Understand the Ground Before Altering It

We analyze geological conditions, soil materials and subsurface behavior to understand how they may influence project planning and development.

We combine field observations, subsurface investigation, testing, geophysical methods, mapping and spatial analysis to interpret the ground as a system and support better-informed technical decisions.

Geology and Materials Identification of geological units, materials, structures and variations across the site.
Subsurface Investigation Field observation, exploration, testing and direct and indirect methods according to project conditions.
Interpretation and Behavior Integrating evidence to understand how the ground may respond to development.
Understanding the Ground

The Ground Is More Than What We See at the Surface

Beneath a property, materials, structures and conditions may vary considerably. Understanding this variability is the first step toward interpreting how the ground may respond to development.

Soil and the subsurface result from geological, geomorphological and environmental processes operating over long periods. Consequently, two areas of the same property may have different conditions even if they look similar at the surface.

Bedrock depth, degree of weathering, natural deposits or fill, changes in material and interactions with water can alter ground behavior and affect different stages of a project.

Understanding the ground means recognizing its variability, relating surface observations to subsurface conditions and interpreting each finding in the context of the project.

Materials Soils, deposits, weathered rock, bedrock and fill can occur and vary within a single property.
Distribution Conditions may change both with depth and laterally across the site.
Water Moisture, drainage and groundwater may influence material properties and behavior.
Terrain Slope, landforms and geomorphological processes help explain the site's development and current conditions.
Subsurface Investigation

Understanding What Lies Beneath the Surface

The subsurface cannot be fully observed from the surface. Investigating it requires combining different sources of evidence to identify materials, their distribution and conditions that may influence ground behavior.

No single method can describe an entire site. Each observation, borehole, test or measurement represents part of a system that must be interpreted within its geological, geomorphological and spatial context.

We therefore select investigation techniques according to site characteristics, project type and the questions to be resolved.

Investigating the subsurface is not simply about collecting data: it is about combining evidence to develop a coherent interpretation of the ground.

Site Observation Terrain, outcrops, cut slopes, drainage, exposed materials and other evidence that help explain site conditions.
Direct Investigation Boreholes, soundings, test pits and other techniques allow direct observation and sampling of subsurface materials.
Testing and Measurements Ground properties can be assessed through field and laboratory tests selected to suit the investigation objectives.
Indirect Methods Geophysical methods investigate subsurface changes and structures through physical properties, complementing direct investigation.
An Integrated Investigation

Different Methods, One Coherent Interpretation

Evidence from observations, direct investigation, testing and indirect methods is analyzed together to identify relationships among materials, detect changes with depth and reduce uncertainty about ground conditions.

From Data to a Ground Model

Integrating Evidence to Understand the Ground

Each observation, borehole, test or measurement provides information about a specific location. By connecting these data, we can interpret material distribution and changes in conditions across the study area.

A borehole reveals ground conditions at one point; a test provides information on particular properties, while field observations document visible conditions. The challenge is to connect the evidence and understand what lies between the investigated points.

Geology, geomorphology, topography, subsurface exploration and findings from different investigation methods are integrated spatially to identify patterns, variations and relationships that are not always evident when each data point is considered in isolation.

A data point describes an observed condition. Combining it with other evidence allows us to build an interpretation of the ground.

Ground Units Identify materials with shared characteristics and establish relationships across the site.
Changes with Depth Interpret layer thicknesses, contacts, weathering horizons and vertical variations in the subsurface.
Spatial Variability Analyze how conditions may differ between areas of a property or project site.
Connections to the Surroundings Relate subsurface conditions to topography, drainage, water and other elements of the landscape.
Spatial Interpretation

From Isolated Points to an Integrated Subsurface View

Profiles, cross-sections, maps and Geographic Information Systems help organize and represent investigation findings. These tools make material distribution visible and support a conceptual model consistent with the available evidence.

Points Observations, boreholes, samples and measurements.
Profiles Relationships between materials and conditions at depth.
Maps Spatial distribution of conditions and units.
Model Integrated interpretation of the ground and subsurface.
Ground Conditions and the Project

Ground Conditions Inform Project Decisions

Building, excavating, grading or otherwise altering a site changes existing conditions. Understanding its characteristics beforehand helps identify issues to consider during project planning, design and construction.

The significance of a geological or geotechnical condition depends both on ground characteristics and on the proposed intervention.

A slope, a material change, the presence of fill, shallow bedrock or particular groundwater conditions may have different implications depending on a project's location, size and characteristics.

The objective is not to study the ground in isolation, but to understand how it interacts with the proposed development.

Loads and Foundations Material characteristics and distribution influence how the ground responds to structural loads.
Excavation and Earthworks Understanding materials and their variations helps anticipate conditions that may be encountered when modifying the ground.
Slopes and Hillsides Topography, materials, geological structure and water are among the conditions to consider on sloping sites.
Water and Drainage Water presence and movement may affect material conditions and influence excavations, slopes and other works.
Every Project Interacts Differently with the Ground

The Scale and Type of Development Also Matter

Investigation needs are not necessarily the same for a building, a residential development, an infrastructure project or work on sloping terrain. The scope must reflect site characteristics and the decisions that require technical support.

Buildings Subsurface conditions relevant to foundations, excavations and ground behavior.
Land Developments Ground variability across larger areas and different development zones.
Infrastructure Changes in materials and conditions along alignments or work areas.
Complex Sites Slopes, fill, heterogeneity or other conditions that may require more extensive investigation.

Different Tools for Investigating the Ground

Site characteristics and project requirements determine the most appropriate type of investigation. Studies, tests and exploration methods may be used separately or combined to obtain a more complete interpretation of soil and subsurface conditions.

The Method Depends on the Question

Not Every Project Requires the Same Investigation

The choice and combination of technical studies depend on ground characteristics, project type and scale, available information and the issues to be assessed. An initial consultation can help identify suitable investigation methods.

When Ground Information Is Part of a Regulatory Procedure

Depending on a project's location and characteristics, geological, geotechnical or soil information may be needed for studies and documents submitted as part of institutional procedures.

A technical study and a regulatory procedure are not the same. Studies investigate and document ground conditions, while a procedure is an administrative process before a public authority.

For some projects, the two are connected: a ground investigation may provide technical inputs to meet environmental, land-use or construction-related requirements.

Required studies should be defined according to project characteristics and the specific regulatory requirements applicable to each procedure.

The Ground Is Part of a Broader System

Geological and geotechnical conditions may be related to groundwater, natural hazards, environmental assessment and other spatial aspects of a project.

A Project May Require Several Disciplines

We Integrate Information When the Issue Calls for It

The relationship between geology, soils, water, terrain and environmental conditions depends on each site and proposed development. Where different disciplines overlap, evidence can be analyzed together to maintain a consistent understanding of the project.

Initial Consultation

Need to Understand Your Site Conditions Better?

Every project raises different questions. We can review the location, site characteristics, planned development and any technical or regulatory requirements you have already identified.

Based on that information, we can advise on the investigation, technical study or regulatory process that may be appropriate for your next steps.
