A.P. Underkofler Associates provides consulting and systems engineering services for a wide range of clients. Our history has been built on customer application and database development for the utility, pharmaceutical, and transportation industries and has grown to encompass small businesses with unique requirements, especially businesses with railroad themes. Sometimes these solutions require a hands-on approach, as in a toll plaza installation in which we assisted, field photography, or even the construction of model display benchwork.

Our “data repair” support service aids you in collecting, correcting, and merging data from various sources and flowing it into a homogeneous, unified SQL database. This includes on-the-fly spelling corrections, item verification where possible, normalization, and numeric precision adjustments as much as possible with the original data. This is an invaluable service to merging companies combining historically diverse data stores.
