Civil and Infrastructure Engineering, PhD


Banner Code: VS-PHD-CEIE

School: Volgenau School of Engineering 

Department: Civil, Environmental and Infrastructure Engineering   

The Doctor of Philosophy in Civil and Infrastructure Engineering (CIE) was created to prepare students for advanced leadership positions in research and development in the public or private sector, academics, or government. Students may elect to study in the areas of: environmental engineering, geotechnical engineering, water resources engineering, construction engineering and management, infrastructure systems engineering, structural engineering, or transportation engineering. Admitted students will complete both required and applicable course work in their technical interest area based on a plan of study prepared with a doctoral advisor.  They will take qualifying exams that assess student’s breadth of knowledge at the graduate level and competency to conduct research.  They will gain experience through required teaching at the undergraduate level. They will form a doctoral committee, prepare, then defend a dissertation proposal leading to PhD candidacy.  Finally, they will conduct original scholarly research and prepare, then defend a doctoral dissertation.  Both part-time and full-time study is available.

Admission Requirements 

All general George Mason University and specific Volgenau School admission requirements (including deadlines) apply. In addition, all applicants, including Mason undergraduates, must submit the following:

  • Official transcript of undergraduate and graduate course work,
  • For applicants whose official language is not English, official TOEFL scores which meet the minimum requirements set by the Volgenau School,
  • Three letters of recommendation from individuals knowledgeable about the applicant’s professional or academic work (at least two of the letters should be from individuals with doctorates),
  • Recent professional résumé,
  • Substantial statement of interest that includes a description of the specific area of proposed dissertation research, contacts the student has made with potential faculty advisors, and an explanation of career and research goals,
  • Official results of the GRE general test.

Admission decisions will be based on the student’s qualifications and the availability of a faculty advisor in their proposed area of research. The application materials will be reviewed by the department doctoral committee and decisions made with input from appropriate faculty members.

Financial support for outstanding applicants is available in the form of fellowships as well as research and teaching assistantships.  For best consideration, applicants are encouraged to apply early and to contact potential faculty advisors to express interest in support. 

Reduction of Credit 

Students must complete a minimum of 72 graduate credits, which may be reduced by a maximum of 24 credits from a completed master’s degree. Reduction of credit requires the approval of the program director or designee and the dean or designee of the school. They determine whether the credits are eligible for reduction of credit and applicable to the degree program and the number of credits to be reduced.

Degree Requirements


The PhD in Civil and Infrastructure Engineering requires 72 graduate credits, including 48 credits of graduate coursework and 24 credits of research. Admitted students are expected to hold a Bachelor of Science in Civil Engineering or degree in a closely-related science field.

Exceptionally-qualified students without a related Bachelor’s or Master’s degree may be admitted provisionally and required to take additional undergraduate- and graduate-level articulation courses prescribed by the doctoral committee, which will not count towards the PhD degree.

The following degree plan is based on a student who receives a full 24 credit reduction.  Students who do not receive a full credit reduction should choose additional credits in consultation with their advisor.

Doctoral Coursework (24 credits)


A minimum GPA of 3.50 is required and no C grades are allowed for the 24 credits earned beyond the MS.  A detailed plan of study will be prepared for each student upon acceptance into the program and in consultation with the faculty advisor, which outlines all course requirements to include:

Required Courses (6 credits)


 The following must be completed while in residence in the program.

Courses chosen with Advisor (18 credits)


Remaining courses, especially in the student’s technical interest area, will be chosen in consultation with his or her advisor in accordance with the following requirements:

  • A minimum of 9 credits at the 700-level or higher
  • A maximum of 6 credits of directed reading courses at any level (e.g., CEIE 796, CEIE 896)
  • A minimum of 3 credits of statistics at the 500-level or above outside the CEIE Department.
  • No cross-listed courses may apply to the degree.

Qualifying Exam


Based on demand, qualifying exams will be offered twice a year prior to the start of the fall and spring semesters. The qualifying exam is intended to test the student’s breadth of knowledge in their research area. Students entering with a MS degree are required to take the qualifying exams upon completing 18 credits in the program. Students entering without a MS degree must take the qualifying exam upon completion of 30 credits. Exceptional students may be allowed to take the exams earlier based on doctoral advisor recommendation and approval of the CEIE Graduate Coordinator.

The qualifying exam consists of two written exams and one oral exam. One written exam will be in the student’s primary research area. The other written exam will be in a student-selected secondary area. The level of knowledge for the primary exam is MS-level, while the level for the secondary exam is BS-level. The available examination areas include:

  • Area A: Water and Resources Engineering
  • Area B: Construction Engineering and Management
  • Area C: Geotechnical Engineering
  • Area D: Transportation Engineering
  • Area E: Infrastructure Systems Engineering
  • Area F: Structural Engineering
  • Area G: Environmental Engineering

At least 30 days before the scheduled exam date, students are required to request exams in their primary and secondary areas from the above list. A written exam for each area will be administered to the candidate, typically on the same day. The specific requirements for each exam (reading list, allowed references, etc.) will be announced prior to the exam date. On a second date, students are required to attend an oral interview with an examining committee of at least four members of the CEIE faculty. The interview will consist of discussion of the student’s written exam results as well as questions to determine preparedness to conduct independent research. Students will receive separate pass/fail grades for the primary and secondary written exams and an overall pass/fail grade for the qualifying exam.

Students who receive an overall pass grade are allowed to form a dissertation committee and to register for CEIE 998 Dissertation Proposal Preparation. Unsuccessful students who receive an overall fail grade are allowed to repeat the exam once. If the student receives a fail grade on one focus area exam, he or she must repeat that exam on the second attempt. If the student receives a fail grade on both focus area exams, he or she must repeat both exams on the second attempt. The second attempt at passing the qualifying exams must be within one calendar year or the next scheduled examination date, whichever is greater. Students who do not receive an overall pass grade on the second attempt are excused from the program.

Dissertation Research (24 credits)


Students become eligible for CEIE 998 upon passing the qualifying exam (preceding section).  Upon admission to candidacy, which requires satisfactory preparation and defense of a dissertation proposal, students may register for CEIE 999.

Dissertation Committee


A dissertation committee (separate from the examination committee) is formed upon successful completion of the qualifying exams.  The student, in consultation with their advisor, shall select two or more full-time CEIE Department faculty members, and at least one committee member from outside the department. At least three members of the committee are to be members of the Mason graduate faculty. All committee members must hold earned doctorates and possess applicable knowledge and experience in the student’s chosen topic.  The CEIE Faculty must approve the composition of the dissertation committee, specifically for outside committee members.  The committee must be formed and approved before admission to candidacy (described in the next section) and before registering for CEIE 999 Dissertation Preparation.  Substitutions to the dissertation committee are allowed with the approval of the CEIE Department chair.

Dissertation Proposal Preparation and Advancement to Candidacy


After successfully passing the qualifying exams and forming of a dissertation committee, the student may register for CEIE 998 research credits and begin preparation of the dissertation research proposal. At least 12 credits of CEIE 998 are required during which the student will consult with his or her advisor on the selection of an original scholarly topic and preparation of a formal research proposal. Students are also encouraged to register for the required CEIE 990 Civil and Infrastructure Dissertation Topic Presentation course during this time. Students must schedule a formal proposal defense (also known as the research competency exam) with all members of their chosen committee present. This may not be done before successful completion of the qualifying exams. Committee members should receive printed copies for the final proposal not less than two weeks prior to the scheduled defense date.

The research competency exam (proposal defense) includes the written proposal and a presentation of the planned dissertation research. The dissertation proposal defense shall not include already completed research. The dissertation proposal defense is the main opportunity for the committee to provide input and for the dissertation committee members to examine the student’s knowledge in higher-level course work and familiarity with existing and emerging research related to the student’s research area. After the student’s presentation, and after private deliberation, the committee makes a pass/fail determination that is given to the student by his or her advisor.

Students who pass the research competency exam are admitted to candidacy and become PhD Candidates. Students who do not pass the exam may, in consultation with their advisor, schedule a second exam within 120 days of receiving notice of the first exam result. Students who do not re-schedule and successfully pass the research competency within this period are dismissed from the program.

Dissertation Research and Defense


On successful completion of the dissertation proposal, students are to conduct original research under the guidance of their dissertation director and dissertation committee members. Students are not to schedule their dissertation defense sooner than two semesters after a successful proposal defense. During the dissertation research period, students must present their research at least once in the form of a department seminar. The dissertation must represent achievement in research, must be a significant contribution to the field of civil engineering, and should be deemed publishable in refereed journals. When the majority of the research has been completed, the candidate is to submit a written draft of the dissertation to the doctoral dissertation committee and schedule an oral pre-defense with the doctoral dissertation committee. The pre-defense is to be attended by the doctoral dissertation committee and the department chair.

A final, public, oral defense may be scheduled no sooner than one month after the conclusion of the pre-defense, which will allow for a minimum of two weeks to advertise it broadly. The final defense is to be attended by the doctoral dissertation committee and the department chair. On successful completion of the oral defense, students must submit a final publishable dissertation that meets the guidelines specified by the Guide for Preparing Graduate Theses, Dissertations, and Projects. If the student fails to defend the dissertation successfully, the student may request a second defense following the same procedures as the initial defense. This request has no time limit, other than the general time limits for the doctoral degree as per Mason policy. An additional pre-defense is not required; however, the student is strongly advised to consult with the committee before scheduling the second defense. If the student fails on the second attempt to defend the dissertation, the student will be dismissed from the PhD program. Following a successful public defense and completion of the final form of the dissertation, the dissertation committee recommends the candidate for the degree of Doctor of Philosophy.

Teaching Requirement


Because one of the characteristics of a good researcher and scholar is the ability to express ideas and concepts to a broader audience in a clear manner, each doctoral candidate will be required to organize and deliver a series of lectures or recitations in the CEIE Department to undergraduate students. Arrangements for the teaching requirement are made between the student and his or her advisor and will include a minimum of 21 hours of classroom contact time between the time the student passes the qualifying exams and defends the dissertation proposal.

Total: 72 credits
