CitiMortgage Office & Data Center

O’Fallon, MO

Fortress of Technology.

The precision execution of one of the largest design/build electrical contracts locally earned PayneCrest an AGC Keystone Award for its work on the 515,000-square-foot CitiMortgage Office & Data Center. Armed only with architectural plans and no electrical drawings, PayneCrest’s on-site CAD trailers became the project’s nerve center. The trailers churned out more than 150 intricate drawings over a 90-day period to create a fortress of technology that handles 85% of the data that flows through the world’s largest bank.
