• Drilling & Sampling

  On-site excavation, test borings, and expedited sampling matched to contractor schedules.

• Soil Testing & Laboratory Analysis

  Laboratory evaluation of soil properties including Atterberg Limits, moisture content, settlement, and post-injection swell testing.

• Foundation Design Recommendations

  Engineering criteria for foundation type, depth, and allowable bearing capacity across a range of vertical loads.

• Slope Stability & Earth Retention Analysis

  Stability analyses for earth slopes and excavation cuts, including below-grade soil stress analyses for active, at-rest, and passive pressures.

• Pavement Design

  Pavement design and materials characterization for roadway and site-development projects.

• Land Development Consulting

  Project-specific consulting integrating geotechnical and environmental findings with local, city, and state codes to support efficient land development.

Collaborative quality assurance partnering with owners, design teams, contractors, and inspectors to verify compliance with construction plans and specifications throughout all project phases.

• Soil Compaction Testing

  Field and laboratory compaction testing and inspection to verify earthwork meets specified density requirements.

• Concrete & Asphalt Testing

  Sampling, testing, and reporting on concrete and asphalt materials per ASTM and TxDOT standards.

• Structural Steel & Masonry Inspection

  Reinforcing steel inspection, structural masonry testing, and post-tension cable inspection during construction.

Due diligence environmental services supporting land development and property transactions, including Phase I and Phase II ESAs, water sampling, and environmental impact studies.

• Phase I ESA

  Regulatory records review and site reconnaissance to identify recognized environmental conditions on a property.

• Phase II ESA

  Subsurface investigation and sampling to characterize contamination identified during a Phase I assessment.

• Water Sampling

  Groundwater and surface water sampling to support environmental due diligence and regulatory compliance.

• Environmental Impact Studies

  Studies evaluating potential environmental effects of proposed land development activities.
