What This Exam Validates

The PE: Geotechnical Engineering exam is a computer-based professional certification administered by NCEES. It evaluates technical proficiency in geotechnical practice, including site characterization, soil mechanics, earthquake engineering, and foundation design. The exam consists of 80 questions and lasts 540 minutes. It requires the application of design, analysis, and methodology across ten distinct domains to ensure professional competency in geotechnical engineering projects for licensed civil engineers.

Who Should Take This Exam

This exam is intended for civil engineers with professional experience in geotechnical design and construction. Candidates should be familiar with soil mechanics, laboratory testing, and the application of ASD or LRFD methods in professional practice.

Skills You Should Be Ready to Demonstrate

How to Prepare

Review the NCEES PE Civil Reference Handbook and the specified design standards. Practice solving problems using both SI and U.S. Customary units. Focus on the application of design standards and various FHWA Geotechnical Engineering Circulars. Use the provided electronic references to practice navigating searchable PDF chapters efficiently, as these will be your primary resources during the 540-minute test session.

Domain Study Guidance

Site Characterization: Study Guidance

This domain evaluates candidate proficiency in site characterization, subsurface exploration planning, and field sampling techniques. It covers the identification, interpretation, and engineering classification of soil and rock materials derived from various site investigations.

Soil Mechanics, Laboratory Testing, and Analysis: Study Guidance

This domain focuses on the physical and mechanical properties of soils, phase relationships, index properties, and laboratory testing procedures. Candidates analyze stress distribution, consolidation, shear strength, and permeability characteristics within soil masses for engineering applications.

Construction Observation, Monitoring, and Quality Assurance/Quality Control and Safety: Study Guidance

This domain covers field observation, quality assurance, and quality control during geotechnical construction operations. It emphasizes monitoring earthwork compaction, evaluating instrumentation data, assessing trench safety, and ensuring compliance with project site specifications and requirements.

Earthquake Engineering and Dynamic Loads: Study Guidance

This domain addresses seismic site characterization, dynamic soil properties, and earthquake engineering principles. Candidates evaluate soil liquefaction potential, seismic hazard analysis, ground response, and structural dynamic loading on various geotechnical systems during seismic events.

Earth Structures, Ground Improvement, and Pavement: Study Guidance

This domain involves the engineering design and evaluation of earth structures, slopes, and pavement systems. Candidates perform slope stability analyses, select suitable ground improvement methods, and design flexible or rigid pavement foundations for infrastructure projects.

Groundwater and Seepage: Study Guidance

This domain covers subsurface fluid flow, groundwater hydraulics, and seepage analysis within porous geotechnical materials. Candidates evaluate permeability, construct flow nets, design dewatering systems, and implement effective seepage control measures for various geotechnical projects.

Problematic Soil and Rock Conditions: Study Guidance

This domain focuses on identifying challenging subsurface conditions and engineering suitable mitigation strategies. Candidates analyze expansive or collapsible soils, frost susceptibility, sensitive clays, organic deposits, and unstable rock slopes during the project planning phase.

Retaining Structures (ASD or LRFD): Study Guidance

This domain addresses the design and stability analysis of retaining structures using ASD or LRFD design methodologies. Candidates evaluate lateral earth pressures, external and internal stability, wall mechanics, and ground anchor systems for structural support.

Shallow Foundations (ASD or LRFD): Study Guidance

This domain covers the engineering design and structural analysis of shallow foundation systems using ASD or LRFD standards. Candidates evaluate ultimate bearing capacity, immediate settlement, consolidation settlement, and allowable foundation bearing pressures for various structures.

Deep Foundations (ASD or LRFD): Study Guidance

This domain focuses on deep foundation systems, including driven piles and drilled shafts analyzed under ASD or LRFD methodologies. Candidates evaluate axial load capacity, lateral displacement, pile group performance, settlement, and dynamic load testing procedures.

Exam-Day Guidance

The exam is computer-based and closed book. You will have access to the NCEES PE Civil Reference Handbook and specific design standards as searchable PDFs. Manage your time across the 80 questions to ensure completion within the 540-minute duration.
