PROJECT DESCRIPTION

The MBTA is installing three new accessible transfer elevators to service the Red and Orange Line platforms at the Downtown Crossing/Park Street hub station. The project includes the construction of an elevator lobby and machine rooms, the addition of a new underground corridor, replacement of several stairways, and façade improvements at the new elevator locations.

HDR |City Point Partners is providing cost estimating services and developing Contract Time Determination (CTD) schedules for the construction of these upgrades. We developed and are regularly updating the design schedule as well. During construction, we will provide schedule update review, independent cost estimates and time impact analysis of potential change orders.

Project Description

This new bus maintenance facility in Quincy is replacing the MBTA’s existing bus maintenance facility, the oldest in the MBTA system.

The existing facility lacked the technology and space to support the new Battery Electric Buses (BEB’s) that the MBTA is instituting to lessen the environmental impact. The new facility will be 350,000 sf and consist of four interconnected structures for the storage and maintenance of 120 buses with 11 service/maintenance bays, and offices. Specialty MEP and building communications systems infrastructure are required, as well as unique building equipment and restrooms, locker rooms, and vertical transportation.

During the design phase, HDR | City Point Partners provided cost estimating, scheduling, and public outreach services. During the construction phase, we are reviewing the contractor’s monthly schedule updates and coordinating and scheduling the testing and commissioning activities as an on-site office engineer.

PUBLIC OUTREACH

Project Description

City Point Partners is providing cost estimating and public outreach support during the design and construction for the replacement of this bridge built in 1925 which spans existing MBTA tracks including the Red Line, commuter rail, and freight rail service. The Dorchester Avenue bridge, with heavy vehicular traffic, is a very congested site, requiring full bridge closure and detour. All rail services must remain operational during construction and the Von Hillern Street retaining wall also needs to be protected and supported during construction. Additionally, the project will add a commuter rail track serving the Old Colony line.
