Kiewit Infrastructure South Co

Kiewit Infrastructure South Co., a subsidiary of Kiewit Infrastructure Group Inc., operates as a prime contractor delivering heavy civil engineering and infrastructure construction services to federal agencies on a full-and-open, non-set-aside basis. The company is headquartered in Peachtree City, Georgia and serves as a for-profit, non-tax-exempt corporate entity with no SBA certifications across its recent award footprint.

Kiewit Infrastructure South Co.'s capability portfolio centers on large-scale design-build and fixed-price construction for transportation, utility, and facility infrastructure. Recent prime work includes a $260.6 million design-build contract awarded by the USDA Forest Service Region 8 on November 6, 2025, for reconstruction of the Virginia Creeper National Recreation Trail following Tropical Storm Helene damage, encompassing 31 trestle bridge rebuilds, trail treadway restoration, and watershed rehabilitation across an 18-mile section in Washington and Grayson Counties, Virginia, with ultimate completion by March 31, 2027. The company also holds a $90.3 million firm fixed-price contract from Kennedy Space Center awarded July 31, 2026, for design, procurement, and installation of approximately 26,000 linear feet of underground duct bank infrastructure and associated electrical distribution systems at Kennedy Space Center, Florida, with completion targeted for October 31, 2029. A third contract, $36 million from Naval Facilities Engineering Command awarded May 4, 2026, covers construction services to repair the 3rd Battalion Causeway at Marine Corps Recruit Depot Parris Island, South Carolina, including rehabilitation of a 4,500-foot roadway, replacement of two 84-inch culverts with bridges and channels, and utility relocation, completing by May 8, 2029.

The vendor's three recent awards span three distinct federal customers — the Department of Agriculture Forest Service ($260.6 million), NASA Kennedy Space Center ($90.3 million), and the Department of the Navy Naval Facilities Engineering Command ($36 million) — representing 100% of its $386.9 million recent combined potential value. All three awards are obligated in full. The vendor competes in heavy and civil engineering construction (NAICS 237990 and related codes) and repair or alteration of highways, roads, streets, bridges, and railways (PSC codes reflect two transportation-focused awards and one utility infrastructure award). A significant recompete cliff looms within the next twenty-four months: the Virginia Creeper Trail contract, valued at $260.6 million, reaches ultimate completion on March 31, 2027, and will face recompete before that date. On the Virginia Creeper project, Kiewit Infrastructure South Co. subcontracts with a multi-vendor team including Kiewit Engineering Group Inc. for design services, Inland Construction for bridge rehabilitation, Greenway Bridge LLC for timber bridge design and installation, Coastal Drilling East for micropile foundation installation, East Coast Rigging & Contracting Company for specialty rigging, and multiple other specialists covering occupational health, bridge painting, trail reconstruction, mechanical contracting, environmental consulting, and structural steel supply. Kiewit Infrastructure South Co. is a subsidiary of Kiewit Infrastructure Group Inc., which holds federal contract vehicles and serves as a broader federal prime contractor and grant recipient.
