WISS, JANNEY, ELSTNER ASSOCIATES, INC.

WISS, JANNEY, ELSTNER ASSOCIATES, INC. specializes in forensic architectural and structural evaluation, repair design, and construction management for federal historic and mission-critical buildings. The firm delivers expert analysis of building envelope systems, masonry deterioration, structural integrity, and facade performance, often serving as the technical authority for complex preservation and rehabilitation projects. Their work includes detailed condition assessments, material testing, load-path analysis, and the development of code-compliant repair designs for limestone colonnades, brick coursed walls, gutter systems, and collapsed structural elements. They frequently serve as expert witnesses in litigation support for infrastructure disputes, combining engineering rigor with architectural precision to resolve high-stakes asset integrity issues. The contractor maintains a consistent relationship with the General Services Administration, delivering specialized architectural services for federal courthouses, administrative buildings, and historic federal centers across the country. They also support the Department of Transportation on infrastructure appeals and concrete performance evaluations for bridges and roadways, demonstrating adaptability between building and civil infrastructure domains. Their work for the Department of State and Department of Justice reflects a trusted role in securing and restoring federal property with cultural, legal, or diplomatic significance. Primarily engaged under NAICS 541310 (Architectural Services), the firm operates at the intersection of historic preservation, structural engineering, and construction oversight. Their market positioning centers on forensic architecture—identifying root causes of deterioration and delivering technically defensible, code-compliant solutions for aging federal infrastructure. They complement this with limited engagement in management consulting and physical science research, reinforcing a niche focus on building performance diagnostics.

The firm maintains a national footprint through project-based deployments, serving federal clients from coast to coast without reliance on geographic preference programs, positioning itself as a subject-matter expert rather than a small business participant.
