Project Description

Helping protect federal government offices and occupants in Puerto Rico, while preserving the Modern aesthetic, Wausau Window and Wall Systems provided high-performance systems for the Federico Degetau Federal Building and the Clement Ruiz Nazario U.S. Courthouse. Glazing contractor Koch Corporation of Louisville, Ky., installed six types of Wausau’s windows to meet the various security and environmental requirements including energy efficiency, ballistic and blast mitigation, and moisture and hurricane resistance.

The project was one of several funded in Puerto Rico by the Federal Government. The window replacement was funded as part of the U.S. General Services Administration’s (GSA’s) Security Enhancement, Glass Fragmentation Program.

Located on a 26-acre campus in the Hato Rey section of San Juan, the buildings represent the largest GSA-owned asset in the Caribbean. Federico Degetau Federal Building houses more than a dozen federal agencies. The imposing, seven-story, 460,000-square-foot structure features a steel-reinforced, poured-in-place, exposed concrete facade. Connected to the federal building with a 1,600-square-foot addition, Clement Ruiz Nazario U.S. Courthouse spans 100,000 square feet.

Both buildings were designed in the 1970s by local architects O’Kelly, Mendez & Brunner and Miami-based engineers Smith, Korach and Associates. The architectural style is described by some as “Brutalist Modernism.” To administer historically appropriate, exterior upgrades for both buildings, the GSA retained Wank Adams Slavin Associates LLP (WASA/Studio A) as the project architect. Weidlinger Associates was the structural engineer for the project.

According to Anna Raykis, PMP the project manager with the Design and construction Division of the GSA Public Building Service Northeast and Caribbean Region, the existing windows were original to the building and showed signs of significant deterioration. Raykis cautioned, “The performance criteria for these windows are not typical.”
