When people think about engineering on a military base, they often imagine runways, hangars, or large-scale facilities. What they don’t always see is the infrastructure that keeps everything moving, securely, efficiently, and without disruption. That’s exactly where O’Brien Engineering’s work at Lackland Air Force Base, part of Joint Base San Antonio, comes in.

Designing a First Point of Entry
At Lackland Air Force Base, OEI led the full architect-engineer (A/E) design for a Commercial Vehicle Inspection Facility (CVIP), along with improvements to the Entry Control Point and expanded inbound lanes. On the surface, that might sound like a simple checkpoint, but it’s anything but. This is a critical access node for the base, where security, operations, and traffic flow must work together seamlessly.
The design includes:
- A commercial vehicle inspection area
- A visitor control center
- Gatehouse and support facilities
- Overwatch functions and secure access elements
- Expanded vehicle staging and inbound lanes
Each piece has a role, but the real challenge is making them all function as one coordinated system.
Where Architecture Meets Operations (and Security)
Projects like this are a good reminder that architecture isn’t just about buildings. It’s about how people, vehicles, and systems move through space.
At Lackland Air Force Base, OEI focused heavily on:
- Controlled circulation for both vehicles and personnel
- Efficient vehicle processing and inspection flow
- Clear separation between public, controlled, and secure areas
- Functional relationships between facilities to minimize bottlenecks
At the same time, the site design had to tie utilities, paving, drainage, parking, fencing, and signage into a single, functional environment. It’s the kind of project where site, buildings, and operations can’t be designed in isolation.
Solving Real-World Constraints
One of the biggest drivers on this project was addressing existing issues with vehicle queuing, traffic flow, and inspection capacity. Translation: things were backing up, and the system needed to work better.
OEI’s design responded by:
- Expanding and reorganizing inbound lanes
- Improving channelization and staging areas
- Designing facilities that support faster, more efficient inspection
- Creating a layout that can handle higher traffic volumes safely
And all of this had to happen while maintaining strict security requirements. No shortcuts.
Designing Within Military Requirements
Another layer of complexity comes from working within Air Force criteria and security standards (including UFC and AT/FP requirements).
That means every design decision, from layout to materials to circulation, has to support:
- Controlled access
- Security and safety
- Operational reliability
It’s not just about making something work; it has to work predictably, securely, and under pressure.
Coordination Is Crucial
Like most federal projects, this wasn’t a single-discipline effort.
OEI coordinated across:
- Architecture
- Civil engineering
- Structural systems
- MEP systems
- Security design
Working closely with base stakeholders, the team used design charrettes and phased submittals to refine the layout and keep everything aligned with mission needs. The goal was simple: no surprises during construction and no disruptions to base operations.
Keeping Lackland Air Force Base Running During Construction
One of the more interesting parts of the project is something most people never think about: How do you build or upgrade a critical access point without shutting it down? OEI addressed that by developing phased construction and traffic control strategies, including temporary access routes and detours. That planning helps ensure the base can continue operating normally, even while major improvements are underway.
What Success Looks Like
At the end of the day, success for a project like this isn’t flashy; it’s functional.
The final design:
- Improves safety and traffic flow
- Reduces delays in vehicle processing
- Supports secure, controlled access
- Creates a scalable solution for future needs
It’s a behind-the-scenes improvement that makes a very visible difference to daily operations.
Projects like the Growdon CVIP at Lackland Air Force Base highlight something OEI focuses on across all federal work: The best engineering solutions aren’t just technically sound; they’re practical, integrated, and built around how people actually use the space. Whether it’s a military installation, healthcare facility, or a single secure entry point, the goal is the same: design environments that perform under real-world conditions and support the mission every day.
