Overview of FE Civil Engineering
The Civil Engineering discipline on the FE exam tests your ability to apply fundamental principles of civil engineering to real-world problems. Civil is the most popular FE discipline, and this section draws heavily from structural analysis, geotechnical engineering, hydraulics and water resources, transportation, and construction. Mastering these topics requires a strong foundation in statics, mechanics of materials, and fluid mechanics.
Key Topics
Structural Analysis
Structural analysis questions test your ability to determine internal forces (shear, moment, axial) in beams, trusses, and frames. You should be comfortable with free-body diagrams, equilibrium equations, method of joints, method of sections, and influence lines. Understand deflection calculations using the double integration method, moment-area theorems, and conjugate beam method. Know how to classify structures as stable, unstable, statically determinate, or statically indeterminate.
Geotechnical Engineering
Geotechnical topics include soil classification (USCS and AASHTO systems), phase relationships (void ratio, porosity, degree of saturation, unit weight), Atterberg limits, compaction (standard and modified Proctor), and permeability (Darcy's law). Understand effective stress, pore water pressure, consolidation theory (Terzaghi one-dimensional consolidation), settlement calculations, bearing capacity (Terzaghi and Meyerhof equations), and lateral earth pressure (Rankine and Coulomb theories). Retaining wall stability checks for overturning, sliding, and bearing are commonly tested.
Hydraulics and Water Resources
This area covers open channel flow (Manning's equation, specific energy, hydraulic jump, critical flow), pipe flow (Bernoulli's equation, Darcy-Weisbach, Hazen-Williams), pump systems, and hydrology. Know how to size pipes, calculate head loss, design open channels, and apply the rational method and SCS curve number method for stormwater runoff estimation. Understand unit hydrographs and reservoir routing.
Transportation Engineering
Transportation topics include geometric design of highways (horizontal and vertical curves, sight distance, superelevation), traffic flow theory (density, flow, speed relationships), level of service analysis, signal timing, and pavement design. Be familiar with AASHTO design standards, stopping sight distance calculations, and the fundamental diagram of traffic flow.
Construction Management
Construction topics focus on project scheduling (CPM, PERT, activity-on-node networks), cost estimation, earthwork calculations (average end area method, mass diagrams), and construction safety. Understand how to determine the critical path, float, and project duration from a network diagram.
Study Strategy
The FE Civil exam is broad, so prioritize the topics with the highest weight. Practice using the FE Reference Handbook during your study sessions since it is the only resource available during the exam. Focus on setting up problems correctly and identifying which equations from the handbook apply to each scenario. Use flashcards for formulas and mini exams for timed problem-solving practice.
