The Midfield Satellite Concourse (MSC) South project is being built using a first-of-its-kind technique called Offsite Construction and Relocation (OCR), which allows for segments of the project to be constructed at a different location before being transported to the final site for installation. Construction of the nine segments began earlier this year just north of LAX’s northern runways and outside of the airfield operations area, allowing for an unprecedented level of operational flexibility and workforce inclusion, with minimal impacts to airport operations.

The third of nine segments was successfully delivered with overnight relocations of the remaining six segments continuing throughout the month. Once all nine segments are in place, project crews will assemble them together and continue construction at the site through 2025.

“Just nine months after its Groundbreaking, Woods Bagot is proud to have played a part in this cutting-edge building technique that is setting the bar for world-class design, and how sustainable design can drive better outcomes at airports and cities at large,” said Ian Lomas, Principal in Charge of Woods Bagot Los Angeles studio.

Each scheduled segment relocation begins around midnight, following the temporary closures of Runways 24R and 24L. Segments transported using two Self-Propelled Modular Transporters (SPMT) from Mammoet, which are carefully placed under each side of the segment. After final checks and verifications, the segment begins its 1.75-mile trip to the project site at a speed of approximately 1.5 miles per hour, escorted by LAWA and project staff members in vehicles and on foot who are also monitoring for foreign object debris or possible unforeseen issues. The runways are immediately reopened following thorough inspections by LAX Airport Operations staff.

“LAX’s modernization applies to more than just the projects we build, it includes taking on bold and modern construction methods like Offsite Construction and Relocation that will enable us to deliver incredible facilities like MSC South, while saving time and money, and allowing us to create jobs for our local workforce,” said Michael Christensen, Chief Airport Development Officer, Los Angeles World Airports. The construction team delivering MSC South under General Contractor W.E. O’Neil is comprised of local workers, with more than 30% representation from Los Angeles’ workforce. Because the segments were constructed using the OCR method, contractors were able to include workers who may not have been eligible to perform work on an active airfield.

Upon the project’s completion, MSC South will serve as an extension of the West Gates at Tom Bradley International Terminal, offering approximately 146,000 square feet of space and eight gates for narrowbody aircraft. These gates will help accommodate aircraft unable to park at other locations due to ongoing construction or other circumstances. The project is targeting LEED Silver.
