Technological advances in data management have created opportunities for engineers to manage the life cycle of infrastructure assets. Previous initiatives funded by the FHWA and its partner state departments of transportation have outlined a framework for the development of a Bridge Deck Preservation Portal (BDPP). The BDPP framework provides a systematic approach for predicting changes to bridge deck service life by combining physical characteristics, condition assessments, and user preferences/constraints with the application of specific bridge deck maintenance actions. Phase 1 - Feasibility and Framework has been completed and is available in the Documents section below or at: https://iowadot.gov/bridge/special_projects/Bridge%20Deck%20Preservation%20Portal%20-%20Phase%201_FINAL%20Report.pdf. This pooled fund effort centers around Phase 2 - Development and focuses on developing a functioning bridge deck preservation portal to aid bridge owners and bridge engineers in data-driven decision making on bridge deck preservation treatments to optimize efficacy and life-cycle cost.

The objective of the BDPP development phase is to provide a cloud based web tool hosted on the InfoBridge website that meets, or exceeds, the engineering based functionality outlined in the previously mentioned BDPP Framework Report. The BDPP will standardize the bridge deck maintenance process by assisting engineers with the logical selection of maintenance actions. The BDPP will create a set of maintenance action scenarios based on cost effective bridge deck implemented at the most efficient point in the life cycle of individual assets and integrate a fully functional bridge deck preservation portal programmed in accordance with the framework developed in Phase 1 to be hosted on the FHWA LTBPP InfoBridge website (https://infobridge.fhwa.dot.gov/).

To accomplish these objectives, the scope encompasses the need to finalize, test and calibrate the algorithms proposed in the BDPP Framework Report and develop a source code for InfoBridge to create a web-based portal that can be hosted on the InfoBridge website. Specifically, the following tasks are envisioned to develop a fully functioning source code that can analyze multiple maintenance action plans and complete the described analyses by the proposed framework: Task 1. Develop a Fully-Functional Tool in a General Purpose Programming Language 1a) Parametric Study to Validate Reduction Factors and Estimated Service Life. 1b) Develop Database for Maintenance Actions 1c) Develop Filters & Thresholds Module 1d) Refine Reduction factors 1e) Develop Deferred Maintenance algorithms 1f) Develop the Automatically-Generated Maintenance Activity Plans Optimization Module Task 2. Development of the Web-Based Portal Task 3. Verify the Web-Based Portal Task 4. Beta Test Period Task 5. Bridge Deck Preservation Web Portal Manual Task 6. Distribute the Web Portal and Manual

FUNDING Requested minimum commitment total per partner is $60,000 in any combination utilizing FY21 through FY23 funding years. Funding includes $2,500 for one technical representative to attend two in-person meetings. Additional funding above the $480,000 threshold would allow for initial state-specific targeted results utilizing the BDPP. WAIVERS SPR Part II 100% waiver will be requested.
