David Ahearn

Biography

David L. Ahearn is a Senior Consultant with Engineering Systems Inc. (ESI), who performs scientific investigations and root cause analysis of failed components, structures, and systems. Common issues for analysis are determining contributions toward failure from design, manufacturing methods/material processes, use conditions, maintenance, or application. Investigations have included everyday items such as roadways and household items, to complex industrial material applications for refractory linings and computer components. In addition to components and structures, Mr. Ahearn has performed systems analyses for regulatory compliance, gap assessments, code and safety compliance.

Mr. Ahearn has over ten years of civil engineering experience and over five years of hands on construction and project management experience. As a civil engineer practitioner his experience included site design (buildings, roads, parking, utilities and accessibility), municipal planning, stormwater management, and water/wastewater treatment and piping. As a construction project manager he has worked ground up on many residential projects from new construction to remodeling and repairs. Mr. Ahearn has investigated failures of water distribution pumps/piping, building collapse, building moisture intrusion, concrete and precast concrete structures, foundations, and soil systems. In addition to construction methods, Mr. Ahearn is an active member of ANSI A10 committee on construction safety contributing toward increased workplace safety.

Mr. Ahearn has over 7 years materials science experience which has included materials characterization, materials testing, fractography and failure analysis of glass, ceramics, refractories, concretes, and coatings. Some example material applications have been cast-in-place and precast concrete, industrial refractory linings, glass and ceramic components, plumbing fixtures, pharmaceuticals, container glass, building glass, and industrial equipment components. Mr. Ahearn has performed hundreds of pharmaceutical manufacturing root cause investigations including tableted oral dosages, liquid oral dosages, and transdermal patches. Mr. Ahearn also has extensive experience analyzing coatings used for adhesives, paints, and sealants.
