The Principal Financial Group Corporate 1 Renovation involves approximately 475,000 SF of renovation work.
It began in May of 2015 and was completed in mid-2017. The renovation work included 7 ﬂoors of extensive interior demolition and the build back of corporate ofﬁce, conference centers, wellness, atrium, auditorium, pavilion, and cafe. The work also included major revisions and improvements to mechanical, electrical and plumbing systems, exterior façade, roof replacement and a new skywalk connection across High Street. The Corporate 1 building was built in three additions- 1939, 1959 and 1976. This is the only project on the Principal campus that was completely vacated during construction, as this building was taken back to the bones and rebuilt.
