Fischbach & Moore's largest ongoing project is the massive, high profile project is the ventilation system for the Central Artery Tunnel. The project scope calls for Fischbach & Moore to furnish, install and test the entire ventilation system of the nation's largest public works project. Fischbach & Moore is serving as both the general contractor and electrical contractor of the project which is considered one of the world's largest, most complex tunnels.

The immense ventilation project incorporates the installation of 95 double width, double inlet centrifugal fans, 35 jet fans and 8 vane axial fans, as well as all of the associated power and control equipment. These components are the first to be installed as part of a tunnel ventilation system in the nation. This elaborate system is engineered to serve both as a tunnel ventilation system, supplying fresh air and removing vehicular exhaust, as well as serve a life safety system in the event of a fire. The ventilation system features a state-of-the-art monitoring system, as well as the use of a reversible vane axial fans that will be integrated into the various ventilation structures of the existing South Station Tunnel to support the new southbound lanes of Interstate 93. These fans will serve as both supply and exhaust fans in the particular roadway sections.

When completed all ventilation and associated electrical work will be further integrated to the Operations Command Center (OCC) of the CA/T, which will serve as the nucleus to the entire tunnel. This is where Fischbach & Moore first partnered with Sullivan & McLaughlin Companies, as a subcontractor by Honeywell Technologies Solutions.

Sullivan & McLaughlin was chosen as the subcontractor for the Big Dig Smart Highway System, the most advanced electronic traffic monitoring and incident response system in the world. Fischbach & Moore and Sullivan & McLaughlin teamed up to install, test, and maintain the myriad of devises located throughout the tunnel and adjacent buildings and connect them to the project's Operation Control Center and Backup Operations Control Center, where all the life safety systems and traffic patterns are monitored 24/7. SullyMac was hired for all the fiber optic splicing, testing, and troubleshooting, as well as the telephone cabling and terminations.

This scope is enormous, as Sullivan & McLaughlin's scope includes the connection of nearly 1,500 previously installed loop detectors, mounting, and connecting 343 CCTC cameras, 287 variable message and lane closure signs, 52 overheight detectors, 98 carbon monoxide detectors, 27 continuous emission monitors and 1734 fire alarm devices. The team also installed 295 roadside communication cabinets, 152 I/O distribution cabinets, 190 building equipment racks located in the vent buildings that connect the highway devices to the control centers. The project also includes the installation of a two-way radio system for Boston Fire Department, State Police and Boston Emergency Medical Services and a tunnel AM/FM radio system requiring over 28 miles of AM radiating cable and 17 miles of sawcutting.

As Prime Contractor, Fischbach & Moore is responsible for all scheduling, quality assurance, lane closures and coordination with the Central Artery/Tunnel project engineers. Fischbach & Moore was able to take on the extreme complexity and logistically challenges of this massive undertaking as the project is a schedule and in its final stages.

The Personnel Protection System for Deer Island Wastewater Treatment Facility is one of the most intriguing projects in Fischbach & Moore's long list of achievements. This project is best known for its technical complexity.

This seven year, $13 million project involved the installation and integration of five different systems: an island wide fire detection and signaling alarm system, CCV, paging system, card access security system, and telecommunications system.
