Controlled Construction Enclosures for Active Airport Terminal Expansion at BWI Airport
Inside Look
Keeping Construction Moving Inside an Active Airport
At Baltimore/Washington International Airport (BWI), Clark Construction took on the A/B Connector project—an upgrade that needed to happen without shutting anything down.
Passengers still moving. Flights still boarding. Operations running nonstop.
And right in the middle of it—construction.
To make it work, Clark needed more than just a containment solution. They needed control over the environment, the schedule, and the safety of everyone in the space.
That’s where RWES came in.
The Challenge: Building Without Disruption
This Isn’t a Normal Jobsite
Working inside an active airport comes with zero margin for error.
-
Dust can’t escape into public areas
-
Noise has to stay controlled
-
Safety is under constant scrutiny
-
Work zones are tight and always shifting
-
Delays aren’t just costly—they disrupt operation
Clark Construction needed a way to keep work moving without impacting passengers, staff, or timelines.
The Solution: Controlled, Enclosed Work Zones
Creating Order in a High-Traffic Environment
-
No weather-related downtime
Crews worked through changing conditions without losing time. -
On-schedule delivery
Controlled environments reduced delays and kept the project moving forward. -
Improved jobsite safety
Built-in barriers and separation minimized risk for both workers and passengers. -
Better working conditions
Crews operated in a more comfortable, predictable space—boosting efficiency and morale. -
Smarter use of space
The enclosure doubled as a meeting area and even a projection surface for daily planning.
This wasn’t just containment—it was a better way to run the jobsite.

A Major Milestone: Transitioning to Final Phases
From Controlled Build to Finished Space
By January 2025, the project reached a key milestone. With the structure enclosed and conditions stabilized, Clark was able to remove the RWES system and move into final construction phases.
That included installing finishes like terrazzo flooring and completing the connector between terminal areas.
Because the environment was controlled from the start, the transition was smooth—with no costly setbacks or delays.
Why It Matters
Control Is What Keeps Projects Moving
On high-traffic projects like airport construction, things can go sideways fast.
Dust spreads. Work stops. Schedules slip.
Clark Construction avoided all of that by creating a controlled, predictable environment from day one.
RWES didn’t just support the project—it helped make it successful.

Airport
Main Purpose
RWES provided a conditioned, safe space where crews could work, hold stand-downs, and conduct foreman meetings, even using it as a projector screen, all while allowing the airport to stay fully operational.
Project Timeline
2023-2025

Having the RWES allowed safety stand down meetings and morning foreman's meetings to be conducted in conditioned space. The RWES even was utilized as a projector screen in the morning foreman's meetings to facilitate discussion of ongoing items.
