Louviere Stratton & Yokel LLC

Louviere Stratton & Yokel LLC, doing business as LSY Architects & Laboratory Planners, is a woman-owned small business providing architectural, engineering, laboratory planning, and construction administration services to federal research and healthcare agencies as a prime contractor (98% of recent awards). The company is a for-profit limited liability partnership headquartered in Silver Spring, Maryland, with a subsidiary structure that includes LSY-GES JV, LLC (a small business joint venture). The vendor competes predominantly in full-and-open procurements; recent awards carry no set-aside designations, though the company holds multiple total small business set-aside IDIQs and places occasional task orders under set-aside vehicles.

LSY's customer concentration is heavily weighted toward the National Institutes of Health. The top five customer agencies account for 68% of combined potential value across all awards. NIH Construction dominates the portfolio with 61 awards and $425.9 million in combined potential value, anchored by a single-award Indefinite Delivery Contract (NCI OSFM AE Services) valued at $6.3 million awarded September 24, 2026, with a ceiling running through September 2031 and an anticipated $1 million in annual task order volume. The NIH Office of Research Facilities Development Operations Acquisitions account for 28 awards and $51 million in potential value. The National Institute of Standards and Technology follows with 29 awards and $25.1 million, and the Food and Drug Administration with 55 awards and $12.3 million. A single Department of Interior Fish and Wildlife Service IDV awarded September 23, 2022, contributes $50 million in potential value through September 2027. These customer relationships span NAICS 541330 (Engineering Services) and NAICS 541320 (Architectural Services) across PSC C219 (Architect and Engineering—General).

LSY's vehicle portfolio centers on master agreements tied to specific agencies. The top parent vehicles by task-order volume are the NIH Architect Engineering MATOC (149 task orders, $195.2 million combined potential value), a DOI Architecture and Engineering Services MATOC 2022-2027 ($50 million, single award to LSY), an FDA multiple-award IDIQ (49 task orders, $10.8 million), an NIST multiple-award IDIQ (45 task orders, $50.8 million), and a USDA Nationwide Small Business A-E Services vehicle (28 task orders, $5 million). The bulk of LSY's work flows through task orders against these indefinite delivery vehicles rather than through direct solicitations or GWACs.

Representative prime work demonstrates capability scope. A $4.867 million delivery order from NIH Construction (awarded September 26, 2025, under the NIH Architect Engineering MATOC) covers Cup Expansion and Electrical Upgrades Project design and engineering with completion in February 2029. A $573,785 order from the same vehicle addresses Building 35 and 35A exterior envelope and leak repairs at the NIH Bethesda campus (ultimate completion November 1, 2026). A $579,185 delivery order from NIH Construction covers design and post-design services to remediate water intrusion in Building 31-B, extended through August 2027 to address design comments. A $373,609 firm fixed-price definitive contract from the U.S. Geological Survey (awarded September 20, 2024, under total small business set-aside) delivered a feasibility study and master plan for modernizing the Eastern Ecological Science Center at Patuxent Research Refuge in Laurel, Maryland, completing May 2025. Recent smaller orders include a $334,704 delivery order from the National Institute of Diabetes and Digestive and Kidney Diseases for Building 38 design and post-design services (September 30, 2026, completion June 2027) and a $258,947 delivery order from the National Cancer Institute for Building 37 vivarium air handling units replacement design (September 24, 2026, completion March 2027).

Activity has fluctuated over the past five years, with nine awards in 2022, a decline to two in 2023, recovery to eleven in 2024, five in 2025, and nine in 2026. The vendor faces a modest recompete exposure: eleven awards with combined potential value of $4.2 million reach ultimate completion within the next twenty-four months. The newly awarded NCI OSFM single-award IDV ($6.3 million, running through September 2031) and the NIST multiple-award IDIQ ($9.8 million, total small business set-aside, through September 2027) represent the most substantial vehicle positions awarded in the recent window.

LSY operates primarily as a self-performing prime. Across SCI-reportable prime contracts (a strict subset of federal services revenue, covering awards above the $150,000 threshold), the vendor invoiced $992 thousand from FY2022 through FY2025—$516 thousand in FY2022, $319 thousand in FY2023, and $157 thousand in FY2024, with no FY2025 invoicing in the SCI dataset. The SCI record shows minimal FTE activity: 0.1 FTEs in FY2022, 1.7 in FY2023, and 0.8 in FY2024. On federal services contracts captured in SCI, government-paid hourly rates ranged from a 10th percentile of $65.08/hr to a median of $78.29/hr, with a 90th percentile reaching $2,928.63/hr (likely reflecting subject-matter expert grant review or specialized consulting). Across SCI-reportable prime contracts, subcontractors accounted for an average of 12% of total contractor hours, with three named subcontractors engaged over the reporting period. This narrow SCI window does not represent LSY's full federal services revenue or total workforce; the company's prime federal contract footprint is substantially larger, with 432 total awards and $829.4 million combined potential value.

In its subcontractor role, LSY performs architectural and laboratory planning design services under Burns & McDonnell Engineering Company, Inc. on USDA Agricultural Research Service projects, including design work on the USDA Research Lab campus in Columbia, Missouri (awarded March 26, 2025), the USDA ARS Poultry Research Lab (March 5, 2025), and the USDA ARS Laboratory Campus in Auburn, Alabama (August 19, 2025). LSY also delivers laboratory planning and design support to Burns & McDonnell on next-generation laboratory design initiatives and the Department of Homeland Security Detection Sciences Testing and Applied Research Transportation Security Laboratory campus design (January 30, 2026). The sub-award footprint is minimal (2% of total recent awards) and concentrated under a single prime.
