Mystic Lake Center 

Mystic Lake Center is a 70,000-square-foot event center and a 180-room hotel tower featuring 18 new suites with scenic views. Combining this expansion project with the existing Mystic Lake Casino Hotel makes it the second-largest in the Minneapolis-St. Paul area. Empirehouse entered into design-assist services with PCL Construction to assist with budgeting, pre-engineering, and the design layout anchoring of the saw-tooth curtainwall attachment.

On-Site Pre-Glazing

Entering the project at the beginning of the design phase helped Empirehouse utilizes its Project Managers, Field Superintendents, and Glazing foreman to come up with an innovative on-site pre-glazing plan. It worked to doubled efficiency and reduced equipment costs and lift-related injuries for the nine-story hotel tower featured approx. 25,000 square feet of 6″ curtainwall assemblies glazed with high-performance glass. Empirehouse also participated in enclosure meetings early on with other Project Managers to hash out critical details on the exterior skin of the building prior to field mobilization, and a full-sized mockup was created to ensure system constructability.

After the Empirehouse production team fabricated the aluminum frames and delivered them to the job site, Empirehouse Glaziers set up two staging areas to pre-glaze curtainwall sections on site. When one section was pre-glazed it was hoisted to the opening by a custom picking beam and Spyder Lift Crane and installed by a team of Empirehouse Glaziers as the other curtainwall section was being pre-glazed on the second stage. After the first unit was installed, an Empirehouse foreman folded up and transported the Spyder Lift Crane above the second staging area to crane the other pre-glazed curtainwall unit to the opening for installation. It was a quicker approach than setting each frame separately using a swing stage to set the frames and glass into place. It also reduced equipment costs and kept the field crew productive with little downtime. In addition, Empirehouse utilized the Spyder Lift Crane to do the heavy lifting of other items like setting steel-loaded curtainwall mullions. This paid dividends in time savings as well as eliminating lift-related injuries.

Teamwork and Creative Glazing

In order to meet the Mystic Lake Center project Super Bowl deadline, our Field, Fabrication, and Project Management Team applied creative glazing and installation strategies to accomplish more work safely in less time. Empirehouse field team members utilized innovative pre-planning, teamwork, and creative glazing when they brought together a choreographed dance of three boom lifts and 12 Glaziers to install 190 glass lites into the facing hotel tower curtainwall on a sunny, summery Saturday.

During the week, glass units were crate dollied and skip stationed to each floor opening in preparation for installation. Then on Saturday, three teams of two Glaziers worked from the boom lifts and three teams of two Glaziers were stationed inside the building. One team prepped glass units, the second team set glass units, and the third team bolted frames. Working this way saved the time of moving the boom lifts up and down nine stories. Care was taken in coordination and planning so that there wasn’t a lift installing glass units over another glazing team to ensure safety on site.

In all approx. 3,500 square feet of glass lites were safely installed by the Glazing Team in one day!

Installing Electrochromic Smart Glass

The “swoosh” curtainwall lining the event center of the Mystic Lake Center project offered challenges of another kind. Approx. 10,000 square feet of 10.5″ curtainwall assemblies were glazed with Sage electrochromatic smart glass. This state-of-the-art programmable glass automatically tints as the sun moves across the sky. Hotel and event guests can enjoy uninterrupted scenic views without the sun’s glare, while it provides a comfortable controlled climate by blocking heat-gain during the summer months which reduces cooling costs. To make this electrochromatic smart glass function properly, each unit needed to be carefully wired, tested, and glazed perfectly into a unique frame location. This required an organized communication strategy. Project Assistant Rachel Yechout created an elevation to relay Sage wiring instruction procedures to the Fabrication and Installation Teams as they tested each glass tag.
