It is also important to evaluate the operational costs associated with moving, changing, and rearranging the voice, data, and electrical services. The costs depicted in this example are based on typical United States labor rates for the actual work to be accomplished and do not include visit charges. The comparison assumes that 15 percent of the work areas will be new and that the remaining 85 percent will be rearranged or reused. One work area consists of a voice, data, and dual electrical outlet.

If 40 percent of the work areas experience these changes (churn) over a one-year period, the SCS operational savings amount to 34 percent. When projected over a five-year period, the savings are not only substantial but allow the building owner or manager to quickly respond to changes requested by occupants.

Operational Costs per Work Area	Traditional	SCS	Savings
cost per new work area (15 percent)	$202	$132	$70
cost per rearrangement (60 percent)	$88	$44	$44
cost per reuse (25 percent)	$20	$40
40 percent churn of work areas five-year operational costs	$184,224	$121,459	$62,765
SCS operational savings			34 percent
