New technologies are raising the bar on how tall buildings can go. But computer programs alone aren’t the answer. We believe that collaboration amplifies our innovative potential. It’s why we foster an open, communicative culture that empowers our teams to share knowledge and ideas across all levels and disciplines. That’s how we discover the right questions to ask – and answer. That’s how we keep our eye on the big picture. That’s how we redefine the possible.


Performance-based design (PBD) of high-rise buildings is a recent codified methodology that is renovating the structural design of high-rise buildings in earthquake-prone regions. PBD buildings meet the intent and performance objectives of the building code but are designed using a more rigorous approach that increases building performance reliability and enhances architectural flexibility.
