I worked for the AV integrator and I helped build the demo conference room that was used as the template for Principal's Des Moines renovations that started around 9-10 years ago. Even at that time, Principal was fully invested in having every conference room support hybrid conferencing and they even moved the entire phone system to MS Teams and only Exec level would have a physical telephone (not sure if they were able to follow through with this - I laughed at the idea of telling people to get rid of physical phones, but now I use Cisco software for my work phone). I left the integrator shortly after installing that demo room but Principal saw the need for hybrid workforce way back then - yet another sign that they didn't know how to effectively manage a remote workforce.Principal has a LOT of real estate downtown. At least 4 buildings (not counting 801 Grand) that can hold probably 5k+ people
