Does the construction of a telecommunications equipment room require approval
There must be at least one telecommunications room (TR) in a single-story building. For multi-story buildings there must be one TR on the first floor (or basement). This section includes the specifications for constructing and building out of Telecommunications Equipment Rooms (MDF/IDFs) to be used for supporting telecommunications and other special systems. Anti-static/grounded VCT to be installed early. This approval process is called telecom permitting. Telecom permits confirm that new infrastructure follows safety rules, zoning laws, and environmental regulations. It does not apply to work subject to a building notice, full plans application or initial notice submitted before that date. The telecommunications space is an enclosed architectural space for housing communications cabling, cable terminations, and cross-connect hardware and telecommunications electronics.
