Why civil? Structural, or electrical or mechanical would make sense, but civil has very little overlap with architecture.

if you want to specialize in infrastrcuture projects civil can be beneficial on the architectural side.

I knew someone who sub-specialized in resource management and geotechnical engineering, we had some pretty awesome conversations. 

They mostly dealt with site issues though. did very little architecturing.

how does one make a transition from a B.Ach to MS in civil engineering?  Marie, did you take pre-requisite courses?  and where are trying to obtain your MS in Civil Engineering?

just asking because i want to consider that as an option for myself. 

And I do have to agree that structural would be more complimentary if that is what you are trying to do.  dont know why electrical/mechanical though. Those seem like it's a whole different ball park. with an M.S degree in electrical/mechanical, you might as well quit the field of architecture and do that strictly since job and pay is a lot more desirable. 

I want to do civil to deal with city infrastructure particularly hydrology.  Think water resource engineering, stormwater systems, wastewater systems.  I do have to take several pre-req's calc 3, linear algebra, differential equations, fluid mechanics, calc 3 based statics.

Some universities allow you to take pre-req's concurrently.  All said and done, it will take me 2.5 years to finish and sit for the EIT.  Electrical and Mechanical require much more work - electrodes and diodes, circuits, electrostatics.

Double stamping CD's? It could be in the future....

your comment makes me want to go back to school for civil engineering.

What architects think of as "structural engineers" typically have their education and degrees in civil engineering anyways, BTW. Structural engineering is often considered a specialty subset of civil engineering.
