4+ years supporting Great Hall and MOD 3 construction phases
Zero injuries to AAS personnel throughout the project
Hundreds of daily contractor access checks during peak periods
Secure-area oversight inside an operating airport terminal
Multi-phase coordination across shifting construction zones
The Great Hall and MOD 3 projects were multi-year redevelopment efforts conducted inside one of the busiest airports in the world. Construction occurred alongside daily passenger movement, TSA operations, and live airport activity.
Work zones shifted frequently. Access points changed. Crews rotated daily. Passenger pathways evolved. The operational and safety risks were high.
AAS was engaged to provide secure-area oversight, access control, safety observation, and coordination across multiple construction phases—ensuring construction progress did not disrupt airport operations or compromise traveler safety.
The environment required a partner who understood:
- Secure-area operations inside an active airport
- Federal compliance and airport security protocols
- Constantly changing construction zones
- Contractor access management at scale
- Coordination between construction, airport ops, and security teams
- Documentation and inspection readiness
DEN construction leadership needed a partner who could:
- Enforce restricted-area access consistently
- Support safe construction activity inside live terminals
- Coordinate contractor movement without disrupting passengers
- Adapt coverage as zones opened, closed, or shifted
- Maintain compliance-ready documentation
- Communicate clearly with primes and airport stakeholders
People
- Secure-area access control staff
- Safety and fire-watch observers
- Construction-zone escorts
- On-site supervisors coordinating daily coverage
Operations & Coordination
- Credential checks and controlled entry points
- Restricted-area enforcement
- Construction-zone safety monitoring
- Movement and pathway support for crews and passengers
- Daily reporting and communication with GC and airport teams
RESULTS EXPEREINCED
Across the Great Hall and MOD 3 phases, AAS helped maintain predictable, compliant construction operations inside an active airport terminal. General contractors consistently cited AAS’s reliability during early-morning mobilizations, crew rotations, and shifting access points.
Airport partners reported fewer unauthorized access attempts and improved coordination between construction teams and airport operations. AAS teams remained injury-free throughout the project and were recognized for calm communication, situational awareness, and anticipation of changing site conditions.
SAFETY & RELIABILITY
AAS delivered continuous secure-area support without operational disruption—maintaining full compliance and zero injuries across multiple years of construction activity inside a regulated, high-visibility environment. Operating inside a live airport requires judgment, discipline, and coordination.
This project demonstrates AAS’s ability to support secure construction inside environments where operations cannot stop.
For future team members, this work represents hands-on experience inside one of the country’s most complex airport redevelopment efforts. For partners, it reinforces AAS’s capability to perform in secure, mission-critical environments.
