As part of the New York City Fire Department’s radio communication recommendations after Sept. 11, 2001, TSEC and EJCI completed services to develop land mobile radio sites for the city of New York Department of Information Technology and Telecommunications (DoITT) Emergency Radio Communications System. TSEC and EJCI designed 16 of the 32 sites for the Channel 16 project — implemented by Motorola — for DoITT’s critical radio communications for emergency services and first responders. Our team designed the infrastructure needed to support the space renovation and installation of power, air conditioning, fire protection and structural support. TSEC and EJCI provided program management, design, construction services, zoning and permitting support. TSEC and EJCI also assisted Motorola with cable management and other services for various radio sites for the 800-MHz Emergency Radio Network. The 800-MHz sites transmit and receive critical radio communications for life safety radio communications.


DuPage National Technology Park Cyber Continuity Center

TSEC and EJCI provided mechanical, electrical and plumbing engineering services for the design of a new 60,000-square-foot, Tier III data center at a new technology park in DuPage County, Illinois. Our team’s services included design, preparation of construction documents, permitting assistance and construction support.

The building design is able to support up to 4.8 megawatts of critical load with an average power density of 133 watts per square foot throughout the 36,000-square-foot, raised computer floor. The critical infrastructure is concurrently maintainable with redundant uninterruptible power supplies, redundant standby generators capable of supporting the facility and redundant chillers, pumps and cooling towers providing chilled water through primary and alternate distribution piping paths. Heat exchangers are included to provide water-side economizer for energy savings. A building management system was designed to integrate, operate and monitor the various systems. TSEC and EJCI also assisted with zoned fire detection as well as alarm and suppression systems, including pre-action and clean-agent suppression.

Indiana Hoosier SAFE-T – Emergency Communications System

Project Hoosier SAFE-T (Safety Acting for Everyone Together), a statewide radio communications project, allows reliable communications among local, state and federal public safety agencies during routine, emergency and task force situations — strengthening community safety and security, reducing costs and barriers to communications and breaking down regionalization of systems to combat crime, natural disaster and terrorism.

TSEC and EJCI served as the program manager/tower integrator for this statewide, interoperable, wireless public safety communications system. Our team identified approximately 160 sites that require enhancements or additions to existing or new emergency communications facilities and antenna towers. We confirmed the site’s suitability, secured properties, designed facilities and improvements, prepared construction drawings, obtained permits, coordinated utilities, provided construction services at each location to accommodate Motorola's radio equipment and created a GIS database of tower information for our client.

International Broadcasting Bureau – Kuwait transmitting station

As team members with Thomson Broadcast & Multimedia, TSEC and EJCI provided engineering and construction management services for the expansion of the International Broadcasting Bureau station in Kuwait. The station broadcasts Radio Free Afghanistan and provides other broadcasting services sponsored by the U.S. government. TSEC and EJCI also designed the initial station under a separate subcontract.

The station’s capabilities were expanded to include shortwave broadcasting. Our team assisted with planning, site investigation, design and construction documentation, construction support, cost and schedule control and systems/equipment integration. TSEC and EJCI also helped to expand the infrastructure at the station and design the permanent transmitter facility, replacing the interim facility in the mid-1990s. The design included future expansion capabilities, such as 10,500-kilowatt high-frequency transmitters, transmission lines and switch bay, 15 pairs of high-frequency fixed-curtain antennas and all necessary broadcast support subsystems and facilities.


International Broadcasting stations

TSEC and EJCI has completed approximately 50 projects worldwide for the Broadcasting Board of Governors and the International Broadcasting Bureau. Our team offers services in support of IBB projects such as facilities engineering, project management, scheduling, reporting, budgeting, testing and commissioning. 

We work with major international companies and participate as a key team member in systems integration, installation and construction of broadcast stations for acceptance by the U.S. government. This includes numerous projects for the Voice of America, a multimedia international broadcasting service funded by the U.S. government that provides thousands of hours of news, educational and cultural programming for audiences worldwide.

U.S. Coast Guard – LORAN-C high-power transmitter stations

The U.S. Coast Guard selected TSEC and EJCI to complete engineering, architectural design, electrical and mechanical services for new transmitter buildings, power plants and renovations at remote LORAN-C stations at Attu, St. Paul and Port Clarence, Alaska. LORAN-C stations provide the U.S. Coast Guard with radio navigation services for U.S. coastal waters and beyond.

This project entailed developing new facilities to house high-power solid-state transmitters while maintaining operations for the existing transmitters. To reduce potential station outages, TSEC and EJCI also assisted with detailed project phasing and a systematic changeover plan to decommission equipment and commission new equipment without interrupting operations. The projects also included:

  • Designing three new primary power plants. These plants consisted of three 350-kilowatt engine generator sets designed to operate 365 days a year;
  • Designing a special ventilation system with air intake hoods and enclosures to prevent the intrusion of windblown water and snow;
  • Installing a new fuel delivery system that provides a two-year resupply operation via oceangoing barges;
  • Developing an intensive fire protection system — a 30,000-gallon underground water supply tank, fire pump, pre-action valve system and water piping system. These components operate in conjunction with a cross-zoned ionization and heat-detection system;
  • Incorporating an air-conditioning system for internal transmitter cabinets that uses halon as an extinguishing agent; and
  • Developing a step-by-step changeover plan resulting in the decommissioning of equipment and the commissioning of new equipment without interrupting operations.
