About the company
Wiss, Janney, Elstner Associates, Inc. Princeton Office Division operates as a prime contractor delivering historic preservation, structural assessment, and architectural engineering services to the Smithsonian Institution under a single-award indefinite delivery contract (IDC) focused on museum and cultural facility maintenance and renovation. The Princeton Office is a division of Wiss, Janney, Elstner Associates, Inc., a for-profit architectural and engineering firm headquartered in Northbrook, Illinois, that specializes in engineering, architecture, and materials science services for buildings and structures.
The vendor's federal footprint is highly concentrated: all eight recent prime awards (100% of awards) flow to the Smithsonian Institution, with seven of those awards issued as task orders against IDC 33330220DF0010306, the Smithsonian's single-award historic preservation services vehicle. Combined potential value across all awards stands at $803 thousand, fully obligated. The Princeton Office competes in the full-and-open market with no set-aside designation across its recent work. Representative task orders include a $235 thousand delivery order for wisteria vine support repair (May 2024), a $225 thousand task order for museum building and plaza revitalization (March 2024), a $60.7 thousand task order for condition assessment of the Henry and Baird Memorials at the Smithsonian Castle (December 2024), and a $12 thousand delivery order to evaluate sculpture vibration for the Freedom 250 Grand Prix race (August 2026). The vendor also held an earlier task order for the renewal of the Bird House and Great Flight Aviary at the National Zoo in Washington, DC (February 2022, $98.9 thousand). Work is categorized under NAICS 236220 (Commercial and Institutional Building Construction) and PSC B—Architect and Engineering Services for Museums and Exhibition Buildings. Activity has been episodic — one award per year from 2020 to 2022, three in 2024, and one in 2026 — with no visible recompete cliff in the near term given the IDC's ongoing status as the Smithsonian's preservation services vehicle.
