The FBI-confirmed surge in U.S. mass shootings—up from an average of 6.4 incidents annually (2000-2006) to 16.4/year (2007-2013)—and other acts of domestic terrorism have public safety officials upping their game in terms of incident response, real-time surveillance, and victim rescue.
In Salt Lake City (Utah), this enhanced approach response is embodied in the new Salt Lake City Public Safety Building (PSB). Opened in July 2013 and now in full service, the four-storey PSB is home to Salt Lake City’s police, fire, and EMS departments; plus all three departments’ integrated 911 dispatch center. Built for $125 million, the 335,000 square-foot PSB (including 172,000 square feet of occupied space and 143,000 square feet of basement parking) has been specifically designed to respect the lessons of 9/11, while having a minimal impact on the environment. These twin goals have been achieved by building a comprehensive level of resiliency into the PSB’s infrastructure, while the building falls within net-zero-energy performance and LEED Platinum certification building standards. This means that the amount of power the PSB extracts the environment is covered by the energy it generates through its 380-kilowatt rooftop solar panels and nearby one megawatt solar farm, plus the power saved through its energy-efficient design.
From an AV standpoint, the Salt Lake City PSB represents a state-of-the-art, integrated approach to incident management. The heart of the facility is the PSB’s two-story Salt Lake Information Center Emergency Operations Center, which is built around a massive Christie MicroTile video display wall that dominates the room. The EOC is supplemented by the Incident Command Room with its two large-screen projection systems, and more. From an audio-video standpoint, the Salt Lake City PSB represents a state-of-the-art, integrated approach to incident management. The heart of the facility is the PSB’s two-story Salt Lake Information Center Emergency Operations Center, which is built around a massive Christie MicroTile video display wall that dominates the room. The EOC is supplemented by the Incident Command Room with its two large-screen projection systems, and the Media Briefing room with its 3-by-3 video wall.
“Add AV-equipped conference rooms and community spaces, and the Salt Lake City PSB is a show piece for what technology can do to enhance public safety,” said Gerald Nelson. He is Principal of Spectrum Engineers; the Salt Lake City AV design/ and engineering firm that designed the PSB’s AV systems. “It is a secure, resilient, and centralized operations center for all of Salt Lake City’s public response agencies—and its best hope for dealing effectively with domestic terror incidents and natural disasters.”
AV IS KEY
The guiding strategy behind idea of the Salt Lake City PSB is for the city’s public response agencies to know what is going on, to respond to developing situations quickly, and to monitor how these responses are unfolding in real time. As well, the advent of camera-wearing first responders, 4G/LTE cellular telephone networks, and multimedia data/ voice communications means that the PSB’s SLIC/EOC team can be fully connected to what is going on, and deal with it accordingly.
The Operations Center is the nerve center of the entire complex. This is why it is equipped with a 77 unit Christie MicroTile video wall, a Crestron DM-MD64x64-RPS64 x 64 HDBT matrix switcher (all AV systems within the PSB are controlled using Crestron Fusion asset management software), and a sophisticated multi-window processor. “The display wall is used to display high resolution content originating from operator consoles, city cameras, television broadcasters, and other similar sources,” said Nelson. “They can display up to 20 different images/video feeds at a time.” The room’s AV system is controlled using Crestron TPMC-9 desktop and wall-mounted touch panels.
As needed, the Christie MicroTile video wall’s display surface can be shared across multiple video and still image windows. Thanks to the MicroTile’s modular plug-and-play design, it is easy to service and replace individual units while the video wall is in use. “This ensures that any display issues can be quickly resolved,” Nelson said. “When there is a serious incident underway, the last thing PSB officials need is a video display failure.”
Video is also central to the Incident Command Room, which uses two Christie digital projectors to fill up its massive screens, and the Media Briefing Room. Unlike the Incident Command room, the Media Briefing Room relies on a 3-by-3 video wall made up of Sharp 55-inch monitors. “The 3-by-3 video wall and professional speaker system is used to efficiently disseminate video and audio subject matter,” said Nelson. “With studio lighting and direct feeds to media trucks, information is immediately shared with the public.” Spectrum Engineering opted not to use projection TVs in this room, for fear that the TV crews’ bright lights would wash out the displays.
Beyond these spaces, there are HDTV displays of various sizes and capabilities through the PSB. This is why effective RF distribution matters: “High resolution signals are shared between the Operations Center and other rooms using a high resolution distribution system,” said Nelson. “Approximately 120 display devices strategically located throughout the facility can receive and display signals from the operations center.”
Serving all these displays with HDTV signals proved to be a head-scratcher for Spectrum Engineers. Not all of the displays have the ability to decode all of the major HDTV audio formats being served through the PSB’s RF distribution plant. Without some form of technical solution, some of the displays would not be able to play the audio being sent to them.
To address this challenge, Spectrum Engineers specified eighteen Contemporary Research 232-ATSC+1 HD tuners in various AV systems throughout the building. “The Contemporary Research 232-ATSC+1 HD tuner is able to decode digital audio in the audio format required for RF TV distribution on this project where tuners from other major manufacturers could not,” said Nelson.
Videoconferencing (using Cisco TelePresence equipment) is also central to the PSB’s operations. “Multiple standard conference rooms and video conference rooms supplement the safety personnel activities and provide efficiencies with rich intercommunication, staff presentations and training,” Nelson said. Mindful that may public safety personnel carry their offices in their smartphones, “almost all rooms are equipped with wireless video mirroring systems (BYOD) to provide simple and timely display of content from personal devices.”
Video may be King of the Salt Lake City PSB, but audio is certainly Prince. “Various audio systems amplify media content audio for listeners throughout the building,” Nelson said. “In addition, personnel in the Operations Center can listen to audio privately over multichannel digital infrared headsets.”
RESILIENCY IS KEY
When the terrorist attacks occurred in Manhattan, one of the casualties of the World Trade Center attack was the New York City EOC located in World Trade Center building #7, which eventually collapsed. The loss of that facility resulted in a mad scramble for a new EOC, one that was eventually set up in a warehouse at Pier 92.
The lessons that 9/11 taught emergency managers are well represented in the Salt Lake City PSB. This building is extremely tough. In fact, the PSB can withstand an earthquake up to 7.5 in magnitude thank to its 52 shocking-absorbing “seismic dampers.”
Meanwhile, backups are the rule of the day at this complex. The PSB is equipped with two 1.56 megawatt diesel generators able to power the entire building. At the same time, the facility is equipped with an energy management system that will shut down non-critical areas automatically, conserving diesel fuel to maximize the PSB’s off-grind operational life.
“The Salt Lake City PSB is built to withstand both the onset of serious incidents, and to go the distance in managing them,” said Gerald Nelson. “It is not enough having state-of-the-art AV if your facility fails the first time the going gets tough.”
Besides extensive video, various audio systems amplify media content audio for listeners throughout the building. Building such a sophisticated public safety facility is difficult under ideal conditions. But things were not ideal for the Salt Lake City PSB AV installation. Specifically, “the Crestron DM digital matrix switchers that were advisable when we built the PSB only went up to 64×64,” said Nelson. “So we had to use numerous DMs located across the facility. Today, you can get more capacity, but that wasn’t the case back in 2013.”
On a larger scale, money was a challenge. “When you are working on a big publicly-funded project like the PSB, budgets are always an issue,” said Nelson. “The public officials in charge understandably want to be seen as being prudent and wise stewards of the public purse. Unfortunately, this prudence led to money being tight in areas where it challenged us in meeting the project’s goals. Ultimately we made it happen, but it wasn’t easy.”
Moving to the PSB was a “quantum improvement in capabilities” for the staff. Finally, once the PSB was built, it took a while to get its staff to use all of its capabilities. “The Salt Lake City personnel came from an old, cramped, and dated facility where it was hard for them to do as much as they had to,” Nelson said. “Moving to the PSB was a quantum improvement in capabilities for them, one that took a lot of training to get them to use fully.”
Today, Salt Lake City’s emergency management personnel have embraced everything that the PSB’s powerful AV capabilities can do for them, “and they are elated with the results,” said Gerald Nelson. “Salt Lake City is definitely a safer and more prepared community, thanks to the opening of the PSB.”
