Innovative Geotechnical Solutions

What is under a piece of property is as important as what's on it. This is especially true when construction is being considered. Properly performed geotechnical engineering can result in improved and more economical foundation design and less construction delays.

At Pattison Engineering, we believe that there is more than one way to approach a building project. We provide designers, builders, and owners with solid, reliable, proven engineering advice, without advising typically overbuilt foundations which cost owners more to build while providing no engineering value.

Our Geotechnical Services Include:

  • Geotechnical Site Evaluations
  • Soil Mechanics Laboratory Services
  • Mechanically Stabilized Wall Design
  • Inspection and Testing
  • Foundations and Specialty Analysis and Recommendations
  • Soil Stabilization and Ground Improvement
  • Slope Stability Analysis
  • Settlement Analysis
  • Forensic Investigations

Our Process

Our common sense approach to soils engineering will benefit your project from both a cost and schedule standpoint, while maintaining a high degree of quality and without increasing your risk. We can show you how to spend less money on your building foundations, spend less time getting your building "out of the ground," and maintain proven engineering practices at the same time!

On-Site Testing and Monitoring

Pattison Engineering Performs On-Site Soil Testing

Our engineers will visit your intended construction site and conduct analysis of the subsurface conditions. We monitor grading, site utility, and subgrade construction by conducting appropriate tests to confirm material acceptability and compaction.

By performing on-site tests and monitoring, we:

  • Provide an overview of earth grading activities
  • Suggest alternatives in construction equipment and procedures
  • Determine the need for moisture adjustment
  • Analyze the suitability of soils for structural fill
  • Evaluate the need for drainage, undercutting, stabilization, or geosynthetics

Laboratory Analysis

Pattison Engineering's In-House Laboratory

We will conduct a thorough laboratory analysis of your construction site's soil conditions at our In-House Laboratory. Analysis are conducted in conformance with applicable standards and specifications, and are verified through a proven quality assurance program.

Our laboratory is also capable of providing Comprehensive Construction Materials Testing. For more information, Click Here.

Engineering Analysis

Pattison Conducts Engineering Analysis

After laboratory analysis is complete, our engineers will evaluate the subsurface conditions of your intended site development and suggest ground improvements as necessary.

Our engineers have extensive knowledge in evaluating foundation structures including:

  • Pavement design and evaluation
  • Post-tension and mat foundations
  • Shallow spread footing foundations
  • Drilled piers, driven, and auger-cast piles
  • Excavation/shoring evaluation
