What LEO A DALY does
LEO A DALY is a U.S.-headquartered architecture, engineering, interior design, and program management firm founded in 1915 in Omaha, Nebraska, and operating as a limited liability company. Combined with its 1991-merged subsidiary Lockwood, Andrews & Newnam (LAN), the firm employs 850 professionals across 26 U.S. offices and delivers integrated multi-disciplinary design services across aviation, federal healthcare, civic, education, commercial, workplace, industrial, hospitality, senior living, and public safety market sectors. Its underlying technology stack centers on Building Information Modeling (BIM), CAD, VR visualization, simulation/energy modeling, climate resilience analysis, and data-driven planning for industrial facilities, supported by proprietary design methodologies including the Dignity Driven Design framework for senior living and the NIAC Four Rs resilience framework.
The firm operates a project-based professional services revenue model, earning fees through fixed-fee, percentage-of-construction-cost, or time-and-materials contracts; pricing is project-specific and not publicly disclosed, typically structured as multi-year engagements. Go-to-market is enterprise/field-sales driven, secured through competitive procurement (RFPs/RFQs), qualifications-based selection, and long-standing institutional relationships with federal agencies (notably the Department of Veterans Affairs and National Guard), healthcare systems, airports, universities, real estate developers, and corporate end-users. Named flagship engagements include the Ronald Reagan Washington National Airport terminal and ATC tower, VA community-based outpatient clinics, Cheney Brothers' hurricane-resilient food distribution center, the 660,000 SF Toro Company headquarters, and senior living communities such as Sinai Residences.
LEO A DALY was family-owned for over a century before completing a strategic partnership with Hennick & Company in September 2024, with 42 senior employees acquiring a 25% equity stake. It acquired San Diego-based Delawie in December 2025 to expand West Coast and hospitality/residential capacity. Combined revenues were $232 million for the 12 months ending February 29, 2024.
