Computer-Aided Dispatch

Implementation of the new computer-aided dispatch (CAD) system was a significant, multi-year, technical undertaking that involved multiple phases, multiple agencies, and many hours of training, with particular attention to system integration. Committees were formed with decision-makers, technical staff, and field and dispatch users, to ensure transitions would be successful.

"Interoperability is a cornerstone of South Sound 911 and why the agency was formed," South Sound 911 Executive Director Andrew Neiditz said. "It is a significant accomplishment for all public safety agencies to have worked together toward this common goal, which ultimately helps make our communities safer."

As of April 11, 2017, South Sound 911 and all of its police and fire agency partners were using the new CAD system. The system is maintained by dedicated team within the Communications Systems department.
 
Now that all local public safety agencies are operating on the new CAD system, collaboration will continue as agencies look to improve operational efficiencies for call handling and dispatch. For the time being, however, fire and medical aid calls will still be transferred to fire dispatchers, as has been the process in Pierce County.

South Sound 911 uses a CAD system from Hexagon Safety & Infrastructure. The estimated cost was $5.35 million.

Implementation for Law Enforcement Services


Law enforcement agencies dispatched by the South 35th Street Communications Center migrated to the new Hexagon Safety & Infrastructure (HSI) platform at 5 a.m. on Oct. 13, 2015, followed by the agencies and dispatch staff at the Eastside Communications Center on Oct. 19, 2015. Agencies dispatched by the Fife branch migrated to the new system on Oct. 28, 2015.1 

It took time for communications staff and officers in the field to get used to the new system; it was a major change from previous systems.

"This is a huge deal to bring us all together under the same [CAD] system," Puyallup Police Officer Dan Pashon told KING-5 News. "When we have a critical incident, when we have to get officers from different agencies to respond, we had to exchange that information through telephone calls, through dispatch centers, who will then get that through the radio. Now, we're all on the same system."

South Sound 911 continues to work with staff from HSI for system adjustments while dispatch and law enforcement staff provide feedback from real-life use.
Staff from HSI were on-site for two weeks providing implementation support and assistance and returned the following month to work on adjustments suggested by users. Additionally, South Sound 911's own technology staff continually provides support and develops custom enhancements and solutions.
1 The Fife branch later closed in late-2015 and employees moved to the Eastside Communications Center. In May 2017, all law enforcement 911 and dispatch consolidated in the former South 35th Street Communications to form South Sound 911's unified Law Enforcement Communications Center in Tacoma.

Implementation for Fire Services


South Sound 911's Fire Communications Center (formerly West Pierce Fire & Rescue Fire Comm) was the first fire dispatch center to move to the new CAD system at 5 a.m. on Nov. 1, 2016, along with the 18 fire districts they dispatch. This marked the first time both fire and law enforcement responders in Pierce County have been on the same dispatch system.
 
The time between law and fire dispatch implementations allowed for more hands-on training with fire agency users, as well as dedicated HSI on-site support during the cutover.

Tacoma Fire Communications later transitioned to the new CAD system on April 11, 2017. Tacoma Fire Communications dispatches for the Ruston Fire Department and the Tacoma Fire Department, which also provides fire and EMS for the cities of Fife and Fircrest.
A fire dispatcher tries the new CAD system on Nov. 1, 2016.
Both fire communications centers and their field users will go through post-implementation processes similar to the law enforcement users. This process allows for user feedback to be collected so the system can be further fine-tuned and enhanced to better meet their needs.

Project History


In early 2011, the Public Safety Answering Point (PSAP) Managers Group formed a recommendation committee to collectively evaluate CAD systems in support of interoperability, information-sharing and standardization - key capabilities that support South Sound 911's mission and vision.

After a series of vendor demonstrations and issuance of a request for proposals (RFP), South Sound 911 selected a CAD system from Hexagon Safety & Infrastructure (formerly Intergraph Corporation). The new CAD system will provide a unified platform for Pierce County's 160 dispatchers and call takers and over 1,800 law enforcement and fire/EMS first responders.

"Interoperability, information sharing, and standardization are some of the key capabilities we sought to support South Sound 911's mission and vision," Executive Director Andrew Neiditz said when the CAD vendor was announced. "This technology will allow us to assign resources from any or all agencies to a single incident, providing better protection for our first responders and safer communities."
A project team was formed in 2014 which includes representatives from South Sound 911, West Pierce Fire & Rescue's Fire Comm, Tacoma Fire Communications, Puyallup City Comm, and the City of Buckley. The team facilitates and coordinates various aspects of the project’s implementation including training, geographic information system (GIS) functionality, field use, dispatch, and network and phone/radio integration. Dispatch and field personnel from numerous law enforcement and fire agencies participated in several interdisciplinary configuration sessions in 2014 to help create a state-of-the-art design that will best meet operational needs and desired functionality.
 
The involvement and collaboration of dispatch and field personnel in the configuration process has been and will continue to be critical to the success of the new regional system. Configuration efforts continued into mid-2015 and intensive training of the nearly 2,000 users of the system spanned several months leading up the to the first go-live in October 2015.
