Miyamoto provided Los Angeles World Airports (LAWA) with a series of options to retrofit the existing Delta Airlines office and hangar structure. This included adding 83,300 SF of office space in the existing hangar, currently unusable as a hangar facility. Miyamoto brought value to the client by using performance-based engineering to upgrade this essential facility building to performance level. Some of the latest technologies, such as buckling restrained brace frames or fluid viscous dampers (shock absorbers), were options provided. These options allowed for minimally invasive retrofit work in the office space and excellent performance in an earthquake, at a cost of $144 per square foot for an essential facility.
