Federal Highway AdministrationUS Transportation CollectionDrainage Identification, Analysis and Mapping System (DIAMS) is a computerized database that captures andstores relevant information associated with all aboveground and underground hydraulic structures belonging tothe New Jersey Department of Transportation (NJDOT). DIAMS retrieves relevant performance and financialinformation so that NJDOT can remain compliant with Phase II of the Government Accounting StandardsBoard Statement 34, which is NJDOT\ue2\u20ac\u2122s sole means of reporting all financial transactions, namely the value ofinfrastructure drainage assets on an accrual accounting basis. DIAMS also retrieves all relevant environmentalinformation to comply with the Clean Water Act and reporting requirements of the NJDEP. The DIAMScapabilities include identifying drainage infrastructure, maintaining inspection history, mapping locations,predicting service life based on the current condition states, and assessing present asset value. The DIAMSalso contains several different repair, rehabilitation and replacement options to remedy the drainageinfrastructure. In addition, the DIAMS can analyze asset information and determine decisions to inspect,rehabilitate, replace or do nothing at the project and network levels. Furthermore, the financial analysis modulewill output data into categories including inspection, cleaning, repair, and condition states. The process willdirect users and decision makers to evaluate work orders, which will be reported in summaries, allowing thebest choice for asset performance implementation for each asset type. Thus, making DIAMS an indispensableasset management and environmental information management tool.
