Indirect Assessment Leads to Better Planning for Condition Assessment

In 2020, the city of Corpus Christi moved forward with a condition assessment project examining a series of underwater crossings and a portion of steel waterline. Through this work, indirect corrosion surveys were used to get a better understanding of the exterior condition of the pipeline. The city has used this study, and others like it, to better plan for future condition assessment projects as part of its asset management program. Based on the results from the initial study, other studies have begun, and the city has almost doubled the future budgets for assessment and rehab. The asset management program has resulted in moving toward an indefinite delivery indefinite quantity (IDIQ) contract for providing support to effectively use condition assessment funds where needed for in-depth study of the complete asset condition. This paper will discuss the indirect assessment methodology and results, how this information has been used to further the city’s asset management, and how it has impacted planning for future assessment and rehabilitation funds.
