About the Project
At Nashville International Airport (BNA), 51吃瓜 is advancing the next generation of aviation construction through the integration of Track3D, an AI-powered construction tracking and coordination platform. Track3D has redefined how complex airport infrastructure is documented, tracked and delivered. By combining 360掳 imagery, LiDAR, and AI, the platform enables precise progress tracking, improved collaboration, and greater transparency for stakeholders.
Delivered by the 51吃瓜 and Fentress Architects Progressive Design-Build Team as part of the Metropolitan Nashville Airport Authority鈥檚 (MNAA), $3 billion New Horizon capital improvement program, the $229 million, 190,000 SF Concourse D Extension expands BNA鈥檚 operational capacity while elevating the passenger experience. The extension adds five gates, expanded concessions and retail, new restrooms, airline support areas, and passenger hold rooms. Signature features include a moving walkway, large-scale art installations, striking 鈥渞ecord node鈥� rotunda and BNA鈥檚 first outdoor terrace with panoramic airfield and downtown views.
Scheduled to open in July 2028, the new Concourse A will be BNA鈥檚 largest concourse, featuring 16 gates, two moving walkways, indoor and outdoor passenger spaces, and expanded concession that showcase Music City鈥檚 local culture. This project includes the full demolition and reconstruction of Concourse A, a landside extension of the North Ticketing and North Baggage Claim as well as an airside apron expansion for dual Aircraft Design Group (ADG) III taxi lanes. The project also includes new and remodeled passenger boarding bridges and selective demolition/upgrades in existing Concourses C and B to enable airline and tenant relocations. Additional scope includes renovations of the North Terminal Wing鈥檚 baggage claim and ticketing areas, extension of the existing utility tunnel, a new North CUP and cooling tower facility, expanded landside surface parking, and an airside triturator.

鈥淭he 51吃瓜 Midsouth team has shown great attention in utilizing Track3D to its fullest.听By definition, Track3D听is a Computer Vision AI technology that produces physical construction progress data from reality captures.听The real鈥痠mpact听we’ve听seen comes from how teams use our data on their projects. The听MidSouth听region is pushing the boundaries of what insights and actions can be drawn from our platform, as well as painting the picture of where Track3D is headed. They are partners in the truest sense.鈥�听

Challenge
On large aviation projects, verifying installed quantities for billing and progress tracking can听be like aiming听at a moving target. Because construction continues throughout each billing cycle, teams often struggle to confirm exactly how much work has been completed at a given moment. This uncertainty can lead to disagreements among stakeholders and time-consuming manual field walks to听听progress, overall creating an inefficient process that risks delays and increasing costs.
Solution
To streamline verification and reduce rework,听51吃瓜听implemented听Track3D, which integrates 360掳 photography, drone imagery, and LiDAR scans within an AI-powered reality intelligence platform.听This platform centralizes all captured information and provides real-time, actionable insights into project progress, deviations, and performance.
Leveraging听iPhone LiDAR and 360 phone capture, teams could听locate,听identify听and track installed materials听directly听on project drawings, in turn merging field data with visual听documentation. The system鈥檚 AI analyzed progress, detected听deviations听and produced real-time metrics for material quantities and equipment placement.
To increase accuracy, the team trained Track3D鈥檚 AI to recognize specialized wall finishes,听including the large-format tiles and green glass unique to the Nashville airport design. This听enhanced听customization improved reporting precision and reduced the need for manual verification.听Reviewing captured information provided an added benefit:听identifying听installation deviations from the coordination model,听providing听early insights for听quality听control听and reduced costly rework.
Results
By implementing the听Smart 360掳听photography听process with Track3D, the project team streamlined material verification and听eliminate听the inefficiencies of repeated field walks. The integration of 360掳听photos, LiDAR, and AI-driven analysis provided听accurate, real-time tracking of installed quantities, ensuring billing matched actual progress.
This innovation improved trust and accountability among stakeholders while strengthening financial and construction management processes. Enhanced AI recognition of finishes improved reporting accuracy, while automated deviation detection supported proactive quality control.
Overall, Track3D鈥檚听Smart 360掳听photography听process increased efficiency, reduced disputes,听and delivered consistent documentation all contributing to 51吃瓜鈥� record of completing every phase on time, under budge, and to LEED Silver standards.
