Project Development Workflow Tasks (PDWT)
II. Project Initiation Document
A. Define Transportation Need and Assess Site (150.05) - Obtain and Review Existing Reports, Studies and Mapping (150.05.05)
The Office of Structure Maintenance and Investigations (OSMI) is responsible for managing the Department's highway structures. This includes performing bridge inspections, making structure work repair recommendations, and determining the safe load capacity of all bridges,
The OSMI maintains several reports containing information on the condition and rehabilitation needs of bridges and box culverts. The Structure Replacement and Improvement Needs report (STRAIN) and the Sufficiency Rating report are two primary sources of information that the project engineer should review. Both of these reports may be accessed on-line through the Office of Structures Maintenance and Investigation website.
The STRAIN report contains recommended improvements to structures. Such recommendations by OSMI may include; bridge rail replacement or upgrade, scour mitigation, deck rehabilitation, seismic retrofit, painting, column rehabilitation, footing rehabilitation, etc. The report may show cost estimates and other comments about the recommendations, and the report indicates if the recommended improvements are programmed.
The Sufficiency Rating report also contains information on bridges such as approach roadway width, bridge roadway width curb-to-curb, AADT, if compliance with current railing standards, the primary and secondary types of construction material, condition of the deck, superstructure, substructure or culvert, gross operating load rating, year of original construction, minimum vertical clearance, and more.
Even if there is no planned bridgework within the project limits, the project engineers should check both STRAIN and Sufficiency Rating reports for nearby bridges and box culverts. It may be appropriate to include bridge needs work into roadway rehabilitation projects. The project engineer must also be aware of any other bridge projects that may be underway so that duplication or conflicts are avoided. See Task P23 for further discussion regarding adjacent projects.
