Service Zone: The service zone is organized into subzones and channels that define and or-
ganize the service runs. [Refer to details in Appendix C. Refer to Appendix A for examples in
existing VAHBS hospitals.] Subzones are horizontal layers within the service zone. Main service
distribution runs from the service bay are all parallel, each connecting to branches at right angles to
the mains, and branches connecting, where required, to laterals at right angles to the branches
within the defined subzones. Channels are plan divisions of the subzones and define reserved lo-
cations for particular services.
In order to preserve the rights-of-way for initial and future installation of service runs, no shortcut or
point-to-point routing of services is permitted. This is extremely important.
