SUBJECT:
Aurora Police Headquarters Automated Building Controls Upgrade.
PURPOSE:
To obtain authorization to upgrade the existing automated building controls at the Aurora Police Department Headquarters.
BACKGROUND:
When constructed, the Aurora Police Headquarters was equipped with a Trane Summit building automation system (BAS) to monitor and control numerous heating, ventilation, and air conditioning (HVAC) appliances. This system has performed well but as of May 2017, is obsolete with a limited supply of replacement components, and the software will not be supported beyond the Microsoft Windows 10 operating system.

The greater control capabilities will result in improved system management, reduced energy costs, and enhanced personnel comfort. The proposal includes operator and user training. The proposed cost to upgrade the system is $76,523.00 and a City of Aurora ten percent (10%) contingency of $7,652.30 for a total of $84,175.30.
