PSN Parsons Corporation

Parsons Corporation (NYSE: PSN) announced today that the company was one of 15 lead consultants selected by Los Angeles World Airports (LAWA) for a Multiple Award Task Order Contract (MATOC) to perform on-call, task order-based, professional services for LAWA’s Capital Improvement Program. The Program Services MATOC represents nearly $1 billion in contracting value over a term of five years and will serve both Los Angeles International Airport (LAX) and Van Nuys Airport (VNY).

LAWA’s Program Services MATOC is the largest award of its kind in the City of Los Angeles’ history and breaks inclusivity records that set new standards for local, diverse, veteran, small, and microbusiness participants.

"We are thrilled to have the opportunity to continue our longstanding partnership with LAWA, which began in the lead-up to the 1984 Olympics when Parsons provided design and construction services for LAX’s second-level roadway to increase ground traffic capacity and solve major access challenges," stated Catherine Cronin, senior vice president of Parsons' aviation sector. "For more than four decades, our team of aviation professionals has been dedicated to infrastructure projects at LAX, and we are honored to be part of one of the largest infrastructure projects in the United States – and part of renewed Olympic preparations in advance of the 2028 Games.”

Since 2017, Parsons has served as the project management/construction management (PM/CM) consultant and owner’s representative for LAX’s Landside Access Modernization Program (LAMP), which includes the Automated People Mover (APM), delivering the bid and procurement process for the APM’s development team selection.

Additionally, the Parsons-designed HireLAX Apprenticeship Readiness Program has played an integral part in LAWA's inclusivity initiatives. Launched in 2017, the program is a collaboration between public agencies, higher education, non-profits, unions, and the private sector that prepares local residents for skilled craft labor careers.
