Drainage Identification Analysis And Mapping, Phase 2

Drainage Identification, Analysis and Mapping System (DIAMS) is a computerized database that captures and stores relevant information associated with all aboveground and underground hydraulic structures belonging to the New Jersey Department of Transportation (NJDOT). DIAMS retrieves relevant performance and financial information so that NJDOT can remain compliant with Phase II of the Government Accounting Standards Board Statement 34, which is NJDOT’s sole means of reporting all financial transactions, namely the value of infrastructure drainage assets on an accrual accounting basis. DIAMS also retrieves all relevant environmental information to comply with the Clean Water Act and reporting requirements of the New Jersey Department of Environmental Protection (NJDEP). The DIAMS capabilities include identifying drainage infrastructure, maintaining inspection history, mapping locations, predicting service life based on the current condition states, and assessing present asset value. The DIAMS also contains several different repair, rehabilitation and replacement options to remedy the drainage infrastructure. 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 module will output data into categories including inspection, cleaning, repair, and condition states. The process will direct users and decision makers to evaluate work orders, which will be reported in summaries, allowing the best choice for asset performance implementation for each asset type. Thus, making DIAMS an indispensable asset management and environmental information management tool. Possible improvements to DIAMS includes the system wide design improvements to accommodate impacts of climate change.
