What Is Geotechnical Engineering?
Geotechnical engineering is a branch of civil engineering concerned with the behaviour of soil, rock and groundwater and how these conditions affect buildings, roads, foundations, retaining structures and other infrastructure.
Before a project is designed or constructed, a geotechnical engineer may need to assess:
- Soil composition and engineering properties
- Subsurface conditions and groundwater
- Foundation support requirements
- Settlement potential
- Slope stability and ground movement
- Excavation and earthwork conditions
- Pavement subgrade performance
The scope of investigation depends on the site, the proposed development and applicable project requirements. Geotechnical findings help the project team make informed decisions about foundation systems, site preparation, earthworks and other design considerations.
Our Geotechnical Engineering Services in British Columbia
1. Geotechnical Site Investigations
A geotechnical site investigation helps establish the subsurface conditions relevant to a proposed construction project.
Depending on the site and project scope, an investigation may include a site review, borehole drilling, soil sampling, laboratory testing, groundwater assessment and engineering analysis.
The findings help identify ground-related constraints and provide information for foundation design, excavation planning and other construction decisions.

2. Geotechnical Reports
A geotechnical report documents the site conditions investigated and provides engineering recommendations for a proposed project.
Depending on the scope, a report may address:
- Subsurface soil and groundwater conditions
- Foundation design parameters
- Settlement considerations
- Site preparation and earthworks
- Excavation and shoring considerations
- Slope stability and drainage
- Construction recommendations
Whether a report is required for a building permit or development application depends on the municipality, project type, site conditions and applicable requirements. Confirm the requirements with the relevant authority and project professionals before proceeding.

3. Foundation Design
Foundation design considers the loads from a structure alongside the engineering properties of the supporting ground.
Pacific Geotechnical provides foundation engineering support based on project requirements and site-specific conditions. Recommendations may address shallow foundations, spread footings, mats or other foundation systems where appropriate.
Geotechnical analysis helps the design team evaluate bearing resistance, settlement and other ground-related factors that can influence foundation performance.
The suitable foundation system depends on the investigation findings, structural requirements and overall design.
4. Slope Stability Analysis
Projects near slopes, steep terrain or areas with potential ground movement may require a geotechnical slope stability assessment.
A slope stability study may evaluate site geometry, soil properties, groundwater conditions and relevant loading conditions to assess stability and inform engineering recommendations.
Depending on the project, recommendations may address drainage, grading, retaining structures or slope stabilization measures.
The assessment scope should reflect the site’s conditions and the potential consequences of slope movement.
5. Pavement Assessment and Design
Roads, parking areas, driveways and other paved surfaces must be designed for their intended use, expected traffic and supporting ground conditions.
Our pavement-related services may include pavement assessment, subgrade evaluation and pavement design recommendations for relevant development projects.
Geotechnical input can help the project team evaluate subgrade conditions and select an appropriate pavement structure based on available site information and design requirements.
6. Earthwork and Excavation Design
Earthwork and excavation activities can affect site stability, neighbouring properties and construction sequencing.
Geotechnical engineering input may be needed to evaluate soil conditions, excavation constraints, temporary or permanent slopes, and ground support requirements.
The recommendations depend on excavation depth, soil and groundwater conditions, nearby structures and the proposed construction method.
7. Geotechnical Support for Residential Developments and Subdivisions
Residential construction and land development can involve several interconnected geotechnical considerations, from initial site investigation to foundation recommendations and construction-stage reviews.
Pacific Geotechnical works with project teams on residential development and subdivision projects. The scope of geotechnical support depends on the number and type of proposed structures, site conditions and development requirements.
For projects involving multiple buildings or phased construction, early coordination between the geotechnical, civil and structural teams can help identify ground-related issues before they affect later design stages.
8. Commercial and Industrial Projects
Commercial and industrial developments may involve larger building loads, extensive paved areas, retaining structures, excavations or other site-specific engineering challenges.
Geotechnical services can support the project team by assessing subsurface conditions and providing recommendations relevant to the proposed development.
The investigation and reporting scope should be established around the planned building, anticipated loads, site constraints and applicable project requirements.
9. Geotechnical Due Diligence
Before purchasing or developing a property, it can be useful to understand potential geotechnical constraints.
A due-diligence geotechnical review may help identify issues requiring further investigation, such as challenging soil conditions, slope-related concerns, groundwater considerations or potential foundation constraints.
The scope may range from a review of available information to a more detailed investigation, depending on the property and the decision being made.
Geotechnical due diligence does not replace other necessary property, environmental, structural or legal assessments.
10. Field Reviews During Construction
Geotechnical field reviews can help assess whether relevant site conditions observed during construction are consistent with the assumptions and recommendations in the geotechnical documents.
Depending on the agreed scope, reviews may address exposed subgrade, foundation bearing surfaces, fill placement or other geotechnical aspects of construction.
The required review frequency and reporting should be established with the project team and relevant authority. Field reviews are not a substitute for the contractor’s construction responsibilities or other required inspections.
Why Geotechnical Engineering Matters in British Columbia
British Columbia includes a wide range of terrain, geological conditions and development settings. Conditions can vary between sites, even within the same community.
A project may need geotechnical assessment to address factors such as:
- Variable soil strength and composition
- Groundwater and drainage conditions
- Potential settlement
- Sloping terrain and ground stability
- Excavation and earthwork constraints
- Foundation support requirements
- Pavement and subgrade performance
A site-specific investigation helps the design team make decisions based on the ground conditions relevant to the actual project, rather than relying on assumptions alone.
When Should You Hire a Geotechnical Engineer?
Consider involving a geotechnical engineer during the early planning stages if you are:
- Building a new home or commercial building
- Planning a townhouse development or subdivision
- Preparing a development application or building permit
- Developing land with a slope or unusual ground conditions
- Planning significant excavation or retaining structures
- Designing roads, parking areas or other paved surfaces
- Assessing a property before purchase or redevelopment
- Responding to settlement, drainage or ground movement concerns
Early consultation can help clarify what investigation, reporting and engineering input may be appropriate before major design or construction decisions are made.
