New Police Department

City of Rock Island

IMEG provided engineering design and services for the City of Rock Island’s new police station. The $20 million, 44,500-sf building doubled the space available to the police department, which had outgrown its current, 22,000-sf, 75-year-old facility. The new building and its modern technology allows the department to increase efficiency and upgrade services to the community.


The police station includes offices, interview rooms, holding cells, training and simulation areas, a weight room, locker rooms, and 911 communications center. An existing 12,000-sf warehouse located on the 4½-acre site was renovated to house the crime lab and evidence processing and storage areas.


IMEG provided MEP, fire protection, technology design, and construction administration services, and is currently providing commissioning services for the new building and renovated warehouse. The firm collaborated with the architect, owner and end-users in group meetings to ensure the design met the unique requirements of the different divisions and spaces within the building, including:


  • 911 communications center. The most critical area of the building, the center was designed in accordance with NFPA 1221, “Installation, Maintenance and Use of Emergency Services Communications Systems.” This includes fully-redundant HVAC and emergency power systems.
  • Prisoner processing and evidence areas. These areas include additional security measures related to the infrastructure, in addition to “detention-rated” fixtures such as remotely-operated lavatory controls.
  • Crime lab and evidence processing. These areas include specialty exhaust systems and fume hoods for the drug lab and finger printing stations, and digital evidence tracking.


All design met the baseline standards of the 2013 International Energy Conservation Code. Energy-efficient features include vacancy sensors, low-flow plumbing fixtures and LED lighting in some areas.


Key mechanical systems include three 1500 kBtu natural gas boilers (providing a total of 135 BHP) for hot water heating and reheat; packaged rooftop AHUs (four total) with DX cooling, and a dedicated conditioning system and clean agent fire suppression system for the main server room, which also houses the emergency communications equipment.


The technology design supports the building’s high-level security features including all access control and door hardware coordination, security address systems, video surveillance cameras, duress buttons and silent alarms.
