Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
DEFINITIONAL ISSUES AND POTENTIAL REVISIONS 37 CCF is the condition code factor CRV is the replacement cost of the facility n = the number of facilities in the real property database Condition Code 18 5 Excellent; no work required. 4 Good; less than 10 percent of components need repair. 3 Fair; more than 30 percent of components need repair. 2 Poor; greater than 30 percent of components need repair. 1 Unserviceable; failed system overall. System Weights 19 40% Structural 30% Mechanical 30% Electrical The condition code factor is assumed to be a decaying exponential function as the cost to repair increases dramatically with deteriorating condition: CCF = k1e { [k2 (1 ` NCC)]} Where: k1, k2 = constants, assumed to be 1; exp = âeâ or 2.718. and NCC= Net Condition Code (sum of condition codes times system weights for each sample facility averaged for sample size) Sample Calculation Parameters: Assume an inventory of 100 facilities, $100M total current replacement value, and a 1 building sample. Mechanical assessment: Failing heating units, aging unreliable chillers. Condition Code = 3 Electrical assessment: 2 systems need replacement. Condition Code = 4 Net Condition Code (NCC)=((3 Ã 0.4)+(4 Ã 0.3)+(3 Ã 0.3))/1=3.3 CCF=exp(1-3.3)=0.10 (10%) Where: k1, k2 are assumed 1 for this example BMAR=($100M)(0.10)=$10M 18 The condition code factors and parametric weights are provided for illustrative purposes only. Each agency would need to develop its own set of condition code factors/parametric weights. 19 The condition codes for system weights are provided for illustrative purposes only. Each agency would need to develop its own set of conditions codes.
