John E. Pearson

Principal and Laboratory Manager


Since joining WJE in 1990, John Pearson has worked on a broad range of assignments for stadiums, parking garages, buildings, building components, masonry and stone facades, bridges, and heavy machinery. His work has focused on the testing and instrumentation of structures and structural components. Mr. Pearson has developed and installed numerous computer-controlled data acquisition systems, which involved monitoring fatigue stresses in a dredge and a die-cast press, and vibrations and displacements in buildings and bridges. he has extensive experience in performing laboratory tests on various structural materials and elements, including post-installed mechanical and adhesive anchorage systems.

Mr. Pearson has coauthored papers and presented on structure response during the reconstruction of an underground utility, soil anchor testing and behavior, fatigue monitoring of a barge mounted excavator, full-scale load testing of a post-tensioned elevated roadway, post-installed concrete anchorage testing and evaluation, and bearing failure of a passenger train elevated bridge. Mr. Pearson has investigated the cause of an elevated passenger rail system and designed a bearing repair to mitigate future failures.
