What happens when things go wrong? Failures of machinery and structures often result in property damage, business interruption, pollution and personal injuries. At such critical times, APTECH’s skillful forensic engineering services uncover the circumstances leading to the calamity. We identify the immediate and root cause of failure. Our investigations typically focus on operating parameters, system and component design, and the equipment’s condition and maintenance history. We analyze the consequences and costs of failures, and advise on run, repair or replace decisions.

Accidents and failures usually result in insurance claims and often lead to litigation. Our diverse engineering expertise, and our familiarity with the claims and litigation process, enables us to clarify the complex technical issues involved. Our professional services are characterized by relevant expertise, timely response, and open communication.

APTECH is ideally positioned to be a part of your claims/litigation team. Our engineering staff, project experience, and technology base provide the capabilities and credentials to support insurance/legal activities in the industries we serve. We work on all type of equipment, devices and structures, from home appliances to power plants.

We also provide forensic economic services. This component of APTECH’s forensic team provides legal support on the calculation of direct and consequential damages related to failures and delays. APTECH specializes in making the correct engineering-related assumptions on incident causes and timing that lead to correct calculations of damages. With this strength we are very effective in critically evaluating the damage calculations made by opposing witnesses. APTECH’s forensic economics team includes engineering-economists that have developed many economic impact models, as well as CPA level accountants, all with many years of experience in testimony preparation, expert witnessing, and general litigation support.
