• Abstract:
  The overall objective of the research was to develop a pilot scale Culvert Information Management System (CIMS) that will ; comply with both requirements stipulated by the Governmental Accounting Standards Board (GASB-34) and new federal ; storm water regulations. A framework for inspection and rehabilitation/replacement of corrugated steel culvert pipes (culverts) ; is developed, and this report will form the basis for the creation of a computerized CIMS. The justification of the development ; of the CIMS is based on recent GASB-34 requirements. The CIMS will serve as a vehicle for evaluating underground ; infrastructure assets, specifically culverts, and facilitate computing present worth and comparing present costs of preserving ; them. Benefits of the CIMS will include long-term savings that should accrue from adopting optimized preventive ; maintenance strategies. ; The Condition States of culverts are used to express the extent of their deterioration. Different rehabilitation options are ; discussed and recommendations are made for deteriorated culverts. These options that will be incorporated into the CIMS, ; use survival probabilities based on the condition state of culverts. The survival probabilities for being in Condition States 1, 2, ; 3 or 4 are computed based on minimal field data. However, the CIMS requires additional field data for culverts or laboratory ; tests that mimic field conditions to enhance this capability. ; The CIMS is capable of analyzing decisions to inspect, rehabilitate/replace or do nothing at both project and network levels. ; At the project level this is achieved by comparing inspection and/or rehabilitation/replacement costs with risks and costs ; associated with failure. At the network level, the associated costs are optimized to meet annual maintenance budget ; allocations by prioritizing culverts needing inspection and rehabilitation/replacement. ; The CIMS consist of three major computer software components: databases, user interfaces, and a data administration ; module. Secondary components include an inlet/outlet structures module and a culvert segments module. The inlet/outlet ; structures module will store all the storm water data such as the quality/quantity of water and the receiving and discharge ; watersheds. Users will be able to retrieve culvert and inlet/outlet information and generate reports via location and ; road/milepost for condition state and assets needing immediate repair. The CIMS will also do the following operations: ; • Maintain an up-to-date inventory of eligible infrastructure assets. ; • Perform condition assessments of eligible infrastructure assets at least every three years, using a replicable basis ; of measurement and measurement scale. ; • Summarize the results, noting any factors that may influence trends in the information reported. ; • Estimate yearly the annual amount needed to maintain and preserve the eligible infrastructure assets at or above a ; prescribed level.
