Portland Tower

In 4-1/2 months, the Empirehouse glazing team completed installation of 45,216 square feet of window wall and 3,662 square feet of terrace doors at the 17-story Portland Tower luxury condominium project in downtown Minneapolis, MN.

185 ft liftThis downtown Minneapolis project was logistically challenged by its proximity to the new Viking Stadium in addition to the new Downtown East Commons Park, and other new commercial and apartment building work. All projects were under construction simultaneously with similar deadlines and within blocks of each other. Our glazing crew demonstrated tremendous teamwork by safely meeting aggressive schedules and site management challenges with no injuries. The Empirehouse Safety & Quality Coordinator held monthly audits on site which helped our glazing team reach the Gold Standard in safety.

Rather than standard windows, a window wall system was selected for this project to meet today’s increasing energy efficiency demands, especially for high rise construction. This system can accommodate a wide variety of glazing solutions and offers exceptional thermal separation of the framing materials. It is an architecturally appealing and versatile product -perfect for high rise residential living.
