I'm building a QA data validation tool and the first step in the process if the data aligns within the extent of the state of Alabama and more importantly in the rightful location. How do I determine this considering that the DGN files may have different coordinate references, ie. local coordinate, grid, state plane, etc.

Hi @salvaleonrp
when you read your source dgn-files, please select the correct source Coordinate System(s) on the Reader(s) (see Add Reader dialog or in Navigator). You can also use CordinateSystemSetter transformer to 'label' the data with the correct coordinate system. Unfortunately, at the moment FME does not support reading/writing coordinate system information from/into DGN.
After the data is read and made coordinate system aware (either with the Reader parameter or with CoordinateSystemSetter) you can use CsmapReprojector to bring all source datasets to the same coordinate system for alignment QA.
