What Flintco, LLC does

Flintco, LLC is a U.S. commercial construction general contractor founded in 1908 in Tulsa, Oklahoma, operating today as a subsidiary of Alberici (acquired 2013). The firm delivers preconstruction, construction management, self-perform capabilities, and real estate investment services across market sectors including healthcare, higher education, sports, hospitality, K-12 education, Native American tribal nations, justice, aviation, public service, and renewable energy. Flintco is ranked #36 in the 2024 ENR Top 400 Contractors and reports $27B+ in cumulative completed project value, a 71% repeat client rate, and approximately 80 office locations with licenses in approximately 350 state jurisdictions.

The company differentiates through a combination of process methodology, technology integration, and self-perform capacity. Its proprietary Lean2.0 approach, claimed to deliver 90% of projects on or ahead of schedule, pairs with Virtual Design and Construction (VDC), Building Information Modeling (BIM), Target Value Delivery (TVD), StructionSite photo documentation, and AI-driven tools (SmartTagIt, Firmus, DestinI, Join). The Oakridge Builders subsidiary provides in-house steel fabrication, concrete, excavation, and other self-perform trades. Safety performance is a stated operating pillar, with a 2025 EMR of 0.52 (approximately half the industry average), 2024 recordable incident rate of 0.19, and 2024 lost time incident rate of 0.00, supported by consecutive ABC National Pinnacle Safety Awards (2023-2025).

Flintco generates revenue through project-specific commercial construction contracts, including CM at Risk, Design-Build, General Contracting, EPC, and Public-Private Partnership delivery methods, with pricing determined by competitive bids, negotiated contracts, or public procurement. The go-to-market is enterprise field sales managed through regional business development teams, supplemented by joint ventures with other general contractors (notably Mortenson on the approximately $900M+ OKC Thunder Continental Coliseum arena), the BuildingConnected trade partner platform, and a dedicated Trade Partner Portal. Flintco has worked with 78 Native nations and maintains 50%+ average tribal utilization on tribal projects, a distinctive capability in the U.S. commercial construction market.
