Peterson Geotechnical Group

Specialists in Forensic Geotechnical Engineering

Since 2006, PGG has been a leader in the geotechnical consulting community in the Southwestern United States, providing expert analysis, consulting, and recommendations. We specialize in the analysis of foundation and soil movement, determining the root cause of complex issues and providing our clients with cost-effective advice. Our recommendations have been used to resolve construction disputes, to address soil movement and cracking inside existing homes and avoid problems during the early stages of new projects.

Our team of experts is able to diagnose the causes of soil movement that may lead to cracks in interior drywall, exterior stucco, concrete slabs, and flatwork. We also provide oversight of these recommendations during their implementation to ensure that repairs are performed correctly.

PGG also performs pre-construction geotechnical evaluations and special inspection services during construction. This allows us to put our experience investigating and diagnosing the cause of problems to use, resulting in a successful construction project.

Experienced

Over 75 years of combined education and experience studying soil conditions in the Southwestern United States, formulating recommendations, and overseeing their implementation.

Professional Team

The educational backgrounds of our project managers include bachelor’s and master’s degrees in civil engineering, geotechnical engineering, geology, and construction management.

Licensed

Licenses held by our staff include: Registered Professional Engineers in Arkansas, Arizona, Colorado, Florida, Nevada, New Mexico, Texas, and Utah, and licensed geologists in Arizona.

Our Services

Peterson Geotechnical Group specializes in Forensic Evaluations that involve evaluating the cause of post-construction soil movement. We also provide soil and foundation engineering solutions that include pre-construction and development feasibility evaluations, geotechnical evaluations (soil reports), density/compaction testing, and special inspections during construction. While our primary focus is on helping property owners, developers, contractors, and attorneys understand what may have gone wrong on a project, we use that experience to guide our recommendations on new construction projects.

Forensic Evaluations

PGG provides comprehensive forensic analysis for construction defect disputes, insurance claims, and property damage assessments. Our expert witness services support attorneys, developers, homeowners and for homebuilders in legal proceedings involving post-construction, soil movement issues, and construction-related damages. We evaluate single-family homes, commercial projects, municipal improvements, and pools to determine the cause of the issues. Our opinons and recommendations are used as part of the dispute resolution process and for performance of repairs.

Pre/New Contruction Geotechnical Evaluation

Our pre-construction geotechnical evaluations characterize site conditions and deliver engineering recommendations for foundation design, grading plans, and earthwork specifications for residential and light commercial projects. PGG provides ongoing construction oversight including compaction testing, building pad certifications, and quality assurance during site grading operations to ensure compliance with engineering specifications and building codes.

Special Inspections

PGG delivers municipal-required special inspection services across multiple construction disciplines including soils, deep foundations, driven piles, micropiles, helical foundations, masonry, and concrete construction. Our certified inspectors evaluate these areas of construction projects for conformance with the approved plans and specifications, providing detailed documentation and reporting to satisfy local jurisdiction requirements for building owners and contractors.
