This cost model compares a traditional separate systems installation to a singly designed and installed SCS. The approach can be applied to any new or renovated building project. In this case, the traditional approach uses multiple cable types and delivery methods. The SCS method uses the same cable type for all the voice, data, video, and BMS services with a common delivery method for all horizontal low-voltage and high-voltage services. The SCS open-office cabling approach also provides for additional horizontal coverage with 599 spare outlets.

Premises Configuration	Traditional	SCS
floors	5	5
square feet	100,000	100,000
square meters	9,294	9,294
horizontal cabling	homerun	open office
cable delivery	conduit/tray	raceway
work areas	850	850
voice/data outlets	1,700	1,700
spare outlets	0	599
BMS devices	400	400
electrical circuits	257	257

Table 1. Integrated SCS Cost Comparison

The following three modules contain the construction, labor, and operational comparisons based upon this configuration. Please note that the actual level of savings achieved depends on the configuration and the actual prices for material and labor. Also note that the spare-outlet capacity can be adjusted to meet customer needs, but 25 to 35 percent of the total voice, data, video, and BMS outlets is recommended. All cabling and delivery methods are installed in an access ceiling for this example.
