Naming the project improves communication and distinguishes it from other activities.
The three "Rs" denote Repair, Renovate, and Reconfigure. The University project designation
for this effort is OSU-
The project has been subdivided into two main phases. In concept, a third phase may follow dependent upon the results of the first two phases.
Many performance issues stemming from multiple root causes are present in the current systems. These issues have caused, among other things, premature deterioration of the machines to such a degree that an urgent need to halt this condition is now present.
The project seeks to remedy the underlying performance issues and to normalize the projected life span of the air handlers.
Phase 1: Creates a new air inlet north of the patio -
Phase 2: Focuses on AH-
on consecutive weekends in November. See project timeline for details.
Phase 3: Conceptual only. No design, schedule, or funding currently planned.
Phase 1 work was done in the main air inlet plenum and can be seen in completed form
near the north edge of the patio. Phase 2 will be work done within the internal space
of AH-
The project hopes to meet its goals by completing the following actions in the air
systems and/or within AH-

Total costs ~$900k split as Ph. 1 = ~$300k, Ph. 2 = ~$600k, Ph. 3 = $TBD (unfunded).
The funding is provided under the University/FOD Repair and Renovation (R+R) program.
