I develop technical and factual evidence foundation development in the case. Hands on, shirt-sleeve, field investigation and data acquisition. Testing and analysis. Trial preparation case analysis, deposition review and expert summary, evidence presentation, consulting, report writing, court exhibits, static and computer depictions, construction and engineering contract analysis, accident reconstruction, interpretation of administrative regulations for design and development, Earthquake Damage Assessment and Remediation, etc.

I package civil, mechanical engineering, as well as, general, engineering, earthwork and paving and hazardous waste contracting into one package for the use of my clients. Construction job site safety in fire prevention and personnel protection.

I will take whatever steps necessary to address any foreseeable issues in the case in order to inform clients and prevent surprises at depositions and at trial.
