Forensic Engineering and Forensic Soil Analysis

Forensic engineering Professionals working with law firms, insurance companies, and litigations to meet your objectives. The most experienced Forensic Engineering Company in Southern California

Geoforensics is after-the-fact evaluation of issues and occurrences that involve the ground such as landslides, earthquakes, and natural hazards and disasters. Our experts know what they are talking about as they work around design and construction on a regular, hands-on basis. We have an exceptionally broad base of both experience and knowledge, and are experts in many fields including soil, water, moisture, vapor, chemical fate, concrete, corrosion, soil moisture and groundwater, and drainage. This understanding is enhanced and tempered by strong practical experiences with nearly all aspects of grading, development, foundations, and their behavior. We are not merely “professional experts”. Rather, the majority of our daily work is practical hands-on design and development. We thrive in spaces that most experts find uncomfortable.

We are experienced in various legal proceedings including mediation, arbitration, depositions, trials, expert forums, and public presentations. President of G3SoilWorks, Larry Fanning, has served as a Judicial Reference in complex CD cases, a Subject Matter Expert to the Board of Registration for Engineers and Geologists, and was appointed and served as a board member to the California State Mining and Geology Board. Other members of our senior staff have similar levels of experience and expertise with regard to forensics and expert witness services.


Thanks to our expertise and methods on determining the properties on soils and structures, we are capable of running accurate investigations on broken down constructions that will gauge the elements that cause such breakdown in the first place.

Alongside this, we are able to draft up plans when necessary to repair such distress on buildings with efficiency, accuracy, and effectiveness. Whatever the problem might be with the integrity conditions in a structure, we provide the tools to determine what has caused the problems that have arisen and what can be done to remedy them.

We have ample trajectory in presenting our expertise as an impartial third-party. More than just consulting or presenting an opinion, we provide our learned perspective in an unembellished and easy-to-digest manner as it is often required when dealing with litigations that require a forensic engineering analysis.

We use our foundation geotechnical studies and seek their application from a forensic engineering perspective. Providing a clear picture of foundation cases where there may be uncommon or potentially detrimental conditions, drawing up their past and future behavior for both risk assessments and geoforensic studies.


Assessment of property damage is performed when there is a need to determine how a structure has been altered through any form of interaction with outside forces. This includes cause-and-origin studies and added a factors of analysis on whether the disturbance has occurred naturally, accidentally or deliberately.

We study and provide professional consultancy on cases of foundation repair and soil stabilization to determine the proper actions to take on a project that needs it. Having experience in these processes, we are able to draw up a history of their performance, with an accurate analysis of their end results from a third-party perspective.

A slope failure occurs when natural events break down a sloped soil making it gradually unable to support its own integrity, causing a sudden collapse. Given the tragic loss that can be often derived from this phenomenon, we take the analysis of slope failure events very seriously and find the right solutions to identify the exact causes and consequences that brought it to pass.

Top of slope creep effects occur when stress, gravity, and other natural factors contribute to the downward slope push of soil over a long period of time. This can be measured by forensic engineering experts with the right tools and expertise, and we provide consultancy on both field analysis and desk studies that must be performed to determine the factors and causes of such phenomenons.

Expert Witness

Our role as designated expert witnesses is possible through more than just expertise in forensic engineering, we have a knowledge and experience in aspects of geotechnical engineering hydrogeology, seismology, and other technical fields. It is also our experience in the practice of such sciences that has allowed us to determine the characteristics of all aspects of soils and their behaviors.

Our role as geoscience experts has, in turn, been our base to provide scientific litigation support services as we have done for some time now, assisting as geoscience experts in all aspects of litigation where forensic engineering expertise is needed.
