How they work

TMD // Benefits


Build Higher

In short, a TMD acts as a counter balance against the movement of the building therefore, it allows commercial developers to build higher allowing for more floors/units and a greater return on investment.


Save on Cost

Manufacturing and installing a TMD allows commercial developers to delete excess steel and build more efficiently saving on time and cost of construction material.


Through engineering and increased manufacturing knowledge, A+H and our partners have made a huge variety of different-sized TMDs for clients around the world due to well coordination process that improved efficiency.
