SYSTRA offers extensive capabilities in construction management ranging from major facility construction and rehabilitation, to new start rail lines and system modernizations. SYSTRA construction managers, resident engineers, and inspectors are familiar with the specifications and operation of equipment for rail and transit maintenance facilities, all types of track construction (conventional, concrete, direct fixation), stations, signaling, traction power, and communication systems giving us unique qualifications in the inspection, testing, and equipment start-up requirements of construction management.
Our construction managers have the experience, tools, and computer knowledge necessary to provide our clients with a project controls infrastructure and documentation that not only allows a real time, definitive picture of project status, but also provides solid support for claims and disputed items during and after the project construction phase.
From major facility construction and rehabilitation to New Start rail lines and system modernizations, SYSTRA offers extensive construction management capabilities. Many of our construction managers, resident engineers, and inspectors are former railroad employees familiar with the specifications, functions, and challenges of meshing construction projects with railroad operations. They are also uniquely qualified in the inspection, testing, and equipment start-up requirements necessary for new starts or system expansions.
Our comprehensive construction management services include:
- Resident engineering
- Construction inspection
- Change order processing
- Constructability review
- Shop drawing review
- Project progress reporting
- Force account coordination
- Field testing
- Data management
- Project closeout
NYCT Williamsburg Bridge/BMT Line Reconstruction
Manhattan/Brooklyn, New York
SYSTRA was the rail systems expert on the team responsible for providing construction management services for Contract Package 6 on the Williamsburg Bridge Reconstruction project. This multi-phase project involved the reconstruction of the main bridge span and approaches, including the demolition and reconstruction of NYCT’s BMT line over the bridge between the Essex Street Station in Manhattan and the Marcy Avenue Station in Brooklyn.
SYSTRA was responsible for construction inspection, system start-up and cut-in, and resident engineering services for all rail construction work, including trackwork, signals and communications systems, and traction power. Due to the fact that the entire bridge structure suffered from delayed maintenance over the years, the rehabilitation of roadways, suspension cables, and transit structures and systems were phased in order to provide minimal disruption to train and vehicular traffic. Additional work involved the demolition of the existing structure on the approaches and partial demolition on the main bridge span, and its replacement with a new steel structure on new concrete piers at the approaches and on rehabilitated steel girders on the bridge's main span. The project also included the construction of three new Central Instrument Rooms (CIRs) to house elements of the new signal system, new duct bank for electric traction power, and new trackwork and third rail power installation. The signal system—including modifications to two major interlockings—was replaced, along with communications facilities and fiber optic lines.
The majority of the work, including system start-up, was scheduled during a five-month shutdown of the line. SYSTRA—through careful planning—was able to reduce the shutdown period to four months, which resulted in NYCT's operations on the Williamsburg Bridge resuming a month ahead of schedule.
