Planning to work as a geotechnical engineer in Australia? Understanding the profession, required skills, and qualification assessment process is essential for engineers pursuing international career opportunities. Geotechnical engineers play a key role in soil analysis, foundation design, and ensuring the stability of infrastructure projects.

This guide explains the role of geotechnical engineers, the skills assessment process through Engineers Australia, and how engineers can prepare for career opportunities in Australia.

O'Terra Geotech Group, Inc. was founded in January 2003 as a full-service firm with expertise in geotechnical and materials engineering headquartered in Concord, CA.

Our professional team consists of licensed Geotechnical and Civil engineers and Engineering geologists, registered in the State of CA with decades of experience in geotechnical and materials engineering in the San Francisco Bay Area.

We are specialized in geotechnical consulting services for residential and commercial developments including:

Geotechnical (Soils) Engineering

Foundation Engineering

Soils and Foundation Investigation

-_Pavement Design

Geotechnical inspection

-_Landslide Investigation

Foundation Inspection

-_ Geotechnical Construction Inspection

We specialize in determining and finding a cost-effective way to design and build foundations for residential and multi-story commercial buildings and recommending solutions to resolve foundation distress problems. We specialize in landslide investigation and recommend cost-effective repair strategies. We also specialize in designing various types of retaining walls (on spread footing or drilled piers), geosynthetic reinforced embankment, below grade structures, and performing slope stability, seismic, and liquefaction analyses.

Foundation Engineering

Foundation engineering involves the determination of the best suited and most economical foundation types and depth for our clients' projects based on the strength of foundation soils and rocks. We provide geotechnical information, design data, and recommendations for slab-on–grade, mat foundation and drilled piers foundation to the project structure engineer. We conduct foundation inspections and evaluations of the existing structures and provide written recommendations to the project structural engineer for repair such as underpinning. If you'd like to learn more about all the foundation and geotechnical services we offer, contact us today at O'Terra Geotech Group, Inc.

Geotechnical Soils Engineering

For the last 15 years, O'Terra Geotech Group, Inc. has been committed to providing our clients with a wide range of geotechnical engineering services. Our professional engineering personnel are highly educated, have extensive experience and skills in the field of geotechnical and materials engineering to meet our clients’ need.

O'Terra Geotech Group, Inc. provides geotechnical engineering analysis, design, and recommendations for deep and shallow foundations, all types of retaining walls, geo-synthetic reinforced embankment (GRE), ground improvement, foundation settlements, and expansive soils, foundation underpinning, liquefiable soils, slope stability, and landslides, groundwater and drainage, and pavement design. We provide our clients with an investigation of building foundation failure and cost-effective remedial recommendations. We also provide our clients with geotechnical inspection and testing during construction and provide final construction inspection report required by cities and counties. To learn more about all our geotechnical services, contact us today at O'Terra Geotech Group, Inc.

Landslide Investigation

When buildings to be constructed on existing slopes we investigate the condition and stability of the slopes, perform stability analysis using computer program and provide written recommendations. For landslide project, we investigate the site, conduct foundation explorations and provide repair recommendations. The investigations may include borings, instrumentations, and monitoring. The repair solution may be drainage improvement, non-structural solution such as geo-synthetic reinforced earth (GRE) or structural repair involving various type of earth retaining structures.

Pavement Design

Pavement Design in both asphalt and concrete involve pavement thickness layer design (surfacing, base, sub-base and previous material). We provide recommendations for new pavement or existing pavement restoration.

Soils and Foundation Investigation

At O'Terra Geotech Group, Inc., we can provide you with all your soil engineering needs. Soils and foundation investigation involve soil borings, test pits, CPT sounding, using truck-mounted track-mounted and portable drilling rigs. Standard Penetration Test (SPT) is conducted at 5’ or less intervals. Expansive soils are soils that experience significant volume change associated with changes in water contents. These volume changes can either in the form of swell or in the form shrinkage and this is why they are sometimes known as swell/shrink soils. Key aspects that need identification when dealing with expansive soils include soil properties, suction/water conditions, water content variations temporal and spatial, e.g. generated by trees, and the geometry/stiffness of foundations and associated structures. Damage from to expansive soil often occurs as a direct result of interaction with vegetation and associated water content changes. Soils that experience moderate to severe swell/shrink problems are common in most counties of San Francisco Bay Area.

O'Terra Geotech Group, Inc. will provide geotechnical inspections and investigate the nature and extent of expansive soils and provide remediation recommendation. We will investigate expansive behavior both in the field and in the laboratory and the associated empirical and analytical tools to evaluate expansive behavior. Contact us today to solve all your soil and geotechnical services.
