Partitions: Other Design Criteria
(See Section 335.1.) Conversely, walls without the same critical
acoustic requirements may contain services within them without
jeopardizing the required performance.
6. Rate of Change of Services. Where the rate of change of services is
not expected to be any greater than that of the partitions (e.g. room
thermostats, or switch drops) and where other performance
characteristics are not jeopardized, services may be housed within
partitions.
7. Costs. An example showing the installation cost of surface mounting
services compared with housing them in partitions is described in
Section 780. Installation costs for surface mounting are greater but
alteration costs are reduced because services can be changed more
simply and quickly (with minimum disruption in the functional area) and
because materials can be reused.
