Capabilities

Geotechnical Engineering

Service website

Conducting detailed subsurface exploration and assessment to characterize soil and rock conditions at project sites. By analyzing subsurface factors, the practice identifies potential hazards and provides critical parameters for safe construction.

  • Subsurface Exploration and Soil Testing

    Characterizing site conditions through systematic field exploration, soil sampling, and laboratory analysis to identify critical subsurface parameters.

  • Slope Stability Analysis

    Evaluating soil and rock slopes to identify potential sliding hazards and designing stabilization measures to protect structures and infrastructure.

  • Liquefaction Hazard Assessment

    Analyzing saturated cohesionless soils under seismic conditions to determine liquefaction potential and recommend mitigation strategies.

  • Settlement and Bearing Capacity Analysis

    Predicting foundation settlement and determining soil bearing capacity to prevent structural damage and ensure long-term stability.

Foundation Design

Service website

Developing safe and cost-effective foundation recommendations based on site-specific geotechnical evaluations. Solutions are tailored to support structural loads across varying soil profiles.

  • Shallow Foundation Design

    Designing spread footings, strip footings, and mat foundations for structures where near-surface soils provide adequate bearing capacity.

  • Deep Foundation Systems

    Engineering pile foundations, drilled shafts, and other deep support systems to transfer heavy structural loads to competent deep soil or rock strata.

  • Pile Load Testing

    Performing field load tests on deep foundation elements to verify design capacities, optimize pile lengths, and confirm performance.

GeoDesign and Earth Retention

Service website

Blending geotechnical engineering insights with innovative structural design to solve complex site challenges, stabilize slopes, and optimize usable land area.

  • Segmental Block Retaining Walls

    Designing modular gravity wall systems, including specialized systems like Verti-Block, Redi-Rock, Allan Block, and Lock + Load.

  • Mechanically Stabilized Earth Walls

    Engineering reinforced soil structures that utilize geosynthetics or metallic reinforcement to support steep slopes and vertical grade changes.

  • Temporary Shoring and Excavation Support

    Designing structural systems to support open excavations, protect adjacent utilities, and ensure safe working conditions during construction.

  • Sheet Pile and Soldier Pile Walls

    Engineering driven sheet piles and drilled soldier pile-and-lagging systems to provide reliable lateral earth support in challenging environments.

Infrastructure and Pavement Engineering

Service website

Designing durable pavement structures and managing drainage to support transportation and site development projects.

  • Flexible and Rigid Pavement Design

    Developing structural designs for asphalt and concrete pavements tailored to traffic loads, subgrade conditions, and environmental factors.

  • Low Impact Development Stormwater Management

    Providing geotechnical evaluations and infiltration testing to support sustainable stormwater management and low impact development designs.
