Principal Corp 2

Principal Corporate 2 is an 11 Story approximately 400,000 SF office building that includes a cafeteria, indoor parking and a locker room facility with two basketball courts.

The project includes a complete refresh of all of the open office floors, including complete demo of the restrooms and in interior finishes.  It includes new restrooms on each floor and adding a kitchenette to each floor along with mechanical upgrades and new conference rooms. We also refreshed the locker rooms and fitness area with new ceilings and carpet along with refinishing the basketball courts. A couple of the challenges on this project was trying to mitigate the stack effect that was going on in the high rise building.  It made the building very inefficient, to mitigate that we worked with our mechanical partners to alter some of the sequences of the fans and mechanical systems.  We also had to cut exploratory holes in the exterior walls to see if the insulation behind it had fallen down or had holes in it.  We were successfully able to mitigate this problem and make the building positively pressured.  Another challenge was moving the cafeteria from the 3rd floor down to the 1st floor so the 3rd floor could be returned to open office and match the other floors.  This activated the first floor and give PFG employees a chance to enjoy the atrium space and enjoy the newly renovated plaza.  It also allowed PFG to better use their space and fit more employees into the building.
