Since 1981, AMSYSCO has supplied and engineered post‐tensioned concrete reinforcement for large general and concrete contractors. AMSYSCO is one of the largest suppliers of unbonded post‐tensioning of high‐rise towers in the United States.

Their core philosophy is satisfying their construction customers need for outstanding engineering services and product quality. Their manufacturing plant is certified by the Post‐Tensioning Institute in order to satisfy the specification by structural and architects.

AMSYSCO believes that developers and owners of high‐rise buildings will benefit from the use of unbonded posttensioned concrete. It can allow for thinner floors, reduced building weights, improved seismic behavior, better real estate operational metrics and lower HVAC/energy costs.

Please note that all heights shown in italics/red are estimated heights. These have been calculated based on known floor counts for the building, then extrapolated through analyzing typically hundreds of buildings of the same function on this database that do have confirmed heights. The user should be aware that non-standard building features, such as significant spires or raised entrances / podiums, may affect the accuracy of these estimations.
