The MBTA Blue Line Extension Project involves designing and developing a construction plan for a new station at the intersection of Massachusetts Avenue and Newbury Street in Boston. This station will connect with the existing Hynes Station, improving accessibility and enhancing Boston’s transit network. The project focuses on constructing the platform, mezzanine, and entrances to a 15-20% design level, integrating structural, architectural, and geotechnical considerations. Key aspects include pedestrian flow optimization, ADA compliance, and space constraints in this high-traffic urban area. Beyond design, we are developing the construction methodology, sequencing, scheduling, and cost estimation to ensure efficient project execution. A key challenge is minimizing disruptions while delivering a cost-effective solution that optimizes the budget and timeline. Our goal is to create a realistic, well-coordinated plan that aligns with MBTA’s long-term objectives for an accessible, sustainable, and commuter-friendly station.
