Photos: Construction Authority and Parsons staff hold kick-off meetings to begin design effort for Pomona to Claremont A Line Extension
The Construction Authority is holding kick-off meetings this week with Parsons, as they begin the design effort for the Pomona to Claremont A Line Extension. This follows last month’s award of a six-year, $60 million design and engineering services contract to the engineering firm, following a competitive procurement process that began in June 2025 and saw bids from multiple teams.
Over the next two years, Parsons will design all elements of the 2.3-mile light rail extension from its current design level of approximately 30% to “Approved for Construction” drawings. Once construction is underway, Parsons will also support the project with any needed design services over what is expected to be a four-year construction phase.
The design and engineering services contract is the first of two contracts needed to deliver the Pomona to Claremont A Line Extension using the Construction Manager at Risk (CMAR) delivery method. The second contract is for the contractor.
The procurement process to hire the contractor (called the construction manager with this delivery method) reached a major milestone earlier this month with the release of the Request for Proposals (RFP), following a successful industry review period of the draft RFP that was completed late last year.
The construction manager contract is expected to be awarded this coming May, and will include an initial phase of work during project design that includes providing constructability reviews, value engineering, third party coordination and cost estimating. Once the project reaches 85%-90% design, the winning contractor will have the possibility of building the project if the team successfully negotiates a construction services contract with an acceptable price. Assuming a successful bid for the construction work, it is expected that major construction will begin in late-2027/early-2028 and take about four years to complete.
