PhD Civil Eng: Construction Management Focus Admissions Questions

<p>Hello. I have a few questions regarding admissions to PhD programs in Civil Engineering with a focus on construction management / engineering management (whatever you wanna call it, it seems to go by a different name at every school). I have kind of a unique situation.</p>

<p>I attended a UC for undergraduate and received a BA in Economics. While attending there I was not the best student and earned around a 2.85. After my undergraduate I entered into a MS Civil Engineering program focused on CM and became more focused in my studies and have earned over a 3.9 with three courses remaining; however, I do not go to a top tier as I attend a CA State University. If you are curious how the program works, you basically start over doing the undergraduate program minus the GE's then take the Master's level courses.</p>

<p>1) Considering that I have a BA in something other than Civil Engineering, how large, if it is, of a burden is this?
2) With good GRE scores and letters of recommendations what sort (tier) of school would be a realistic possibility?
3) A general question about CM programs (if anyone here has been involved in one) how rigorous are the math requirements in PhD programs?</p>

<p>Thank you in advance :)</p>
