DAE Sung LLC

DAE Sung LLC, a tribally-owned, minority-owned, self-certified small disadvantaged business headquartered in Plainfield, Illinois, operates exclusively as a prime contractor (100% of awards) delivering facilities maintenance, engineering, repair, and construction services to the federal government under the Total Small Business set-aside category. The vendor competes entirely within set-aside procurement vehicles and has never subcontracted federal work; across all 1,704 awards in the source, DAE Sung holds no sub-awards and maintains no named prime relationships as a subcontractor.

The vendor's customer base concentrates heavily on GSA Public Buildings Service. The top five customers by award count account for 82% of recent awards, led by GSA PBS Region 3 (412 awards, $129.1 million combined potential value), GSA PBS Headquarters (336 awards, $214.7 million), and GSA PBS Region 1 (308 awards, $277.7 million). However, the top-value ranking reverses the volume order: GSA PBS Region 1 anchors $277.7 million in combined potential value, followed by GSA PBS Headquarters at $214.7 million and Region 3 at $129.1 million. The Department of Justice Bureau of Alcohol Tobacco Firearms and Explosives accounts for $45.2 million across four awards. Together, these five customers represent 72% of all combined potential value across DAE Sung's federal footprint. The vendor's 60 distinct customer agencies and concentrated work with GSA regional offices reflect a narrow, highly specialized market position in federal real-property operations and maintenance.

DAE Sung's capability portfolio spans routine and emergency facilities maintenance: HVAC system replacement and repair (chillers, air-handling units, variable frequency drives, compressors), plumbing (pipe repair, sump pump replacement, backflow preventers, sewage ejectors, water distribution), electrical work (fire alarm systems, lighting, transformer maintenance, circuit breaker repair), roofing and structural repairs (leak remediation, shingle replacement, gutter restoration, concrete work), and specialized services including lead remediation, asbestos abatement, mold remediation, and building security infrastructure (access control, alarm systems, fire suppression). Representative work includes a $269.3 million comprehensive chiller overhaul and reconditioning at the Norfolk Federal Building (June 2026), a $310.1 million sanitary sewer line lining project at the Pierre Federal Building in South Dakota (September 2026), and a $183.5 million hot water coil replacement and repair project at the Iowa City Federal Building (September 2026). The majority of awards carry ceiling values between $3,000 and $50,000, representing routine call orders against standing blanket purchase agreements and the GSA Federal Supply Schedule. DAE Sung's largest single vehicle is a $50 million GSA Federal Supply Schedule contract (47QSMS24D0054, awarded March 25, 2024, running through March 24, 2029) covering facilities maintenance and ancillary services across the 48 contiguous states and Washington, D.C., with 28 labor categories spanning custodial roles at $31.94 per hour through supervisory maintenance positions at $112.05 per hour.

Activity has grown consistently year over year, from 77 awards in 2022 to 363 awards in 2026 (through October 15, 2026). This trajectory reflects expanding GSA regional engagement and deepening penetration within the public-buildings operations market. The recompete cliff identifies 156 awards with ultimate completion inside the next twenty-four months, carrying combined potential value of $11.7 million — a modest exposure reflecting the short-duration, call-order nature of most PBS work, which typically runs three to twelve months.

DAE Sung's vehicle position centers on the GSA Multiple Award Schedule, which carries 2,797 task orders worth $959.6 million in combined potential value — the overwhelming majority of the vendor's federal footprint. The vendor also holds a seat on the OASIS+ Total Small Business Set-Aside IDIQ (awarded October 17, 2025, running through October 16, 2030, with a multi-billion-dollar ceiling) and competes for Facilities functional-area task orders governmentwide. Recent awards also reference a 10-year Bureau of Alcohol Tobacco Firearms and Explosives BPA established September 1, 2026, with a $42.1 million ceiling running through August 31, 2036, also drawn against the GSA Multiple Award Schedule. Named regional BPAs appear across GSA's field offices, including a $63.9 million GSA Region 3 facilities operations BPA (covering Virginia, West Virginia, Maryland, Pennsylvania, and Washington, D.C., through October 31, 2032) and a $22.7 million North Carolina facilities BPA (ultimate completion July 31, 2034).

SCI-reported invoiced revenue on federal service contracts above the $150,000 threshold totaled $80.5 million across FY2022–FY2025: $4.1 million in FY2022, $13.8 million in FY2023, $31.9 million in FY2024, and $30.7 million in FY2025. The SCI dataset shows approximately 117 FTEs delivered to the federal government in FY2025, up from 11.9 FTEs in FY2022 — a tenfold scale-up in reported staffing. On federal service contracts captured in SCI, median government-paid rates ran around $77.91 per hour, with the 10th percentile at $61.69 per hour and the 90th percentile at $139.79 per hour, consistent with the GSA Schedule labor portfolio. Across SCI-reportable prime contracts, subs performed approximately 34% of total hours, with 45 total named subcontractors identified, indicating that DAE Sung builds most delivery teams in-house but engages specialized subcontractors for equipment installation, testing, and compliance work beyond core facilities operations scope.

DAE Sung operates through a corporate structure that includes VEL Tye LLC, a named subsidiary also designated as tribally-owned, minority-owned, and self-certified small disadvantaged. The parent-subsidiary relationship and overlapping ownership designations suggest operational alignment within a single enterprise focused on facilities maintenance and related services for federal facilities. The vendor's footprint is concentrated in the Mid-Atlantic, Southeast, and Northeast regions, with heaviest activity in Virginia, North Carolina, Maryland, Pennsylvania, Massachusetts, and Vermont, though task orders extend nationwide under the GSA Federal Supply Schedule and OASIS+ vehicles. DAE Sung competes exclusively under the Total Small Business set-aside designation and has not pursued full-and-open procurements, indicating a deliberate market positioning as a tribally-owned, small-disadvantaged business supplier focused on federal facilities maintenance rather than broader facilities engineering or design-build services.
