Blast systems blend with historic design on Fairfax courthouse

"Coordination between manufacturer, glazing contractors and consultants and designers was crucial to ensure proper anchorage and installation. We rely on a collaborative approach -- especially with projects like these -- to make it possible to complete construction, while maintaining the day-to-day operations of the facility." — Kevin Robbins, regional sales manager, Wausau Window and Wall Systems Inc.

The basics: The $105.7-million, expansion and renovation to Fairfax County's Jennings Judicial Center in Fairfax, Va., features a high-performance, blast-resistant curtain wall system that adheres to heightened security mandates and preserves the aesthetic integrity of the historical district. The 316,000-square-foot addition doubled the size of the existing building. The new facility consolidates the county's justice system under one roof and combines operations from the neighboring, historic Fairfax County Courthouse.
