Burns and McDonnell drew inspiration from helicopter motors and blades for aesthetics and a functional design for Minnesota National Guard's Arden Hills Army Training Site. It houses two units of the 834th Aviation Support Battalion, which specializes in maintaining Blackhawk and Chinook helicopters.

W.L. Hall Co. installed 9,000 square feet of Wausau Window and Wall Systems' 7250 Series SuperWall with 4250i-BHM INvent blast hazardmitigating windows. Burns and McDonnell specified laminated glass to mitigate hurricanes, bomb blasts and other hazards. Viracon Inc. supplied its laminated, insulated glass with Crystal Gray tint and low-E coating for the project.

Additionally, W.L. Hall Co. installed Tubelite Inc.'s Therml=Block entrance systems on the exterior and medium stile Monumental Doors at interior entrances. Linetec finished the curtainwall and storefront's aluminum framing in Class I clear anodize.

Arden Hills Army Training Site was sited with consideration for anti-terrorism and force protection setbacks. Eric Breidel, Wausau Window and Wall Systems' architectural sales representative in Minnesota, says as windows and curtainwalls encounter extreme pressures released by explosive masses, all elements of the assembly work together to withstand the blast load and dissipate energy. "Instead of the historical design practice of specifying thick windows with rigid frames, modern blastmitigating assemblies are intended to be flexible and absorb, rather than resist, blast energy."

The LEED Silver-certified military training facility was oriented east-west for southern daylight exposure and to reduce energy consumption. Breidel says recycled aluminum content was quantified to contribute to LEED certification. "While blast hazard mitigation was the major requirement, we also contributed to the project's green building goals with the daylight, views and high thermal performance with Wausau's window and curtainwall systems, as well as Tubelite's entrance systems," he says.

The site and facility act as a public interface for the complex. It is located on approximately 2,370 acres in the northern third of Arden Hills and features expansive views of rolling landscape and native plants. The $17 million, 64,000-square-foot project was completed in September 2015.
