Principal Corporate 1

The Principal Financial Group Corporate 1 Renovation involves approximately 475,000 SF of renovation work. It began in May of 2015 and is scheduled to be complete in mid 2017. The renovation work includes 7 floors of extensive interior demolition and the build back of corporate office, conference centers, wellness, atrium, auditorium, pavilion and cafe. The work also includes 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 will be completely vacated during construction, as this building will be taken back to the bones and rebuilt.
