At A&H, our passion is Tuned Mass Dampers (TMD's)!   With eleven TMD's in New York City alone, A&H has fabricated and installed more tuned mass dampers for buildings in North America than any other firm in the world.  Our TMD's can also be found on many new and historic bridges throughout Ontario.

Our facilities allow us to deliver a one-stop solution.  With in-house drafting, welding, machining and TMD assembly, we have a hands on approach during the entire project, allowing the client to see their TMD fully assembled on our shop floor prior to delivery to site.
