South Chiller Plant Expansion

The project design incorporates the following components: three 4,000-ton counterflow cooling tower cells with stringent sound requirements due to the location of the plant with respect to the campus property line; three 9,000-gpm distribution pumps with variable-frequency drives for speed control; provisions for future installation of an ice or chilled-water storage system; a micro-processor-based distributive control system; connection to the campus' existing 12.47 K/V electrical distribution system, including a 7,000 K/VA Phase I addition and 15,000- K/VA ultimate capacity; and sectionalized electrical systems utilizing multiple transformers and redundant primary feeder sources.

About the Reported Cost Figures

The cost figures reported are supplied by the firms that submitted these projects for publication, which in most cases are the designers or builders. Whereas these sources are intimately familiar with their projects, they may not be fully aware of the owners' finally-realized and recorded costs. In some cases, costs are truly and completely accounted for, and in others they represent a near approximation of the final costs. Costs have not been adjusted for year of construction, nor has any attempt been made to make regional cost adjustments.

Further, costs are not comparable on any kind of detailed standard costing model. Hence, it is possible for the cost of one building to include a steam boiler, while the cost of a comparable building might not include the boiler, if steam is being supplied from an already existing campus grid. Or, in another case, a building might include excess boiler capacity to supply steam to another building. Some submittals include fees or unusual site improvements as part of the construction costs, which others do not.
