About the company
SLS Federal Services LLC, a Galveston-based limited liability company and subsidiary of Slsco, LTD., operates as a prime contractor specializing in large-scale border security construction, competing under no set-aside designation and holding a dominant single-customer relationship with U.S. Customs and Border Protection.
SLS Federal Services LLC holds a $6.636 billion multiple-award IDIQ from CBP (awarded October 31, 2025, performance through October 30, 2030) under the DHS CBP Southwest Border Construction 2025-2030 vehicle, with three delivery orders issued to date. The firm's entire recent award footprint consists of four prime awards, all from CBP, totaling $9.92 billion in combined potential value, with $2.38 billion obligated to date. Customer concentration is absolute — CBP accounts for 100% of both award count and potential value. Work is grounded in concrete border infrastructure: a $2.214 billion firm fixed-price delivery order for border wall construction in the TCA-5 tonnage sector (completion September 14, 2027, place of performance Tucson, Arizona); a $683.5 million delivery order for vertical barrier construction in Encinal, Texas (completion August 31, 2028); and a $382.3 million design-build delivery order for waterborne and vertical barriers at Del Rio and Carrizo Springs, Texas (completion August 30, 2028). All three delivery orders are firm fixed-price and carry no set-aside. NAICS coding shows all four awards under Commercial and Institutional Building Construction; PSC coding aligns all four under Construction of Other Non-Building Facilities.
One award with combined potential value of $2.214 billion reaches ultimate completion within the next twenty-four months, creating significant recompete exposure in the near term. The vendor's parent, Slsco, LTD., is listed as a for-profit organization based at the same Galveston address and holds federal contract prime awardee status independently, suggesting a structured corporate relationship with potential operational or holding-company framing.
