• Removal of existing clean agent fire suppression system, including cylinders, piping, and controls
• Removal of existing fire alarm equipment, including detectors, annunciators, and controls. Provision of: new custom factory fabricated Air Handling Unit (AHU); two new chillers with integral pumps and hydronic equipment; new VAV terminal units and motorized dampers, two new outside air supply fans with duct-mounted electric heating coils; one new direct expansion Fan Coil Unit (FCU); one new Variable Refrigerant Flow (VRF) system with four indoor units; one new and complete Direct Digital Control (DDC) system; new dampers and controls to integrate with the clean agent fire suppression system; revisions to existing ducts and equipment; and all material and appurtenances to support the aforementioned work
• New equipment and revisions to existing electrical equipment to provide electrical service to the above equipment
• New clean agent fire suppression system, including cylinders, piping, and controls
• New Fire Alarm (FA) system, including space-mounted smoke and heat detectors, air sampling smoke detectors, annunciators, and controllers
• Removal of existing and reinstallation of existing ceiling tiles and grid; patching of existing walls; painting of new exterior equipment; new structural steel supports; and other architectural and structural work in support of the above equipment

Critical Elements of the Work: The successful Contractor shall be fully qualified to install critical elements of the Work.

• Cultural aspects of the site dictate limits acceptable arrangement of exterior equipment. The indicated exterior equipment arrangement and locations shall be strictly adhered to
• Facility shall have continuous electrical power throughout operation. Electrical power shutdowns to be limited to agreed upon durations.
• Installation of the new fire suppression system shall be phased. The control panel and detection systems shall be installed in their final location, as they don’t conflict with the existing. Initially, some of the new suppression cylinders shall be installed in a temporary location and system commissioned and tested, after which the existing system can be demolished. A second phase shall have the remainder of the cylinders and all of the piping installed. Cylinders that were temporarily installed elsewhere shall then be installed in the storage room. A final test shall be performed.
• During construction of the new FA alarm, the existing FA system shall remain in place and operational to preserve life safety. The existing FA system shall not be demolished until the new FA system has been installed and provides sufficient coverage for life safety.

The Period of Performance for the Base Contract is 570 Calendar Days from the date of Notice to Proceed.

Total Estimated cost range is between is $1M and $5M.
