J&M Brown Completes Electrical Construction of One Congress in Boston

One Congress

Boston – J&M Brown Company (JMB) announced it has reached substantial completion of the complex core and shell electrical construction of One Congress, the centerpiece project in Boston’s Bulfinch Crossing.

Designed by architectural firms Pelli Clarke Pelli and CBT Architects and rising to 600 feet, the new, 43-story, 1,006,500sf office tower is the tallest high-rise constructed in Boston in more than 40 years. One Congress has received LEED Platinum certification.

JMB’s comprehensive electrical project scope entailed installation of the building’s primary and emergency power systems, electrical distribution, interior and exterior lighting and lighting control systems, as well as the building’s fire alarm/life safety system. JMB also provided electrical infrastructure for the building’s A/V, security and tel/data systems.

Primary power is provided via a 13.8KW/480V transformer and electrical distribution system. For emergency and standby power, the building is equipped with five rooftop generators: a 1,750KW generator for the base building and four 750KW generators for tenants.

JMB’s expansive electrical construction included the installation of approximately 200,000 linear feet (more than 37 miles) of conduit and 500,000 linear feet (more than 94 miles) of wire. The building’s interior lighting package features more than 6,000 LED light fixtures and drivers, controlled by an advanced multiple-zone Lutron lighting control system. Exterior lighting at One Congress features customizable, color-changing facade uplighting.

At peak construction, JMB managed a field crew ranging upwards of 50 IBEW Local 103 journeymen and apprentice electricians on the One Congress base building project. The NECA contractor’s crews worked more than 165,000 man-hours in meeting the scope and owner timeline requirements. The project commenced in November 2019 and project owners Carr Properties and National Real Estate Advisors took occupancy in May 2023.

The JMB project team was headed by project manager Ed Zipper, project supervisors Wayne Lucas and Daryl Weiss, and foremen Mark Nicolas, Bill Patterson and Eamonn McDonagh. JMB worked in close coordination with the project’s general contractor, John Moriarty & Associates (JMA) and the project’s subcontractors. The HYM Group is the developer of One Congress.

In addition to its first-class office space, One Congress features a 15,000sf outdoor rooftop terrace and a full-floor amenity center on the 11th floor comprised of a 7,000sf fitness center, event and conference space, and a full cafeteria.

One Congress is the new international headquarters facility for primary tenant, State Street Corp., which occupies 27 floors comprised of 450,000sf in the office tower. Concurrent to the core and shell electrical construction of One Congress and under separate contract, JMB, teaming with JMA, is also substantially complete with the electrical fit-out of the State Street offices.

The project electrical scope included installation of a separate electrical distribution riser backed up by two roof-mounted generators and an 800KW Uninterruptible Power Supply System. The extensive lighting package for the State Street project included installation of 5,000 fixtures with the longest fixture run being 190 feet. The lighting control system provides control of 22 floors as well as integration with AV systems for conference rooms, training rooms and executive rooms. Custom lighting was provided for a video studio. The base building fire alarm integrates to all State Street offices and the project included installation of a fire suppression system for the full kitchen.

JMB project manager Nelson Barrantes and general foreman Phil Talbot headed the project team, supervising a separate JMB crew of 45 IBEW Local 103 electricians at peak construction. The State Street office build-out commenced in June 2021 and the project was complete in May 2023.  The phased-occupancy project allowed for State Street to take occupancy of 10 floors of the offices during the course of the fit-out. State Street Corp. took full occupancy of its new headquarters in late spring 2023.  The new office tower will accommodate at least 2,500 State Street employees.

Also at One Congress, JMB, working with general contractor Structure Tone, recently completed a two-floor fit-out for law firm K&L Gates. And teaming with Elaine Construction, JMB is also underway with the two-phase, 13-floor, 250,000sf electrical fit-out for medical software and data management company InterSystems. Phase one, floors 32-36, will be completed in December and phase two, floors 37-43, is scheduled for completion in late 2024.
