Mall of America Office Tower

The recently completed office tower at the Mall of America expansion was part of the most significant Mall construction projects since its grand opening in 1992.

With an aggressive completion date and challenging logistics, Empirehouse entered into a design-build/value-engineered contract with Mortenson Construction to meet the owner’s challenging needs.

The ten-story office tower balances the flanking twelve-story hotel and is connected by decorative glass “Jewel Box” on the building’s exterior. The view of these two connected structures provides the customers and clients of the MOA an amazing image as they enter from the busy I-494 freeway system. The striking office tower features the penthouse and stair areas cladded with approximately 13,000 total square feet of a four-sided structural silicone glazed aluminum pressure-wall framing system, glazed with a high performance low ‘e’ coating on the #2 surface with a stainless steel warm-edge spacer. The fourth through ninth floors have 25,000 square feet of ribbon curtainwall system glazed with matching glass. The accompanying spandrel glass was provided with the ceramic spandrel frit on the #3 surface, offering a subtle banding effect around the perimeter floors of the building. All aluminum framing was painted with a 3 coat custom fluropolymer finish.

Mall of America Office TowerA unique feature using curtainwall systems was utilized on the penthouse level. An oversized “railing” was designed to wrap around the perimeter corners to provide a wide-open exterior space for building tenants to enjoy warm weather socializing.

Mall of America Spider HydraLift wall climberComplex site conditions required sophisticated lift equipment. The glazing team utilized a Spider HydraLift wall climber, eight swing stage systems, and the Mortenson tower crane to scale the wall elevations and move and install frames and glazing.

Adding to the aggressive schedule and complexity of the curtainwall, the Mall of America remained open during construction. Our team was on constant alert for cars and pedestrians in order to keep everyone safe while meeting the project timeline and project goals.
