In 1998 SOA designed the PSRS/PEERS’ (Public School and Education Employee Retirement Systems of Missouri) original 50,000 square-foot office building. The building remained in good shape, but was ready for renovations due to aging HVAC systems, organizational re-structuring, and growth. In 2015, PSRS/PEERS first approached SOA for preliminary planning services, including a cost comparison of renovation and addition vs. a new replacement facility. In 2019, the board voted to proceed with SOA to design a complete interior renovation and 24,000 square-foot addition.
