Heather K. Todak

Senior Associate


Since joining WJE in 2016, Heather Todak has worked on numerous projects involving concrete assessment and repair design, structural evaluation, and nondestructive testing. Her work has involved both existing or historic structures and construction period services.

Ms. Todak specializes in the application of nondestructive evaluation techniques for the assessment of concrete and masonry structural elements. She is an experienced practitioner in the fields of ground-penetrating radar, impact echo, ultrasonic shear wave tomography, and ultrasonic pulse velocity. Ms. Todak has investigated, tested, and provided repair recommendations for bridges, high-rise concrete structures, parking structures, post-tensioned concrete structures, water and wastewater treatment infrastructure, pavements, foundations, and historic buildings.

She is affiliated with several nondestructive testing related committees and subcommittees with the ACI, including technical committees 228 and associated subcommittees through which she has assisted in the development of ACI documents and certification programs. Ms. Todak currently serves as Chair for the ACI 228-0B subcommittee for Visual Condition Survey of Concrete and serves on the board of directors for the ACI Southern California Chapter.
