Services
Forensic Engineering
Our forensic engineering services investigate structural, mechanical, and electrical failures to determine root causes. We employ advanced diagnostic techniques and laboratory testing to provide clear, defensible conclusions. Our engineers deliver expert testimony and visual evidence that simplifies complex technical issues for legal proceedings.
Gas Explosion Investigations
Specialized investigations into natural gas and propane explosions combine field analysis with laboratory testing. Our certified experts examine pipeline integrity, appliance operation, and code compliance to identify failure points. We provide comprehensive reports and courtroom-ready visualizations that clarify complex incident sequences.
Carbon Monoxide Analysis
We conduct detailed assessments of carbon monoxide sources through field testing and laboratory analysis. Our engineers evaluate ventilation systems, appliance operation, and soil gas migration patterns. Findings are presented with 3D modeling to demonstrate exposure pathways and safety risks.
Structural Failure Analysis
Our team examines construction defects and structural failures using advanced diagnostic tools. We assess material performance, design adequacy, and code compliance to determine failure mechanisms. Reports include remediation recommendations and visual evidence for legal proceedings.
3D Computer Graphics
We create detailed 3D models and animations that visually communicate technical findings. These graphics transform complex engineering data into clear demonstrative evidence for courtroom presentations. Our specialists integrate field data with simulation results to show failure sequences accurately.
