Andrew Jenkins

Associate III

 
Experience

Andrew Jenkins has participated in and led in-depth investigations and rehabilitations of multiple concrete structures, including cast-in-place and precast buildings and bridges. These assessments have included various types of evaluations utilizing both destructive and nondestructive testing (NDT) and observation services during construction. Mr. Jenkins has significant experience with concrete placements and cast-in-place concrete and shotcrete over preinstalled waterproofing. He also provides training for best practices related to bridge girder erection plans and procedures.

Prior to joining WJE, Mr. Jenkins worked for the Kansas Department of Transportation, where he was involved with concrete materials research and provided technical field services. His projects there included evaluation of new concrete materials and test methods, condition assessments and failure investigations of pavements, bridges, and other transportation facilities, and concrete material and/or mix design services during construction, including guidance related to concrete material properties and proportions, specifications and/or materials testing.
