What Ardurra does

Ardurra Group, Inc. is a U.S. multidisciplinary engineering services firm headquartered in Tampa, Florida, providing planning, design, and program/construction management for public and private infrastructure projects. The firm organizes its offering into nine core market services (Water/Wastewater, Transportation, Public Works, Environmental, Aviation, Civil, Aquatics, Emergency Management, and Transit) supported by five enabling capabilities (Surveying, Structural, Community Relations, Landscape Architecture, and Geospatial). Its technical scope spans water and wastewater treatment plant design, stormwater and flood control, roadway and bridge engineering, airport terminal and runway programs, environmental permitting and ecosystem restoration, and specialized aquatic life-support systems for aquariums and marine facilities.

The firm operates as a private equity-backed roll-up platform owned by Littlejohn and built through serial acquisitions of regional engineering firms (Fulghum MacIndoe, Gunda, T-O Engineers, WK Dickson, Cannon & Cannon, Janus Research, J.R. Wauford, Perteet, MKN, RVE, Kelly Engineers, and others) since 2021. As of mid-2026, Ardurra reported more than 2,600 employees across over 120 offices nationwide and ranked among the top-75 ENR engineering firms, with marquee engagements including the $2.3B Southeast Louisiana Urban Flood Control Program for the U.S. Army Corps of Engineers, the FEMA-funded $810M Bay Park Sewage Treatment Plant, and NOAA Pacific Regional Center facilities.

Ardurra monetizes via project-based professional services contracts procured primarily through competitive bidding by federal, state, and municipal agencies, supplemented by direct enterprise engagements (e.g., Ford, Disney, Ripley's). Pricing is negotiated per engagement and not publicly disclosed. Go-to-market is sales-led and enterprise-oriented, relying on the firm's ENR credentials, ACEC awards, project portfolio, BidDocs procurement portal, and an integrated platform structure that allows cross-region deployment of multidisciplinary teams on multi-hundred-million-dollar programs.
