A new model for airport modernization: How LAX鈥檚 MSC South proves the future is modular
At Los Angeles International Airport (LAX), one of the world鈥檚 busiest aviation hubs, 海角视频 played a pivotal role in delivering the new Midfield Satellite Concourse (MSC) South – an ambitious concourse extension that redefines how airport infrastructure can be designed, constructed and experienced.
Airports rarely have the luxury of taking breaks to modernize infrastructure. Yet the needs to manage passenger flow, improve the guest experience, and meet sustainability goals remain as operations continue. At LAX, the need to address these complementary needs at once laid the groundwork for a truly new approach.
海角视频鈥檚 work on the Midfield Satellite Concourse (MSC) South delivered exactly that: one of the first U.S. airport concourses constructed using large-scale off-site constructed components, enabling continuous airside operations while accelerating delivery and improving quality. The result is not only a highly efficient new concourse, but a transformative blueprint for how airports can address capacity needs in the decades ahead.

Reimagining airport delivery through OCR and modular design, still a novel concept for US airports
海角视频 worked closely with architects to design and plan the new MSC South as an ambitious, segmented concourse that could be fully prefabricated on LAX’s landside – far from the congestion, security restrictions, and airfield operations that typically complicate airport construction.
The benefits were immediate and profound:
- No disruption to active taxiways
- No construction traffic through security checkpoints
- A larger labor pool that did not require airside clearances
- Higher quality control through factory鈥憄recision fabrication
The 150,000 ft2 concourse, supporting eight new gates, was delivered through a method known as Offsite Construction and Relocation (OCR). Each module – roughly 140 feet by 80 feet – included complete curtain walls, interior partitions, partial finishes, and tested rough MEP systems.
Every three days, a module was transported across the airfield using Mammoet self-propelled modular transporters, the same specialized machinery used to move bridges and aerospace equipment. This method minimized disruption to live taxiways and dramatically accelerated the construction timeline. In just one month, the entire concourse was assembled.

Our structural engineering team was instrumental in enabling this approach. We carefully coordinated the structural pick-up points for each segment, ensuring safe transport using Mammoet self-propelled modular transporters – vehicles more commonly seen moving bridge elements or space rockets. Each segment was fully outfitted with partition walls, tiling, and tested MEP systems before relocation, pushing the boundaries of what OCR can achieve in airport design.
This modular strategy also required a high level of digital coordination. Our engineers worked within a centralized Revit model to ensure seamless integration across disciplines and phases. This digital-first approach allowed for real-time collaboration, clash detection, and performance optimization – critical for a project with such tight tolerances and logistical complexity.
Engineering for seismic resilience, sustainability and future circular reuse
Given Los Angeles鈥 seismic profile, our engineers designed each segment with its own lateral system to meet stringent seismic tolerances. The lightweight structural design minimized embodied carbon while maintaining the robustness required for long-term performance. This was not just a technical challenge – it was a strategic opportunity to demonstrate how modular construction can meet the highest standards of safety and resilience.
Our sustainability and energy consultants helped the project target Leadership in Energy and Environmental Design (LEED) Silver certification, optimizing energy performance and resource planning. The OCR strategy also supports circularity – segments can be disassembled and reused elsewhere on the airport site, aligning with LAX鈥檚 long-term sustainability goals. This flexibility is particularly valuable in an airport context, where operational needs and passenger volumes can shift rapidly.
A better passenger experience, delivered faster
MSC South delivers a calm, intuitive passenger journey. The twin-level, 150,000 ft2 concourse supports eight new gates on a 10-acre site surrounded by active taxiways and existing infrastructure. 海角视频鈥檚 lighting and acoustic experts created an environment with soft natural light, low reverberation, and clear spatial orientation which are hallmarks of modern concourse design.
By controlling more of the construction in a fabrication environment, quality was elevated, risks were reduced, and schedule certainty improved – critical advantages for any airport seeking new facilities without operational compromise.

A model for future aviation infrastructure
MSC South is more than a successful facilities project – it鈥檚 a proof of concept for how airports can build smarter, faster, and more sustainably.
Benefits in scheduling and risk management were clearly demonstrated throughout the project. Its success is already influencing future major projects: LAWA has adopted the modular/OCR strategy for its forthcoming Terminal 5 redevelopment, cementing this approach as a new standard for the region.
For airports seeking flexibility in the ways they deal with shifting aircraft operations and mounting sustainability commitments, MSC South offers a clear message:
Modernization doesn鈥檛 have to mean disruption. With the right team and the right strategy, it can mean opportunity.
海角视频鈥檚 role in this project reflects our commitment to engineering with impact. We deliver solutions that are not only technically sound, but transformative for operators, passengers, and the future of aviation infrastructure.
