Geotechnical Surveys, Studies & Analysis

Preliminary Surveys:

Preliminary geotechnical studies are smaller scale initial site reviews with limited exploration and analysis scopes that can provide a basic understanding of the geologic conditions of a proposed site before moving forward with site development plans. These studies typically include desk studies, subsurface investigations, and laboratory testing in order to provide the basics of site and soil characterization and a preliminary geotechnical report on expected conditions and foundation requirements.

The preliminary process often includes:

Early Site Selection
Limited Subsurface Evaluations
Preliminary Site Characterization
Soil & Foundation Preliminary Evaluation
Recommendations on Final Field Exploration Scope

Geotechnical Surveys:

Complete geotechnical studies are more comprehensive and related to a specific project. At this stage the project layout and general characteristics are know; as such, foundation recommendations of any type can be given depending on the type of soils encountered and the structural loads of the project; also general construction considerations are given.

The complete geotechnical process often includes the following items depending on type of project:

Early Site Selection
Subsurface Evaluations
Field Drilling and Sampling Services
Site Characterization
Construction Materials Investigation
Bearing Capacity
Soil & Foundation Evaluation
Shallow and Deep Foundations
Settlement Analysis
Retaining Walls

Slope Stability Analysis
Pavement Design
Feasibility Studies
General Construction Considerations
Geological Studies
Seismic Hazard and Liquefaction Analysis
Geohazard Assessment
Vibration Studies
Groundwater Flow Analysis

Linear Geotechnical Surveys:

Roadway, rail, pipeline, and utility infrastructure present a unique challenge for geotechnical engineering. Spanning across varying geologic conditions and terrains, these projects often require unique earthwork solutions, structural components and foundation designs and an understanding of the interaction between not only the geologic, but the environmental conditions the finished project will encounter.

Intertek-PSI has the ability to meet all of these challenges and more with geotechnical corridor studies that can include the following:
