About Siris LLC
Siris LLC, a Service-Disabled Veteran-Owned Small Business headquartered in Mount Pleasant, South Carolina, delivers construction management, facility modernization, and professional staffing support services to civilian federal agencies as a prime contractor across a portfolio of 73 awards. The company is a veteran-owned, self-certified small disadvantaged business operating as a for-profit corporate entity with two named subsidiaries: SA3 Construction Management LLC and Providence CM Joint Venture LLC, both carrying SDVOSB designations.
The federal customer base is heavily concentrated in civilian infrastructure and museum work. The Smithsonian Institution accounts for 52 awards (71% of Siris's recent prime footprint) valued at $62.5 million combined potential value, anchored by a single-award Indefinite Delivery Contract awarded September 9, 2024, with a nominal one-dollar ceiling and performance extending through September 9, 2034. This IDV serves as the vehicle for ongoing construction management support services across the Smithsonian's real property portfolio, with delivery orders spanning museum facility upgrades, building envelope revitalization, collections preservation, and staff support. Named examples include a $3.05 million delivery order for National Air and Space Museum loading dock renovation, a $1.27 million delivery order for construction management support, a $620 thousand delivery order for veterinary hospital renewal at the National Zoo, and smaller-value task orders for emergency generator installation, wireless communications systems, sanitary system upgrades, and historic preservation staffing. The second-tier customer, the Department of Veterans Affairs, fragments across multiple subordinate organizations: the Technology Acquisition Center anchors two awards valued at $45 million combined potential value (a $44.9 million commissioning, re-commissioning, and retro-commissioning services BPA awarded April 30, 2026, with ultimate completion July 31, 2030, and a $29.5 million GSA Federal Acquisition Service call), and scattered VISN offices place smaller delivery orders for facility construction management, commissioning services, and temporary staffing. Together, the Smithsonian and VA account for 88% of recent awards.
Siris operates predominantly under the GSA Multiple Award Schedule, where 25 task orders carry $106.2 million in combined potential value. On the Smithsonian side, the vendor leverages the single-award IDV and two additional subordinate Indefinite Delivery Contracts (33330219DF0010311 and 33330224DF0010395) for 24 and 21 task orders respectively, totaling approximately $57.8 million. Activity has accelerated in recent years — four awards in 2023, five in 2024, and 15 each in 2025 and 2026 — positioning the vendor for sustained engagement across both customer bases. Eighteen awards (combined potential value $17.8 million) reach ultimate completion within the next twenty-four months and face recompete exposure.
Siris's capability portfolio, grounded in its award history, centers on construction management, project management, and professional staffing for federal facility modernization. Work product includes design manager support (MEP), Building Information Modeling, cost estimating, scheduling, procurement support, staff augmentation, commissioning and retro-commissioning services, collections preservation and decontamination, historic preservation support, and temporary staffing for financial and electronic health record systems modernization. The company does not subcontract; all 73 awards are prime awards with no sub-award footprint captured in the source. Siris operates exclusively as a prime across its federal portfolio.
Service Contract Inventory reporting, which captures federal service contracts above the $150,000 threshold, shows limited depth: $1.2 million in total SCI-reportable invoiced revenue across FY2022–FY2024 (zero invoicing in FY2022, $466 thousand in FY2023 across 1.9 FTEs, and $742 thousand in FY2024 across 2.6 FTEs). This represents a small fraction of Siris's total federal services footprint and reflects SCI's exclusion of firm-fixed-price task orders, goods, and products. On SCI-reportable prime contracts, median government-paid rates ran around $135.66 per hour, with the spectrum spanning $123.91 at the 10th percentile to $152.63 at the 90th percentile. The company's GSA Schedule portfolio spans 23 labor categories with hourly rates from $45.34 (Data Entry Clerk) through $186.90 (Project Executive), positioning Siris to staff roles across project management, engineering, architecture, cost estimating, and administrative support functions with education requirements ranging from none to bachelor's degree and experience from entry-level through ten-plus years; no security-cleared labor categories are offered.
The recent award trajectory shows consistent growth and customer concentration risk tied to the Smithsonian's decade-long IDV commitment. Siris competes predominantly full-and-open under civilian agency vehicles rather than set-asides, though its SDVOSB designation recurs across VA commissioning and construction management work. The company's capacity to sustain high-value Smithsonian engagement depends on task order flow under the single-award IDV through 2034; no comparable anchor vehicle exists with the VA, which has historically placed lower-ceiling orders across multiple contracting offices. Recompete cliff pressure is moderate at $17.8 million over the next twenty-four months, concentrated in Smithsonian delivery orders and VA VISN task orders.
