Geotechnical Engineering

Whether it is evaluating the foundation requirements of a building addition or determining the slope stability and retaining wall requirements for a particular site, a thorough understanding of a project’s subsurface conditions is critical to the design of practically every project. LDG provides site characterization expertise with geologic and seismic hazards analyses to support design, identifying critical conditions early in the project so potential geohazards can be address and/or mitigated. We offer a complete range of geotechnical services including site exploration and development, geotechnical engineering (slope design and landslide remediation), wall design, trenchless construction design, subsidence risk analysis, and more. With extensive experience in field investigations, lab testing, analysis/design, and construction support services, LDG’s geotechnical staff begins work on each project during the concept stage. Our involvement continues through the design phase into project construction. This unique approach to geotechnical engineering ensures our staff is intimately familiar with a project, which helps us deliver right-sized and cost-effective solutions.

Site Investigations

We provide site characterization expertise with geologic and seismic hazards analyses to support our clients’ design. Our experts identify critical conditions early in the project so potential geohazards can be addressed and/or mitigated. In addition to standard testing, we do in-place field testing such as California Bearing Ratios (CBR) and Dynamic Core Penetrometer (DCP) testing.

Foundation Design

We determine the right foundation solution for all types of structures including walls, bridges, buildings, wind turbines, and tanks. Based on the site conditions, we determine the correct foundation for each unique project, such as shallow (spread footings, mats), intermediate (ground improvement methods), or deep foundations (piles, drilled shafts, auger cast).

Retaining Walls

We use geotechnical intelligence to determine the correct wall type for a project’s specific conditions. Our experts help determine the best choice whether it’s cast-in-place concrete, soldier pile and lagging, mechanically stabilized earth (MSE), gabion, or a soil-nail wall.

Trenchless Construction Design

We have trenchless technology professionals with experience in pipeline installations such as horizontal directional drilling, jack and bore, and pipe ramming for liquid and gas, water, and sewage pipelines.
