To transfer to upper level in civil is around a 2.85 now. It's not very high because there's room for a lot of students (~1200). It's a great department, in the top 10 in the country. Personally, I think it's getting better because they are making several changes, including bring the 200-level classes under the control of the department instead of the college of engineering to make them more relevant to civil engineers. Also, due to big donations from the Zachry family, there will be more of an emphasis on construction engineering and management. CE&M is one of 9 specialties. Others are general, structural, transportation, geotechnical (soils), water resources, environmental, materials, and coastal and ocean engineering (it's own degree program).
Every class I've taken has been taught by the actual professor, and they all care about their students and want us to succeed. The department is very, very good at supporting their students during job and internship searches, student competitions, and research opportunities. Relevant internships and co-ops are STRONGLY encouraged. Full-time job placement has been 100% for the past couple of years. Civils are always in demand somewhere.
They have tons of scholarship opportunities and close ties with several engineering firms.
