摘要：	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.
