Other Specialties
As a full-service firm, Judlau’s expertise covers a range of utility and capital improvement work, including railroad signal updates, relays, switches, pump stations, ventilation plants, communication systems and electrical projects.
We were proud to play a part in the reconstruction of the #1 and # 9 subway lines in Lower Manhattan in aftermath of the September 11, 2001 tragedy. Judlau constructed a new relay room, and worked on the installation of signal stops, switches and wiring to put in place a complete working signal system, with tie-ins to the existing system.
On Long Island’s Nassau Line Reconfiguration Project, Judlau transformed a double platform station into a single platform station by cutting a switch into the existing line with new tracks and signals. To avoid delays to normal passenger traffic, we built a new relay room of each line, over a single weekend.
The Company’s integral pump room rehabilitation projects involve the installation of pumps to remove rain and ground water from the subway system. The work involves the installation of temporary pumps, total reconstruction of the pump room itself, plus additional equipment and discharge lines. The construction of lift station for sewage treatment is yet another niche specialty.
Judlau’s newly built vent plants provide fresh air to subway and tunnels, and may be used to extract dust and smoke from the system. Sometimes as large as a city block, these underground vent plans require expert construction and the installation of several large fans, along with air plenums, custom electrical and control systems.
Judlau has been involved with a number of significant communication projects for the Metropolitan Transportation Authority and other organizations. For example, the company installed a complete closed circuit TV system for nine stations to allow for remote monitoring by New York City Transit.
Looking ahead, Judlau fully expects to bring its wide-ranging expertise in these important specialties to new projects in the northeast and throughout the nation.
