Thomas Mackey– 2015 Fall General Meeting Speaker Spotlight

Thomas Mackey
Mackey Consultants


Mr. Mackey grew up in the Southwest desert of Arizona. He moved to Flagstaff to attend college and graduated in 1977 from Northern Arizona University. He worked his way through college by working the summers in the cantaloupe packing sheds and fighting forest fires on a hot shot crew stationed in Arizona’s the Coconino National Forest. His career started in construction as a field engineer working on multiple construction projects. After he attained the required engineering training and experience, in 1982 he achieved the status of Professional Engineer in Civil Engineering. In 1988 Mr. Mackey started his own business which is now Mackey Consultants, LLC and TM Engineering. Mr. Mackey has a well-rounded background from working with the craft in the field to reviewing PhD level finite element computer models for compliance with strict nuclear regulations. While managing Mackey Consultants, LLC he also works for WRPS Hanford, provides engineering consulting to Mission Support Alliance, and provides independent design review for Washington Closure Hanford.

Some of his recent notable consulting tasks include the hoisting and rigging independent design review for lifting and transport of a 1,200 ton contaminated reactor, the independent “Critical Decision” structural review of the DOE Office of Science newly completed Pacific Northwest National Laboratory’s (PNNL) Capability Replacement Facility and provided structural consulting for the Canadian Atomic Energy of Canada Limited (AECL) Chalk River Nuclear facility.

Removal of the reactor is the heaviest lift performed in the history of the Hanford Site. The Capability Replacement Laboratory represents the largest construction project in PNNL’s 46-year history. This project was awarded the most successful DOE project of the year for completion under budget and within schedule. Mr. Mackey worked with AECL to identify the cause, in the software, that was generating computer errors while running the seismic response spectra subroutine in the finite element models.
