GEOTECHNICAL SITE EVALUATIONS
We provide both initial and complete site evaluations to help our clients avoid unexpected problems. Our engineering geologists are specialists in evaluating soil, rock, and groundwater conditions for proposed and existing developments.
top
SLOPE STABILITY
Our geotechnical engineers and geologists are experienced in analyzing both the static and dynamic stability of existing and proposed slopes, and developing recommendations to stabilize slopes. Analyses are performed using appropriate stability methods and state-of-the-art computer software. Dynamic analytical methods range from pseudo-static analyses to slope deformation analyses.

HILLSIDE DEVELOPMENT/LANDSLIDE ANALYSIS
Our company is uniquely qualified in geotechnical studies and planning for hillside development. Our engineering geologists are very well trained in identifying landslides, assessing their impact on the development, and providing mitigating measures.
top
FOUNDATION ENGINEERING
Our geotechnical engineers have extensive experience in detailed geotechnical analysis and foundation design for sites with special considerations such as liquefaction, compressible and collapsible soils, expansive soils, fill/bedrock transitions, and deep fills. Our engineers have provided recommendations for all type of foundation options including: piles, mat foundations, post-tensioned foundations, standard slab-on-grade systems, etc. as well as various combination systems.
top
TRANSPORTATION PROJECTS
We have provided various levels of geotechnical services for many transportation projects including bridges, roadways, and railways. GMU engineers and geologists are intimately familiar with Caltrans standards, analytical methodologies and requirements.

GEOTECHNICAL INSTRUMENTATION
GMU has the capabilities and expertise to install and monitor geotechnical instrumentation including piezometers, extensometers, strain gauges, settlement gauges, and slope inclinometers. GMU has extensive experience in the interpretation of geotechnical monitoring data as well as other types of deformation monitoring (i.e. survey points).
top
FORENSIC ENGINEERING/DISPUTE RESOLUTION
We have provided forensic engineering services and third-party review services related to large landslides, mse wall/cribwall/retaining wall stability, settlement and subsidence, and many other projects. Select GMU personnel are experienced in deposition and court testimony.
top
PUBLIC WORKS CONSTRUCTION
GMU has provided investigative and design and construction services for reservoirs, dams, pipelines, bridges and many other types of public works projects.

APPLIED GEOPHYSICS
GMU provides seismic refraction services pertaining to rippability, fault, groundwater, and seismic response studies. GMU utilizes a state-of-the-art 12 channel seismograph to perform seismic refraction surveys.
top
EARTHQUAKE GROUND MOTION STUDIES
Our engineers and seismic geologists are capable of performing both probabilistic and deterministic ground motion analysis. Seismic response spectra can be developed for a wide variety of engineering structures.
top
LIQUEFACTION STUDIES
GMU engineers and geologists can perform detailed and comprehensive liquefaction and seismic settlement assessments. State of the art techniques implementing the latest technology (i.e. cone penetrometer testing, seismic refraction, insitu energy calibration for SPT testing, etc.) are utilized. Probabilistic as well as deterministic based analyses can be performed.
top
FAULT STUDIES
GMU geologists have performed a wide variety of fault studies in active and potentially active fault zones throughout California. Fault evaluations also include studies pursuant to the guidelines of the Alquist-Priolo earthquake fault zone act.
