What you may find is that you can get started in this field without the second degree. Like perhaps you could get a civil engineering job at a geotech firm, and pick up a lot by working there, attending professional conferences, taking a course here and there. Then maybe after a couple of years you could go back to school part time and get the official degree if you felt you needed it for your specialization. I think there's a lot to be said for getting out there and working for a few years before committing to another graduate program. How is the engineering job market?
