Elizabeth Alexandra Sargent

Elizabeth Alexandra Sargent, doing business as LIZ Sargent HLA, a woman-owned small business sole proprietorship based in Charlottesville, Virginia, holds a $5 million multiple-award indefinite delivery contract with the National Park Service Southeast Region to deliver historic preservation, architectural, and engineering services as a prime contractor. All 19 awards in the source record are prime contracts; the vendor operates exclusively on the NPS side with no subcontract footprint or sub-award engagement. The firm is certified as a woman-owned small business and competes under total small business set-asides and woman-owned small business sole-source designations on most of its work.

LIZ Sargent HLA's capability portfolio is narrowly focused on cultural resources management, architectural documentation, and historic preservation engineering for federal historic sites. Work centers on historic structure reports (HSRs), condition assessments, structural monitoring, treatment planning, cultural landscape reports, National Register nominations, and compliance services at national parks and monuments across the southeastern United States and Caribbean territories. Representative prime work includes a $287 thousand firm fixed-price definitive contract awarded by NPS Southeast Region in June 2026 for historic structure reports on the Santa Elena Powder Magazine and Guardhouse at San Juan National Historic Site, Puerto Rico; a $252 thousand delivery order from December 2024 for HSRs of Quarters 209 and 210; a $226 thousand delivery order from January 2025 for architectural and engineering services stabilizing the Creque Marine Railway Head House at Virgin Islands National Park; and a $417 thousand delivery order from September 2022 for updating the HSR for Castillo San Cristobal in Puerto Rico with closeout services. The underlying $5 million IDIQ vehicle (awarded September 24, 2022, with ultimate completion September 23, 2025) has generated 10 task orders carrying $1.9 million in combined potential value and covers Interior Regions 2, 1 (Kentucky), and 4 (Mississippi and Louisiana), plus the South Atlantic Gulf region.

Customer concentration is extreme: the Department of the Interior National Park Service Southeast Region accounts for 100% of award count and dollar value through 14 awards totaling $7.3 million in combined potential value. The NPS Intermountain Region and a standalone NPS award contribute $56 thousand and $226 thousand respectively but represent a negligible portion of the portfolio. Five awards (combined potential value $1.1 million) have ultimate completion dates within the next twenty-four months, representing recompete exposure concentrated at a single customer. Activity was relatively stable in 2022–2023 (five and six awards respectively), then declined sharply to one award in 2024 and two in 2025. The most recent award (June 2026) signals continued NPS engagement but does not reverse the downward trajectory. NAICS concentration is 79% Engineering Services (15 awards), with four awards under Computing Infrastructure Providers and Data Processing; PSC coding reflects Architect and Engineering work.
