DAE Sung LLC

DAE Sung LLC, doing business as DAE Sung Of Illinois, LLC, operates as a tribally-owned, minority-owned, self-certified small disadvantaged business (SDB) providing facilities maintenance, engineering, repair, and construction services to federal civilian agencies as a prime contractor under the Total Small Business set-aside category. Headquartered in Plainfield, Illinois, the company competes exclusively in set-aside procurements across its federal footprint—all 1,574 recent prime awards carry Total Small Business designations. The company includes a subsidiary, VEL Tye LLC (also tribally-owned and minority-owned), expanding its operational capacity within the federal ecosystem.

DAE Sung's capability portfolio centers on facilities operations and maintenance across HVAC systems, plumbing, electrical work, roof repairs, emergency remediation, and building infrastructure upgrades. The past eighteen months reflect sustained activity in preventive maintenance and emergency repair work: representative prime awards include a $232.6 thousand oil-line repair at a federal facility in Norfolk, Virginia (GSA Public Buildings Service, June 2026, firm fixed-price BPA call), a $149.8 thousand sanitary-sewer modification and gate-valve replacement at the Alton Lennon Courthouse in Wilmington, North Carolina (GSA Public Buildings Service, April 2026), and a $142.8 thousand HVAC replacement contract at Richmond IT closets in Richmond, Virginia (GSA Public Buildings Service, February 2026). Across the full dataset, the top NAICS categories are Facilities Support Services (1,403 awards) and Commercial and Institutional Building Construction (127 awards), with PSC concentration in Housekeeping—Facilities Operations Support (693 awards) and Maintenance of Office Buildings (567 awards).

Customer concentration is heavily weighted to GSA Public Buildings Service across five regional offices and the headquarters organization. The top five customers by award count (covering 82% of recent awards) are GSA PBS Region 3 (412 awards, $129.1 million combined potential value), GSA PBS Region 1 (302 awards, $273.7 million), GSA PBS Region 4 (278 awards, $65.6 million), GSA PBS headquarters (228 awards, $168.1 million), and GSA PBS Region 6 (67 awards, $62.3 million). The potential-value ranking aligns closely with award count, with Region 1 anchoring both metrics. The concentration reflects DAE Sung's positioning as a regional and national facilities contractor under GSA's stewardship of federal civilian real property, particularly at courthouses, federal office buildings, and other public facilities.

DAE Sung holds a multi-billion-dollar parent vehicle portfolio. The cornerstone is the OASIS+ Total Small Business Set-Aside IDIQ awarded October 17, 2025 (contract ceiling $999,999,999,999, performance through October 16, 2030), a GSA-administered governmentwide vehicle spanning seven functional domains; DAE Sung qualifies to compete for task orders in the Facilities functional area across all federal agencies. The company also operates a $50 million GSA Federal Supply Schedule contract (47QSMS24D0054, effective March 25, 2024, through March 24, 2029) covering comprehensive facilities maintenance, management, and ancillary repair and alteration services across the 48 contiguous states and Washington, D.C. The schedule carries 28 labor categories with hourly rates from $32.18 (Laborer/Janitor) to $112.90 (Supervisor Maintenance Senior), reflecting entry-level custodial roles through skilled trades such as electricians and HVAC mechanics to supervisory positions—no security-cleared roles are offered. Beyond these two primary vehicles, DAE Sung operates multiple regional Blanket Purchase Agreements: a $14.7 million BPA for Vermont facilities (October 1, 2023, through January 31, 2033), a $22.7 million North Carolina facilities BPA (ultimate completion July 31, 2034), and a $63.9 million BPA for GSA Region 3 operations and facilities engineering services covering Virginia, West Virginia, Maryland, Pennsylvania, and Washington, D.C. (ultimate completion October 31, 2032). The Multiple Award Schedule itself generated 2,533 task orders worth $945.2 million in combined potential value, demonstrating saturation utilization across the GSA regional footprint.

SCI-reported invoicing (federal service contracts above $150,000) totaled $49.8 million across FY2022–FY2024, split as $4.1 million in FY2022, $13.8 million in FY2023, and $31.9 million in FY2024—showing strong upward trajectory. On federal services contracts captured in SCI, the vendor deployed roughly 11.9 FTEs in FY2022, 39.6 FTEs in FY2023, and 110 FTEs in FY2024, demonstrating rapid workforce scale-up. Government-paid median rates on SCI-reportable prime contracts ran around $89.10/hr, with the 10th percentile at $60.19/hr and the 90th percentile at $146.33/hr. Across SCI-reportable prime contracts, an average 34% of contractor hours were performed by subcontractors, with 30 named subs engaged over the dataset period; the vendor thus operates as a hybrid—building its own delivery teams for core scope while routinely engaging specialized subcontractors for component work.

Activity has accelerated dramatically over the past five years, rising from 77 awards in 2022 to a peak of 312 in 2024, before moderating to 233 year-to-date in 2026. A recompete cliff of 162 awards (combined potential value $8 million) will reach ultimate completion within the next twenty-four months, presenting both pipeline risk for DAE Sung and competitive recompete opportunity for rivals. The vendor operates exclusively as a prime on its recent federal awards—zero sub-award activity appears in the source—positioning it as a generator of work for its supply chain rather than a feeder to larger integrators. This posture, combined with Total Small Business set-aside predominance and regional GSA concentration, signals a company with deep expertise in facilities operations but limited diversification across agency base, service lines, or contract vehicle types outside the GSA ecosystem.
