Kansas City, MO – Custom Engineering, a premier consulting firm specializing in mechanical, electrical, plumbing, lighting, commissioning, and sustainable design, today announced the acquisition of Technology Integration Engineering: TIE Consulting, LLC, a respected provider of low-voltage systems engineering based in St. Louis.
For the immediate future, TIE will continue to operate as “TIE Consulting, LLC – A Custom Engineering Company.”
