We are Egan Glassworkers

Tuesday, August 24th, 2021

Fabrication services for commercial glass and glazing systems have been a part of our scope of work at Egan Company since 1998. The InterClad team’s glasswork can be seen across the Twin Cities and the Midwest, often in high-rise housing, office buildings, stadiums, hospitals, hotels, and government facilities.


Glassworkers prefabricate curtainwall, storefront, and composite panel systems used to enclose a building. Our glassworkers are all members of Local Union 1324. Within Egan’s InterClad prefabrication shop, glassworkers cut, prep, and assemble the curtainwall and composite panel systems. They frequently work hand-in-hand with other trades at Egan to provide the highest quality workmanship to our customers.

A+ Testing for InterClad’s Curtainwall Systems

Monday, January 4th, 2021

Quality assurance is a promise Egan Company continues to provide customers on every project from every team and business offering. From placing that last electrical plate over an outlet to testing the integrity of a building façade, Egan will ensure the utmost quality on everything we construct, install, or remodel. 

Recently, Egan’s curtainwall system manufactured by Erie Architectural Products for the Essentia Health Vision Northland project in Duluth, Minn., underwent a series of performance tests to ensure even the toughest environmental elements wouldn’t compromise the integrity of the system. Over the course of two full testing days and an additional week in -30 degree weather conditions, a full size mockup section of the system had to pass 17 performance tests before any of the 2,700 units (almost 200,000 square feet) of curtainwall could be installed on the project. 

An airtight chamber was constructed on one side of the curtainwall system. The first tests completed are the Static Air Infiltration and the Static Water Penetration tests. These set a baseline for all additional tests, and both of these tests are completed after every round of testing to ensure the performance has not been affected. If either of the tests were to fail, the entire testing process would need to start over. 

All curtainwall systems installed on any Egan project undergo field testing to assess proper installation. A lab test is unique and is typically conducted when the curtainwall system is custom-designed and fabricated for the job. This project, for Essentia Health located in Downtown Duluth, has very stringent structural and thermal requirements which necessitated the lab tests be performed prior to starting the project. The project is a $900M hospital tower, clinic, and outpatient center that will add approx. 942,000 sq. ft. to Essentia Health’s Duluth campus. 

Additional tests that the system had to pass included air from a large wind generator directed at the curtainwall as water is sprayed; this is the Dynamic Water Penetration test. Other tests that focus on the structural design and movement, both vertically and horizontally, place additional stress on the system. Finally, the lab created a temperature simulation in the airtight chamber that lowered the ambient temperature to -30 degrees; the crews were unsure if they’d be able to sustain the extreme temperature requirements since this is 10 degrees lower than a standard test. Thankfully,  the curtainwall system passed all performance tests and installation on the project can proceed as planned.

The curtainwall unit went through extreme conditions, not only extreme weather conditions, but structural and movement testing as well,” said Ryan Woodruff, Egan Company Vice President and InterClad Business Leader. “It was great to see our curtainwall pass all performance tests and solidify that we install some of the best curtainwall products in the Midwest.

Curtainwall performance tests included:

  1. Static Air Infiltration Test
  2. Static Water Penetration Test
  3. Dynamic Water Penetration Test
  4. Uniform Structural Design Load Test
  5. Repeat Static Air Infiltration Test
  6. Repeat Static Water Penetration Test
  7. Interstory Differential Horizontal Movement Test
  8. Repeat Static Air Infiltration Test
  9. Repeat Static Water Penetration Test
  10. Interstory Differential Vertical Movement Test
  11. Repeat Static Air Infiltration Test
  12. Repeat Static Water Penetration Test
  13. Thermal Cycling Test
  14. Repeat Static Air Infiltration Test
  15. Repeat Static Water Penetration Test
  16. Building Maintenance Equipment Load Test
  17. Uniform Structural Overload Test

Innovation and safety is the name of the game with Egan’s utilization of the new SpyderCrane mini lift. Identifying a need to install glass in a different way than before at a high-rise project, Egan’s InterClad and Safety teams brainstormed possible options. The innovative and compact SpyderCrane was the solution that fit the installation needed in the confined working area.

“Typically, Egan’s InterClad team utilizes a ground crane to install glass and windows in large high-rise buildings,” said Jason Lindula, Egan Company Safety Manager. “We now use the SpyderCrane to reduce material handling, create a safer installation process, and provide an opportunity for a smaller crew size.”

On a high-rise project jobsite, imagine the SpyderCrane on level six, two Egan employees on level five, and two Egan employees on level four. The SpyderCrane lowers the glass into place from above, allowing the Egan crews on the lower levels to install the glass into place quickly and safely.

Specifications of Egan’s SpyderCrane:

  • Capacity to lift 2,000 lbs.
  • Variable Geometry Outriggers – allows for lifts in tight spaces
  • Remote control and pressure sensitive controls
  • Narrow track width and low center of gravity

We’re still working out the kinks of utilizing a new piece of equipment,” said Ryan Woodruff, Egan Company Vice President. “But the SpyderCrane’s ability to install glass in tight spaces while we utilize additional installation tactics in other areas ensures we’re staying on track for the overall project.

With one SpyderCrane already active on a jobsite, a second SpyderCrane will be arriving soon for use on additional jobsites where confined installation is needed. The precision and safety of the SpyderCrane mini lift provides Egan an opportunity to increase accuracy and ensure safety while continuing to install glass on even the tallest high-rise buildings in the Midwest.

Discover Egan: Smartlift

Wednesday, October 25th, 2017

Designers in the glass industry are specifying larger glass units and pre-glazed windows for today’s buildings. Though aesthetically pleasing, these large pieces of glass can be extremely heavy to handle for installation. However, Egan’s InterClad team is prepared thanks to our investment in four of Smartlift’s 380 Midi’s – or as Smartlift affectionately calls it, one of its “highly efficient glazing robots.”

“The purpose of the Smartlift is to safely handle large, heavy items our tradespeople cannot on the projects where larger pieces of glass are involved,” said Tim Woolworth, Egan Company/InterClad Senior Vice President. “This helps prevent possible injuries that we are at risk for in our industry.”

Smartlift is the market leader and developer for intelligent lifting devices. Characteristics of the robot include:

  • Four suction cups to lift the large, heavy items
  • Hoist and move items up to 840 pounds (380 kg) over any surface
  • Multi-tasking capabilities: drive, hoist, extend, and tilt the attached glass unit simultaneously

A few of our projects that have utilized our Smartlifts:

  • 365 Nicollet
  • Legacy Condominiums
  • University of Minnesota Athletes Village
  • InterContinental Minneapolis-St. Paul Airport

The precision and safety of the Smartlift robot provides Egan an opportunity to increase accuracy and continue installing large glass units found on more and more buildings around the U.S.

Bringing fans to their feet

Monday, October 3rd, 2016

Towering nearly 30 stories high and covering about 200,000 square feet of the stadium’s exterior, the reflective glass and curtainwall of U.S. Bank Stadium is hard to miss. The interior boasts a flood of purple and gold, lush green turf, and multiple LED video boards. Football fans will be able to experience this all firsthand during the Minnesota Vikings’ first season at the new stadium.

The 1.75 million square foot facility will serve as the Minnesota Vikings’ official home, and also stands as a testament to the hard work of thousands of people, including Egan employees, who worked on site and behind the scenes to install the stadium’s curtainwall, glass/glazing, pivoting glass doors, and numerous LED displays inside and out.


Reflection of Our Work

The curtainwall boasts five operable walls/pivot doors spanning up to 95 feet high and controlled by hydraulic levers. These doors are able to shield spectators from harsh Minnesota weather when closed, while providing fresh air and exposure to the outdoors when open. Built into these doors are smaller storefronts – 10 for every larger door – which allow entry in all seasons.

In addition to installing 200,000 square feet of curtainwall, more than 5,000 pieces of glass were installed, some spanning over 200 feet tall and inverted at a 24 degree angle.

On sunny days, a distinct reflection of the Minneapolis skyline can be seen on the glass’ surface. Not only does the stadium show a mirror image of one of Minnesota’s most iconic cities, its unique architecture and design also serves as a reflection of the personality and identity of the community that surrounds it.

Engineering challenges related to the unique geometry of the curtainwall required careful consideration and planning throughout the project; scheduling and jobsite limitations made the role of prefabrication and coordination even more critical.

“The Vikings stadium has more unique geometry than we’d seen on past projects, and to a larger scale,” said Deb Linquist, Egan Company Senior Project Manager. “Through our quality control process, and our upfront work in the office, it was very critical that we provided proper fabrication packages with dimensions and details to the shop.”

The hard work paid off – Egan’s InterClad team won Glass Magazine’s Most Innovative Curtainwall Project for the stadium in July 2016.

Display of Collaboration

Inside the stadium, fans can watch 60-foot tall football players bound across an enormous video board more than 8,100 square feet in size. The display is the stadiums’ largest, and the tenth largest scoreboard in the NFL. At 68 feet high and 120 feet wide that’s enough space to park about one-and-a-half F-22 fighter jets.

Unlike other stadiums around the country, U.S. Bank Stadium does not have video boards hanging from the ceiling. Doing so would have compromised the amount of natural light and the indoor-outdoor feel the stadium provides.

Instead, they are installed significantly lower than most video boards in the NFL in order to allow fans to easily look from the field to the board, regardless of where they are sitting.

Partnering with Ssail LED video boardouth Dakota-based Daktronics, Egan installed more than 25,000 square feet of LED displays, including 19 LED video displays with 13HD technology that provides crisper and more vibrant images to the fans. The total square footage of LED displays is the most in the NFL.

In addition to the interior displays, Egan installed an outdoor marquee display, and a first-of-its-kind sail-shaped exterior video display that tops what the Minnesota Vikings call the “Legacy Ship.”

Our Stadium

The largest public works project in Minnesota history, U.S. Bank Stadium took 3.5 million man hours to complete – a massive undertaking equivalent to 1,700 years of full time work for one person. Throughout its construction, the project sustained the families of thousands of workers – and will help define the Minneapolis skyline for years to come.

It has helped bring major events to our state, including superstar concerts, charitable events, and Super Bowl LII in 2018. And many local restaurants and businesses now have the opportunity to provide their goods to a new audience base.

Take the “bank” out of U.S. Bank Stadium and you get a building named for us – not just the Vikings, or even the workforce that came together to turn the stadium into a reality, but all Minnesotans – and you don’t have to be a football fan to appreciate that.
