About the company
Siris LLC, a Service-Disabled Veteran-Owned Small Business headquartered in Mount Pleasant, South Carolina, operates as a prime contractor delivering construction management, project management, and professional staffing support to federal civilian agencies, primarily through the GSA Multiple Award Schedule and agency-specific IDIQs and blanket purchase agreements. The company competes predominantly on full-and-open construction and facility modernization work, with SDVOSB set-aside designations characteristic of its recent awards.
Siris LLC's customer concentration is bimodal: the Smithsonian Institution anchors activity volume (58 awards, $64.8 million combined potential value across 88% coverage of awards), while the Department of Veterans Affairs dominates potential dollars through three recently awarded blank purchase agreements and IDIQs carrying $677.9 million in combined ceiling value. The VA Technology Acquisition Center alone accounts for a $631 million construction management and project management BPA issued August 14, 2026, a $44.9 million commissioning and retro-commissioning services BPA, and related task orders. The Smithsonian's 58 awards are granular delivery orders under a single-award IDC with a nominal $1 ceiling, established September 9, 2024, and running through September 9, 2034, covering museum facility upgrades, building envelope revitalization, collections preservation, and infrastructure work across multiple properties in Washington, DC and field stations nationwide. GSA Federal Acquisition Service carries a $29.5 million potential value through Siris LLC's Schedule position.
Recent named work demonstrates Siris LLC's capability framing: a $1.93 million SDVOSB set-aside delivery order with VA Technology Acquisition Center for EHRM infrastructure upgrades construction management at the Tampa VAMC (issued August 26, 2026); a $1.30 million SDVOSB set-aside delivery order with Veterans Integrated Service Network 2 for EHRM PM/CM support at Brooklyn VAMC (August 4, 2026); a $3.05 million delivery order with the Smithsonian for National Air and Space Museum loading dock renovation (January 6, 2026); multiple construction management support delivery orders ranging from $17,434 to $2.44 million across Smithsonian museum sites; and a $1.11 million definitive contract with the VA Office of Construction and Facilities Management for construction management at IGAP (April 15, 2024). The source references prior high-value work including a $13.9 million National Air and Space Museum Building Envelope and Infrastructure Revitalization project and a $1.91 million Hirshhorn Museum and Sculpture Garden revitalization.
Siris LLC places 28 task orders under the GSA Multiple Award Schedule (MAS), carrying $740.5 million combined potential value—nearly all of which flows through the recent VA BPA ceiling values. The vendor also holds three Smithsonian IDCs (IDIQ Nos. 33330219DF0010311, 33330224DF0010395, and F08CC10461) with 51 combined task orders valued at approximately $64.8 million. The top parent vehicles reflect the MAS concentration: MAS hosts 28 orders; the Smithsonian IDIQ 33330219DF0010311 carries 24 task orders for $49.9 million; IDC 33330224DF0010395 carries 27 orders for $10.2 million.
Activity has accelerated sharply. Awards per year moved from 4 in 2022 to 24 in 2026 (year-to-date as of late September 2026); the most recent award is dated September 29, 2026. Seventeen awards (combined potential value $16.9 million) reach ultimate completion inside the next twenty-four months and face recompete exposure. The combined potential value across all 83 awards stands at $835 million, with $55.8 million obligated as of the source date (7% of potential value), reflecting the backlog of unexercised ceiling capacity across the newer, larger VA vehicles.
SCI-reported invoicing on federal service contracts above the $150,000 threshold totaled $3.3 million across FY2022–FY2025, with $2.1 million invoiced in FY2025 across 7.7 FTEs. This represents a partial slice of Siris LLC's federal services activity and does not reflect the firm's full enterprise revenue. Median government-paid rates on SCI-reportable contracts run around $135.66 per hour, with the spectrum spanning $123.91 to $152.63 per hour. Across SCI-reportable prime contracts, Siris LLC self-performs 100% of labor (0% subcontractor hours share).
Siris LLC's GSA Schedule labor portfolio spans 23 categories at $45.34 to $186.90 per hour, including data entry clerks, project schedulers, cost estimators, project managers, senior architects and engineers, and senior project managers. No security clearances are required across the posted labor categories; education levels range from high school to bachelor's degrees. The company operates as a prime contractor on 99% of recent awards (82 of 83), with minimal subcontracting footprint (1 named sub award to CB Design Group, Inc. for cost estimating support on a VA EHRM design project, October 2022).
Corporate structure includes two named subsidiaries: SA3 Construction Management LLC, certified as a Service-Disabled Veteran-Owned Business and self-certified small disadvantaged business; and Providence CM Joint Venture LLC, a SDVOSB joint venture. The summary characterizations in the source—particularly regarding Siris LLC's historical execution on National Air and Space Museum and Hirshhorn projects—anchor the vendor's positioning in federal facility modernization and construction management, though the award detail in the source reflects activity primarily from 2022 forward.
