. The agency final deliverables are available at: B. The research team should anticipate making two presentations to appropriate AASHTO technical committees of the AASHTO Highway Subcommittees. C. To ensure that data produced under this project are accessible, a data archiving and sharing plan shall be prepared by the agency performing research. The plan must be submitted in Phase I and shall include a description of expected activities, schedules, limitations, milestones, and required resources. Researchers should describe briefly the expected schedule for data production and archiving in the NCHRP permanent repository, the format of the final dataset, the documentation to be provided, and whether or not any analytic tools and/or results also will be provided. The plan must include a description of actions planned to ensure quality. Moreover, the plan must specify the resources required to archive and distribute the data expected to be obtained in the course of performing the research. In general, public release of data will not occur before full review and approval by the NCHRP project panel. The data archiving and sharing plan must include the following sections: (1) Background and significance
