One of the purposes for this contract is to maintain Installation Building Control systems inside the DSCC buildings on Columbus, in an operational state of readiness. Sustainment of Building Controls shall include three types of services;

Software Maintenance, Operational Support, and Scheduled Tasks.

a) Software Maintenance Software Maintenance includes patching of the servers, firmware upgrades to the building level controllers, and software patches to Workstations. This work will be completed by a DoD 8570 certified worker as defined under Personnel Security Requirements, Cyber Security Strength Requirements, and the Risk Management framework sections below.

b) Operational Support Support is scheduled or unscheduled work. This work would typically be in response to a failed or failing component. Provide review of the system alarm conditions with in-house maintenance group, identify if the alarm responses can be completed in-house, and what level of operational support is required. Provide graphic and programming changes to eliminate overrides, add new or subtract equipment to/from the system, including programming, graphics, updating local and server level software/firmware. This will also include the ability to support additional items above those defined in the contract on a unit price basis. All the work described above would be scheduled work completed by a DoD 8570 certified worker. In the event an instrument, control component, or controller fails during off-hours operation and these components or systems are deemed critical to the mission, the COR would identify this as unscheduled work.

c) Scheduled Tasks Scheduled Tasks consists of items identified as work to be accomplished as part of this contract.

This will include but not limited to; replacement of additional field controllers during the first and second years of the contract, tying in additional sensors, advanced programming for correcting known deficiencies, integrating buildings as additional fiber becomes available, establishing a global outside air temperature, and global seasonal change command.
